Two chemicals boost immune cells' ability to fight HIV without gene therapy

...udy, the scientists isolated immune cells from the blood of HIV-infected persons and cultured the cells with the chemical compounds. They were surprised to see that the compounds produced the same three changes in the cells as those created by the gene therapy. "Lo and behold, we discovered we didn't need...

The mice retained triglycerides in the liver with a commensurate decrease of circulating triglycerides in the bloodstream. Insulin response to glucose load was diminished in LGKO mice, thus glucose to...
