Recent evidence suggests a role for natural killer (NK) cells in the control of multiple myeloma. We show that expression of the NK cell receptor DNAM-1 (CD226) is reduced on CD56(dim) NK cells from myeloma patients with active disease compared with patients in remission and healthy controls. This suggested that this receptor might play a role in NK-myeloma interactions. The DNAM-1 ligands Nect...
Toxins are effective in cell killing if internalized efficiently. Conjugation of the plant toxin saporin with basic fibroblast growth factor has increased tumor killing due to better internalization, but toxin uptake by cells has remained relatively inefficient. We show here that infection of melanoma cells with a replication-defective adenovirus enhances cell killing by the mitotoxin basic fib...

Human protectin (CD59) is an 18-20-kD membrane glycoprotein that restricts lysis of human erythrocytes and leukocytes by homologous complement. By directly incorporating protectin into membranes of heterologous cells we observed that protectin did not prevent perforin-mediated killing, whereas complement killing was effectively restricted. Further, no significant enhancement of cell-mediated ki...
