FKN gene expression in lymph nodes.

FKN gene expression was analyzed in lymph nodes from 4 HIV-infected (A,B) and 4 uninfected (not shown) patients by in situ hybridization with an antisense probe. (A) T-cell zone. (B) Border between the germinal center (GC) and the T-cell zone (T). (C) Control hybridized with a sense probe. Original magnification × 400 in panels A and B and × 200 in panel C.
