These iTreg are a distinct subset of regulatory cells that phenotypically and functionally differ from FOXP3+ natural (n) Treg responsible for peripheral tolerance. They mediate powerful suppression of effector T cells via diverse mechanisms, produce immunosuppressive cytokines, notably TGF-β as well ...
Naïve cells are non-active lymphocytes that recognize and bind to specific antigens, become activated, and launch target attacks against foreign pathogens.
The immune system relies on specialized "effector" T cells to fight off pathogens, but in chronic infections like HIV or cancers, the perpetual activation of these cells can turn them into "exhausted" T cells unable to continue fighting. In the new study, Salk scientists discovered that a nut...
The stages in development are mediated by different molecular mechanisms, involving control of gene expression and chromatin remodeling. This review centers on the factors, cellular interactions, and molecular mechanisms involved in the maturation of nave CD4 + T lymphocytes into fully effector cells. ...

Mast cells (MCs) are principal effector cells of type-I-allergic reactions but still poorly defined in humans. The consortium Functional Annotation of the Mammalian Genome 5 has created a map of body-wide transcriptome data for a multitude of human cell types, including MCs. MCs were found to...

Terminal buttons release neurotransmitters into the synaptic cleft, facilitating communication with other neurons or effector cells. 9 Why are dendritic spines important for neural function? Dendritic spines increase the surface area of dendrites, allowing for more synaptic connections and enhancing the neur...
Abnormal tumor microenvironment and immune escape in multiple myeloma (MM) are associated with regulatory T cells (Tregs), which play an important role in maintaining self-tolerance and regulating the overall immune response to infection or tumor cells.
