Abstract

Flt3-лиганд может быть использован для генерирования большого числа дендритных клеток из гематопоэтических предшественников и стволовых клеток. Flt3-лиганд может быть использован для усиления иммунного ответа in vivo и размножения дендритных клеток ex vivo. Такие дендритные клетки могут далее быть использованы для презентирования опухолевых, вирусных или других антигенов незрелым T-клеткам, могут быть использованы как адъюванты вакцин.Международная заявка была опубликована вместе с отчетом о международном поиске.
