Using in situ hybridization on sections from non HIV hyperplastic lymph nodes , we found that the gene of the 105 kDa precursor of p50 was overexpressed in the light zone of germinal centers , with a network aspect, which suggested the involvement of follicular dendritic cells ( FDC ).
 ( cell type: FDC, None) , ( protein: 105 kDa precursor, None) , ( protein: p50, None) , ( cell type: follicular dendritic cells, None)
