Trained Immunity in Newborn Infants of HBV-Infected Mothers Scientists demonstrated that Hepatitis B virus (HBV) exposure in utero triggered a state of trained immunity, characterized by innate immune cell maturation and Th1 development, which in turn enhanced the ability of cord blood immune cells to respond to bacterial infection in vitro. [Nat Commun] Full Article | Press Release CD14-Expressing Cancer Cells Establish the Inflammatory and Proliferative Tumor Microenvironment in Bladder Cancer Using bladder cancer as a model, scientists found that CD14-high cancer cells expressed higher levels of numerous inflammation mediators and form larger tumors compared with CD14-low cells. [Proc Natl Acad Sci USA] Abstract | Full Article Characterization of Macrophage – Cancer Cell Crosstalk in Estrogen Receptor Positive and Triple-Negative Breast Cancer Researchers performed whole transcriptome sequencing of human monocytes that were co-cultured with estrogen receptor positive or triple-negative breast cancer cell lines and studied the biological responses related to the differential gene activation in both monocytes and cancer cells by pathway analysis. [Sci Rep] Full Article FoxP3+ and IL-17+ Cells Are Correlated with Improved Prognosis in Cervical Adenocarcinoma To study whether the infiltration of T cell subpopulations was correlated with cervical adenocarcinoma patient survival, similar to squamous cell carcinoma, the tumor-infiltrating T cells, Tregs, Th17 cells and IL-17+ cell frequencies were analyzed in a cohort of cervical adenocarcinoma patients. [Cancer Immunol Immunother] Full Article High Peripheral Blood Th17 Percent Associated with Poor Lung Function in Cystic Fibrosis Scientists hypothesized that cystic fibrosis (CF)-related T cell regulatory defects could be detected by analyzing CD4+ lymphocyte subsets in peripheral blood. They observed higher proportions of FOXP3+, IL-10+ and TGF-β+ CD4+ cells in CF adults, but not children/adolescents, compared with controls. [PLoS One] Full Article Human Malignant Melanoma-Derived Progestagen-Associated Endometrial Protein Immunosuppresses T Lymphocytes In Vitro Researchers investigated the role of melanoma cell-secreted progestagen-associated endometrial protein (PAEP) in regulating T cell function. Upon the enrichment of CD3+, CD4+ and CD8+ T cells from human peripheral blood mononuclear cells, each subset was then mixed with either melanoma-derived PAEP protein or PAEP-poor supernatant of gene-silenced tumor cells. [PLoS One] Full Article A Change in Inflammatory Footprint Precedes Plaque Instability: A Systematic Evaluation of Cellular Aspects of the Adaptive Immune Response in Human Atherosclerosis Scientists systematically evaluated cellular components of the adaptive immune response in a biobank of human aortas covering the full spectrum of atherosclerotic disease. [J Am Heart Assoc] Full Article Adoptive T-Cell Immunotherapy for Ganciclovir-Resistant CMV Disease after Lung Transplantation Investigators demonstrated successful expansion and adoptive transfer of autologous cytomegalovirus (CMV)-specific T cells from a seronegative recipient of a seropositive lung allograft with ganciclovir-resistant CMV disease, resulting in the long-term reconstitution of protective anti-viral immunity, CMV infection, disease-free survival and no allograft rejection.
