- Abstract
- Lung carcinoma cell lines (NCI-N417, NCI-NI46, NCI-H69, PC-14) were
evaluated on their expression of HLA-class I with W6/32 antibody and HLA-class II
with L243 by flow cytometry. Also examined were the killing and/or cytolytic effects
of allogeneic NK cells and T lymphocytes as effector cells to the lung carcinoma cell
lines by chromium release assay, before and after treatments with gamma interferon.
HLA class I expressions significantly increased after treatment with gamma interferon
(P <0.05), whereas HLA class II expressions showed no differences (P > 0.05). The
killing and/or cytolytic effects of allogeneic NK cells very significantly decreased after
treatment with gamma interferon (P <0.001), while those of the T lymphocytes showed
either no change or a tendancy to decrease (P > 0.05).
