Project description:Morphine causes microbial dysbiosis. In this study we focused on restoration of native microbiota in morphine treated mice and looked at the extent of restoration and immunological consequences of this restoration. Fecal transplant has been successfully used clinically, especially for treating C. difficile infection2528. With our expanding knowledge of the central role of microbiome in maintenance of host immune homeostasis17, fecal transplant is gaining importance as a therapy for indications resulting from microbial dysbiosis. There is a major difference between fecal transplant being used for the treatment of C. difficile infection and the conditions described in our studies. The former strategy is based on the argument that microbial dysbiosis caused by disproportionate overgrowth of a pathobiont can be out-competed by re-introducing the missing flora by way of a normal microbiome transplant. This strategy is independent of host factors and systemic effects on the microbial composition. Here, we show that microbial dysbiosis caused due to morphine can be reversed by transplantation of microbiota from the placebo-treated animals.

Project description:Investigating alterations the intestinal microbiome in a diet induced obesity (DIO) rat model after fecal transplant from rats, which underwent Roux-Y-Gastric-Bypass surgery (RYGB). The microbiomes of the RYGB-donor rats, the DIO rats, and DIO rats after receiving the fecal transplant from the RYGB rats. As controls lean rats as well as lean, RYGB and DIO rats after antibiotics treatment were used.

Project description:Lung tissues were collected from patients with IPF undergoing lung transplantation. Non-transplanted donor lung tissue showing no evidence of interstitial lung disease served as healthy controls. Septa from different regions of the lungs were mircodissected and their RNA was subjected to microarray-analysis. RNA from 10 heathy donor tissues was pooled and used as a pooled reference. From each of the 10 IPF patients, samples were collected once from “healthy looking” (non-fibrotic) regions and from fibrotic loci.

Project description:The frequency of delayed function of kidney transplants varies greatly and is associated with the quality of graft, donor age, and the duration of cold ischemia time. Body weight differences between donor and recipient can affect primary graft function. The underlying mechanism is poorly understood. Here, we have transplanted kidney grafts from commensurate body weight (L-WD) or reduced body weight (H-WD) donor rats into syngeneic or allogeneic recipients. 24 hours post-transplantation, serum creatinine level in H-WD recipients was significantly higher compared to that of L-WD recipients indicating impaired primary graft function. We detected a 10 fold higher transcription of IL-6 and dramatically increased tubular destruction in grafts from H-WD recipients. This was accompanied by decreased expression of genes associated with kidney function and an up-regulation of other genes such as cytochrome P450 isoforms, FosL and Trib3 as revealed by DNA microarray analysis. A single application of IL-6 into L-WD recipients is sufficient to impair primary graft function and to cause tubular damage. Whereas, immediate neutralization of IL-6 receptor signaling rescued primary graft function resulting in low serum creatinine levels, well-preserved kidney graft architecture and a normalized gene expression profile. These findings have strong clinical implication as anti-IL6R treatment of patients receiving grafts from lower-weight donors could be used to improve primary graft function. The dataset comprises eight samples divided into four sample groups. Each group represents rat kidneys collected after allogeneic transplantation under a certain condition and includes two biological replicates. The first group is characterized by a high body weight difference between donor and recipient, rats in the second group exhibit a low weight difference. Group three and four are similar to group one, but underwent an additional treatment with anti-IL6R mAb or prednisolone immediately after transplantation.

Project description:Bacillus licheniformis-fermented products (BLFP) are probiotics with antibacterial, antiviral, and anti-inflammatory properties that can improve growth performance. This study aimed to, firstly, compare the fecal microbiota of cats with chronic diarrhea (n = 8) with that of healthy cats (n = 4) from the same household using next-generation sequencing and, secondly, evaluate the effectiveness of oral administration of BLFP in relieving clinical signs and altering the intestinal microbiota in diarrheal cats. Six out of eight cats with diarrhea showed clinical improvement after BLFP administration for 7 days, and in two cats the stool condition was normal. A higher Firmicutes/Bacteroidetes ratio was noted in the feces of diarrheal cats without clinical improvement as compared with those in the healthy control group and in the diarrheal cats with clinical improvement after receiving BLFP. The phylum Bacteroidetes and class Bacteroidia decreased significantly in diarrheal cats regardless of BLFP administration. Blautia spp., Ruminococcus torques, and Ruminococcus gnavus, which belong to the Clostridium cluster XIVa and have been reported as beneficial to intestinal health, increased significantly in feces after BLFP treatment. Furthermore, a significant decrease in Clostridium perfringens was noted in diarrheal cats after BLFP administration. Overall, BLFP could be a potential probiotic to relieve gastrointestinal symptoms and improve fecal microbiota in cats with chronic diarrhea.

Project description:<p>Fecal microbiota transplantation (FMT) represents a potential strategy to overcome resistance to immune checkpoint inhibitors in patients with refractory melanoma; however, the role of FMT in first-line treatment settings has not been evaluated. We conducted a multicenter phase I trial combining healthy donor FMT with the PD-1 inhibitors nivolumab or pembrolizumab in 20 previously untreated patients with advanced melanoma. The primary end point was safety. No grade 3 adverse events were reported from FMT alone. Five patients (25%) experienced grade 3 immune-related adverse events from combination therapy. Key secondary end points were objective response rate, changes in gut microbiome composition and systemic immune and metabolomics analyses. The objective response rate was 65% (13 of 20), including four (20%) complete responses. Longitudinal microbiome profiling revealed that all patients engrafted strains from their respective donors; however, the acquired similarity between donor and patient microbiomes only increased over time in responders. Responders experienced an enrichment of immunogenic and a loss of deleterious bacteria following FMT. Avatar mouse models confirmed the role of healthy donor feces in increasing anti-PD-1 efficacy. Our results show that FMT from healthy donors is safe in the first-line setting and warrants further investigation in combination with immune checkpoint inhibitors.

Project description:Normothermic machine perfusion (NMP) after static cold storage is increasingly used for preservation and assessment of human donor livers prior to transplantation. Biliary viability assessment during NMP reduces the risk of post-transplant biliary complications. However, understanding molecular changes in the biliary system during NMP remains incomplete. Here, we performed RNA-seq analysis of donor livers undergoing NMP treatment and compared livers with biliary viability scores that were acceptable for transplantation vs those that were not.

Project description:<p>In this study, we investigated the role of the gut microbiota on the development of complications in kidney transplant recipients. We collected serial fecal specimens from 168 kidney transplant recipients within the first 3 months after transplantation. We performed 16S rRNA gene sequencing of the V4-V5 hypervariable region and examined whether the relative gut abundance of pathogenic bacteria was associated with future development of complications like bacteriuria and urinary tract infections. In a subset of samples, we performed metagenomic sequencing of stool and urine supernatant specimens to determine strain level analysis. </p>
