Steve Reiner, MD, professor of Medicine, and Burton Barnett, a doctoral student in the Reiner lab at the Perelman School of Medicine at the University of Pennsylvania, have shown how immune cells, called B lymphocytes, are able to produce daughter cells that are not equal, a finding that might explain how lifelong antibodies are made after vaccination.
Scientists at the Gladstone Institutes have discovered new protein fragments in semen that enhance the ability of HIV, the virus that causes AIDS, to infect new cells—a discovery that one day could help curb the global spread of this deadly pathogen.
Chronic infections by viruses such as HIV or hepatitis C eventually take hold because they wear the immune system out, a phenomenon immunologists describe as exhaustion.
New research from the laboratory of Dr. Elizabeth Leadbetter at the Trudeau Institute may lead to a whole new class of vaccines. Dr. Leadbetter's lab has discovered new properties of a potential vaccine adjuvant that suggest it could be useful for enhancing protection against a number of different infections.
University of Iowa researchers and colleagues have discovered how malaria manipulates the immune system to allow the parasite to persist in the bloodstream.
A new treatment using leukemia patients' own infection-fighting cells appears to protect them from infections and cancer recurrence following treatment with fludarabine-based chemotherapy, according to new research from the Perelman School of Medicine at the University of Pennsylvania.
