SIGNAL INTEGRATION AND TRANSCRIPTIONAL REGULATION OF THE INFLAMMATORY PROGRAM ASSOCIATED WITH THE GM-/M-CSF SIGNALING AXIS IN HUMAN MONOCYTES [EXPRESSION DATA SET]

ABSTRACT: In recent years, the M-CSF and GM-CSF cytokines have been identified as opposing regulators of the inflammatory program. However, the two cytokines are simultaneously present in the inflammatory milieu, and it is not clear how cells integrate these signals. In order to understand the regulatory networks associated with the GM/M-CSF signaling axis we analyzed DNA methylation in human monocytes. Our results indicate that GM-CSF induces activation of the inflammatory program and extensive DNA methylation changes, while M-CSF-polarized cells are in a less differentiated state. This inflammatory program is mediated via JAK2 associated with the GM-CSF receptor and the downstream ERK signaling. However, PI3K signaling is associated with a negative regulatory loop of the inflammatory program and M-CSF autocrine signaling in GM-CSF-polarized monocytes. Our findings describe the regulatory networks associated with the GM/M-CSF signaling axis and how they contribute to the establishment of the inflammatory program associated with monocyte activation.

Differential analysis of GM-CSF-induced inflammatory monocyte-derived cells (MCs) isolated from various organs

Project description:Elevated frequencies of GM-CSF-producing helper T (TH) cells are consistently found in multiple sclerosis (MS) patients and GM-CSF expression is a non-redundant feature of pathogenic TH cells in preclinical models of MS. GM-CSF activates an inflammatory signature in monocytes, and their progeny are the most abundant cellular infiltrate in acute MS lesions. To model deregulated GM-CSF levels, we generated a transgenic mouse line allowing the induction of GM-CSF expression in mature, peripheral TH cells. This antigen-independent GM-CSF release induced severe neurological deficits with almost 100% penetrance, accompanied by the infiltration of inflammatory monocyte-derived myeloid cells into the brain stem and spinal cord. Other organs did not show obvious signs for clinical pathology, despite also being infiltrated by inflammatory myeloid cells. We aim to unravel differences between organs, their responses and also the potential of tissue destruction by infiltrating cells by sequencing inflammatory myeloid cells isolate from the individual organs.

Effect of JAK inhibitors Upadacitinib or Baricitinib on gene expression during human monocyte-derived macrophage differentiation

Project description:Macrophage phenotypic and functional heterogeneity derives from tissue-specific transcriptional signatures shaped by the local microenvironment. GM-CSF drives the generation of human monocyte-derived macrophages with a potent pro-inflammatory activity upon stimulation. Janus Kinase (JAK) inhibitors are small molecules that reversibly inhibit JAK activity and their subsequent intracellular signaling and have become the treatment of choice for diseases with an inflammatory or immune basis. We explored the molecular impact of blocking GM-CSFR-JAK2-STAT5 axis with the Janus Kinase (JAK) inhibitors Upadacitinib or Baricitinib on the gene expression profile in GM-CSF-primed human monocyte derived macrophages.

NK cell-derived GM-CSF is critical for enhancing pathological arthritis

Project description:GM-CSF is involved in immune complex (IC)-mediated arthritis. However, little is known about what is the cellular source of GM-CSF and how it is regulated during IC-mediated inflammation. Using novel GM-CSF reporter mice, we show that NK cells produce GM-CSF during an IC-mediated model of inflammatory arthritis. NK cells promoted STIA in a GM-CSF-dependent manner, as deletion of NK cells and selective removal of GM-CSF production by NK cells abrogated disease. Furthermore, we show that myeloid cell activation by GM-CSF is restrained by induction of JAK/STAT checkpoint inhibitor cytokine-inducible SH2-containing protein, CIS. Myeloid cells from CIS-deficient mice had exaggerated responses to GM-CSF, and these mice develop exacerbated STIA. Our data suggest that tissue NK cells may amplify joint inflammation in arthritis via GM-CSF production and thus represent a novel target in IC-mediated pathology. Endogenous CIS provides a key brake on signaling through the GM-CSF receptor and strategies that boost its function may provide an alternative anti-inflammatory approach.

CIS deficiency intensifies GM-CSF signaling to polarize alternative activated macrophages

Project description:GM-CSF paradoxically possesses ability to differentiate both classically activated macrophages (MØs) with dominant proinflammatory function (M1-like MØs) and alternative activated MØs with strong immunosuppressive function (M2-like MØs). The intrinsic regulatory mechanism responsible for functional polarization of MØs under GM-CSF signalling remains elusive. Here we revealed that cytokine-inducible SH2-containing protein (CIS), induced by GM-CSF, is a key determinant in controlling MØ polarization. Compared to WT MØs, Cish-/- MØs gained characteristics of alternative activated MØs (M2 MØs), showing high expression of prototypic M2 markers Arginase 1, Tgm2 and YM-1; strong suppression of T cell proliferation; and low production of IL-12 and other proinflammatory cytokines¬¬. Differing from canonical IL-4/STAT6/IRF4 signaling axis of M2 induction, development of M2 MØ characteristics in Cish-/- MØs was associated with intensified STAT5 activation and consequent IRF8 downregulation. Attenuation of GM-CSF signalling via JAK inhibition and IRF8 rescue corrected certain functional defects in Cish-/- MØs. As CIS inhibition in NK and T cells promotes anti-tumour immunity, we showed that CIS deficiency enhanced the development of intra-tumoural M2 MØs and reduced CTL induction within tumour microenvironment with elevated GM-CSF. Overall, we conclude that CIS acts as an intrinsic rheostat to control intense GM-CSF signalling in order to maintain proinflammatory functions of MØs. Targeting CIS as a checkpoint in cancer immunotherapy should consider its role in regulating myeloid cell function.
