Zusammenfassung: | The present invention relates to an aptamer penetrating the blood-brain barrier (BBB) to enable receptor-mediated transcytosis, and a use thereof. The aptamer of the present invention selectively targets transferrin receptor proteins only, rapidly passes through BBB by means of receptor-mediated transcytosis, can effectively transport and deliver various therapeutic agents such as proteins, antibodies, nucleic acids and low molecular weight compounds through simple chemical bonds, exhibits interspecific cross-reactivity in transferrin receptors, and is easily chemically modified, thereby being applicable as a drug carrier for nervous system diseases, especially brain and central nervous system diseases.
본 발명은 혈액-뇌 장벽(Blood-brain barrier, BBB)에 침투하여 수용체 매개성 내재화(receptor-mediated transcytosis)가 가능한 압타머 및 이의 이용에 관한 것이다. 본 발명의 압타머는 트랜스페린 수용체(Transferrin receptor) 단백질만을 선택적으로 타겟팅하고, 수용체 매개 세포 내재화를 통해 BBB를 빠르게 통과하고, 단순한 화학적 결합을 통해 단백질, 항체, 핵산 및 저분자 화합물 등 다양한 치료제를 효율적으로 수송 및 전달할 수 있으며, 종 간 트랜스페린 수용체에서 교차 반응을 나타내며, 화학적 변형이 쉬운 바, 신경계 질환, 특히 뇌 및 중추 신경계 질환에서 약물 전달체로 적용할 수 있다. |
