The income is generated through the sale of Karunya Lottery which is exclusively devoted for extending financial assistance to this purpose. Hence this finance is fully contributed by the public. Kerala government www.selleckchem.com/products/LDE225(NVP-LDE225).html started free karunya dialysis scheme 6 months ago which provide 2 hemodialysis per week irrespective of the residual renal function. We conducted a study to compare

the surogate markers of dialysis adequacy between patients undergoing hemodialysis in karunya dialysis scheme and in private sector. Methods: This was a cross-sectional observational study. All the 83 patients who were undergoing Hemodialysis under karunya scheme in our institution (Government medical college kerala,

India) and 100 patients undergoing hemodialysis in 3 randomly selected dialysis centers under private sector in our city were enrolled into our study. Patients informations were retrieved from from dialysis unit using a data entry form. The information retrieved included patients demographic data, etiology of ESRD, frequency of hemodialysis, types of vascular access used for hemodialysis, frequency of intravenous iron therapy and ESA and the frequency of blood transfusion. The surrogate markers for adequacy Barasertib order like Hemoglobin, ferritin, Albumin, Calcium, phosphrous PTH, lipid profile, signs of fluid overload, uraemic symptoms and biometrics

like midarm circumference, BMI and triceps skin fold thickness were compared between the 2 groups. We also looked at the quality of life based on WHO-QOL BREF questionaries in both the groups. Statistical analysis was done using SPSS version Rolziracetam 21.0. Results: There were no statistical difference between the two groups in all the parameters compared. Conclusion: Karunya free Dialysis Scheme is an effective way for improving the access to maintenance hemodialysis and renal care without compromising on the outcome and quality of life. Hence we suggest karunya model of dialysis to all End Stage Renal Disease (ESRD) patients in resouce poor countries. HUNG CHI-CHIH, CHANG JER-MING, TSAI JER-CHIA, CHEN HUNG-CHUN Division of Nephrology, Department of Internal Medicine, Kaohsiung Medical University Hospital, Kaohsiung Medical University Introduction: Higher hemodialysis (HD) adequacy presented as Kt/V is associated with lower all-cause mortality in observational studies, though randomized HEMO study showed no superior survival of higher target Kt/V group patients (Kt/V 1.65 vs Kt/V 1.25). Some subgroups of HD patients such as Asian people or female may have benefits under higher Kt/V. Thus, we would ask whether higher Kt/V with the dose more than that in HEMO study would be associated better survival after long term follow-up.

The mean number of lymph nodes in quadrants I–IV were 3.3 ± 1.6, 2.0 ± 1.2, 1.5 ± 1.3, and 1.9 ± 1.4, respectively. The difference between the four quadrants was statistically significant (P < 0.001). In quadrant I, the appearance rate of SCIA was 100% while SIEA was 6.6%. In quadrant II, no SCIA was observed but the

appearance rate of SIEA was 78.0%. There were neither SCIA nor SIEA observed in quadrants III and IV. The superior lateral quadrant of the groin region was found to have the most lymph nodes. The superficial circumflex iliac vessels are the major sources for blood supply to this region. The findings from this study provide evidence for the clinical design of the lymph node flap from the groin area. © 2014 Wiley Periodicals, Inc. Microsurgery 34:558–561, 2014. “
“Background: Vascular thrombosis with

PFT�� price flap loss is the most dreaded complication of microvascular free tissue transfer. Thrombolytic agents such as tissue plasminogen activator have been used clinically for free flap salvage in cases of pedicle ALK inhibitor thrombosis. Yet, there is a paucity of data in the literature validating the benefit of their use. Methods: A retrospective review of the breast reconstruction free flap database was performed at a single institution between the years of 1991–2010. The incidence of vascular complications (arterial and/or venous thrombosis) was examined to determine the role of adjuvant thrombolytic therapy in flap salvage. Pathologic examination was used to determine the incidence of fat necrosis after secondary revision procedures. Results: Glutamate dehydrogenase Seventy-four cases were identified during the study period.

In 41 cases, revision of the anastamoses was performed alone without thrombolytics with 38 cases of successful flap salvage (92.7%). In 33 cases, anastamotic revision was performed with adjuvant thrombolytic therapy, and successful flap salvage occurred in 28of these cases (84.8%). Thrombolysis did not appear to significantly affect flap salvage. Interestingly, only two of the salvaged flaps that had received thrombolysis developed fat necrosis, whereas 11 of the nonthrombolysed flaps developed some amount fat necrosis (7.1% vs. 28.9%, P < 0.05). Conclusions: The decreased incidence of fat necrosis may be attributable to dissolution of thrombi in the microvasculature with the administration of thrombolytics. Although the use of adjuvant thrombolytic therapy does not appear to impact the rate of flap salvage, their use may have secondary benefits on overall flap outcomes. © 2011 Wiley-Liss, Inc.

“It is important to preserve the length, appropriate durable skin, and sensation of the stump when performing below-knee amputation to achieve functional ambulation with a prosthesis.

Recent evidence suggests that statins have multiple effects and are able to modulate the immune response independent of their cholesterol attenuating ability [25]. The anti-inflammatory and immunomodulatory Gemcitabine effects of statins stem from downstream effects of inhibiting the mevalonate pathway leading to decreased activity of the small guanosine triphosphate (GTPases) Rac, Ras and Rho [26], which are crucial for many cellular functions including proliferation and transcriptional regulation [27], key processes in inflammation. We hypothesize a beneficial

therapeutic effect of statins in SAg-mediated diseases through the modulation of T cell activation and MMP-9 production. In this study, we studied

the role of atorvastatin in modulating three critical steps in the pathogenesis of coronary artery inflammation and aneurysm formation in a disease model of KD. These include T cell proliferation, TNF-α cytokine production and TNF-α-mediated MMP-9 production [28,29]. We show that atorvastatin inhibits each one of these critical processes leading to aneurysm formation, suggesting a potential beneficial effect of statins in the treatment of KD. Atorvastatin calcium www.selleckchem.com/JNK.html (Pfizer, Kirkland, Quebec, Canada) was dissolved in dimethyl sulphoxide (DMSO) (Sigma-Aldrich, St Louis, MO, USA). Mevalonic acid (MVA) (Sigma-Aldrich) was also dissolved in DMSO, and Staphylococcal enterotoxin B (SEB) (Toxin Technology Inc, Sarasota, FL, USA) was dissolved in phosphate-buffered saline (PBS). LCWE was prepared as described previously [19]. Briefly, Lactobacillus casei (ATCC 11578) was harvested after ∼18 h and washed in PBS. Bacteria lysis by overnight sodium dodecyl sulphate (SDS) incubation was followed by incubation with DNAase I, RNAse and trypsin (Sigma Chemicals) to remove any adherent material from the cell wall. The cell wall was fragmented through sonication in a dry ice/ethanol bath for 2 h. for Phenol-sulphuric colorimetric determination assay was used to determine the measurement of rhamnose concentration,

which was expressed in mg/ml PBS. Total protein concentration was determined using the Bio-Rad Protein Assay (Bio-Rad Laboratories, Mississauga, ON, Canada) following the manufacturer’s instructions. Wild-type 6–12-week-old C57BL/6 mice were purchased from Charles River Laboratories (Wilmington, MA, USA) and housed under specific pathogen-free conditions at the Hospital for Sick Children under an approved animal use protocol. Splenocytes (5 × 105) from C57BL/6 mice were cultured in medium alone (Iscove’s supplemented with 10% heat-inactivated fetal bovine serum (FBS), sodium pyruvate, non-essential amino acid, 50 µM 2-mercaptoethanol (ME), 2 mM l-glutamine and 10 mM HEPES), medium containing 0·03125 µg/ml highly purified SEB (Toxin Technology Inc.

[2] In cooperation with signals from T-cell receptors, the receptors for IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21, which are members

of the common γ chain cytokine receptor family, provide pro-survival signals involving PI3K-Akt pathways in naive T lymphocytes.[34, 35] Furthermore, www.selleckchem.com/HIF.html Akt has been reported to modulate the activity of Stat3 and potentiate the expression of molecules acting downstream of Stat3.[36, 37] This suggests that various cytokines that activate the PI3K-Akt signalling pathway may confer resistance against apoptosis on resting T cells by promoting Stat3 activation, thereby enhancing Bcl-2 and Bcl-xL expression. In conclusion, our results suggest a role for Stat3 in the maintenance of naive T-cell homeostasis. Although we describe an important mechanism by which the T-cell pool is preserved under C646 manufacturer resting conditions, further studies should address whether Stat3 can provide survival signals to relatively quiescent T or B lymphocytes, such as memory T cells.

“Dying cells release genomic DNA into the surroundings Methocarbamol where the DNA is first degraded to oligodeoxynucleotides,

then to nucleotides, nucleosides and so on. Given that the unmethylated CpG dinucleotide (CpG motif), which is characteristic of bacterial DNA, is also contained in mammalian DNA and has been reported to be involved in the exacerbation of DNA-associated autoimmune diseases, we investigated whether nucleotides and nucleosides affect immune responses to phosphodiester (PO)-CpG DNA. Addition of non-CpG DNA to RAW264.7, murine macrophage-like cells, induced no significant TNF-α production irrespective of treatment with DNase I; however, DNase I-treated, but not untreated, non-CpG DNA increased the PO-CpG DNA-mediated TNF-α production. This increase was not observed with phosphorothioate-CpG DNA or ligands for TLR3, TLR4 or TLR7.

18 A STAT-5 phosphorylation assay was used to gauge IL-7 responsiveness in CD4+ and CD8+ cells. The increase of the percentage of P-STAT-5 cells, and an example of constitutive P-STAT-5 and IL-7-induced P-STAT-5, in HD and NHP are shown in Fig. 5(a,b). In NHPs, (n = 15) 84·4 ± 10·8% and 60·6 ± 12% of CD4+ and CD8+ cells showed an increase of P-STAT-5 cells in response to IL-7 stimulation. Similar numbers were obtained in PBMCs from HDs (n = 10): 87·6 ± 7·6% and 62·3 ± 15·4% in CD4+ and Kinase Inhibitor Library CD8+

cells, respectively. CD4+ and CD8+ subsets showed comparable responses to IL-7 stimulation as measured by STAT-5 phosphorylation in NHPs and HDs. In HDs and NHPs more CD4+ cells than CD8+ cells showed STAT-5 phosphorylation (consistent with higher levels of IL-7Rα expression on CD4+ T cells) but the amplitude (measured by MFI) was not statistically different between CD4+ and CD8+ cells. The presence of regulatory cells was assessed by expression analysis of CD25 and FoxP3 in the CD4+, CD8+ and CD4+ CD8+ T-cell compartments (gating strategy see Supplementary Fig. S2). In NHPs, the

CD4+ T-cell compartment showed the following frequencies: 16·5% (median values) were CD25intermediate (CD25interm.) and 0·5% stained for CD25bright; in CD4+ CD8+ T cells: 19·6% cells were CD25interm. and 1·4% were CD25bright; in CD8+ T cells: 1% were CD25interm. and 0·07% CD25bright (Table 2). Compared with HDs, higher frequencies of CD4+ CD25interm. T cells and CD4+ CD8+ CD25interm./bright,

and CD8+ CD25bright T cells (21%) were detected in PBMCs from NHPs. Analysis Atezolizumab mouse of FoxP3 expression in the different CD25+/− T-cell compartments showed that the majority of CD25bright T cells in NHPs were FoxP3+ (87·5% of CD4+ and 76% of CD4+ CD8+ and CD8+ T cells), whereas 3-mercaptopyruvate sulfurtransferase only 10–20% of CD25interm. T cells showed FoxP3 expression (Fig. 6a). In contrast, almost no FoxP3 expression could be observed in human CD4+ CD8+ CD8+ T cells that exhibited the CD25interm. phenotype. Analysis of PBMCs from four of eight HDs showed that CD4+ CD8+ and CD8+ T cells, which displayed a CD25bright phenotype, stained also positive for FoxP3. In summary, statistically higher frequencies (P ≤ 0·05) of CD4+/− CD25interm.FoxP3+/−, CD4± CD8± CD25interm./high FoxP3+/− and CD8± CD25interm./high FoxP3+/− were detected in NHPs than in HDs. Expression of the IL-7Rα on NHP CD25bright T cells was inversely correlated with expression of FoxP3, which is similar to the situation described in humans.25 More than 90% of NHP CD4+ CD8+ CD25interm./bright FoxP3+ T-cell subsets did not express the IL-7Rα, whereas the majority of CD4+ CD8+ CD25+/− FoxP3− (33–67%) were positive for IL-7Rα (% of IL-7Rα expression is shown for CD4+ T cells in Fig. 6b). The same trend was observed in HDs. However, 9% of human CD4+ CD25bright FoxP3+ T cells expressed the IL-7Rα (Fig. 6b), this was not true for the same T-cell subset in NHPs (3·8%).

(Shizuoka, Japan). Animals were given food and ultrafiltered water ad libitum, and were maintained on a 12-h/12-h light/dark cycle with lights on from 08:00 to 20:00 hours. The P. aeruginosa las quorum-sensing signal 3-oxo-C12-HSL was purchased from Sigma (St. Louis, MO). A stock solution of 10 mM 3-oxo-C12-HSL was prepared by dissolution in dimethyl sulfoxide (DMSO) and stored in a −20 °C freezer. Just before administration to the animals, the stock solution was diluted to 10 μM with 0.9% sodium chloride. A pure DMSO solution diluted with 0.9% sodium chloride was used in a similar manner as a control. For in vitro experiment for immunocytochemistry analysis, 100 mM 3-oxo-C12-HSL

stock solution was used. Full-thickness wounds were created in both lateroabdominal regions using sterile scissors under sedation with an intraperitoneal injection of Somnopentyl Crizotinib (pentobarbital sodium; Pexidartinib mouse Kyoritsu Seiyaku Corporation, Tokyo, Japan) (30 mg kg−1 body weight). The subcutaneous fat layer was completely dissected to expose the fascia. To investigate the effects of 3-oxo-C12-HSL on wound healing, we allowed granulation tissue to develop under moist conditions

using a transparent film dressing occlusion, and then challenged the granulation tissue with 3-oxo-C12-HSL on day 5 after wounding. Specifically, 100 μL of 10 μM 3-oxo-C12-HSL solution or control DMSO solution was administered to the surface of the granulation tissue using a micropipette.

This concentration was derived from the previous study, which demonstrated that the 10 μM 3-oxo-C12-HSL to the dermis could induce inflammatory cell infiltration and cyclooxygenase (Cox)-2 induction (Smith et al., 2002a). The wound was covered with transparent film dressing after the administration. The wound area was measured every day until 9 days after wounding using image analysis software (imagej version 1.42; NIH, Bethesda, MD) and expressed as relative values to the initial wound area (Pietramaggiori et al., 2008). The experimental protocol was approved by the Animal Research Committee of The University of Tokyo. All animals were treated according to the Guide for the Care and Use of Laboratory Animals of the NIH. Wound samples were Tyrosine-protein kinase BLK collected at 24 h after the 3-oxo-C12-HSL challenge. The collected samples were fixed in 4% paraformaldehyde in phosphate buffer, dehydrated with alcohol, cleared with xylene and processed for embedding in paraffin. Sections were prepared at 5-μm interval for hematoxylin and eosin (HE) staining. α-Smooth muscle actin immunostaining was performed as follows: the sections were incubated for 10 min with 3% H2O2 to quench the endogenous peroxidase activity. Between each set of the following steps, the sections were washed three times with phosphate-buffered saline (PBS) for 5 min each.

Moreover, both morphotypes should be examined by strain biotyping methods. Beta-N-hexosaminidase (HexNAcase) activity assessed by the api® ZYM test and on CHROMagar Candida® medium (Becton Dickinson, USA) is also discussed. “
“The mode of inhibitory action of Zataria multiflora Boiss. essential oil (EO) on the fungus, Aspergillus flavus, was studied by colony morphology examination, light microscopy, scanning electron

microscopy (SEM) and transmission electron microscopy (TEM). The EO at concentrations used in this study suppressed the size of the colony as well as sporulation. SEM of mycelia treated with given concentrations of EO showed morphological alterations ranging from loss of turgidity and uniformity of mycelia at low concentrations of EO to evident destruction of the hyphae at higher concentration of EO. Semi-thin selleck chemicals sections of mycelia exposed to different concentrations of EO were analysed by light microscopy and revealed that the major change at level as low as 50 ppm of EO was limited to vacuolisation of cytoplasm resulting in cell swelling, while at higher concentrations, detachment of the cell membrane from the cell wall, deformation of mycelia and shedding the cytoplasm from the cell were the main alterations. These damages were well documented by TEM, which showed that the main sites

of action of EO ABT-263 datasheet were the plasma membrane and cell wall. In conclusion, morphological and structural changes observed in this study may be one of the mechanisms involved in growth inhibition of the fungi and reducing aflatoxin Phloretin production. “
“Various studies have documented a shift in species distribution in Candida bloodstream infections (BSI), but there are little data from Southeast Asia. This study was performed to determine the species epidemiology and antifungal susceptibilities of Candida species BSI in Singapore. Candida spp. from BSI were collected from a tertiary and secondary referral hospital, and an obstetrics/paediatric hospital over a 3-year period. The most common isolates were Candida albicans (36%), Candida tropicalis (27%), Candida glabrata

(16%) and Candida parapsilosis (16%). Candida parapsilosis and C. albicans were predominant in the paediatric hospital, and C. albicans and C. tropicalis predominant in the other two institutions. Candida tropicalis temporarily replaced C. albicans as the predominant strain from BSI in 2006. Overall, 87.3% of Candida isolates were susceptible to fluconazole, and 10.4% classified as susceptible-dose-dependent. Fluconazole resistance was detected in C. tropicalis (3.6%), C. parapsilosis (2.1%) and C. glabrata (4.0%). Candida albicans is the predominant species isolated from BSI in Singapore. However, non-albicans species accounted for nearly two-thirds of all cases of candidaemia and the relative increase in C. tropicalis infections deserves further investigation.

Molecular epidemiological studies have shown that all major subtypes, including B, C, B’, BC and AE recombinant forms, exist in China, and recombinant subtypes are more prevalent [17]. In this study, we analysed the neutralizing activities of 80 serum samples derived from Chinese HIV-1 patients against a panel of HIV-1 clinical isolates and identified 8 cross-clade neutralizing sera (CNsera). We conducted further immunological characterization of the 8 CNsera to investigate the epitope specificities of the serum antibodies and the relationships to the cross-clade neutralization activity. The study shed light on the basic immunological

properties of the antibodies induced by infections of diverse viral isolates and the epitopes that mediate the cross-clade neutralizing find more activities. Sera were provided by Beijing YouAn Hospital. All sera were collected from Chinese individuals infected with HIV-1 through injection drug use, sexual intercourse or commercial blood donation after informed consent was obtained. This study was approved by the institutional review board at the YouAn Hospital and Nanjing University. GHOST(3)X4/R5, 293T cell line, PNL4-3 LucR−E− and Env-expressing plasmids were kindly provided by Prof. Linqi Zhang of Comprehensive AIDS Research Center, at Tsinghua University. Mutant

Env plasmids CNE6N160K and CNE55N160K were generated using the QuickChange mutagenesis kit (Stratagene, La Jolla, CA, USA). DMEM (high glucose), Opti-MEM, trypsin and fetal bovine serum were purchased from Gibco Biotechnology Inc. (Rockville, Y-27632 2HCl MD, USA). All peptides were Selumetinib order synthesized by GL Biochem Ltd. (Shanghai, China), and the sequences were shown in Table 1. Monoclonal antibodies (mAbs) b12, 2G12, 2F5, 4E10 and 447-52D were purchased from POLYMUN Scientific Inc. (Klosterneuburg,

Austria). Gp120IIIB, gp120JRFL, gp120JRFLD368R, gp120BC and gp120AE were purchased from HaiYuan Inc. (Taizhou, China). Mammalian cell codon-optimized V1V2BAL DNA sequences were synthesized by Invitrogen Inc. (Shanghai, China) and inserted into pTriEx-3 Hygro expression vector. V1V2BAL protein was expressed by transfecting Freestyle 293 (293F) cells in serum-free medium (Invitrogen, Carlsbad, CA, USA). Briefly, codon-optimized expression plasmid was transfected into 293F cells using PEI (Polysciences, Eppelheim, Germany) when the density of 293F cells reached 1.0 × 106/ml. The final concentrations of the plasmid and PEI were 1 μg/ml and 2 μg/ml, respectively. Supernatants were collected 6 days after transfection and concentrated using labscale tangential flow filtration cassette and system (Millipore, Billerica, MA, USA). V1V2BAL protein was purified by SwellGel Nickel-chelated discs (Pierce, Rockford, IL, USA), according to the manufacturer’s instructions.

burnetii genome in multiple copies has ensured detection of the bacteria. Designed PCR provided evidence of two C. burnetii-positive serum samples, no. 37 from Zemné and no. 47 from Vinice. Although in the course of testing we ended up with several unreadable results, all positive samples were reliably and repeatedly detected, and underwent PCR detection in duplicate.

Non-bacteria-positive, for example non-rickettsial, non-template controls, gave negative results in all runs performed. Furthermore, the clinical picture of the patients (A. Nyitray, unpublished data) endorses our results. Regardless of the applied method, we did not detect any case of Rickettsia mongolotimonae infection, which is known to cause lymphangitis-associated MAPK Inhibitor Library rickettsiosis (Fournier et al., 2005), nor did we find Rickettsia felis. However, reports of human infection with R. felis are CP-673451 manufacturer rare (Renvoise et al., 2009). Similarly, some of Bartonella species used in this study remain undetected, for example Ba. henselae (Marseille), Bartonella alsatica, Bartonella vinsonii ssp. berkhoffii, Bartonella ‘weissi’, and Ba. vinsonii ssp. Arupensis. No infection

with human granulocytic ehrlichiosis (HGE) Anaplasma, or D. massiliensis was confirmed either. The use of two complementary methods, IFA and PCR, allowed us to show Rickettsia, Borrelia, Bartonella, Coxiella and Franciscella as possible sources of human infections in Slovakia. Not all serologically detected cases could be confirmed with PCR (Table 3). We are aware of certain limits of the PCR with a single template assay, as the number of organisms found in the

blood can be quite low. Detection limits for amplification of 47-kDa gltA and ompB gene targets of certain rickettsial strains are known be 2, 1 and 1 μL−1 in single template format, respectively (Paris et al., 2008). As few as seven copies of the 16S rRNA gene of R. helvetica could be detected in 200 μL of serum sample in another study (Choi et al., 2005). However, the use of two complementary tests, IFA and PCR, enabled the bacteria to be verified. Five of 16 rickettsial cases detected by IFA were confirmed by PCR. Rickettsiae have been detected in Slovakia previously (Rehacek et al., 1975; Kovacova et al., 2006), and R. slovaca (Sekeyova et al., 1998), R. helvetica (Spitalska et al., 2008) and R. raoultii (Boldis et al., 2008) Etomidate are ‘domestic’ and are frequently neglected by the local medical community. On the other hand, R. conorii serum reactivity in IFA (not confirmed with PCR) is questionable. This agent has never before been identified in Slovakia due to a missing corresponding tick vector (Rhipicephalus sanguineus). Rickettsiae need specific invertebrates as vectors or hosts (ticks, lice and fleas). Thus, together with other detected bacterial agents (Subramanian et al., 2011) they are probably one of the most important causes of systemic febrile illness in Europe (Parola & Raoult, 2001; Chmielewski et al.

2b). The colons, in addition, had significantly higher levels of the cytokines Csf2, Csf3, Il9 and Tnfa. The observed chemokine and inflammatory gene expression pattern was clearly reflected in the composition of the inflammatory infiltrates in the caeca and colons of the C. difficile-infected mice. Both organs contained significantly higher numbers of neutrophils after the infection (Fig. 3a), a finding consistent with the significant up-regulation of Cxcl1, Cxcl2 and Il17f. In addition, there was a substantial increase in CD11b expression on the recruited neutrophils

(Fig. 3b). Flow cytometric analysis showed a significant increase in the number of dendritic cells and cells of the monocyte/macrophage lineage in the caeca of the C. difficile-infected mice (Fig. 4a,b; compare with Supplementary material, Figure S3A and B); which was consistent with the increased expression levels of Ccl2. The infected colons showed a similar ACP-196 in vitro trend. A substantial fraction of the monocyte/macrophage lineage cells in the caeca and colons of the infected mice

expressed low levels of MHC II (Fig. 4c), which was consistent with their recent recruitment. The significant increase in the number MI-503 of lymphocytes (B cells, CD4 T cells and CD8 T cells) in the caeca and colons of the C. difficile-infected mice (Fig. 5a; compare with Supplementary material, Figure S4A) also correlated with the heightened expression of chemokines and pro-inflammatory genes. Nonetheless, the recruited CD4 T cells expressed levels of CD69 that were comparable with that found in their untreated counterparts (Fig. 5b; compare with Figure S4B) and had low levels of CD25 expression (assessed on CD4 T cells with gating to exclude the FoxP3+ subset) (Fig. 5c; compare with Figure S4C). These observations were in full biological concordance with the lack of any significant change in Tbx21, Gata3 or Rorc expression levels or in that of cytokines secreted by polarized T cells (data not diglyceride shown). There was a significant up-regulation of Il22 expression and

a number of anti-microbial peptides in the caeca and colons of the infected mice. These included Defa1, Defa28, Defb1 and Slpi in the colon and Reg3g in the caecum (Fig. 2c). There was also an increase in Reg3g levels in the colons of infected mice; however, in these experiments, the increase did not reach statistical significance. To assess the activation of the UPR in C. difficile infection in mice, caecal and colonic samples from untreated and C. difficile-infected mice were examined for their expression of numerous UPR markers. Immunoblotting showed a significant increase in the level of eIF2α phosphorylation, the most rapid aspect of the UPR, in the caeca and colons of the infected mice (Fig. 6a). This coincided with the significant up-regulation of Gadd34 and Wars mRNA expression levels, both downstream of eIF2α phosphorylation, in the infected samples (Fig. 6b).
