 Which line is not true for follicular dendritic cells?

#Unit 4. Cell Communication and Cell Signaling
  1. follicular dendritic cells do not arise in bone marrow and have completely different functions from those described for the dendritic cells.
  2. Follicular dendritic cells do not function as antigen-presenting cells for TH-cell activation. These dendritic cells were named for their exclusive location in organized structures of the lymph node called lymph follicles, which are rich in B cells.
  3. Follicular dendritic cells do function as antigen-presenting cells for TH-cell activation. These dendritic cells were named for their exclusive location in organized structures of the lymph node called lymph follicles, which are rich in B cells.
  4. the interaction of B cells with follicular dendritic cells is an important step in the maturation and diversification of B cells.
