New details about Shigella's translocon may help develop effective strategy to block infection

Shigella, a bacterial pathogen that causes dysentery and is the leading cause of childhood diarrheal diseases, inserts a pore called a translocon into an infected person's intestinal cells and then injects bacterial proteins into the cells.

Researchers expand understanding of how T cells recognize infections or disease

T cells communicate with other cells in the body in search of infections or diseases. This crosstalk relies on specialized receptors known as T cell receptors that recognize foreign molecular fragments from an infection or cancer that are presented for detection by particular molecules called major histocompatibility complex (MHC) or MHC-like.
