Biological age

1 study
  1. Prevotella is associated with biological age in PWH on ART.

    “PWH on ART had higher abundance of specific pro-inflammatory bacterial genera, such as Catenibacterium and Prevotella. These bacteria significantly correlated with accelerated local and systemic biological aging.”

Hormone therapy responses varied with women’s microbiomes

In a six-month trial of 356 perimenopausal women, starting vaginal and gut microbial communities were linked to differences in hormone therapy responses.In a six-month trial of 356 perimenopausal women, starting vaginal and gut microbial communities were linked to differences in hormone therapy responses.

Gut microbe products helped metformin protect bone in mice

Experiments in mice with ovaries removed linked the drug’s bone benefits to short-chain fatty acids, small molecules made by gut bacteria.Experiments in mice with ovaries removed linked the drug’s bone benefits to short-chain fatty acids, small molecules made by gut bacteria.
