The quest for an effective HIV vaccine presents new possibilities, challenges

...ge because the virus is unusually well-equipped to elude immune defenses," says Dr. Fauci. "Much progress has been made; however, we must continue research efforts to improve our understanding of HIV and how it evades the immune system, to design new vaccine candidates and to assess the most promising ones...

Scientists identify specific enzymes that make meningitis hard to fight

...s play in the process that enables the bacteria to elude the body's natural defences could eventually help scientists develop novel new treatments for meningitis and the septicaemia it can cause.

Tiny Tampa Bay fish key to evolution of immune system

... similar to ours that enable it to also skillfully elude attack. "This influences our therapeutic strategy because we must consider that an organism we are trying to target may have an elaborate defensive system of its own, with features that neutralize what we're trying to do to it," Ostrov said.

Pressured by predators, lizards see rapid shift in natural selection

...ster-running -- Anolis lizards would be favored to elude capture. However, as the lizards grew ever more arboreal in habitat, the scientists projected that natural selection would begin to favor shorter limbs, which are better suited to navigating narrow branches and twigs. Their hypothesis was borne ou...

Touching Molecules With Your Bare Hands

For a virus to survive, it must elude the ever vigilant immune sentinels of its host. A latent virus can escape immune detection if it resides in nondividing cells and doesn’t produce any proteins. No viral proteins means no red flags for immune cells. If the virus targets one of the man...
