Quantitative proteomic analysis of four subtypes of M2 macrophages

In this study, we used mass spectrometry and label-free quantification (LFQ) to characterize the global proteomics of polarized (M1, M2a, M2b, M2c, and M2d) and unpolarized (M0) phenotypes of macrophages from human THP-1 monocytes. The results described the biological functions of the four M2 macrophages subtypes and provided available references for identifying M2 macrophages or subtypes of M2 macrophages.
