Abstract

Настоящее изобретение относится к биспецифической молекуле полипептида, включающей первую полипептидную цепь и вторую полипептидную цепь, обеспечивающие связывающий участок, полученный из Т-клеточного рецептора (ТКР), специфичного к вирусному пептидному эпитопу, ассоциированному с главным комплексом гистосовместимости (МНС), и связывающий участок, полученный из антитела, способного к привлечению иммунных эффекторных клеток человека за счет специфического связывания с поверхностным антигеном указанных клеток, а также к способам получения биспецифической молекулы полипептида и их применению.
