We aimed at examining NFkappaB translocation in B lymphocytes during in vitro activation through the specific receptor for antigen using a technique convenient in most laboratories such as flow cytometry. We present here an original, convenient, and reproducible technique to study B cell activation events through NFkappaB translocation by means of a novel, specific flow cytometry assay. Intranuclear translocation of NFkappaB p65 was induced after a 45min stimulation; the highest signal was detected for a 10 ng/ml stimulus compared to the unstimulated condition (P< 0.05). Purified CD19+ B cells--cultured in the presence of optimal concentrations of anti-micro fragment Abs (10ng/ml) for 45min at 37 degrees C--induced a mean 60% (range: 45-67%) MFI-- and thus, nuclear NFkappaB translocation-increase. We observed a one-pike profile of NFkappaB staining in PBMC B cells and a two-pike profile of NFkappaB staining in using tonsil B cells. B cells are susceptible to various dysregulations leading to minor to severe pathology (including immunoproliferative disorders). Studies of signal transduction carried out specifically in human B cells, using a novel technique gave considerable advantages: feasibility, sensitivity, reproducibility, ease.
