The g/d T cells cannot present antigen or phagocytose pathogens, and they do have to be activated to become effector cells. However, they do not recognize specific antigen as other T cells do. The g/d TCR recognizes general features of microbes, including a group of phosphorylated molecules that are common to microbes, similar to the pathogen-associated microbial pattern (PAMP) recognition by phagocytes. The limited diversity of the receptors is a feature of the innate immune system rather than the adaptive immune system.
