CD40LG and non-Hodgkin lymphoma: Upon exposure of BJAB cell line to CD40L L cells, the full length form (113 kD) remained detectable, at level close to that of untreated BJAB cells (Figure 3A), although the 89 kD form remained present in cell lysates; similar observations were made in the other 4 NHL cell lines (not shown) for 4 of the 5 cytotoxic agents tested (not CDDP).
