Gut #microbiota composition during infancy and subsequent #behavioural outcomes
..The faecal microbiota were analysed at 1, 6, and 12 months of age. Behavioural outcomes were measured at 2 years of age.
Findings
In an unselected birth cohort, we found a clear association between decreased normalised abundance of Prevotella in faecal samples collected at 12 months of age and increased behavioural problems at 2 years, in particular Internalizing Problem scores. This association appeared independent of multiple potentially confounding variables, including maternal mental health. Recent exposure to antibiotics was the best predictor of decreased Prevotella.
Interpretation
Our findings demonstrate a strong association between the composition of the gut microbiota in infancy and subsequent behavioural outcomes; and support the importance of responsible use of antibiotics during early life.

The intestinal #microbiota and #cardiovascular disease
https://2medical.news/2020/03/06/the-intestinal-microbiota-and-cardiovascular-disease/
The intestinal microbiota of human hosts is the community of microorganisms living in the small and, mainly, the large intestine of humans. This microbial ecosystem has co-evolved with humans across the millennia, has come to play an important interactive role in human physiology and has been aptly called our forgotten organ. Significant properties of the microbiota benefiting its host include energy harvest from food sources …

Intratumoral accumulation of gut #microbiota facilitates CD47-based immunotherapy via STING signaling
https://2medical.news/2020/03/29/intratumoral-accumulation-of-gut-microbiota-facilitates-cd47-based-immunotherapy-via-sting-signaling/
..Using one defined anaerobic gut microbiota to track whether microbiota interact with host immunity, we observed that Bifidobacterium facilitates local anti-CD47 immunotherapy on tumor tissues through the capacity to accumulate within the tumor microenvironment. Systemic administration of Bifidobacterium leads to its accumulation within the tumor and converts the nonresponder mice into responders to anti-CD47 immunotherapy in a stimulator of interferon genes (STING)– and interferon-dependent fashion. …

Warmth Prevents #Bone Loss Through the Gut #Microbiota
https://2medical.news/2020/09/16/warmth-prevents-bone-loss-through-the-gut-microbiota/
Osteoporosis is the most prevalent metabolic bone disease, characterized by low bone mass and microarchitectural deterioration. Here, we show that warmth exposure (34°C) protects against ovariectomy-induced bone loss by increasing trabecular bone volume, connectivity density, and thickness, leading to improved biomechanical bone strength in adult female, as well as in young male mice. Transplantation of the warm-adapted microbiota phenocopies the warmth-induced bone effects. Both warmth …
