abstract：:Islets of Langerhans of all species harbor a small number of resident macrophages. 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...
