Phase I Trial of First Ebola Vaccine Based on 2014 Virus Strain Shows Vaccine Is Safe and Provokes an Immune Response
Results from the first Phase I trial of an Ebola vaccine based on the current (2014) strain of the virus suggest that the new vaccine is safe, and provokes an immune response in recipients, although further long-term testing will be needed to establish whether it can protect against the Ebola virus.

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.

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.

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.

Advances and Challenges in Immunotherapy for Solid Organ and Hematopoietic Stem Cell Transplantation
The authors outline the current immunological limitations for hematopoietic stem cell and solid organ transplantation and discusses new immune-modulating therapies in preclinical development and in clinical trials that may allow these obstacles to be overcome. [Sci Transl Med] Abstract

Adoptive Cellular Therapy: A Race to the Finish Line
Using the principles of synthetic biology, advances in cell culture and genetic engineering have made it possible to generate human T cells that display desired specificities and enhanced functionalities compared with the natural immune system. The authors discuss some of the challenges and opportunities that face the field of adoptive cellular therapy. [Sci Transl Med] Abstract
