Abstract
Настоящее изобретение относится к антигенраспознающим структурам к опухолеассоциированным антигенам (ТАА), в частности к ТАА ингибиторам серинпротеаз типа Kazal-2 (SPINK2). В частности, в изобретении предложены новые молекулы на основе Т-клеточного рецептора (ТКР), являющиеся селективными и специфическими к экспрессируемому опухолями антигену по изобретению. ТКР по изобретению и связывающиеся с SPINK2 фрагменты, полученные из этого ТКР, применимы для диагностики, лечения и профилактики раковых заболеваний, при которых экспрессируется антиген SPINK2. Предложены также нуклеиновые кислоты, кодирующие антигенраспознающие структуры по изобретению, векторы, включающие данные нуклеиновые кислоты, рекомбинантные клетки, экспрессирующие эти антигенраспознающие структуры, и фармацевтические композиции, включающие соединения по изобретению.The present invention relates to antigen-recognizing structures for tumor-associated antigens (TAA), in particular to TAA Kazal-2 type serine protease inhibitors (SPINK2). In particular, the invention provides new molecules based on a T-cell receptor (TCR), which are selective and specific for the tumor-expressed antigen of the invention. The TCRs of the invention and SPINK2-binding fragments derived from this TCRs are useful in the diagnosis, treatment and prevention of cancer in which the SPINK2 antigen is expressed. Nucleic acids encoding antigen-recognizing structures according to the invention, vectors including these nucleic acids, recombinant cells expressing these antigen-recognizing structures, and pharmaceutical compositions comprising compounds of the invention are also provided.
