  • Immune System Circuitry That Kills Malaria in Mosquitoes is Identified
    Researchers at the Johns Hopkins Malaria Research Institute have determined the function of a series proteins within the mosquito that transduce a signal that enables the mosquito to fight off infection from the parasite that causes malaria in humans. Together, these ...More

  • Long-Ignored Enzyme is Key to Killing Infectious Bacteria
    New research shows that an enzyme that has long been considered relatively useless to the immune response instead has an important role in setting up immune cells to kill infection-causing bacteria. Ohio State University scientists have determined that this enzyme, called ...More

  • Immune Cells in the Gut May Improve Control of HIV Growth
    The findings of a new study in monkeys may help clarify why some people infected with HIV are better able to control the virus. They also may pinpoint a target for treatment during early HIV infection aimed at increasing the supply of certain immune cells in the gut, which ...More

  • Studies Reveal How Cells Distinguish Between Disease-Causing and Innocuous Invaders
    The specific mechanisms by which humans and other animals are able to discriminate between disease-causing microbes and innocuous ones in order to rapidly respond to infections have long been a mystery to scientists. But a study conducted on roundworms by biologists at UC ...More

  • Rare Immune Cells Could Hold Key to Treating Immune Disorders
    The characterization of a rare immune cell’s involvement in antibody production and ability to ‘remember’ infectious agents could help to improve vaccination and lead to new treatments for immune disorders, say researchers from the Walter and Eliza Hall Institute. ...More

  • HIV 'Superinfection' Boosts Immune Response
    Women who have been infected by two different strains of HIV from two different sexual partners – a condition known as HIV superinfection – have more potent antibody responses that block the replication of the virus compared to women who’ve only been infected once. These ...More

  • Why Getting Healthy Can Seem Worse Than Getting Sick
    A new article in the Quarterly Review of Biology helps explain why the immune system often makes us worse while trying to make us well. The research offers a new perspective on a component of the immune system known as the acute-phase response, a series of systemic changes ...More
