IL-1β, IL-4 and IL-12 Control the Fate of Group 2 Innate Lymphoid Cells in Human Airway Inflammation in the Lungs
Investigators report that interleukin 1β (IL-1β) directly activated human group 2 innate lymphoid cells (ILC2s) and that IL-12 induced the conversion of these activated ILC2s into interferon-γ (IFN-γ)-producing ILC1s, which was reversed by IL-4. [Nat Immunol] Abstract

Lentiviral Hematopoietic Stem Cell Gene Therapy for X-Linked Severe Combined Immunodeficiency
Follow-up data from two older patients demonstrated that lentiviral vector γc transduced autologous hematopoietic stem cell gene therapy after nonmyeloablative busulfan conditioning achieves selective expansion of gene-marked T, NK, and B cells, which is associated with sustained restoration of humoral responses to immunization and clinical improvement at two to three years after treatment.

CD19 CAR-T Cells of Defined CD4+:CD8+ Composition in Adult B Cell ALL Patients
Researchers conducted a clinical trial to evaluate CD19 chimeric antigen receptor (CAR)-T cells that were manufactured from defined CD4+ and CD8+ T cell subsets and administered in a defined CD4+:CD8+ composition to adults with B cell acute lymphoblastic leukemia (ALL) after lymphodepletion chemotherapy.

Critical Role of CD2 Co-Stimulation in Adaptive Natural Killer Cell Responses Revealed in NKG2C-Deficient Humans
Assessment of natural killer (NK) cell repertoires in 60 NKG2C−/− donors revealed a broad range of NK cell populations displaying characteristic footprints of adaptive NK cells, including a terminally differentiated phenotype, functional reprogramming, and epigenetic remodeling of the interferon-γ promoter. [Cell Rep] Full Article | Graphical Abstract

Immunomodulation by Mesenchymal Stem Cells in Treating Human Autoimmune Disease-Associated Lung Fibrosis
The authors aimed to define the immunopathology involved in pulmonary exacerbation during autoimmunity and to determine the potential of mesenchymal stem cells (MSCs) in correcting these disorders. T cell subsets involved in the process of connective tissue diseases (CTD-IP) were defined, while the regulatory functions of MSCs isolated from the bone marrow of normal individuals on cytotoxic T cells and CTD-UIP human primary lung fibroblasts were investigated in vitro. [Stem Cell Res Ther] Full Article

Characterization of the Immunomodulatory Effects of Meningococcal Opa Proteins on Human Peripheral Blood Mononuclear Cells and CD4+ T Cells
Researchers investigated the effects of various Opa+ and Opa antigens from Neisseria meningitidis strain H44/76 in a range of in vitro conditions using peripheral blood mononuclear cells and purified CD4+ T cells, measuring T cell proliferation by CFSE dilution using flow cytometry. [PLoS One] Full Article

TNF Is a Key Cytokine Mediating Neutrophil Cytotoxic Activity in Breast Cancer Patients
Scientists assessed the cytotoxicity of neutrophils from 90 newly diagnosed breast cancer patients, 24 ductal carcinoma in situ patients, 56 metastatic breast cancer patients, and 64 women with no history of cancer. They report that neutrophils from metastatic and newly diagnosed breast cancer patients are significantly more cytotoxic than neutrophils from cancer-free individuals. [npj Breast Cancer] Full Article

PD-1 Marks Dysfunctional Regulatory T Cells in Malignant Gliomas
In both patients with glioblastoma multiforme and healthy subjects, circulating programmed cell death protein 1 (PD-1)hi Tregs displayed reduced suppression of CD4+ effector T cells, production of IFN-γ, and molecular signatures of exhaustion.

T Cell Responses to Cytomegalovirus
The authors discuss the molecular triggers that promote memory inflation, the idea that memory inflation could be considered a natural pathway of T cell maturation that could be harnessed in vaccination, and the broader implications of cytomegalovirus infection and the T cell responses it elicits. [Nat Rev Immunol] Abstract

Trained Immunity: A Program of Innate Immune Memory in Health and Disease
The discovery of trained immunity may open the door for novel vaccine approaches, new therapeutic strategies for the treatment of immune deficiency states, and modulation of exaggerated inflammation in autoinflammatory diseases. [Science] Abstract

Toxicity and Management in CAR T-Cell Therapy
Abrogating toxicity has become a critical step in the successful application of chimeric antigen receptor (CAR) T cell technology. To this end, investigators review the reported and theoretical toxicities of CAR T cells and their management. [Mol Ther Oncolytics] Abstract
