News


NIH article on HIV latency in cells paper and work done by Vyjayanthi Krishnan in Steven L. Zeichner's laboratory posted August 16, 2004


BioCentury (The Bernstein Report on BioBusiness), Vol 12, Number 37, p A9 of 18 published on August 23, 2004 called "HIV hide and seek" was based on an interview with Dr Krishnan. In the article they quotes her as saying that "There is no real phenotype difference between a cell that is not infected and a cell that is latently infected." - Vyjanthi Krishnan of NCI (National Cancer Institute).
