Scientists Discover Antibody That Neutralizes 98% of HIV Strains (inquisitr.com)

An anonymous reader quotes a report from The Inquisitr: The National Institute of Allergy and Infectious Diseases (NIAID) announced this week that a "remarkable" breakthrough has been made in the study of preventing and treating the human immunodeficiency virus (HIV), the virus that leads to acquired immunodeficiency syndrome (AIDS), according to a press release posted on the agency's official website. The breakthrough centers around the discovery of a powerful antibody named N6 that is highly effective in both binding to the surface of the HIV virus and neutralizing it. The former has proved elusive in the past. "Identifying broadly neutralizing antibodies against HIV has been difficult because the virus rapidly changes its surface proteins to evade recognition by the immune system," the press release explains. The antibody was initially discovered in an HIV-positive person and has since proven to potentially neutralize 98 percent of HIV isolates, "including 16 of 20 strains resistant to other antibodies of the same class," according to the press release. Researchers have had previous success with other antibodies, but N6 appears to be more effective. The new discovery has potential benefits far beyond preventing and treating HIV as well. Studying exactly how N6 works could potentially lead to breakthroughs in other anti-viral antibodies. "Findings from the current study showed that N6 evolved a unique mode of binding that depends less on a variable area of the HIV envelope known as the V5 region and focuses more on conserved regions, which change relatively little among HIV strains," NIAID explains. "This allows N6 to tolerate changes in the HIV envelope, including the attachment of sugars in the V5 region, a major mechanism by which HIV develops resistance to other VRC01-class antibodies. Due to its potency, N6 may offer stronger and more durable prevention and treatment benefits, and researchers may be able to administer it subcutaneously (into the fat under the skin) rather than intravenously. In addition, its ability to neutralize nearly all HIV strains would be advantageous for both prevention and treatment strategies."

Its an evolution of earlier work done looking for broadly neutralizing antibodies against HIV, they did some basic in vitro work to show that their antibody could potently interact with a variety of strains of HIV, then did a bunch of structural work. The paper is missing any in vivo work and it makes one wonder why that would have been left out. It would clearly have been published in science/nature/cell instead of immunity with some basic in vivo work, and the fact that its missing in a story like this is very odd. Primates are a bitch to work with (although with the number of authors on the paper and the fact that this took place at the Institute should have made primate usage a real possibility), but mice should not have been a problem at all. There are plenty of HIV and lentiviral infectious models in mice. They're crappy but they're better than nothing.

    Well not exactly.
    The discovery of an antibody that targets a non-variable site is important in several ways. I'm not sure how good a therapeutic drug it will make. Antibodies are huge and hard to make so depending on the dose required it could be prohibitive to inject enough of the stuff in an active form to do any good. Massive proteins often are lousy drugs. THat's not to say that antibodies can't be used as drugs. There's a lot that are on the market now, for example Humira. But that's going after receptors in the host not viruses so it's a different regime.

    But what is good about this is three things. You learn where you can bind on the virus, you learn the binding mode of the contact points, and finally you learn that that binding mode is protective across most HIV. It's not uncommon to have something that binds HIV well but fails to be protective. Given this structural knowledge one can now try to design either small molecules or other smaller proteins than an anti-body that bind in a similar manner and target either the same binding site or the same origins of protection.
