Volume 8, Issue 2, February 2011
2011 is starting out pretty well for this handsome MRL threesome. This month, their groups published back-to-back papers in Clinical and Vaccine Immunology describing the serology of leprosy in humans and armadillos. One of these papers has been selected as one of the American Society for Microbiology’s papers of the month! Check it out in the "Journal Highlights" section of the upcoming March edition of the ASM publication Microbe.
Searching the MIP archives, we found what we believe is a photo of this same trio from the 70’s. Click here to help us verify the resemblance.
Congratulations to Alexa Dickson, a postdoctoral fellow in the Wilusz2 labs, for being selected as the sole awardee in a American Society for Microbiology national competition for the Heatley-Payne Exchange Program Award for Early Career Scientists. Alexa will receive $4,000 to cover transportation, housing and registration expenses to attend the annual scientific meeting of the Society for General Microbiology meeting in Harrogate, England this April. Following the meeting, Alexa will spend ~ a week in the laboratory of Dr. Sheila Graham in the University of Glasgow to enhance US-UK collaborative science. Assuming she survives the haggis, this should be a truly exciting opportunity for Alexa!
On Feb 16th, MIP’s Brian Foy joined a panel of four CSU faculty members at 6.023 x 1023 (aka Avogadro’s Number) on Mason Street to discuss the relationships between climate change and infectious diseases.

An Aptamer-siRNA Chimera Suppresses HIV-1 Viral Loads and Protects from Helper CD4+ T Cell Decline in Humanized Mice

Yes faithful readers of the MIPnews, for the first time in history we have an MIP laboratory who has garnered back-to-back MIPublication of the Month honors! Ramesh Akkina and his collaborators at the City of Hope have come out with a very exciting approach to harness the awesome power of in vitro-evolved RNA aptamers and RNA interference. In this paper in the Science spin off Science Translational Medicine journal, they report on a form of ‘superdrug’ that not only effectively targets HIV in cells but appears to overcome one of the main hurdles for these RNA-based technologies – effective in vivo delivery.
Ramesh et al make their superdrug in a very straightforward fashion on a ribonucleic acid synthesizer and the way works is extremely elegant. One half of the drug (the ‘aptamer’ region) folds into a structure that binds the HIV gp120 glycoprotein with nanomolar affinity (yes Virginia, RNA is such a cool molecule that you can even train it to recognize most anything with very high affinity). Therefore this moiety specifically targets the superdrug to the surface of HIV infected cells (since gp120 is expressed on the cell surface) and allows the superdrug to be effectively taken up by the cells via natural endocytosis. In addition to targeting, this aptamer portion also possesses some anti-HIV efficacy as well since it can presumably neutralize virus infectivity by interfering with gp120 function. The other half of the superdrug is a standard siRNA that targets the tat/rev common exon of the HIV genome. This provides the second punch, and perhaps the knockout blow, to HIV via targeting viral RNAs for degradation by the RNAi machinery in the cell. In this manuscript, Preston, Leila, Jes et al test the superdrug in the lab’s RAG-hu mice that contain a humanized immune system and can be persistently infected with HIV. The superdrug knocks down HIV virus load by three orders of magnitude or greater, protects the animal’s CD4+ T cells from depletion, shows a duration of protection for several weeks and evidence to date indicate that HIV has not been able to generate any dominant mutations that allow for easy viral escape from the drug. In summary, this work very significantly extends the group’s initial 2009 studies with this superdrug in tissue culture cells and we think represents a very attractive approach to complement the published antibody-based delivery methods for dispensing siRNAs to specific cells in the body to combat viral infections.
So why did we choose this paper for the coveted title of MIPublication of the Month®? First, this is an extremely cool application of a pair of RNA-based technologies to combat the major viral pathogenic scourge on the human population over the last 30 years. Since HIV has a propensity to evolve resistance to many small molecule therapeutics, any and all new antiviral technologies are extremely welcome. Do we really need to list any additional reasons??? ‘Nuff said.
Congratulations once again to Preston and Ramesh on being our first repeat Pub of the Month authors. Do I hear chants of ‘three-peat’ in the hallway?
