Based on the previous report of sensitivity of a single SAIDS-NHL-derived cell line to TGF-β1-mediated inhibition [20], an investigation was initiated to determine whether the finding could be recapitulated in LCL8664, a SAIDS-NHL-derived cell line from the Tulane National Primate Research Center characterized morphologically as immunoblastoid DLBCL [8]. Here, TGFB1 is linked to non-Hodgkin lymphoma.
