ONLINE COVER Foraging for Fatty Acids. This month's cover illustration depicts high fat content foods that are a source of fatty acids, one of the sources of metabolic fuel for T lymphocytes. During and following resolution of infection, some circulating memory T cells in the vasculature enter tissues and stay lodged in tissues as long-term residents. These sentinel T cells have been termed tissue-resident memory T (TRM) cells. Frizzell et al. compared the expression of fatty acid-binding proteins (FABPs) by TRM cells from different mouse organs and observed that the FABP profile of TRMs depends on where they are housed.
