Chemical compound and disease context of Msr1

 

Biological context of Msr1

  • Whereas MARCO was involved in opsonin-independent phagocytosis in CpG-ODN-pretreated but not in IL-4-pretreated J774 cells, anti-SR-A Abs inhibited particle uptake in untreated and IL-4-pretreated but not in CpG-ODN-pretreated cells [9].
  • Our current results indicate and suggest a model for MSR ligands differentially modulating specific PK signal transduction pathways, which regulate atherogenesis-related inflammatory cytokines TNF and IL-1 [10].
  • Whereas blockage of lysyl residues on apoB-100 of oxLDL by lipid peroxidation products appears to be critical for recognition by the scavenger receptor class A (SR-A), modification of the lipid moiety has been suggested to be responsible for recognition by the scavenger class B receptor, CD36 [11].
  • Macrophages lacking JNK2 displayed suppressed foam cell formation caused by defective uptake and degradation of modified lipoproteins and showed increased amounts of the modified lipoprotein-binding and -internalizing scavenger receptor A (SR-A), whose phosphorylation was markedly decreased [2].
  • As evidence, FC loading by non-SRA mechanisms activates p38 and CHOP, but not apoptosis unless the SRA is engaged [12].
 

Anatomical context of Msr1

 

Associations of Msr1 with chemical compounds

  • These data show that alternative lipid uptake mechanisms may contribute to macrophage cholesterol ester accumulation in vivo and suggest that the roles of SR-A and CD36 as proatherosclerotic mediators of modified LDL uptake in vivo need to be reassessed [13].
  • Extensively oxidized LDL and LDL modified by exposure to fatty acid peroxidation products were efficient competitors for the uptake of labeled oxidized LDL by SR-AI/II-deficient Kupffer cells, while acetyl LDL and malondialdehyde-modified LDL were relatively poor competitors [16].
  • Following NB-DNJ treatment SR-A became Endo H-sensitive, consistent with inhibition of N-glycan processing [7].
  • Glycolaldehyde, a reactive intermediate for advanced glycation end products, plays an important role in the generation of an active ligand for the macrophage scavenger receptor [17].
  • When EDTA was added to chelate divalent cations, the SR-A mediated 90 and 95% of the macrophage adhesion without and with serum, respectively [18].

Other interactions of Msr1

  • In this study, Apoe-/- mice lacking SR-A or CD36, backcrossed into the C57BL/6 strain for 7 generations, were fed an atherogenic diet for 8 weeks [13].
  • Disparate regulation and function of the class A scavenger receptors SR-AI/II and MARCO [9].
  • After 4 or 12 weeks of a high-fat diet, the sizes of atherosclerotic lesions in MSR-A/LDLR double knockout mice were significantly reduced (p < 0.05) compared with those in LDLR single knockout mice [23].
  • It also suppressed expression of the 2 major scavenger receptors (scavenger receptor-A [SR-A] and CD36), in part by inhibiting IL-6, and inhibited macrophage foam cell formation [24].
  • The macrophage class A scavenger receptors, macrophage receptor with a collagenous structure (MARCO) and type I/II class A scavenger receptor (SR-AI/II), share structural features and roles in host defense, but little is known about their regulation and signaling properties [9].
