WebAug 23, 2024 · In this study, we investigated the expression patterns of MHC class II (MHCII) and associated molecules and find that the intermediate monocytes express the highest levels of the MHC molecules, HLA-DR (tested in n = 30 samples), HLA-DP (n = 30), and HLA-DQ (n = 10). WebWhen monocytes are differentiated into iDCs, they are expected to upregulate MHC class II molecules and CD1a at the same time, while losing CD14 molecules expression. 32 Upon maturation with LPS, iDCs upregulate costimulation molecules such as CD80 and CD86. 32 We observed that ASW induced significant changes in the phenotype of LPS-matured DCs. can a low temperature denature an enzyme
