Recently it has been observed in preclinical models that that radiation enhances the recruitment of circulating tumor cells to primary tumors, and results in tumor regrowth after treatment. This process may have implications for clinical radiotherapy, which improves control of a number of tumor types but which, despite continued dose escalation and aggressive fractionation, is unable to fully prevent local recurrences. By irradiating a single tumor within an animal bearing multiple lesions, we observed an increase in tumor cell migration to irradiated and unirradiated sites, suggesting a systemic component to this process...

Granulocyte-macrophage colony-stimulation factor plays different crucial roles during embryo implantation and subsequent development. Here we aimed to evaluate the effects of embryo cell culture medium, with the inclusion of granulocyte-macrophage colony-stimulation factor (GM-CSF), on embryo development and pregnancy rate. To this end, we took advantage of our retrospective observational study to correlate the outcomes from two different culture media. We included in this study 25 unselected patient from our IVF Center that underwent heterologous IVF cycle with crypreserved oocytes...

High mobility group box 1 (HMGB1) is a non-histone DNA-binding protein, secreted into the extracellular milieu in response to inflammatory stimuli. The secreted HMGB1 mediates various inflammatory diseases, including periodontitis; however, the underlying mechanisms of HMGB1-induced periodontal inflammation are not completely understood. Here, we examined whether anti-HMGB1 neutralizing antibody inhibits periodontal progression and investigated the molecular pathology of HMGB1 in vitro and in vivo In vitro analysis indicated that HMGB1, granulocyte-macrophage colony-stimulating factor (GM-CSF), and interleukin-1β (IL-1β) were secreted in response to tumor necrosis factor-α (TNF-α) stimuli in human gingival epithelial cells (HGECs) and human monocytic leukemia cells (THP-1) treated with phorbol myristate acetate...

INTRODUCTION: Tuberculosis (TB) remains a huge worldwide burden, despite extensive vaccination coverage with the Bacillus Calmette-Guérin (BCG), the only vaccine available against this disease, indicating that BCG-driven immunity is inadequate to protect the human population against TB. This underscore the critical necessitate to develop an improved TB vaccine, based on a better understanding of host-pathogen interactions and immune responses during mycobacterial infection. AIM OF THE WORK: To examine whether the exogenous addition of IFN-β could improve dendritic cell (DC) response to Mycobacterium bovis (M...

Monocytes are considered refractory to porcine reproductive and respiratory syndrome virus type 1 (PRRSV-1) infection. However, monocytes are only short-lived in blood, being able to differentiate into macrophages and dendritic cells (DC). It was therefore merited to revisit PRRSV-1 interaction with monocytes, particularly those treated with cytokines influencing monocyte biology. Thus, several factors were screened, particularly those modulating monocyte differentiation and expression of putative PRRSV-1 receptors (CD169 and CD163)...

How to induce immune tolerance without long-term need for immunosuppressive drugs has always been a central problem in solid organ transplantation. Modulating immunoregulatory cells represents a potential target to resolve this problem. Myeloid-derived suppressor cells (MDSCs) are novel key immunoregulatory cells in the context of tumor development or transplantation, and can be generated in vitro . However, none of current systems for in vitro differentiation of MDSCs have successfully achieved long-term immune tolerance...

The widely used influenza subunit vaccine would benefit from increased protection rates in vulnerable populations. Skin immunization by microneedle (MN) patch can increase vaccine immunogenicity, as well as increase vaccination coverage due to simplified administration. To further increase immunogenicity, we used granulocyte-macrophage colony stimulating factor (GM-CSF), an immunomodulatory cytokine already approved for skin cancer therapy and cancer support treatment. GM-CSF has been shown to be upregulated in skin following MN insertion...

Occupational exposure to indium tin oxide (ITO) particles has been associated with the development of severe lung diseases, including pulmonary alveolar proteinosis (PAP). The mechanisms of this lung toxicity remain unknown. Here, we reveal the respective roles of resident alveolar (Siglec-Fhigh AM) and recruited interstitial (Siglec-Flow IM) macrophages contributing in concert to the development of PAP. In mice treated with ITO particles, PAP is specifically associated with IL-1α (not GM-CSF) deficiency and Siglec-Fhigh AM (not Siglec-Flow IM) depletion...

A subset of bladder patients does not respond to BCG treatment effectively and the underlying reason behind this observation is currently unclear. CD4+ T cells are composed of various subsets that each expresses a distinctive set of cytokines and can potently shift the immune response toward various directions. In this study, we examined the CD4+ T-cell cytokine response in bladder cancer patients toward BCG stimulation. We found that bladder cancer patients presented a variety of responses toward BCG, with no uniform characteristics...

Radiation-induced intestinal fibrosis (RIF) is a serious complication after abdominal radiotherapy for pelvic tumor or peritoneal metastasis. Herein, we show that RIF is mediated by eosinophil interactions with α-smooth muscle actin-positive (α-SMA+ ) stromal cells. Abdominal irradiation caused RIF especially in the submucosa (SM) of the small intestine, which was associated with the excessive accumulation of eosinophils in both human and mouse. Eosinophil-deficient mice showed markedly ameliorated RIF, suggesting the importance of eosinophils...

In this study, Compritol ATO-based Resveratrol colloidal carriers (CCCs) were prepared. In most formulae, the use of a binary-mixture of surfactants improved the physicochemical properties. CCC6 (containing P407/P188 as bi-surfactants) attained the highest drug loading, release efficiency during 24 hr and occlusive effect for 48 hr; in addition to, a uniform particle size distribution within the desired range. In-vivo studies were done based on the analysis of anti-oxidant markers [catalase (CAT), reduced glutathione (GSH) and superoxide dismutase (SOD)], anti-inflammatory markers [interleukin 6 (IL-6), interleukin 8 (IL-8) and rat Nuclear factor-kappa B (NF-κB)] and anti-wrinkling markers [matrix metalloproteinase (MMP-1) and Granulocyte-macrophage colony-stimulating factor (GM-CSF)], after UVB-irradiation...

Glucocorticoids (GCs) are potent anti-inflammatory drugs whose mode of action is complex and still debatable. One likely cellular target of GCs are monocytes/macrophages. The role of GCs in monocyte survival is also debated. Although both granulocyte macrophage-colony stimulating factor (GM-CSF) and macrophage-CSF (M-CSF) are important regulators of macrophage lineage functions including their survival, the former is often associated with proinflammatory functions while the latter is important in lineage homeostasis...

GM-CSF promotes the functional maturation of lung alveolar macrophages (A-MØ), whose differentiation is dependent on the peroxisome proliferator-activated receptor gamma (PPARγ) transcription factor. In fact, blockade of GM-CSF-initiated signaling or deletion of the PPARγ-encoding gene PPARG leads to functionally defective A-MØ and the onset of pulmonary alveolar proteinosis. In vitro , macrophages generated in the presence of GM-CSF display potent proinflammatory, immunogenic and tumor growth-limiting activities...

AIM: To examine the relationship between elevated granulocyte-macrophage colony-stimulating factor (GM-CSF) auto-antibodies (Ab) level and time to surgical recurrence after initial surgery for Crohn's disease (CD). METHODS: We reviewed 412 charts from a clinical database at tertiary academic hospital. Patients included in the study had ileal or ileocolonic CD and surgical resection of small bowel or ileocecal region for management of disease. Serum samples were analyzed for serological assays including GM-CSF cytokine, GM-CSF Ab, ASCA IgG and IgA, and genetic markers including SNPs rs2066843, rs2066844, rs2066845, rs2076756 and rs2066847 in NOD2, rs2241880 in ATG16L1, and rs13361189 in IRGM...
