[University of Leicester] Study Finds a ‘Balanced’ Immune Response in the Lungs Is Key to Protection From Developing TB

University of Leicester news release

An early view of the immune responses in the lungs of people that have recently been exposed to TB has provided clues to why some people keep the infection in check, while others develop disease, suggesting new ways to intervene earlier and stop it.

Researchers used bronchoscopy to collect fluid from the lower airways of people living in the same household as someone with TB.

Analysis of samples of the fluid suggests that the balance of inflammatory neutrophils and T cells in the airways may be a key determinant of whether an infected individual progresses to TB or remains healthy.
