Strongyloides stercoralis infection reduces Fusicatenibacter and Anaerostipes in the gu t and increases bacterial amino-acid metabolism in early-stage chronic kidney disease

Project description:Understanding gut bacterial composition and proteome changes in patients with early-stage chronic kidney disease (CKD) could lead to better methods of controlling the disease progression. Here, we investigated the gut microbiome and microbial functions in patients with S. stercoralis infection (strongyloidiasis) and early-stage CKD.

Strongyloides stercoralis infection reduces bacteria producing short-chain fatty acids and increases bacterial amino-acid biosynthesis in early CKD patients

Project description:Controlling the progression of chronic kidney disease (CKD) at an early stage is critical for reducing disease severity. A cross-sectional study of chronic kidney disease (CKD) patients at all stages with S. stercoralis infection found that helminth infection caused gut dysbiosis, which may be involved in CKD progression. Because of the variation of gut microbiome results with helminth infection, the cross-sectional study of 16S rRNA sequencing, therefore, is insufficient to draw valid conclusions and correct the effects of S. stercoralis on the early stages of CKD. Combination with other omics approach is warrant to be better understand the disease.

Opisthorchis viverrini infection exacerbates kidney disease through gut dysbiosis and alteration of host proteome in nonalcoholic steatohepatitis hamsters

Project description:Non–alcoholic fatty liver disease (NAFLD) is high prevalent in worldwide and associated with chronic kidney disease (CKD). Infection with Opisthorchis viverrini (Ov) infection and consumption of high fat and high fructose (HFF) exacerbates NAFLD to nonalcoholic steatohepatitis in hamsters. Here, we aimed to investigate the effect a combination of HFF diet and Ov infection on kidney pathology via alteration of gut microbiome and proteome in hamster.

Investigation of Resistant Starch effect on gut microbiome in 5/6 nephrectomy mouse model of Chronic Kidney Disease

Project description:Background. Resistant Starch (RS) improves CKD outcomes. In this report we study how RS modulates host-microbiome interactions in CKD by measuring changes in abundance of proteins and bacteria in the gut. In addition, we demonstrate RS-mediated reduction in CKD-induced kidney damage. Methods. Eight mice underwent 5/6 nephrectomy to induce CKD and 8 served as healthy controls. CKD and Healthy (H) groups were further split into those receiving RS (CKDRS, n=4; HRS, n=4) and those on normal diet (CKD, n=4, H, n=4). Kidney injury was evaluated by measuring BUN/creatinine and by most-mortem histopathological evaluation. Cecal contents were analyzed mass spectrometry-based metaproteomics. PEAKS Studio was used to identify peptides via de novo sequencing. A set of R/Bioconductor packages and in house written scripts was further used to infer bacteria present, to evaluate changes in proteins and bacterial abundances, and to perform statistical analysis and hierarchical clustering. Results. The 5/6 nephrectomy compromised kidney function as seen by an increase in creatinine and BUN. Representative photomicrographs of trichrome-stained kidney sections showed reduced tubulointerstitial injury in CKD mice fed HAM-RS2 diet comparing to CKD mice fed normal diet. Identified organisms and proteins point toward a higher population of butyrate-producing bacteria, and reduced abundance of mucin-degrading bacteria. Conclusion. Resistant starch slows the progression of chronic kidney disease. Gut barrier function through maintenance of the mucin barrier plays a role in RS-associated improvements in CKD phenotype. Resistant starch supplementation leads to the active bacterial proliferation and the reduction of harmful bacterial metabolites.

Identification of urinary exosomal non-coding RNAs as novel biomarkers in chronic kidney disease

Project description:We aimed to identify urinary exosomal ncRNAs as novel biomarkers for diagnosis of Chronic Kidney Disease (CKD) for this, we examined 15 exosomal ncRNA profiles in urine samples from CKD patients from four different stages (I, II, III and IV) and compared them to 10 healthy controls. We identified a significant number of novel, differentially expressed ncRNAs in CKD patients compared to healthy, which might be employed as early diagnostic markers in CKD in the future.

Gut microbiome–gut host proteome reveals the impact of Microcystin-LR on kidney disease progression though gut–kidney axis

Project description:The gut-kidney axis plays a critical role in the progression of kidney disease through the interplay of gut microbiome and host proteome. This study examines the impact of microcystin-LR (MC-LR), a potent cyanotoxin, on kidney disease progression through alterations in the gut microbiome and host proteome.

Ultra-Processed Foods drive Intestinal Barrier permeability increasing Microvascular Disease risk

Project description:Abstract: Our intake of ultra-processed foods has dramatically increased over the past few decades in line with the prevalence of obesity and diabetes, key risk factors for microvascular diseases such as chronic kidney disease (CKD). The extent to which long-term intake of highly processed food influences CKD outcome is unclear. Here, we show in rodent models that a highly processed diet drives intestinal barrier permeability and an increased risk of CKD. Inhibition of the advanced glycation pathway, which generates Maillard reaction products within foods upon thermal processing, reversed kidney injury. Consequently, a highly processed diet leads to innate immune complement activation and local kidney inflammation via the potent proinflammatory effector molecule complement 5a (C5a). C5a receptor inhibition ameliorated albuminuria. In a mouse model of diabetes, a high resistant starch fiber diet led to a redistribution of the gut commensal consortium, prevented impaired gut barrier function and decreased the severity of kidney injury via suppression of complement. These results provide mechanistic insight into the role of highly processed foods on inflammation and chronic disease risk. One Sentence Summary: Ultra-processed diets promote chronic kidney disease

Gut-Derived Metabolite Trimethylamine N-Oxide Promotes Inflammation and Fibrosis Following Ischemia/Reperfusion through CCR2-Mediated Macrophage Infiltration

Project description:Inflammation plays a crucial role in the development of acute kidney injury (AKI) and subsequent chronic kidney disease (CKD) following renal ischemia-reperfusion (IR). It has been demonstrated that metabolites from the gut microbiota can trigger inflammatory responses and modulate renal damage induced by IR. However, the exact driving factors and underlying mechanisms of this process remain unclear. Trimethylamine N-oxide (TMAO), a choline metabolite derived from the gut, has been observed to increase in AKI and CKD patients. Our study reveals that glycyrrhizic acid (GA) exacerbates IR-induced AKI and subsequent CKD through TMAO. To delve into the underlying mechanisms, we employed single-cell sequencing to construct a molecular map of kidney cells.

Oxalobacter formigenes colonization slows the progression of CKD and reduces cardiac remodeling in CKD

Project description:Accumulation of oxalate in patients with chronic kidney disease (CKD) is associated with CKD progression and an increased risk of cardiac death. Whether reducing oxalate slows CKD progression and prevents cardiovascular complications remains unexplored. We colonized Oxalobacter formigenes (Oxf), an oxalate-degrading microbiome, in the intestines of control and CKD mice fed with 1% hydroxyproline for 23 weeks. RNA-seq analysis of heart tissues of CKD mice reveals dysregulated expression of metabolic pathways and Oxf colonization reverses these changes. These findings demonstrate that oxalate accumulation plays a role not only in CKD progression but also in cardiovascular complications.
