T-cells shown to infiltrate brain, cause respiratory distress in condition affecting the immunocompromised

When an immunocompromised person’s system begins to recover and produce more white blood cells, it’s usually a good thing—unless they develop a potentially deadly inflammatory condition. New research from the University of Illinois Urbana-Champaign has found that the pulmonary distress often associated with the condition is caused not by damage to the lungs, but by newly populated T-cells infiltrating the brain.
