Summary: This study found that all common DC subsets are present in the human thymus of various ages, with the density of pDCs gradually increasing with age, suggesting an additional role of pDCs in the thymus beyond central tolerance. The ratio of medulla to cortex area in the human thymus increases with age, while the densities of different DC subsets also show changes.

Summary: This study found that plasma-activated medium (PAM) induced immunogenic cell death in tumor cells and increased the immunogenicity of tumor lysates, enhancing the maturation potential of dendritic cells and promoting cytotoxic T cell responses. Compared to standard methods, this novel approach could be suitable for improving DC-based cancer immunotherapy.

Summary: The study in medaka fish reveals that progenitors first enter a thymic niche favoring the development of gamma delta T cells, and the gradients of interleukin-7 and Ccl25a in the niche influence the lineage outcome. This previously unknown mechanism determines the proportion of alpha beta/gamma delta lineages within species.

Summary: This study developed a novel differentiation protocol to generate human thymic epithelial progenitors from human embryonic stem cells (hES-TEPs) and demonstrated their thymopoietic function in vivo. By incorporating hES-TEPs into a supportive thymic structure, the researchers enhanced human thymocyte development and increased the reconstitution of peripheral CD4+ naive T cells.

Summary: The study reveals the geospatial evolution of cell populations, states, and transcriptomic features in lung adenocarcinoma (LUAD) from normal regions to tumors. LUAD shows significant intratumor cell heterogeneity and transcriptional lineage-plasticity programs. T regulatory cell phenotypes increase near LUAD, while cytotoxic CD8(+) T cells and other cell types decrease in normal tissues.

Summary: HEU newborns have lower percentages of differentiated Th-1, Th-2, Th-17, and CD4(+)CD25(++) T cells in their blood, but the intrinsic abilities of CD4(+) T cells to acquire a Th-1 profile are not affected by the adverse maternal milieu during development. Additionally, under Th-1 differentiation conditions, HEU newborns show higher percentages of CD4(+)IFN-gamma(+) T cells and soluble IFN-gamma compared to HUU newborns.

Summary: Conventional type 1 dendritic cells (cDC1) and conventional type 2 dendritic cells (cDC2) are being considered as alternative options to monocyte-derived dendritic cells (moDCs) in cancer immunotherapy. However, the low numbers of cDCs in peripheral blood and their extensive spontaneous apoptosis and death in culture within 24hrs pose challenges. The study found that GM-CSF improved the viability of both cDC1 and cDC2, while Flt3-L and IL-4 specifically increased the viability of cDC1 and cDC2, respectively. Combinations of these three cytokines further improved the viability of both cDCs at different time points.

Summary: Invariant Natural Killer T (iNKT) cells are a type of lymphocytes that can combat solid and hematological malignancies. They have unique functional features and are attractive for cell immunotherapy. iNKT cells can directly kill cancer cells and suppress immunosuppressive cells in the tumor microenvironment. Moreover, they can be transplanted across MHC barriers without causing alloreaction because of the identical CD1d molecules in all individuals.

Summary: This study describes a workflow for high-dimensional flow cytometry analysis of T cells infiltrating liver metastatic tumor lesions. By optimizing the flow cytometer settings, establishing a multi-color antibody panel, and accurately tuning the dissociation of samples, the phenotypic complexity of T cells infiltrating the tumor lesions was effectively captured. This study provides a robust tool for analyzing complex T cell populations and can be adapted to characterize other relevant pathological tissues.

Summary: Adoptive immunotherapy using T cells engineered with tumor-specific TCRs holds promise for cancer treatment. In this study, researchers harnessed iNKT cells with a second TCR specific for a tumor-associated peptide to generate bispecific effectors for CD1d- and MHC-restricted antigens. The TCR-engineered iNKT cells demonstrated high efficacy in restraining tumor progression and achieved robust cancer control by simultaneously modulating intratumoral suppressive myeloid populations and killing malignant cells. These findings support the potential use of tumor-redirected TCR-iNKT cells and local alpha-GalCer boosting as a therapy for cancer patients.

Summary: In the process of intestinal damage and regeneration, B cells play a dominant role and show expansion of an IFN-induced B cell subset during mucosal healing. Depletion of B cells accelerates recovery, reduces epithelial ulceration, and enhances gene expression programs associated with tissue remodeling. The expansion of B cells impairs interactions between epithelial and stromal cells, hindering mucosal healing.
