P16INK4a deficiency promotes IL-4-induced polarization and inhibits proinflammatory signaling in macrophages.

ABSTRACT: The CDKN2A locus, which contains the tumor suppressor gene p16(INK4a), is associated with an increased risk of age-related inflammatory diseases, such as cardiovascular disease and type 2 diabetes, in which macrophages play a crucial role. Monocytes can polarize toward classically (CAM?) or alternatively (AAM?) activated macrophages. However, the molecular mechanisms underlying the acquisition of these phenotypes are not well defined. Here, we show that p16(INK4a) deficiency (p16(-/-)) modulates the macrophage phenotype. Transcriptome analysis revealed that p16(-/-) BM-derived macrophages (BMDMs) exhibit a phenotype resembling IL-4-induced macrophage polarization. In line with this observation, p16(-/-) BMDMs displayed a decreased response to classically polarizing IFN? and LPS and an increased sensitivity to alternative polarization by IL-4. Furthermore, mice transplanted with p16(-/-) BM displayed higher hepatic AAM? marker expression levels on Schistosoma mansoni infection, an in vivo model of AAM? phenotype skewing. Surprisingly, p16(-/-) BMDMs did not display increased IL-4-induced STAT6 signaling, but decreased IFN?-induced STAT1 and lipopolysaccharide (LPS)-induced IKK?,? phosphorylation. This decrease correlated with decreased JAK2 phosphorylation and with higher levels of inhibitory acetylation of STAT1 and IKK?,?. These findings identify p16(INK4a) as a modulator of macrophage activation and polarization via the JAK2-STAT1 pathway with possible roles in inflammatory diseases.

The CDKN2A locus, which contains the tumor suppressor gene p16(INK4a), is associated with an increased risk of age-related inflammatory diseases, such as cardiovascular disease and type 2 diabetes, in which macrophages play a crucial role. Monocytes can polarize toward classically (CAMϕ) or alternatively (AAMϕ) activated macrophages. However, the molecular mechanisms underlying the acquisition of these phenotypes are not well defined.

Project description:The experiments were done using an Orbitrap Fusion or an Orbitrap Fusion Lumos mass spectrometer. Multiplexing was achieved using either TMT10 or TMT11 reagents and the SPS-MS3 method. Basic pH reversed-phase chromatography (bRPLC) was used for off-line pre-fractionation; 12 fractions were analyzed for proteome mappings (PMID: 26700037) and 24 fractions plus a phosphotyrosine-enriched sample for phosphoproteome mappings (PMID: 31606085). Phosphoproteome mappings were done using both HCD fragmentation with Orbitrap fragment ion detection and CID fragmentation with ion trap fragment ion detection (PMID: 29487189, PMID: 31606085). If multiple TMT sets were required to analyze all samples from an experiment two bridge channels pooled from all samples was used to connect the data from the individual TMT sets (PMID: 28892078). Five proteomics experiments are described in the paper: (i) 1.
