Reed Sternberg Cells

However those cells that have an imbalance in pro and anti apoptotic proteins ratio could represent a transforming event rescuing pre apoptotic gc b cells from apoptotic stimuli and finally could give rise to hodgkin and reed sternberg cells they described bcl 2 and bak cytoplasmic expression in 83 3 and 92 per cent of the cases together with p53 nuclear expression 89 9 per cent of the cases.
