Intestinal bacteria metabolite promotes capture of antigens by dendritic cells

Dendritic cells are immune cells that capture and present antigens to T cells, activating an immune response. Researchers have discovered that short-chain fatty acids produced by intestinal bacteria regulate a crucial step in this process, the extension of dendritic 'arms.' This breakthrough finding could potentially lead to the development of disease prevention strategies involving beneficial bacteria and new drugs targeting the regulation of dendritic cell function.
