Contemplating Langerhans and marginal zone B cells: they appear to deliver the antigens to FDC

Do lymphatic Langerhans deliver antigens to the Germinal center Follicular Dendritic Cell like the marginal zone B cells in the spleen?

If only langerhans and Marginal zone B cells interact with the FDC giving it antigens then what do they have in common? (langerhans at the lymph and MZB at the spleen)

Hypothesis Review:
alpha herpes use beta estrogen receptor hsv1 hsv2 zoster
beta herpes use estrogen related receptors cmz hhv6 hhv7
gamma herpes use alpha estrogen receptors EBV hhv8

marker for FDC is cd21
