Dendritic cells have been found to directly kill T cells lacking CD47, providing a new insight into the immune system's ability to distinguish self from non-self. This discovery has potential implications for cancer treatment and raises questions about the therapeutic application of this novel mechanism.
A small peptide produced in predatory nematodes' skin prevents them from eating their kin, while they feed on close relatives. The discovery reveals a self-recognition system in nematodes that discriminates between self and other organisms.
