immune response

Scientists have shown how a parasitic worm infection common in the developing world increases susceptibility to tuberculosis. The study demonstrated that treating the parasite reduces lung damage seen in mice that also are infected with tuberculosis, thereby eliminating the vulnerability to tuberculosis (TB) that the parasite is known to cause.

A new study led by Michael J. Holtzman, MD, at the School of Medicine suggests that a fundamental antiviral defense mechanism is intact in asthma. This indicates that another aspect of the immune system must explain the difficulty people with asthma have when they encounter respiratory viruses.
