Method and Composition for Inducing Monocyte Cytotoxicity

Summary:
A new cytokine molecule, referred to as Monocyte Cytotoxicity Factor (MCF), has been shown to activate monocytes for tumor cell lysis.  University researchers have developed a line of T-cell hybridomas produce MCFs capable of inducing potent tumor cytotoxicity and high levels of interleukin 1 (1).  Nona-peptides corresponding to the N-terminus of MCF have been developed.  These synthetic peptides were found to interact with specific high affinity saturable cellular binding sites and activate macrophages for cytotoxicity (2).  Therapeutic uses of MCF include the treatment of blood forming organ cancers such as leukemia, or solid tumors by way of direct IV infusion of pharmaceutical compositions that include MCF or in combination with other therapeutic agents such as interleukin II, interferon or Cytoxan.  Use in other therapeutic modalities includes adoptive immunotherapy or the ex vivo activation of a patient's mononuclear cells for reinfusion into the patient.  As a diagnostic, MCF can be useful in detecting T-cell and other malignancies by determining the levels of MCF or the presence of MCF antibodies in blood.
