ABSTRACT:
The HTLV-1 immortalized human polyclonal T cell line, MT-2, was continuously exposed to low doses of chrysotile-B (CB) for more than half a year to estimate the long-term cell biological effects of silicate on the human T lymphocytes. The appearance of apoptosis, production of cytokines and expression of several genes will be discussed.
