The activation of T cells requires engagement of the T cell receptor/CD3 complex and co-stimulatory molecules , and results in the triggering of several signaling pathways which lead rapidly to the nuclear translocation of several transcription factors , such as nuclear factor (NF)-kappa B and NF-AT .
 protein: NF-AT; protein: transcription factors; protein: nuclear factor (NF)-kappa B; protein: co-stimulatory molecules; cell type: T cells; protein: T cell receptor/CD3 complex
