Is gain of distal chromosome arm 17q associated with poor prognosis in neuroblastoma?
Although the most frequent aberration in neuroblastoma to date, we found no association between 17q gain and an inferior prognosis in our cohort; the status of MYCN and 11q, however, allowed reliable prediction of patients' outcomes.
Donor HLA class I-specific cytotoxic T-lymphocyte activity directed at airway epithelial cells was demonstrated in bronchoalveolar lavage lymphocytes from lung transplant recipients. Lysis of these targets was significantly higher during episodes of acute rejection.
