Multiple roles of connexins in atherosclerosis- and restenosis-induced vascular remodelling.
Endothelial dysfunction is the initial step in atherosclerotic plaque development in large- and medium-sized arteries. This progressive disease, which starts during childhood, is characterized by the accumulation of lipids, macrophages, neutrophils, T lymphocytes and smooth muscle cells in the intima of the vessels. Erosion and rupture of the atherosclerotic plaque may induce myocardial infarct...
متن کاملEffects of Losartan on expression of connexins at the early stage of atherosclerosis in rabbits
AIM to investigate effects of Losartan on expression of connexin 40 and 43 (Cx40 and Cx43), in arteries at the early stage of atherosclerosis in a rabbit model. METHODS A total of 28 male New Zealand white rabbits were divided into following groups: control group, high fat diet group, and Losartan group (10 mg/kg/day). Losartan was administrated in food for two weeks. Iliac arteries were obta...
متن کاملConnexins in the Nervous System
This chapter reviews the localizations and physiological roles of connexins in neurons and glia of the central and peripheral nervous systems. Cx32 forms gap junctions in noncompact myelin in Schwann cells, which are thought to form a reflexive communication pathway connecting the outer and inner myelin layers. Cx29 is also expressed in myelinating Schwann cells, but does not appear to form gap...
متن کاملConnexins in leukocytes: shuttling messages?
Gap junctions, formed by the connexin (Cx) protein family, are intercellular channels that permit the cytoplasmic exchange of ions and small metabolites between neighboring cells, a process called gap junction intercellular communication (GJIC). These channels possess unique properties, including distinctive permeabilities for various signaling molecules, which depend on the connexin member(s) ...
متن کاملWhich connexins connect?
Electrical signaling via gap junctions modulates vascular function via 2 physiologically interrelated mechanisms, namely dilations/constrictions that propagate longitudinally along the vessel wall,1–4 and the EDHF phenomenon, in which relaxation is facilitated by the transmission of endothelial hyperpolarization to smooth muscle via a radial myoendothelial pathway.5 Gap junctions are composed f...
