Question
The following statements are made about how CD4 T cells provide help to CD8 T cells. A. Antigen/MHC-11 complexes on CD4 T cells interact with antigen/MHC-1 complexes on CD8 cells. B. A single dendritic cell (DC) presents antigen on MHC-1 and MHC-11 at the same time. C. CD4 T cells activate DCs which produce chemokines like CCL3 and CCL4 that can specifically attract CD8 T cells to form a CD4-CD8-DC triad. D. CD4 T cells help B cells, which differentiate into plasma cells and secrete antibodies that form immune complexes which bind to FcyRs on CD8 T cells. Which one of the following options represents the combination of all correct statements?
Explanation
In the following statements are made about how, B and C represents established outcome. functional assays confirms option C (B and C) as correct, while alternatives misstate substrate or regulatory direction, contradicting textbook data.
