[Regulatory effect of exosome on cell apoptosis].

Exosome, a nano-grade biological membrane structure, is secreted by multiple cells, widely distributing in saliva, plasma, milk and other body fluid. It can directly and indirectly take part in the biological information transcription between the receptor cells and their micro-environment. Recent studies have demonstrated that exosomes play pivotal roles in the occurrence and development of viral infectious diseases, tumors and other cell apoptosis related diseases via regulating the apoptosis in various ways.
