The influence of the membrane sodium pump activity on the ability of human peripheral blood lymphocytes to form early rosettes with SRBC.

abstract：:Cytotoxic T lymphocytes (CTL) may play an important role in the control of human papillomavirus (HPV)-induced anogenital neoplasias, but have been difficult to study owing to the difficulty in obtaining sufficient quantities of infectious virus. To address this we have stimulated human HPV-specific CTL in vitro using ...
