Background

MARCO (macrophage receptor with collagenous structure), also known as SCARA2, is an 80 kDa type II transmembrane glycoprotein that belongs to the class A scavenger receptor family. MARCO is constitutively expressed on the surface of splenic and lymph node macrophages. Its expression is induced on Kupffer cells and alveolar macrophages by microbial infection, chemical irritants, and Th1 polarizing factors. MARCO binds LPS, lipoteichoic acid, and other determinants on Gram positive and negative bacteria. It also binds modified LDL, CpG oligonucleotides, UGRP1, silica, and TiO2. MARCO is required for the organization of the splenic marginal zone and the interaction of local macrophages and B cells.
