Jcat T Cells

Jcat T cells are a laboratory T-cell model used to investigate immune-cell activation, signaling, and gene regulation under controlled experimental conditions. When stimulated through the T-cell receptor, these cells initiate intracellular signaling cascades that can include protein phosphorylation, calcium mobilization, and activation of transcription factors, producing measurable changes in cellular behavior or gene expression. Researchers use Jcat T cells to examine how T cells recognize and respond to signals, evaluate molecular pathways involved in immune regulation, and test experimental compounds or genetic modifications. Their reproducibility and accessibility make them useful for connecting fundamental immunology with studies of inflammation, infection, and therapeutic development.

Studying Interactions between Myeloid Cells and CAR T Cells In Vitro and In Vivo

0 Views •

2025

Given the limited xenograft models available to study interactions between human CART and myeloid cells, we established in vitro and in vivo models to understand the impacts of human macrophages on CART cells. Findings can potentially be generalized to evaluate macrophage roles in the tumor microenvironment and test macrophage-targeted immunotherapies.
