Trapped: Cell-invading piece of virus captured in lab by scientists

This achievement sets the stage to use x-ray crystallography to develop complete images of HIV that include integrase, which in turn will help scientists develop new treatments for the illness. Duane Grandgenett, Ph.D., professor at SLU’s Institute of Molecular Virology and senior author of the study, discovered integrase in 1978, little knowing the piece of virus would provide the basis for an entire class of drugs that now treats HIV…

People with HIV with early-stage cancers are up to four times more likely to go untreated for cancer

Life expectancy for HIV-infected people is now similar to uninfected people, but survival for HIV patients who develop cancer is not. While many studies have attempted to understand why HIV-infected cancer patients have worse outcomes, the new study, the largest of its size and scope, examined differences in cancer treatment as one potential explanation. For early-stage cancers that have the highest chance of cure with appropriate treatment, those with HIV were twice to four times as likely to not receive appropriate cancer treatment, the researchers found…

T-cell research sheds light on why HIV can persist despite treatment

The paper, titled "HIV-1 Persistence in CD4+ T-Cells with Stem Cell-Like Properties," provides evidence that a particular T-cell type may help researchers better understand why HIV can persist despite treatment. Zurakowski’s co-authors include Mathias Lichterfeld, the paper’s lead author, and researchers from Massachusetts General Hospital (MGH); Ragon Institute of MGH, the Massachusetts Institute of Technology and Harvard University; the First Affiliated Hospital of China Medical University; Brigham and Women’s Hospital; and Howard Hughes Medical Institute. Zurakowski explained that HIV treatments do not kill infected cells…
