Abstract
An interesting C-type lectin-like receptor is LOX-1. LOX-1 is a membrane glycoprotein with a cytoplasmic domain, a transmembrane domain, and an oxidized low-density lipoprotein (oxLDL)-binding extracellular lectin-like domain. LOX-1 is involved in a variety of physiological and pathophysiological processes. The LOX-1 receptor is able to mediate the uptake of minimally and maximally oxidized LDL. In addition, LOX-1 plays a role in the phagocytosis of aged and apoptotic cells, the uptake of advanced glycation end products, thrombocyte adhesion, and the interaction between bacterial proteins and endothelial cells in sepsis. It is considered as a therapeutic target in atherosclerosis and cardiovascular disease. Recently, LOX-1 has been described in response to different danger signals, rheumatic diseases, preeclampsia, and bone diseases. This review focuses on the increasing evidence supporting a novel role of LOX-1 in immunity. LOX-1 and other pattern recognition receptors are expressed on the surface of myeloid cells like macrophages, dendritic cells, or neutrophils. They have an important role in the immediate innate immune response and also in the regulation of the adaptive immune response.
