 exosomes are small vesicles released from cells when they fuse with the plasma membrane. These vesicles can be used as biomarkers for diseases and can also be used to study how cells communicate with each other. Recent studies have shown that these vesicles are released in response to calcium influx, which suggests that they could be involved in the repair of damaged plasma membranes. This research has found that a protein called Anshin A6 is necessary for this process, and it is thought that Anshin A6 helps to anchor the vesicles to the plasma membrane so that they can be released.
