WebJan 24, 2024 · Signal transduction induced by chimeric antigen receptors (CARs) is generally believed to rely on the activity of the SRC family kinase (SFK) LCK, as is the case with T cell receptor (TCR) signaling. Here, we show that CAR signaling occurs in the absence of LCK. WebCARs are designed based on T cell receptor (TCR) signaling and the recognition specificities of antibodies. This technology has achieved great clinical success in combatting cancers. Despite these successes, the mechanism of CAR signaling in the T cell and how this can impact function is not fully understood.
