Interleukin-2, interferon-gamma and natural killer cell activity in bronchoalveolar lavage fluid from marrow transplant recipients with cytomegalovirus pneumonia.
Cytokines interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) were measured from bronchoalveolar lavage (BAL) fluid and sera of 41 marrow transplant recipients and eight healthy volunteers as controls. Although IL-2 and IFN-gamma were detected in 32 and 10 patient sera respectively, IL-2 or IFN-gamma was detected in BAL of only five patients. There was no correlation of the presence of either cytokine with cytomegalovirus pneumonia, pneumonia of other etiology or absence of pneumonia. Local lung production of IL-2 and IFN-gamma as measured in BAL did not correlate with natural-killer cell activity and had no apparent role in the pathogenesis of lung disease after marrow transplant.
