Target Background

Membrane glycoproteins implicated in the pathologic deposition of cholesterol in arterial walls during atherogenesis. Two types of receptor subunits exist. These receptors mediate the endocytosis of a diverse group of macromolecules, including modified low density lipoproteins (LDL).
Gene References into Functions
  1. Custom-produced fluorescently labeled versions of MOG or MDA-modified MOG was used to study and quantify the uptake by different macrophage populations (especially anti-inflammatory M2-type macrophages) and to identify the responsible receptor, namely SRA. The SRA-mediated uptake of MDA-modified MOG is roughly tenfold more efficient compared to that of the native form. PMID: 28828577
  2. TMP upregulated the protein stability of ABCA1 without affecting ABCG1. Accordingly, TMP regulated the expression of SR-A, CD36, ABCA1 and ABCG1 in aortas of ApoE-/- mice, which resembled the findings observed in macrophages. PMID: 28791414
  3. LPS may increase Ac-LDL uptake and enhance CD204 expression through MAPK/ERK activation in bone marrow-derived macrophages. PMID: 29032172
  4. The low magnitude of opsonin-independent phagocytosis of Escherichia coli and unimpaired phagocytosis of Staphylococcus aureus in SR-A- or CD36-deficient macrophages indicate that the defect in this process might not be responsible for the reported impaired bacteria clearance in mice deficient in these receptors. PMID: 27826145
  5. Data (including data from studies conducted in cells from knockout mice) suggest that signaling via Lpar1, Cd14, and Scara1 mediates uptake of oxidized LDL by macrophages leading to foam cell formation; lysophosphatidic acid (LPA) induces expression of Cd14 and Scara1 in macrophages. (Lpar1 = LPA receptor 1; Cd14 = monocyte differentiation antigen CD14; Scara1 = scavenger receptor class A type I) PMID: 28705936
