Abstract We examined the presence of estrogen receptors (ER) in vascular mast cells and a possible genomic effect of estrogens on the expression of mast cell (MC) mediators such as chymase, TNFα, NOS and IL-10, which are known to affect the course of atherosclerosis. Immunocytochemical detection of mast cell tryptase and the co-localization of ERs in MCs from abdominal aortic vessels from 10 fertile woman, 10 postmenopausal women and 15 men was performed. The genomic expression of IL-10, TNFα, and NOS was analyzed by RT-PCR and chymase activity by spectrophotometry after 24 h incubation with 17-β estradiol (0.2-0.5 ng/mL) in rat… More >
