Question: The production of an effector helper T cell from of a nai?ve helper T cell requires multiple sign... The production of an effector helper T cell from of a nai?ve helper T cell requires multiple signals from an activated dendritic cell. These may include: A. Co-stimulatory proteins on helper T cell surface, including CD28, and secreted cytokines. B. Input from the central nervous system to lymph nodes. C. Co-stimulatory proteins on the dendritic cell surface, including CD28, and secreted cytokines. D. MHC–peptide complexes on the dendritic cell surface provide one signal, by binding to both TCRs and a CD4 co-receptor on the T cell.
Explanation / Answer
answer- MHC–peptide complexes on the dendritic cell surface provide one signal, by binding to both TCRs and a CD4 co-receptor on the T cell.
specialised APCs are primarily dendritic cells , macrophagic & b cells, dendritic cells are only cell group that expres mhc class II molecules.
