Finding an anti-AIDS vaccine remains an elusive goal—partly because the HIV virus quickly mutates to evade the vaccine's antibodies. In a Watson Lecture on April 1, Caltech's Pamela J. Bjorkman will describe ways to neutralize that mutational advantage.

When it comes to a small HIV-fighting protein, called cyanovirin-N, Caltech researchers have found that two are better than one.

Each time a virus invades a healthy individual, antibodies created by the body fight to fend off the intruders. For HIV, the antibodies are very specific and are generated too slowly to combat the rapidly changing virus. However, scientists have found that some HIV-positive people develop highly potent antibodies that can neutralize different subtypes of the virus. Now, a study involving Caltech researchers points to the possibility of using these neutralizing antibodies in the development of a vaccine.

Two scientists from Caltech have been recognized by the National Institutes of Health for their innovative and high-impact biomedical research programs. Michael Roukes, professor of physics, applied physics, and bioengineering, and co-director of the Kavli Nanoscience Institute, and Pamela Bjorkman, Caltech's Max Delbrück Professor of Biology and a Howard Hughes Medical Institute investigator, now join the 81 Pioneers who have been selected since the program's inception in 2004.

Scientists from the Caltech have provided the first-ever glimpse of the structure of a key protein—gp120—found on the surface of a specific subgroup of the human immunodeficiency virus, HIV-1. In addition, they demonstrated that a particular antibody to gp120 makes contact not only with the protein, but with the CD4 receptor that gp120 uses to gain entrance into the body's T cells.

Caltech graduate student Heather D. Agnew is the recipient of the 2010 $30,000 Lemelson-MIT Caltech Student Prize. Agnew is among the four $30,000 Lemelson-MIT Collegiate Student Prize winners. She was recognized for her integral contributions to the development of innovative biochemical protocols that can be utilized for more stable, robust—and inexpensive—detection of diseases like cancer, HIV, or malaria.

Some 25 years after the AIDS epidemic spawned a worldwide search for an effective vaccine against the human immunodeficiency virus (HIV), progress in the field seems to have effectively become stalled. The reason? According to new findings from a team of researchers from Caltech, it's at least partly due to the fact that our body's natural HIV antibodies simply don't have a long enough reach to effectively neutralize the viruses they are meant to target.

The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. Those antibodies, donated by transfer across the placenta before birth or via breast milk after birth, help shape a baby's response to foreign pathogens and may influence the later occurrence of autoimmune diseases. Images from biologists at the California Institute of Technology (Caltech) have revealed for the first time the complicated process by which these antibodies are shuttled from mother's milk, through her baby's gut, and into the bloodstream, and offer new insight into the mammalian immune system.

As conventional means fail to conquer Africa's deadliest diseases-- HIV and malaria--researchers are starting to look outside the box. One solution might be Nobelist David Baltimore's novel approach to combating HIV through gene therapy. He will give the headlining lecture at the Symposium on African Health at the California Institute of Technology May 3 from 10 a.m. to 2 p.m. in Ramo Auditorium on the Caltech campus in Pasadena. Admission is free.

Research institutions across Southern California have joined forces to advance stem cell research by establishing the Southern California Stem Cell Scientific Collaboration (SC3). Members of the collaboration include the California Institute of Technology; University of Southern California; Childrens Hospital Los Angeles; City of Hope; the University of California, Santa Barbara; and the House Ear Institute.
