Quantitative Proteome Responses to Oncolytic Reovirus in GM-CSF and M-CSF-Differentiated Bone Marrow-Derived Cells

ABSTRACT: To explore reovirus-macrophage interactions, we performed tandem mass tag (TMT)-based quantitative temporal proteomics on mouse bone marrow-derived macrophages (BMMs) generated with 2 cytokines, M-CSF and GM-CSF, representing anti- and pro-inflammatory macrophages, respectively. We quantified 6,863 proteins across five time points in duplicate, comparing M-CSF (M-BMM) and GM-CSF (GM-BMM) in response to OV. We find that GM-BMMs have lower expression of key intrinsic proteins that facilitate an anti-viral immune response, express higher levels of reovirus receptor protein JAM-A and are more susceptible to oncolytic reovirus infection compared to M-BMMs. Interestingly, although M-BMMs are less susceptible to reovirus infection and subsequent cell death, they initiate an anti-reovirus adaptive T cell immune response comparable to that of GM-BMMs. Taken together, these data describe distinct proteome differences between these two macrophage populations in terms of their ability to mount anti-viral immune responses.

Expression data of colony-stimulating factor (CSF) grown bone marrow derived cells

Project description:Granulocyte-Macrophage colony stimulating factor (GM-CSF) devlops heterogenous myeloid cell populations from bone marrow progenitor cells. In vitro generated bone marrow derived cells are excellent sources for obtaining dendritic cells or macrophages, but it is still not clear about the exact mixed population characteristics of GM-CSF grown cells. We revealed here that GM-CSF grown bone marrow cell derived attaching cells were composed of dendritic cells (GM-BMDC) as well as macrophages (GM-BMM). We compared the transcriptome profiles of these cell populations as well as M-CSF grown bone marrow derived macrophages (M-BMM). We used microarrays to detail the global profile of gene expressions between three populations of CSF-grown bone marrow derived cells: GM-CSF derived dendritic cells (GM-BMDC), GM-CSF derived macrophages (GM-BMM) and M-CSF derived macrophages (M-BMM). Bone marrow cells were differentiated for 7 days with 25 ng/ml GM-CSF or 20% L cell conditioned media as a M-CSF supplier. GM-BMDCs were sorted from MHCIIhighF4/80low population and GM-BMMs were sorted in the MHCIIlowF4/80high population. M-BMMs were sorted from CD11b+F4/80+ population.

Gene expression microarray data of bone marrow derived macrophages using GM-CSF(GM-BMMs) co-cultured with E0771 breast tumor cells

Project description:E-FABP is dominately expressed in macrophages/dendritic cells. Thus E-FABP may play a siginificant role in their immune response to tumor insult. We treated mouse GM-BMMs of different genotype with E0771 breast cancer cells. Then we investigate the global gene expression in these GM-BMMs in response to tumor treatment. Bone marrow cells were collected from naïve C57BL/6 and E-FABP knockout mice of 6~8 week old. GM-BMMs were derived using GM-CSF (in RPMI1640 with 5%FBS) for 7 days before tumor treatment. After 18hr tumor teatment, GM-BMM total RNA was extracted using RNeasy Mini Kit (Qiagen) and subjected to mouse mRNA Gene expression by Affymetrix microarray.

Proteomic analysis reveals distinct metabolic differences between GM-CSF and M-CSF grown macrophages derived from murine bone marrow cells

Project description:Macrophages are crucial in controlling infectious agents and tissue homeostasis. Macrophages require a wide range of functional capabilities in order to fulfill distinct roles in our body, one being rapid and robust immune responses. To gain insight into macrophage plasticity and the key regulatory protein networks governing their specific functions, we performed quantitative analyses of the proteome and phosphoproteome of murine primary GM-CSF and M-CSF grown bone marrow derived macrophages (GM-BMMs and M-BMMs, respectively) using the latest isobaric tag based tandem mass tag (TMT) labeling and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Strikingly, metabolic processes emerged as a major difference between these macrophages. Specifically, GM-BMMs show significant enrichment of proteins involving glycolysis, the mevalonate pathway, and nitrogen compound biosynthesis. This evidence of enhanced glycolytic capability in GM-BMMs is particularly significant regarding their pro-inflammatory responses, because increased production of cytokines upon LPS stimulation in GM-BMMs depends on their acute glycolytic capacity. In contrast, M-BMMs upregulate proteins involved in endocytosis, which correlates with a tendency toward homeostatic functions such as scavenging cellular debris. Together, our data describes a proteomic network that underlies the pro-inflammatory actions of GM-BMMs as well as the homeostatic functions of M-BMMs.

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.

M-CSF-responsive immortal macrophages are a new model for studying macrophage function

Project description:We generated non-senescent, macrophage colony stimulating factor (M-CSF) dependent macrophages from murine fetal livers. These fetal liver macrophages (FLM-M) resemble bone marrow macrophage (BMM) morphology and express similar macrophage surface markers as BMM. In comparison to granulocyte monocyte-colony stimulating factor (GM-CSF) derived FLM (FLM-G), FLM-M have higher surface expression of CD11b, CD68, CD14 and CD64, and lower expression of CD11c. BMM, FLM-M and FLM-G all produce TNFα and IL-6 in response to lipopolysaccharide activation. BMM and FLM-M cells have similar phagocytic properties with 99.3% of BMM and FLM-M actively phagocytosing opsonized sheep erythrocytes and a phagocytic efficiency of 0.9. The average number of internalized erythrocytes per cell was higher (13.1±10.0) in BMM than in FLM-M (7.6±2.9). FLM-G had fewer actively phagocytic cells (86%), lower phagocytic efficiency (0.7) and fewer internalized erythrocytes per macrophage (4.2±2.1) than BMM or FLM-M. Principal component analysis and hierarchical clustering demonstrated mRNA expression profiles were more similar between BMM and FLM-M cells than FLM-G. Transcriptome comparison to the ImmGen tissue atlas shows cultured BMM and FLM-M cluster with macrophage progenitors and bone marrow macrophages. In conclusion, FLM-M cell cultures share major morphological, phenotypic and functional properties of BMM except for senescence, and can be an effective substitute to BMM. These new cells will facilitate study of macrophage biology by enabling experiments requiring long-term culture or genetic modifications.

Loss of GM-CSF-dependent instruction of alveolar macrophages in COVID-19 provides a rationale for inhaled GM-CSF treatment (RNA-Seq)

Project description:Systemic GM-CSF promotes myelopoiesis and inflammation and GM-CSF blockade is being evaluated as treatment for COVID-19-associated hyperinflammation. Alveolar GM-CSF is however required for monocytes to differentiate into alveolar macrophages (AM) that control alveolar homeostasis and dampen inflammation. By mapping cross-species AM development stages to clinical lung samples, we discovered that COVID-19 is marked by defective GM-CSF-dependent AM instruction and accumulation of proinflammatory macrophages. In a multi-center, open-label, randomized, controlled trial in 81 non-ventilated COVID-19 patients with respiratory failure, we found that inhalation of rhu-GM-CSF did not improve mean oxygenation parameters compared with standard treatment. However, more patients on GM-CSF had a clinical response, and GM-CSF inhalation induced higher numbers of virus-specific CD8 effector lymphocytes and class-switched B cells, without exacerbating systemic hyperinflammation. This translational proof-of-concept study provides rationale for further testing of inhaled GM-CSF as non-invasive treatment to improve alveolar gas exchange and simultaneously boost anti-viral immunity in COVID-19
