Immunotherapies that induce durable immune control of chronic HIV infection may eliminate the need for life-long dependence on drugs. We investigated a DNA vaccine formulated with a novel genetic adjuvant that stimulates immune responses in the blood and gut for the ability to improve therapy in rhesus macaques chronically infected with SIV. Using the(More)
Some narcotic drugs have been reported to produce increases in muscle tone in rats. In our laboratory we have found that etonitazine produces a 'lead-pipe' rigidity of the trunk and limb musculature. The reported studies were conducted to characterize etonitazine-induced rigidity more fully, to compare the degree of rigidity with that produced by morphine,(More)
Large unilamellar vesicles (LUV) composed of phosphatidylserine are capable of encapsulating poliovirus ribonucleic acid (RNA) and delivering it efficiently to cells in an infectious form. The biological activity of vesicle-entrapped poliovirus RNA was 1-2 x 10(4) plaque forming units/nanogram (pfu/ng) and appeared to be enhanced by ribonuclease treatment(More)
We have selected Chinese hamster ovary (CHO) cells resistant to infection by encephalomycarditis (EMC) virus. Thus far, we have obtained five lines resistant to EMC, all of which manifest different phenotypes. Three of the five are not persistently infected with virus, while two lines produce infectious virus and grow in its presence. The nonpersistently(More)
