Coriobacteriaceae ⇒ Collinsella {10000158}

Shared Reference Notes

• [1.1] 
  - Barley contains abundant soluble #Beta-glucan fibers - #Bifidobacterium, #Butyricicoccus, Collinsella, #Ruminococcus 2, and #Dialister were characteristic candidate bacterias of the group that consumed large amounts of barley. - The relationship between #Barley consumption and #Bifidobacterium remained after adjusting for disease and dietary habits, and that of #Butyricicoccus remained after adjusting for disease. - Network and cluster analyses revealed that #Barley consumption was directly correlated with #Bifidobacterium and #Butyricicoccus.
• [1.2] [#Inflamatory bowel disease, #Systemic anti-microbiota IgG] 
  - a modified high-throughput, culture-independent approach to quantify systemic IgG against gut commensal bacteria in human serum samples without the need for paired stool samples. - Using this approach, we highlight several commensal bacterial species that elicit elevated IgG responses in patients with inflammatory bowel disease (IBD) including taxa within the clades Collinsella, #Bifidobacterium, #Lachnospiraceae, and #Ruminococcaceae.
• [1.3] 
  - Collinsella is increased in patients with #Rheumatoid Arthritis and is associated with increased gut permeability.
• [1.4] [#Dementia with Lewy bodies (DLB), #Parkinson’s Disease] [#Short Chain Fatty Acid] 
  - short-chain fatty acids-producing genera were decreased in DLB. - #Ruminococcus torques and Collinsella were increased in DLB, which were not changed in PD. - high #Ruminococcus torques and high Collinsella, which presumably increase intestinal permeability, as well as low #Bifidobacterium, which are also observed in #Alzheimer’s disease, were predictive of DLB.
• [#Dementia with Lewy bodies (DLB)] - #Ruminococcus torques and Collinsella are also major #Secondary bile acids-producing bacteria, we quantified fecal bile acids and found that the production of #Ursodeoxycholic acid (UDCA) was high in DLB.
• [1.5] [#Alzheimer’s disease] 
  - The proinflammatory genus Collinsella, identified as a risk factor for AD, was positively correlated with the APOE rs429358 risk allele in both samples. - 20 gut microbiota genera were initially identified as genetically associated with AD case/control status. Of these 20, three genera (#Eubacterium fissicatena as a protective factor, Collinsella, and #Veillonella as a risk factor) were independently significant in the replication sample.
• [1.6] [#Bipolar disorder] 
  - patients with type II BD exhibit a greater abundance of Collinsella in comparison to those with type I.
• [1.7] [#Rheumatoid Arthritis] 
  - overabundance of #Prevotella copri in early RA patients - proliferation of the genus Collinsela and some #Lactobacillus species. - Three mechanisms by which microbiota may contribute to RA pathogenesis were proposed: inflammatory responses (#Prevotella copri and #Lactobacillus), molecular mimicry (#Prevotella copri) and loss of intestinal barrier integrity (Collinsella).
• [1.8] [#Gender] 
  - #Depression > Female patients have a characteristic increase in the phyla #Actinobacteria, male patients have reduced #Bacteroidetes and both genders display disrupted #Firmicutes homeostasis and elevated Collinsella spp. abundance
• [1.9] [#Obesity] [#Physical activity] 
  - In normal but not overweight participants, high PA duration showed greater relative abundance of commensal taxa such as #Actinobacteria and #Proteobacteria phyla, as well as Collinsella and #Prevotella genera.
• [#Alzheimer’s disease] - Increased proportions of #Odoribacter and #Barnesiella and decreased proportions of #Eubacterium , #Roseburia , #Lachnoclostridium and Collinsella were seen in elders with other #Dementia types than AD.
• [1.11] [#High fibre diet] 
  - #Cashew fiber promoted #Butyric acid-producing bacteria-related operational taxonomic units (OTUs; #Butyricimonas and Collinsella) at higher relative abundances.
• [1.12] [#Diabetes Type 2] 
  - genus Actinobacterium Collinsella was confirmed to be associated with #Alzheimer’s disease, as well as #Rheumatoid Arthritis, #Atherosclerosis, and type 2 diabetes.
• [1.13] [#Obesity] [#Collinsella aerofaciens] 
  - subjects with BMI values ≥25 kg/m2 have higher relative abundances of members of the Collinsella genus (e.g., Collinsella aerofaciens), and the #Veillonellaceae and #Lachnospiraceae families (e.g., genera #Dorea, #Lachnospira, #Coprococcus).
• [1.14] 
  - Collinsella is a hydrogen-reducing bacteria that could cross-feed with #Desulfovibrio.
• [#Diabetes Type 2] [#Low fibre Diet] - Enriched Collinsella was widely reported in low-fiber diets and metabolic diseases (e.g., type 2 diabetes)
• [#Parkinson’s Disease] - the genera #Akkermansia and #Oscillospiraceae UCG-005, which have been identified as prodromal PD RBD-enriched - bacteria (e.g., Collinsella and #Desulfovibrio) which were potentially related to PD pathogenesis were already increased in prodromal PD RBD patient
• [#Parkinson’s Disease] - In prodromal PD patients, the overall microbiota composition shifted closely to early PD, with depletion of #Butyrate-producing bacteria, and overabundance of pro-inflammatory Collinsella, #Desulfovibrio, and #Oscillospiraceae UCG-005.
• [#Parkinson’s Disease] - Collinsella was associated with a higher level of pro-inflammatory #IL-17A, > exacerbate neuroinflammation especially microglial activation in PD rodent model
• - #Rheumatoid Arthritis > Collinsella may lead to intestinal hyperpermeability by down-regulating the expression of epithelial tight junction
• [1.15] [#Ankylosing spondylitis, #Spondyloarthritis] 
  - Patients with SpA showed an enrichment of Collinsella, and several Lachnospiraceae ASVs - HLA-B27+ individuals displayed enriched #Faecalibacterium.
• [1.16] [#Fecal Microbiota Transplantation, #Immune checkpoint inhibitor] 
  - Comparison of pre- and post-FMT stool samples in Immune checkpoint inhibitors patients with complete responses showed significant increases in alpha diversity and increases in the abundances of Collinsella and #Bifidobacterium, which were depleted in FMT responders before FMT.
• [1.17] [#Carbohydrate diet] 
  - On a #Fructose-rich diet, mice lost beneficial bacteria such as #Prevotella, #Muribaculum, and #Bifidobacterium - These #Fructose-rich diet mice also showed an enrichment of #Desulfovibrio, Collinsella, #Olsenella, and #Bacteroides as well as increased frequency of immune cells with pro-inflammatory characteristics
• [1.18] [#Pancreatic Cancer] 
  - The microbial-related metabolite panel includes indoleacyrlic acid, an #Indole-derivative, and #TMAO. - #TMAO- and indoleacrylic-acid-producing #Bacteria include those in the phyla of #Bacillota, #Bacteroidota, #Actinomycetota, and Pseudomonadota. - #Bacillota species such as Cs and Er and Bacteriodota species including Bt and Pd have been shown to be increased in fecal samples of patients with PDAC compared with control subjects. - Relative abundances of fecal Collinsella aeofaciens, a species of #Actinomycetota, is associated with poor prognosis in PDAC.
• [1.19] [#Rheumatoid Arthritis] 
  - overabundance of #Prevotella copri in early RA and loss of intestinal barrier integrity (possibly caused by increased bacteria like Collinsella) may be responsible for the inflammatory response.
