Rapid Recruitment of CD14+ Monocytes in Experimentally Induced Allergic Rhinitis in Human Subjects
Researchers assessed the role of mucosal mononuclear phagocytes, consisting of monocytes, macrophages, and dendritic cells, in local allergic inflammatory reaction. [J Allergy Clin Immunol] Abstract

Decreased B and T Lymphocyte Attenuator in Behcet’s Disease May Trigger Abnormal Th17 and Th1 Immune Responses
Researchers investigated whether B and T lymphocyte attenuator (BTLA) activation could be exploited to inhibit the development of abnormal immune responses in Behcet’s disease (BD) patients. BTLA expression in PBMCs and CD4+ T cells was significantly decreased in active BD patients. [Sci Rep] Full Article

Tumor-Derived Exosomes Regulate Expression of Immune Function-Related Genes in Human T Cell Subsets
Changes in the gene profiles of primary human T lymphocytes exposed in vitro to exosomes were evaluated. CD4+ Tconv, CD8+ T or CD4+ CD39+ Treg were isolated from normal donors’ peripheral blood and co-incubated with tumor cell-derived exosomes or exosomes isolated from supernatants of cultured dendritic cells. [Sci Rep] Full Article

An Adaptive Immune Response Driven by Mature, Antigen-Experienced T and B Cells within the Microenvironment of Oral Squamous Cell Carcinoma
For a deeper understanding of the role of the infiltrating-lymphocytes in oral squamous cell carcinoma, scientists characterized the lymphocyte infiltrate repertoires and defined their features. [Int J Cancer] Abstract

A Comparison of the Ability of the Human IgG1 Allotypes G1m3 and G1m1,17 to Stimulate T-Cell Responses from Allotype Matched and Mismatched Donors
Researchers investigated the potential of human IgG1 allotypes to stimulate responses in human CD4+ T cells from donors matched for homologous and heterologous IgG1 allotypes. [mAbs] Full Article

Secukinumab, a Novel Anti-IL-17A Antibody, Shows Low Immunogenicity Potential in Human In Vitro Assays Comparable to Other Marketed Biotherapeutics with Low Clinical Immunogenicity
To gain insight into possible explanations for the clinically observed low immunogenicity of secukinumab, investigators evaluated its immunogenicity potential by applying two different in vitro assays: T-cell activation and MAPPs (major histocompatibility complex–associated peptide proteomics). [mAbs] Abstract

Identifying Patient-Specific Epstein-Barr Nuclear Antigen-1 Genetic Variation and Potential Autoreactive Targets Relevant to Multiple Sclerosis Pathogenesis
Investigators utilized standard and next-generation sequencing techniques to investigate Epstein-Barr nuclear antigen-1 sequence variation and its relationship to HLA-DR15 binding affinity, and examined potential cross-reactive immune targets within the central nervous system proteome. [PLoS One] Full Article

Cytomegalovirus Infection Minimally Affects the Frequencies of B-Cell Phenotypes in Peripheral Blood of Younger and Older Adults
Researchers compared peripheral blood B-cell differentiation phenotypes of 140 age- and gender-matched cytomegalovirus (CMV)-seronegative or -seropositive adults aged between 24 and 85 years. They found that the frequencies of naïve B-cells within the CD19+ population were not significantly different in younger and older CMV-seronegative people. [Gerontology] Abstract

Functional Specialty of CD40 and Dendritic Cell Surface Lectins for Exogenous Antigen Presentation to CD8+ and CD4+ T Cells
The authors report the superiority of CD40 over nine different lectins and scavenger receptors at evoking antigen-specific CD8+ T cell responses. However, lectins were more efficient than CD40 at eliciting CD4+ T cell responses. [EBioMedicine] Full Article

CD4+HLA-G+ Regulatory T Cells: Molecular Signature and Pathophysiological Relevance
Scientists focus on the current knowledge on defining features and functioning of human leukocyte antigen G (HLA-G)+CD4+ thymus-derived regulatory T cells as well as their emerging role in various pathologies with special emphasis on the pathogenesis of multiple sclerosis. [Hum Immunol] Abstract

Involvement of B Cells in Non-Infectious Uveitis
The authors summarize the evidence for B-cell involvement in non-infectious uveitis, and consider the potential contributions of B cells to the development and control of the disease. Manipulations of B cells and/or their products are promising new approaches to the treatment of non-infectious uveitis. [Clin Transl Immunol] Full Article

Immune Therapy for Brain Tumors: A New Promising Avenue
A new two-drug combination, currently in early clinical trials, might help people diagnosed with glioblastoma to fight the disease. Scientists reported that a large number of study participants responded well to the drug combination.

PDS Biotechnology Signs Agreement with National Cancer Institute
PDS Biotechnology and the National Cancer Institute (NCI) aim to co-develop several immunotherapies through Phase II clinical trials utilizing combinations of Versamune® with NCI- and PDS-sourced tumor-related proteins or their fragments recognized by the immune system in prostate, breast, and HPV-related cancers. [PDS Biotechnology Corporation] Press Release

Clinical Trial Offers New Drug Combo to Fight Lung Cancer
The Phase III clinical trial, called “Neptune,” compares a combination of two immune drugs with standard chemotherapy. It is one of the first clinical trials to test immune drugs as a first line treatment for lung cancer. [University of New Mexico Comprehensive Cancer Center] Press Release
