Investigational T-Cell Receptor Therapy Achieves Encouraging Clinical Responses in Multiple Myeloma Patients
Researchers modified T cells to attack cancer cells expressing NY-ESO-1, an antigen found in nearly 60 percent of multiple myelomas and previously shown to be associated with tumor growth and poor prognosis.

Genomic Landscape of Cutaneous T Cell Lymphoma
Scientists performed exome and whole-genome DNA sequencing and RNA sequencing on purified cutaneous T cell lymphoma (CTCL) and matched normal cells. The results implicate mutations in 17 genes in CTCL pathogenesis, including genes involved in T cell activation and apoptosis, NF-κB signaling, chromatin remodeling and DNA damage response.

Interleukin-12 and -23 Control Plasticity of CD127+ Group 1 and Group 3 Innate Lymphoid Cells in the Intestinal Lamina Propria
Researchers found that differentiation of ILC3 to CD127+ ILC1 is reversible in vitro and in vivo. CD127+ ILC1 differentiated to ILC3 in the presence of interleukin-2 (IL-2), IL-23, and IL-1β dependent on the transcription factor RORγt, and this process was enhanced in the presence of retinoic acid.

Mesenchymal Stromal Cells Prevent Allostimulation In Vivo and Control Checkpoints of Th1 Priming: Migration of Human DC to Lymph Nodes and NK Cell Activation
Scientists investigated the impact of mesenchymal stromal cells on the functionality of human myeloid dendritic cells (DCs) and the consequences for natural killer (NK) cell and Th1 priming in vitro and in vivo. [Stem Cells] Abstract

Evidence for the Involvement of Gamma Delta T Cells in the Immune Response in Rasmussen Encephalitis
Peripheral blood mononuclear cells and brain-infiltrating lymphocytes were isolated from 20 Rasmussen encephalitis surgery specimens by standard methods, and CD3+ T cell populations were analyzed by flow cytometry. [J Neuroinflamm] Full Article

Opportunistic Pathogen Candida albicans Elicits a Temporal Response in Primary Human Mast Cells
Scientists showed that human mast cells mounted specific responses towards C. albicans. Collectively, mast cell responses included the launch of initial, intermediate and late phase components determined by the secretion of granular proteins and cytokines. [Sci Rep] Full Article

Characterization of Species-Specific Genes Regulated by E2-2 in Human Plasmacytoid Dendritic Cells
Basic helix-loop-helix protein E2-2 is defined as an essential transcription factor for mouse plasmacytoid dendritic cells (pDCs) development, cell fate maintenance and gene program. The authors investigated the function of E2-2 in human pDCs and screened human-specific genes regulated by E2-2. [Sci Rep] Full Article

Analysis of CD8+ Treg Cells in Patients with Ovarian Cancer: A Possible Mechanism for Immune Impairment
Scientists investigated CD8+ regulatory T (Treg) cells in ovarian cancer patients and their in vitro induction. Compared with the CD8+ T cells cultured alone, the CD8+ Treg cells induced in vitro by coculture with SK-OV-3/A2780 showed increased CTLA-4 and Foxp3 expression and decreased CD28 expression. [Cell Mol Immunol] Full Article

Caspase-4 Mediates Non-Canonical Activation of the NLRP3 Inflammasome in Human Myeloid Cells
Researchers showed that the human monocytic cell line THP1 activates the inflammasome in response to cytosolic LPS in a TLR4-independent fashion. This response is mediated by caspase-4 and accompanied by caspase-1 activation, pyroptosis and interleukin 1β maturation. [Eur J Immunol] Abstract

Advances on Non-CD4+ Foxp3+ T Regulatory Cells: CD8+, Type 1, and Double Negative T Regulatory Cells in Organ Transplantation
The overwhelming body of research on T regulatory cells (Treg) has focused on CD4+ CD25+ Foxp3+ T cells. However, recent years have witnessed a resurgence in interest in CD4CD8+, CD4CD8, and CD4+Foxp3 type 1 Treg and their role in controlling autoimmune diseases and in promoting the survival of organ allografts and xenografts. [Transplantation] Abstract

Origin and Functions of Pro-Inflammatory Cytokine Producing Foxp3+ Regulatory T Cells
The authors review the mechanisms of development and the possible functions of pro-inflammatory cytokine producing Foxp3+ Tregs. [Cytokine] Abstract
