Surface glycoproteins found enriched on human M2 macrophages. SPEG analysis followed by LC-MS/MS identified five novel glycopeptides that are enriched on the surface of M2 macrophages (A). The red N (Asn) represents the site of N-linked glycosylation (A). Expression of enriched glycoproteins found on M2 macrophages was measured using immunoblotting (B). Integrin α3 (ITGα3), macrophage mannose receptor (CD206), cathepsin L, NHE, and legumain have increased expression relative to M1 macrophages (B).
