Title
Immunology: Killer fat.
Abstract
The article cites a study which found that lipid droplets in a type of immune cell may have a role in triggering attacks on infected damaged cells. It investigated that dendritic cells engulf pathogens, chop up their components and display the resulting antigens on their surfaces using the major histocompatability complex class I (MHCI) molecules. It noted that these antigens activate cytotoxic T cells, which find and destroy infected cells.
