ATP binding cassette transporter ABCA1 modulates the secretion of apolipoprotein E from human monocyte-derived macrophages.
Apolipoprotein E (apoE) produced by macrophages in the arterial wall protects against atherosclerosis, but the regulation of its secretion by these cells is poorly understood. Here we investigated the contribution of the adenosine triphosphate binding cassette transporters ABCA1 and ABC8 to the secretion of apoE from either primary human monocyte-derived macrophages (HMDM) or human THP1 macroph...
متن کاملLipoprotein lipase secretion by human monocyte-derived macrophages.
Human monocyte-derived macrophages in culture produced lipoprotein lipase. Although freshly isolated blood monocytes did not secrete much lipase activity, 1 d in culture was sufficient to trigger measureable enzyme production. During 3 wk in culture, maximal activity was attained after 7 d. At all times, the culture medium contained more enzyme activity than did a serum-heparin eluate or a dete...
متن کاملEplerenone promotes alternative activation in human monocyte-derived macrophages.
BACKGROUND In this study, we have analyzed the response of human monocyte-derived macrophages to mineralocorticoid axis modulators. METHODS Human monocyte-derived macrophages were incubated with aldosterone alone, eplerenone alone, and the combination of aldosterone and eplerenone. The analyzed variables were nitric oxide and reactive oxygen species production, and the gene and protein expres...
متن کاملP2X4 Receptor-Dependent Ca2+ Influx in Model Human Monocytes and Macrophages
Monocytes and macrophages express a repertoire of cell surface P2 receptors for adenosine 5'-triphosphate (ATP) a damage-associated molecular pattern molecule (DAMP), which are capable of raising cytoplasmic calcium when activated. This is achieved either through direct permeation (ionotropic P2X receptors) or by mobilizing intracellular calcium stores (metabotropic P2Y receptors). Here, a side...
متن کاملActivation of human alveolar macrophages via P2 receptors: coupling to intracellular Ca2+ increases and cytokine secretion.
Alveolar macrophages play a crucial role in the pathogenesis of inflammatory airway diseases. By the generation and release of different inflammatory mediators they contribute to both recruitment of different leukocytes into the lung and to airway remodeling. A potent stimulus for the release of inflammatory cytokines is ATP, which mediates its cellular effects through the interaction with diff...
