Lipid raft redox signaling: molecular mechanisms in health and disease.
Lipid rafts, the sphingolipid and cholesterol-enriched membrane microdomains, are able to form different membrane macrodomains or platforms upon stimulations, including redox signaling platforms, which serve as a critical signaling mechanism to mediate or regulate cellular activities or functions. In particular, this raft platform formation provides an important driving force for the assembling...
متن کاملLipid raft-redox signaling platforms in plasma membrane.
Membrane lipid rafts (LRs) have been demonstrated to be importantly involved in transmembrane signaling in a variety of mammalian cells. Many receptors can be aggregated within the LR clusters to form signaling platforms. Currently, LRs were reported to be clustered to aggregate, recruit, and assemble NADPH oxidase subunits and related proteins in various cells in response to various stimuli, f...
متن کاملLipid raft redox signaling platforms in endothelial dysfunction.
In response to various stimuli, membrane lipid rafts (LRs) are clustered to aggregate or recruit NADPH oxidase subunits and related proteins in vascular endothelial cells (ECs), forming redox signaling platforms. These LR signaling platforms may play important roles in the normal regulation of endothelial function and in the development of endothelial dysfunction or injury under pathological co...
متن کاملLipid Raft in Cardiac Health and Disease
Lipid rafts are sphingolipid and cholesterol rich micro-domains of the plasma membrane that coordinate and regulate varieties of signaling processes. Lipid rafts are also present in cardiac myocytes and are enriched in signaling molecules and ion channel regulatory proteins. Lipid rafts are receiving increasing attention as cellular organelles contributing to the pathogenesis of several structu...
متن کاملMechanisms of Redox Signaling in Cardiovascular Disease
Arrays of chemical oxidants are produced in healthy cells, where they function as important signaling molecules that are crucial in homeostatic regulation and cellular adaptation. The molecular basis of “redox signaling” is a series of oxido-reductive chemical reactions in which oxidants or reductants posttranslationally alter the structure of proteins. These modifications equate to signal sens...
