Interferon (IFN)γ content in the bronchoalveolar lavage (BAL) at various time points after delivery of adenoviral gene vector expressing murine granulocyte-macrophage colony-stimulating factor (AdGM-CSF) or Addl70-3.

BAL fluids were collected at days 4, 7, 12, and 19 postintranasal delivery of AdGM-CSF or Addl70-3, and IFNγ content was determined by enzyme-linked immunosorbent assay. The results are expressed as mean ± SEM for AdGM-CSF group (n = 3) and mean for Addl70-3 group (n = 2).
