Can you point me to the data in the papers referenced that backs up the disguise claim?
PGS, this is the best I can do w/o more research. Perhaps the papers of Dr. Thorpe will have more of the information you're seeking, if you're sufficiently interested:
Dr. Melina Soares, lead study author and UT Southwestern instructor of pharmacology, commented, "Recent non-affiliated research has further confirmed that exposed PS has immunosuppressive properties and is also clarifying its involvement during viral infection of cells. Our data go a step further, providing compelling evidence that exposed PS itself is a promising anti-viral drug target that is involved in the pathogenesis of multiple viruses, suggesting the possibility of achieving broad-spectrum anti-viral effects using a single anti-PS agent. We look forward to further exploring the potential of bavituximab and other anti-PS antibodies against viruses for which there are few or no effective therapeutic options."
