Glycoproteomics of human THP-1-derived M0, M1 and M2 macrophages

In this study, we used human THP-1-derived macrophages as an immune cell model, and systematically performed glycoproteomics of three subtypes of macrophages by StrucGP.To study the N‑Glycoproteomic of them, the intact glycopeptides were first enriched and identified using triplicate mass spectrometry (MS)-based glycoproteomic approaches, then StrucGP was used for subsequent analysis. In total three subtypes of macrophages, these intact glycopeptides consist of 253 N-linked glycan structures at 652 unique glycosites from 372 N-glycoproteins, along with their PSM information. A total of 135, 163, and 201 N-glycan structures were identified from M0, M1, and M2 macrophages, respectively.
