WebT-follicular helper cells (TFH ), a CD57 + subset of CXCR5 + T cells, lack CCR7, which licenses them to move from the T zone following activation to the follicles where they provide help for B-cell maturation and antibody production. Reciprocally, B cells activated by antigen in the follicles upregulate CCR7 and move toward the T-cell zone. WebCCR7 is a member of the G protein coupled receptor family, which is a subfamily of chemokines. CCR7 was identified to be induced by the Epstein Barr virus (EBV), and is thought to be a mediator of EBV effects on B …
