Stage fright: don't get over it, get used to it

Many can feel empathy with the situation Banerjee describes: facing “a room full of scientists, who for whatever reason, did not look very happy that Read more

Beyond birthmarks and beta blockers, to cancer prevention

Ahead of this week’s Morningside Center conference on repurposing drugs, we wanted to highlight a recent paper in NPJ Precision Oncology by dermatologist Jack Arbiser. It may represent a new chapter in the story of the beta-blocker propranolol. Several years ago, doctors in France accidentally discovered that propranolol is effective against hemangiomas: bright red birthmarks made of extra blood vessels, which appear in infancy. Hemangiomas often don’t need treatment and regress naturally, but some can lead Read more

Drying up the HIV reservoir

Hope Clinic part of push to optimize HIV vaccine components

Ten years ago, the results of the RV144 trial– conducted in Thailand with the help of the US Army — re-energized the HIV vaccine field, which had been down in the dumps. It was the first vaccine clinical trial to ever demonstrate any efficacy in preventing HIV. The Hope Clinic of Emory Vaccine Center has been involved in efforts to build on the RV144 trial’s promising results. These early-stage studies have been optimizing the best vaccine components and techniques for larger vaccine efficacy trials, some of which are now underway.

Nadine Rouphael, interim director of the Hope Clinic, was first author on a recent paper in Journal of Clinical Investigation, reporting a multi-center study from the HIV Vaccine Trials Network. HVTN is headquartered at the Fred Hutchinson Cancer Research Center in Seattle and supported by the National Institute of Allergy and Infectious Diseases.

“Our study shows that there are tools available to us now to improve on the immunogenicity seen in RV144, which may lead to better efficacy in future field trials,” Rouphael says. (See statement on the HVTN 105 study here.) Read more
