Respiratory syncytical virus-induced chemokine expression in the lower airways: eosinophil recruitment and degranulation.

abstract：:Although transbronchial lung biopsy (TBBx) is widely acknowledged as the "gold standard" for diagnosis of acute rejection, controversy exists regarding the need to perform follow-up procedures. Over a 5-yr period, we performed 1,142 TBBx of which 173 were follow-up TBBx in 99 patients with pulmonary allograft rejectio...
