ATL-derived factor (ADF) is an acid protein, molecular weight about 13KD, which is related to cell classification, activation, and various viral infections. The localization of ADF was studied in the lung tissues of HTLV-I associated bronchiolo-alveolar disorder : HABA, diffuse panbronchiolitis : DPB, and idiopathic interstitial pneumonia : IIP. The localization of ADF in the lung tissues was demonstrated by immunohistochemical staining with anti-ADF antibody as the first antibody, which was made by affinity purification. In all 4 cases of HABA, one of 6 cases of DPB, and two of 5 cases of IIP, staining of the lung tissue was positive. ADF was demonstrated in the bronchial epithelia, alveolar epithelia, vascular endothelia, and desquamative cells in HABA cases as the result of the study. ADF was also restrictively demonstrated in bronchial epithelia in DPB and IIP cases. The case of DPB in which ADF was demonstrated also showed positive HTLV-I related reaction. In conclusion, the localization of ADF in the lung tissues was demonstrated in HABA, DPB and IIP, suggesting immunological abnormalities based upon infections from HTLV-I or a related retrovirus.
