Caltech Scientists Show Why Anti-HIV Antibodies are Ineffective at Blocking Infection

Lori Oliwenstein

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.

Caltech Biologists Spy on the Secret Inner Life of a Cell

Kathy Svitil

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.

Africa's Greatest Health Dangers to be Addressed at Caltech May 3

Jill Perry

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.

Southern California Institutions to Collaborate on Stem Cell Research

Kathy Svitil

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.

Baltimore Offered $13.9 Million from Grand Challenges in Global Health Initiative for AIDS Research

Jill Perry

The Grand Challenges in Global Health initiative, a major effort to achieve scientific breakthroughs against diseases that kill millions of people each year in the world's poorest countries, today offered 43 grants totaling $436.6 million for a broad range of innovative research projects involving scientists in 33 countries, including David Baltimore, president of the California Institute of Technology. The ultimate goal of the initiative is to create "deliverable technologies"--health tools that are not only effective, but also inexpensive to produce, easy to distribute, and simple to use in developing countries.

Caltech biologists reveal structure of protein responsible for weight loss in cancer and AIDS patients

Robert Tindol

Caltech biologists have determined the three-dimensional structure of a protein that causes wasting in cancer and AIDS patients. The discovery could lead to new strategies for controlling weight loss in patients with devastating illnesses-and conversely, perhaps new strategies for fighting obesity.
