T-cells 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 C-IRIS, a potentially deadly inflammatory condition. New research has found that the pulmonary distress often associated with C-IRIS is caused not by damage to the lungs, but by newly populated T-cells infiltrating the brain. Knowing this mechanism of action can help researchers and physicians better understand the illness and provide new treatment targets.
