Background: Serpin B2

Serpin B2, also known as Plasminogen Activator Inhibitor 2 (PAI-2), is a 415 amino acid serine-type endopeptidase inhibitor with high expression in blood, vasculature and placenta. Its expression is upregulated in pregnancy and in activated monocytes/macrophages by a wide range of viral, bacterial and parasitic agents. Serpin B2 is upregulated in monocytes from HIV-1 infected patients, and is thought to modulate Th1/Th2 responses. Serpin B2/PAI-2 colocalizes with CHL1 and Vitronectin and mediates neurite outgrowth during post-natal brain development. Inhibition of uPA by SerpinB2 in tumors is associated with a favorable prognosis.
