Transcriptome analysis of wild-type and Csf2-/- bone marrow-derived macrophages during legionella pneumophila infection

ABSTRACT: Pathogens have evolved a wide range of strategies to allow survival and subsequently cause diseases in human, however, it’s still poorly understood how the immune system operates successfully to overcome pathogen-induced disturbance and enable robust immune responses against infection. The intracellular bacteria Legionella pneumophila has the ability to block host translation which causes global protein synthesis blockade in the target cells, but the host can still strongly evoke innate immune responses. We previously found that IL-1 signaling was critical for innate immunity during Legionella infection. Here, we further clarify that IL-1 signaling acts directly on alveolar epithelial cells, which potently drives granulocyte-macrophage colony-stimulating factor (GM-CSF) production by these cells, and importantly, GM-CSF signaling fundamentally promotes inflammatory immune responses in myeloid cells through cell-intrinsic transcriptional regulation via JAK2/STAT5 pathway. Our findings reveal that lung epithelial cells act as a key intermediator to facilitate communication between infected cells and bystander cells which is essential for antimicrobial defense.

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.

Dendritic cell-derived IL-2 promotes apoptosis of terminally mature cells via a novel autocrine signaling pathway

Project description:Dendritic cells (DCs) are crucial for sensing pathogens and triggering immune response. GM-CSF myeloid dendritic cells (GM-DCs) secrete several cytokines including IL-2 upon activation by pathogen associated molecular pattern (PAMP) ligands. DC IL-2 has been shown to be important for innate and adaptive immune responses, however its importance in DC physiology has never been demonstrated. This is due to ambiguity in expression of the CD122 subunit of the IL-2 trimeric receptor complex crucial for signaling. We show here that autocrine IL-2 signaling is functional in GM-DCs in early time window of stimulation with PAMPs. IL-2 signaling selectively activates the JAK/STAT5 pathway by assembling holo-receptor complexs at the cell surface. Autocrine IL-2 signaling inhibits survival of PAMP matured GM-DCs which is crucial for maintaining immune tolerance and preventing autoimmunity. Our findings suggest immune regulation by a novel autocrine signaling pathway that can potentially be exploited in DC immunotherapy. Microarray technology was used to understand the role of IL-2 signaling in DC. Microarray was performed to investigate the role of IL-2 signaling in DC physiology. Hence Wt or IL-2-/- BMDCs were either treated or not with curdlan for 6h and taken for microarray.

mRNA and long noncoding RNA expression microarrays in GM-CSF or GM-CSF+IL6-induced mouse MDSC

Project description:Myeloid-derived suppressor cells (MDSCs) have emerged as major regulators of immune responses in cancer and other pathological conditions. Multiple factors including cytokines, transcription factors and multiple signaling pathways are involved in MDSC differentiation. Cytokines such as granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin(IL-6) etc could in vitro mediate development of MDSCs.IL-6 with GM-CSF mediated MDSC not only had stronger suppressive function but also the dynamics of their suppressive function was different from GM-CSF alone mediated MDSCs.To found a new regulatory factor (s) in tumor and inflammatory environments, we compared GM-CSF and IL-6 mediated MDSCs with GM-CSF alone mediated MDSCs using lncRNA microarray and protein-coding mRNA microarrays.

Single cell immune profiling reveals a developmentally distinct CD4+ GM-CSF+ T cell lineage that induces GI tract GVHD

Project description:Gastrointestinal (GI) tract involvement is a major determinant for subsequent morbidity and mortality arising during graft versus host disease (GVHD). CD4+ T cells that produce GM-CSF have emerged as central mediators of inflammation in this tissue site as GM-CSF serves as a critical cytokine link between the adaptive and innate arms of the immune system. However, cellular heterogeneity within the CD4+ GM-CSF+ T cell population due to the concurrent production of other inflammatory cytokines has raised questions as to whether these cells have a common ontology or if there exists a unique CD4+ GM-CSF+ subset that differs from other defined T helper (TH) subtypes. Using single cell RNA sequencing analysis, we identified two CD4+ GM-CSF+ T cell populations that arose during GVHD and were distinguishable by the presence or absence of IFN-γ co-expression. CD4+ GM-CSF+ IFN-γ- T cells which emerged preferentially in the colon had a distinct transcriptional profile, employed unique gene regulatory networks, and possessed a non-overlapping TCR repertoire when compared to CD4+ GM-CSF+ IFN-γ+ T cells as well as all other transcriptionally defined CD4+ T cell populations in the colon. Functionally, this CD4+ GM-CSF+ T cell population contributed to pathological damage in the GI tract which was critically dependent upon signaling through the IL-7 receptor but was independent of type 1 interferon signaling. Thus, these studies help to unravel heterogeneity within CD4+ GM-CSF+ T cells that arise during GVHD and define a developmentally distinct colitogenic TH GM-CSF+ subset that mediates immunopathology.

Differentiation of human monocytes to macrophages in the presence of GM-CSF +/- forskolin (FSK)

Project description:Macrophages are central mediators of the innate immune system that can be differentiated from monocytes upon exposure to cytokines. While increased cyclic adenosine monophosphate (cAMP) levels inhibit many lipopolysaccharide (LPS) -elicited macrophage inflammatory responses, the effects of elevated cAMP on macrophage differentiation are not well understood. We have differentiated monocytes to macrophages in the presence of GM-CSF or GM-CSF + FSK to elevate cAMP levels and determine its effects on differentiation. Microarray analysis was performed separately on samples from 3 human donors: 3 control and 3 forskolin-treated samples.

Vaccine Therapy and GM-CSF in Treating Patients With CNS Lymphoma

Project description:RATIONALE: Vaccines made from a person’s cancer proteins may help the body build an effective immune response to kill cancer cells. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving vaccine therapy together with GM-CSF may make a stronger immune response and kill more cancer cells. PURPOSE: This phase II trial is studying the side effects and how well giving vaccine therapy together with GM-CSF works in treating patients with CNS lymphoma.
