Humoral immunity in phenotypes of chronic lung allograft dysfunction: A broncho-alveolar lavage fluid analysis

We demonstrated increased levels of immunoglobulins and complement proteins dominantly present in rCLAD. This leads to the belief that antibodies and AMR might play a more important role in rCLAD compared to BOS. Therefore, anti B-cell therapy could offer beneficial therapeutic effects in patients diagnosed with rCLAD, which needs further research.
