In a recent paper, Schriek et al. show that, in a complement-dependent reaction, marginal zone B cells (MZBs) steal MHC class II (MHCII) from dendritic cells (DCs). Activation of T cells by stolen MHCII complexes potentially allows MZBs to augment or regulate T cell activation in ways that are distinct from DCs.

Introduction: Challenges remain in reducing antigen escape and tumor recurrence while CAR-T cell therapy has substantially improved outcomes in the treatment of multiple myeloma. T cell receptor fusion construct (TRuC)-T cells, which utilize intact T cell receptor (TCR)-CD3 complex to eliminate tumor cells in a non-major histocompatibility complex (MHC)-restricted manner, represent a promising strategy. Moreover, interleukin-7 (IL-7) is known to enhance the proliferation and survival of T cells.

Previous research has highlighted the critical role of amino acid metabolism (AAM) in the pathophysiology of sepsis. The present study aimed to explore the potential diagnostic and prognostic value of AAM-related genes (AAMGs) in sepsis, as well as their underlying molecular mechanisms. Gene expression profiles from the Gene Expression Omnibus (GSE65682, GSE185263 and GSE154918 datasets) were analyzed.

Background: Small extracellular vesicles (sEV) released by tumor cells (tumor-derived sEV; TEX) mediate intercellular communication between tumor and non-malignant cells and were shown to impact disease progression. This study investigates the relationship between the expression levels of the vesiculation-related genes linked to sEV production and the tumor microenvironment (TME).
Methods: Two independent gene sets were analyzed, both previously linked to sEV production in various non-malignant or malignant cells.

Follicular dendritic cell-secreted protein (FDC-SP) is produced by follicular dendritic cells, periodontal ligament and junctional epithelium (JE). JE exists immediately apical to the bottom of the pocket and binds enamel with hemidesmosomes to protect the periodontium from bacterial infection. To analyze the transcriptional regulation of the FDC-SP gene by interleukin-6 (IL-6), we performed real-time PCR, Western blotting, immunofluorescence, luciferase (LUC) assays, gel mobility shift and chromatin immunoprecipitation (ChIP) assays using Ca9-22 and Sa3 gingival epithelial cells.

Heligmosomoides polygyrus co-infection is reported to have protective antiviral effects against pulmonary viral infections. To investigate a potential underlying mechanism, we infected C57BL/6 mice with H. polygyrus larvae for two weeks.
