WebOf note, 73% to 90% of the TFHscells within CLNs were positive for SIV p27 antigen. As such, it appears that not only do the FDCs retain SIV they also transmit them (via B cells) to TFHswithin these CLNs. This interaction results in infection of TFHsin the CLNs. WebIn addition to trapping immunocomplexes and exposing antigen to B cells, FDCs express adhesion molecules, cytokines, and chemokines that help the localization and retention of both B and T cells in the GC. Indeed, FDCs lacking VCAM-1 and ICAM-1 adhesion molecules are unable to support the GC reaction, including affinity maturation [71].
