Role of bacterial polyclonal activators in autoimmunity

Abstract

Polyclonal activation of lymphocytes constitutes a non-specific stimulation resulting in the production and secretion by these cells of biologically active molecules, including antibodies. Polyclonal activation of human and animal lymphocytes can be observed, usually in vitro, with many active macromolecules of bacterial origin (surface constituants or excreted compounds). It is a complex phenomenon which may involve several cell populations (B-lymphocytes, T-lymphocytes, macrophages, etc.) and numerous mediators (lymphokines, monokines, etc.). An ever increasing collection of data suggests that polyclonal activators induce the synthesis of a variety of antibodies directed against the host (auto-antibodies). The relationship between auto-immune diseases and the presence of polyclonal activators in situ is discussed.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
