Psoriasis and atherosclerosis are diseases in which effector T lymphocytes such as Helper T cells type 1 (Th1) and 17 (Th17) play integral roles in disease pathogenesis and progression. Regulatory T cells (Treg) also exert clinically important anti-inflammatory effects that are pathologically altered in psoriasis and atherosclerosis. We review the immunological pathways involving Th1, Th17 and Treg cells that are common to psoriasis and atherosclerosis. These shared pathways provide the basis for mechanisms that may explain the epidemiologic observation that patients with psoriasis have an increased risk of heart disease. Improved understanding of these pathways will guide future experiments and may lead to the development of therapeutics that prevent or treat cardiovascular complications in patients with psoriasis.
