[The superficial markers of neoplastispecificity of c cell line MT-4 and perspectives of its application as a model for studying activity of immune modulating preparations.]

The article considers expression of markers of activation of neoplastic CD4+ T-lymphocytic transplantable cellular line M T-4, transformed by T-lymphotropic human virus type I. It is demonstrated that in cells are detected such external proteins as CD25+, CD28+, CD38+, CD62L+, CD69+, CD95+ and HLA-DR+. The maximal number of these components was detected in three days after transplantation of cells. These indices reached average level for markers CD25+, CD28+, CD38+, CD69+, CD95+ and HLA-DR+ - more than 90% and for CD62L+ - 48%. The obtained results and cultivation of cells indicate that cells MT-4 can be used as a convenient model for testing of activity of immune modulation preparations.
