Regulatory T-cell immunity and its relevance to atherosclerosis.

Abstract

Atherosclerosis is a chronic inflammatory disease of the arterial wall where both innate and adaptive immune responses contribute to disease initiation and progression. Recent studies from several groups suggest that subtypes of T cells, called regulatory T cells, previously shown to maintain immunological tolerance, inhibit the development and progression of atherosclerosis. Here, we review the current knowledge on the regulatory T-cell response and the major cytokines involved in its modulation in the context of atherosclerosis.
