- Cryptococcus gattii is an emerging fungal pathogen that is acquired through the respiratory tract and causes invasive infections in both immunocompromised and otherwise healthy people. Many of these apparently immunocompetent patients are subsequently found to have autoantibodies against the pleiotropic cytokine GM-CSF. In this study, we investigated the potential role of GM-CSF (or CSF2) in the host response to C. gattii using a murine model of infection. Interestingly, infected Csf2-/- mice were found to have significantly improved survival and decreased lung fungal burden compared to wild type (WT) mice. We determined that during C. gattii infection, GM-CSF promotes the differentiation of monocytes into alveolar and interstitial macrophages. When these macrophages are ablated in CCR2-DTR+ mice, there is a corresponding improvement in survival with decreased lung fungal burden, thus phenocopying Csf2-/- mice. WT bone-marrow derived macrophages challenged with C. gattii and interstitial and alveolar macrophages from infected WT mice are unable to undergo M1 polarization, suggesting that monocyte-derived macrophages (moMacs) are rendered permissive for fungal proliferation. Therefore, GM-CSF and moMacs mediate immune responses that are harmful to the host. We further found that GM-CSF and moMacs preferentially promote the influx of eosinophils over neutrophils into the infected lung which is associated with substantial inflammatory lung pathology. Ablation of neutrophils using Mrp8cretg iDTR+ mice significantly increased C. gattii burden in the lungs, indicating that GM-CSF and moMacs block the entry of these beneficial, fungal-clearing granulocytes during infection. Altogether, our results show that GM-CSF plays a key role in impeding host anti-fungal responses to C. gattii by coordinating monocyte-derived macrophages and granulocyte activity and crosstalk. - Source: PubMed

Immunonutrition approach with selected bioactive compounds may have beneficial effects on nutritional status and immune tolerance mechanisms. We evaluated the effects of an immunonutrition approach, based on the use of a novel multicomponent food supplement containing prebiotics, postbiotics, vitamin D3, docosahexaenoic acid (DHA), extracts, and Quercetin in children with CMA. - Source: PubMed

Carucci LauraCaldaria ErikaOglio FrancaIorio Raffaele FedericoMauriello VittoriaMasino AntonioCoppola Serena - Myofibroblastic cancer-associated fibroblasts (myoCAFs) represent a crucial stromal cell subpopulation associated with tumor growth, relapse, and metastasis. In this study, we identify a noncanonical mechanism through which head and neck cancer cells regulate myoCAF activation. Co-culture with tumor organoids promoted the expression of cytokine interaction-related genes and myoCAF phenotypic markers in paracancerous fibroblasts (PFs). Cytokine and tissue array analyses revealed that upregulation of colony-stimulating factor-2 (CSF2) in tumor cells correlated with overexpression of nicotinamide N-methyltransferase (NNMT) in CAFs. Notably, CSF2 treatment enhanced myoCAF properties in a NNMT-dependent manner, while NNMT overexpression remained largely unaffected by transforming growth factor-β (TGF-β). In both assembled organoid and xenograft models, tumor growth was reduced when either CSF2 in cancer cells or CSF2 receptor subunit CSF2RA in CAFs was knocked down. Mechanistically, CSF2 induced FOS phosphorylation at Ser32, promoting nuclear translocation of phosphorylated FOS (p-FOS) to regulate NNMT transcription. In drug screening assays, CSF2 blockade partially overcame resistance to TGF-β inhibition. These findings establish the CSF2/FOS/NNMT axis as a TGF-β-independent pathway driving myoCAF activation. - Source: PubMed

Li RuiYang XiaoLi YitongDuan YilingWu YufeiZhao HuiShang Zhengjun - Allergic diseases, encompassing allergic asthma, atopic dermatitis, food allergies, have emerged as substantial global public health challenges, with IgE-stimulated mast cell and basophil playing pivotal roles in disease pathogenesis. Our prior research has indicated the potential therapeutic effects of Ginkgo biloba leaf (GBL) extracts in IgE-mediated mast cell degranulation. The present study aimed to identify key genes and pathways associated with IgE-mediated mast cell and basophil responses and explore the mechanisms of GBL components. Initially, DEGs and WGCNA analysis were employed to preliminarily identify candidate genes associated with IgE stimulation in GSE96696 dataset. Subsequently, transcriptomic analysis was conducted on an anti-DNP IgE-induced RBL-2H3 degranulation model to validate the key genes, including Egr1, Tnfaip3, Nfkbid, Il13, Nfkbia, Il3, Il4, Ccl7, Cdkn1a, Csf2, Rel, alongside crucial signaling pathways such as NF-κB, and PI3K-AKT pathways. Machine learning algorithms were then applied to confirm the predictive capacity of key genes. Building upon these findings, molecular biology experiments, molecular docking, and molecular dynamics simulations demonstrated that GBL flavonoids, including quercetin, amentoflavone, ginkgetin, and bilobetin, significantly inhibited the release of cytokines, blocked calcium ion influx, and suppressed degranulation potentially by targeting RELA and AKT1. Collectively, our findings not only identify key genes for IgE-mediated response but also provide preliminary mechanistic insights into GBL. - Source: PubMed

Ren YueWu MinxuanLiu KaiyangZhang LingheZhang YanlingQin Wen - Microglia-the predominant immune cell of the central nervous system (CNS)-possess an astounding capacity for proliferation. In development, this proliferation ensures that microglia are present at a sufficient density to perform their vital functions throughout development and into adulthood. During diseases or following CNS injuries, microglial proliferation similarly promotes an increase in microglial density to respond to damage. However, the governing mechanisms for microglial proliferation remain unknown. While many factors have been suggested to promote microglial proliferation-known as mitogens-or to increase microglial densities both in vitro and in vivo, there has been no standardized comparison of these factors. Here, we screened 22 of these factors in serum-free microglial cultures which more faithfully recapitulate in vivo microglial biology. We confirmed three cytokines-colony stimulating factor-2, interleukin-3 and tumor necrosis factor-ɑ-promote microglia proliferation. We similarly tested the remaining non-mitogenic factors for an indirect ability to regulate microglial proliferation by conditioning media from other CNS cell lineages and measuring the capacity for conditioned media to promote microglial proliferation. Of the tested factors and lineages, only interleukin-1ɑ and interleukin-1β promoted the release of a microglial mitogen from astrocytes, which we confirmed to be CSF2. Together, we demonstrate that in standardized conditions, very few factors that were previously reported to promote microglial proliferation or increase microglial densities, are directly, or indirectly, mitogenic. - Source: PubMed
