** Modified Vitamin D Binding Protein Macrophage Activator EF-022
Definition :
A modified version of vitamin D binding protein (VDBP ; Gc protein)
macrophage activator, with potential antineoplastic and anti-angiogenic
activities. Upon administration, modified VDBP-macrophage activator
EF-022, acting in a similar manner as VDBP-macrophage activating factor
(GcMAF), is able to activate tumoricidal macrophages, thereby enhancing
the killing and eradication of cancer cells. In addition, EF-022 may
inhibit tumor cell proliferation, migration and angiogenesis. VDBP is a
glycoprotein and precursor for macrophage activating factor (MAF), which
promotes macrophage activation ; however VDBP can be deglycosylated by
serum alpha-N-acetylgalactosaminidase, which is secreted from cancerous
cells, and cannot be converted to MAF. Thus, the macrophage activation
cascade is often impaired in tumor cells and plays a key role in tumor
immunosuppression. Modification of VDBP stabilizes MAF.
