Protective gene may enhance vaccine responses
...five times as many memory T cells. "Drugs based on protective
factors such as Spi2A could provide an enormous boost to vaccines," said study author Philip Ashton-Rickardt, professor of pathology and a member of the committee on immunology at the University of Chicago. "This could allow us to extend the duratio...
Schizophrenia gene variant linked to risk traits

immunity to influenza virus infection, the antigenic structure of proteins that stimulate immune responses changes significantly over time, a process known as antigenic drift, so in most years the influenza vaccine has to be updated to ensure suffici...
Researchers in UGA Vet School discover a mechanism that blocks replication of a retrovirus

Impact of Earth's rising atmospheric carbon dioxide found in world oceans

calcium carbonate shells in many species of marine organisms at high CO 2 levels, including corals and plankton, drifting plants and animals on which other marine life feeds. "Based on our present knowledge, it appears that as seawater CO 2 levels...

Crystal structure for anthrax-cell binding complex
...r. Anthrax toxin is comprised of three proteins: protective
antigen (PA), lethal factor (LF), and edema factor (EF). To gain entry into host cells, PA must recognize a receptor on the surface of the target cell. Once PA has bound to the cell, it then enables EF and LF to bind and form a pore through which P...
