The aim of this study was to determine how the mucosal immunity mediated by T cells is developed in the vagina. Antigen-presenting cells and T cells play important roles in the early process of host defense.

A mathematical model to study the impact of intra-tumour heterogeneity on anti-tumour CD8+ T cell immune response [PDF]
Intra-tumour heterogeneity (ITH) has a strong impact on the efficacy of the immune response against solid tumours. The number of sub-populations of cancer cells expressing different antigens and the percentage of immunogenic cells (i.e. tumour cells that are effectively targeted by immune cells) in a tumour are both expressions of ITH. Here, we present

Cell-by-cell deciphering of T cells in allergic inflammation [PDF]
Technical advances in single-cell RNA sequencing (scRNA-seq) render it possible to examine the transcriptomes of single cells in patients with allergic inflammation with high resolution in the context of their specific microenvironment, treatment, and disease status.

LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Confirmation that T cell receptor activation is digital, not analog. Hence individual T cell cytolytic capacity is independent of initial stimulation strength [PDF]
Whether a sub-optimum lymphocyte stimulus is achieved by lowering ligand concentration, or decreasing its affinity, initial TCR activation responses are likely to be digital. We now know for cultured peripheral blood mononuclear cells (PBMCs), when activated by plant lectins such as concanavalin-A (Con-A), that the responding cells are T cells, and ...

Cell–cell and cell–matrix interactions
In this year's annual ASCB Meeting Minisymposium on Cell–Cell and Cell–Matrix Interactions, new data were presented on several aspects of the biology of cell adhesions. The role of cell adhesions in cancer was the topic of three of the talks, two of which were focused on identifying how invasion is affected by cell–matrix and cell–cell adhesions ...

The cell secretome, a mediator of cell-to-cell communication [PDF]
We are witnessing the emergence of a novel type of biological regulation, namely, the communication between cells via their secreted substances, the secretome. This brief overview is based on the available published data and our own experience. We discuss three vignettes illustrating the importance of communication via the secretome: (1) the secretome ...

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells
Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

Molecular Genetics of T Cell Development [PDF]
T cell development is guided by a complex set of transcription factors that act recursively, in different combinations, at each of the developmental choice points from T-lineage specification to peripheral T cell specialization. This review describes the
