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.

Mix-and-match immune regulators

Go check out the article on the Emory Office of Technology Transfer’s site on Jacques Galipeau and the artificial chimeric immune stimulators he’s invented. He and his colleagues take one immune regulatory molecule, GM-CSF, and stick it onto others, creating a series of potent immune stimulants he calls “fusokines.” According to Galipeau, one of them turns antibody-producing B cells into The Hulk. Another is like a five hour energy drink.

These super-stimulants may be especially ray ban outlet effective in the realm of cancer, where the immune system is not responding to a stealthy threat. But in dealing with autoimmune diseases such as multiple sclerosis or inflammatory bowel disease, it is more necessary to rein in over-enthusiastic immune cells. Galipeau has devised a fusokine that apparently reprograms cells into being more orderly.
