Evolution of the complement system.

abstract：:Cell death is an integral part of the functioning of the immune system. For T cells, potentially autoreactive or 'useless' cells are removed through apoptosis in response to signals (or lack of signals) from their T cell receptor complex. A myriad of proteins that can initiate or protect cells from cell death have rec...

These macrophages are found since birth, do not exchange with blood monocytes, and are maintained by a low level of replication. Under steady state conditions, the islet macrophages are in an activated state. Islet macrophages have an i...
