Gram-negative gut bacteria and Toll-like receptor 4 linked to stimulation of cerebral cavernous malformations, suppression of a single gene by the microbiota promotes T cell survival in mice, quorum sensing negatively regulates toxin production in insect-associated bacteria and may facilitate stable colonization.
