Project description:Using the highly sensitive miRNA microarray, we screened 107 up-regulated microRNAs and 33 down-regulated microRNAs in the INT-HA-induced M2-like macrophages and we explored the functions of these miRNAs in macrophage polarization. The enrichment results indicated that these miRNAs might participate in the process of macrophage polarization. Furthermore, the quantitative real-time polymerase chain reaction results showed that miR-935 may play an important role in M2 macrophage polarization which was activated by INT-HA.

Project description:While naive BMDMs without further treatment are referred to as M0-like macrophages, which can be polarized to either M1-like or M2-like macrophages,To assess the consequence of PTEN binding on macrophages, we profiled the global transcriptome of M0-like BMDMs with and without PTEN treatment.

Project description: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.

Project description:The relative contribution of polarized macrophages to the maintenance of tolerance is unknown. We examined their roles by in vivo adoptive transfer immunotherapy of M0, M1 and M2a macrophages as pre-treatment of colitis. In other experiments, M2a macrophages were used as pre-treatment or treatment of established colitis followed by immunotherapy with nTreg cells. Survival, weight gain, tissue infiltration, iTreg and Th17 cell development, T cell activation, and the frequency of proinflammatory cytokines were used as outcome measurements. Pre-treatment with M2a but not M1 macrophages increased the development of iTreg and Th17 cells. M2a macrophages used as pre-treatment or in treatment of established colitis allowed for successful therapy with nTreg cells. M1 and M2a macrophages have distinct gene expression profiles. M0, M1 and M2a macrophages were cell sorted and were used to generate total RNA for each array set, which was labeled and hybridized to Affymetrix Mouse Genome 430 2.0 GeneChips in accordance to the manufacturerâ??s protocol. Three sets of arrays were performed, and the results were averaged. The subset of probe sets whose expression increased or decreased by two-fold or more relative to M0 cells as a common standard was identified and used for further analysis.

Project description:Ficolled AML-M0 sample gene expression profiles on Affymetrix HGU133Plus2.0 GeneChips. Acute myeloid leukemia (AML) classified as FAB-M0 is defined as a subtype with minimally differentiated morphology. Here we investigated by gene expression (GEP) profiling whether AML-M0 cases should be considered as one or more unique molecular subgroups that discriminates them from other AML patients. By applying GEP and subsequent unsupervised analysis of 35 AML-M0 samples and 253 previously reported AML cases, we demonstrate that AML-M0 cases express a unique signature. Hematological transcription regulators such as CEBPA, CEBPD, PU.1 and ETV6 and the differentiation associated gene MPO appeared strongly down-regulated, in line with the very primitive state of this type of leukemia. Moreover, AML M0 cases appeared to have a strong positive correlation with a previously defined immature AML subgroup with adverse prognosis. AML-M0 leukemias frequently carry loss-of-function RUNX-1 mutation and unsupervised analyses revealed a striking distinction between cases with and without mutations. RUNX1 mutant AML-M0 samples showed a distinct up-regulation of B-cell-related genes, e.g. members of the B-cell receptor complex, transcriptions regulators RUNX3, ETS2, IRF8 or PRDM1 and major histocompatibility complex class II genes. Importantly, expression of one single gene, i.e. BLNK, enabled prediction of RUNX1 mutations in AML-M0 with high accuracy. We propose that RUNX1 mutations in this subgroup of AML cause lineage infidelity, leading to aberrant co-expression of myeloid and B-lymphoid genes in the same cells.
