Bird flu shuffle probes viral compatibility

The good news is that packaging signals on the H5 and H7 viral RNA genomes are often incompatible with the H3N2 viruses. But mix and match still occurred at a low level, particularly with Read more

A life consumed by sleep

Nothing he tried had worked. For Sigurjon Jakobsson, the trip to Atlanta with his family was a last-ditch effort to wake up. He had struggled with sleeping excessively for several years before coming from Iceland to see a visionary neurologist, who might have answers. In high school, Sigurjon was a decathlete competing as part of Iceland’s national sports team. But at the age of 16, an increasing need for sleep began to encroach upon his life. Read more

Blue circles show how viral levels stayed low even after antiretroviral drugs were stopped.

The Science paper was featured on NIH director Francis Collins’ blog this week. NIAID director Anthony Fauci has been giving presentations on the research, which emerged from a collaboration from his lab and Tab Ansari’s at Emory. Fauci’s talk at the recent HIV prevention meeting in Chicago is viewable here.

At Lab Land, we were pleased to see that the watchdogs at Treatment Action Group had this to say:

“Media coverage of the paper has generally been accurate, but has had to wrestle with the uncertainty that exists among scientists regarding how ART-free control of viral load should be described.”

HIV pioneer Robert Gallo noted in an article accompanying the Science paper that the anti-integrin antibody treatment represents an emerging alternative to the vaunted “shock and kill” strategy, which he termed “soothe and snooze.” Note to reporters: the upcoming “Strategies for an HIV cure” conference at NIH in mid-November might be a good chance to compare the different strategies and put them in perspective.
