(Multiple Myeloma) :
Neither primary multiple myeloma cells ( MMCs ) nor HMCLs expressed B7-1 or 4-1BBL , and these molecules could not be induced by CD40 triggering
DeBenedette et al., J Immunol 1997
:
We find that 4-1BBL is inducible on splenic B cells by CD40 ligand/CD40 interaction or by culturing of splenic dendritic cells, treatments that also induce B7 family molecules
