Mast cells and autoimmunity

Mast cells (MCs) are major effector cells in allergic diseases. Recently, it has become evident that the contribution of MCs extends far beyond their accepted role in allergic disease, and that they play a more extensive role in a variety of non-allergic immune processes such as the innate immunity response. These cells have a key role in both the induction and elicitation of several autoimmune conditions. Targeting MC development, maturation or activation may be of value in future prevention and treatment of autoimmune conditions. (C) 2004 Elsevier B.V. All rights reserved.
