The expression of the EBV latent membrane protein (LMP-1) is independent of CD23 and bcl-2 in Reed-Sternberg cells in Hodgkin''s disease

A series of 33 cases of Hodgkin's disease was investigated for the presence of the EBV encoded latent gene product LMP-1 and of CD23 using immunohistochemical techniques. The expression of bcl-2 was examined in a subset of cases. LMP-1 was detected in the Reed-Sternberg cells in 15 cases. Although LMP-1 is known to upregulate CD23 and bcl-2, there was no correlation between the expression of LMP-1 and the detection of CD23 and bcl-2 in Reed-Sternberg cells.
