Aberrations in IL-3, GM-CSF and G-CSF induced signaling are frequently reported in acute myeloid leukemia (AML). Herein, we utilized a unique human myeloid leukemic cell line, AML-193, which responds to all three cytokines to analyze the regulation at microRNA level. Using real-time PCR-based miRNA expression profiling, we investigated miRNA signatures regulated by IL-3, GM-CSF and G-CSF for n=704 miRNAs. We discovered that in addition to regulating specific miRNAs, these cytokines also regulate common set of miRNAs, which includes miR-590-5p, miR-219-5p, miR-15b and miR-628-5p. Taken together, we have identified novel candidate miRNAs that may be instructive during leukemic and normal hematopoiesis.

Host-tissue preference is a critical aspect of parasitic infections and is directly correlated with species diversity. Even the same species, Leishmania donovani, infects the host's bone marrow, spleen, and liver differentially. The tissue-specific persistence of Leishmania results from host-pathogen immune conflicts and arguments.

"Humanized" mice represent promising models to address this deficiency but are limited by variable chimerism and underdeveloped myeloid compartments. We hypothesized that expression of human GM-CSF and IL-3 increases tumor immune cell infiltration, especially myeloid-derived cells, in humanized HCC patient-derived xenografts (PDXs).

Coronary artery disease (CAD) is a leading cause of mortality in the world. It is important to be able to proactively assess the risk of the disease, using novel biomarkers like cytokines that are indicators of inflammation in addition to traditional predictors of risk. Atherosclerosis, the primary cause of CAD, is an inflammatory disease involving cytokines.

Introduction: Due to the high mortality rate and increasing severity of antibiotic resistance, there is a growing interest in new treatments for ae (KP)-induced pneumonia. Research has shown that the single herbs of SiHuangQingXinWan (SHQXW) are effective in treating pneumonia caused by KP. The PI3K/AKT signaling pathway has garnered attention for its potential role in the management of bacterial infections.

UFMylation, a novel ubiquitin-like protein modification system, has been recently found to be activated in inflammation. However, the effects of UFMylation activation on inflammation in vivo remains unclear. In the present study, we generated a UFMylation activated mice using transgenic (TG) techniques.
