Most potent stimulator of naive T cells:
|A||Mature dendritic cells|
|B||Follicular dentritic cells|
Mature dendritic cells express MHC molecules and costimulatory molecules CD80 and CD86 constitutively on their surfaces and hence are more efficient as antigen presenting cells than the macrophages and the B cells which need to be activated before they can function as antigen presenting cells.
Follicular dendritic cells recognise antigen-antibody complexes and are located in the lymph nodes. They are not antigen presenting cells like the other types of dendritic cells.
