Shared Reference Notes
- [1.1]
- Reduced SCFAs levels, especially #Acetate, were associated with an increased risk of 90-day poor functional stroke outcomes even after adjustments. - [#Short Chain Fatty Acid] - A lack of SCFAs-producing bacteria and a low fecal SCFAs level defined dysbiosis in AIS patients, especially those with increased stroke severity. The SCFAs levels were negatively correlated with stroke severity and prognosis.
- [1.2]
- Stroke increases the permeability of intestinal barriers , alters bacterial composition of the gut, causing gut dysbiosis and promotes seeding of gut bacteria within the lung, spleen, and liver . Such peripheral effects might exert additional effects on the damaged brain, thus hindering recovery. - [1.3]
- Innate and adaptive immune system plays a pivotal role in the evolution of cerebral injury, by actively participating in brain damage development on the one hand, and in tissue repair on the other . - The most known metabolite classes derived from the gut microbiota with immunomodulatory effects are: 1) amino acids and their derivatives; 2) products of microbial fermentation: short-chain fatty acids (SCFA) and polyphenols; 3) secondary bile acids; and 4) trimethylamines - [1.4]

- [1.5]
- bacteria with capacity of butyrate production, #Lachnospiraceae and #Ruminococcaceae, were depleted in individuals at a high risk of stroke. Fecal butyrate concentrations also were low in these people - [1.6] [#Short Chain Fatty Acid]
- SCFAs could promote recovery after stroke by acting on microglia to inhibit their activation - [1.7] [#Clostridiaceae]
- family Clostridiaceae_1 was negatively correlated with stroke risk and ischemic stroke risk. - [1.8] [#Cerebral microbleeds (CMBs)]
- Cerebral microbleeds (CMBs) influence long-term prognoses of stroke patients. - #Streptococcus mutans, a major cariogenic bacterium that expresses the collagen-binding protein Cnm, induces cerebrovascular inflammation, impairing blood brain barrier integrity and causing cerebral bleeding.
