  • TB Treatment Paradox: Mouse Studies Show Body's Own Response Helps TB Bacteria Survive
    Inhibiting a key immune response in mice during initial multi-drug treatment for tuberculosis could — paradoxically — shorten treatment time for the highly contagious lung infection according to new research from Johns Hopkins Children's Center and the Center for TB ...More

  • 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

  • Babies' Susceptibility to Colds Linked to Immune Response at Birth
    Innate differences in immunity can be detected at birth, according to new research at Washington University School of Medicine in St. Louis. And babies with a better innate response to viruses have fewer respiratory illnesses in the first year of life. “Viral respiratory ...More

  • Biosignatures Distinguish Between Tuberculosis and Sarcoidosis
    The human immune system in action. This colored scanning electron microscope image shows a white blood cell (dyed red) in the act of destroying tuberculosis bacteria (yellow). The bacteria are surrounded by the cell membrane of the scavenger cell, then drawn inside and ...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
