Exosomes, naturally derived nanovesicles secreted from various cell types, can serve as an effective platform for the delivery of various cargoes, because of their intrinsic ability such as long blood circulation and immune escapinge. However, unlike conventional synthetic nanoparticles, drug release from exosomes at defined targets is not controllable. Moreover, endowing exosomes with satisfactory cancer‐targeting ability is highly challenging. Here, for the first time, a biological and synthetic hybrid designer exosome is described with photoresponsive functionalities based on a donor cell‐assisted membrane modification strategy. Practically, the designer exosome effectively accumulates at target tumor sites via dual ligand‐mediated endocytosis. Then the localized hyperthermia induced by the conjunct gold nanorods under near‐infrared irradiation impacts the permeability of exosome membrane to enhance drug release from exosomes, thus inhibiting tumor relapse in a programmable manner. The designer exosome combines the merits of both synthetic materials and the natural nanovesicles. It not only preserves the intrinsic functionalities of native exosome, but also gains multiple abilities for efficient tumor targeting, controlled release, and thermal therapy like synthetic nanocarriers. The versatile designer exosome can provide functional platforms by engineering with more multifarious functionalities from synthetic materials to achieve individualized precise cancer therapy in the future.

主动靶向化学-光热协同肿瘤治疗的设计外泌体

外来体是从各种细胞类型分泌的天然来源的纳米囊泡,由于其固有的能力,例如长血液循环和免疫逃逸,可以用作递送各种货物的有效平台。但是,与常规的合成纳米颗粒不同,药物无法从外来体在确定的靶标处释放。此外,赋予外来体以令人满意的癌症靶向能力是非常具有挑战性的。在这里,这是首次使用基于供体细胞辅助膜修饰策略的具有光响应功能的生物和合成杂交设计器外泌体。实际上,设计者的外泌体通过双重配体介导的内吞作用有效地聚集在靶肿瘤部位。然后,金纳米棒在近红外辐射下引起的局部热疗影响外泌体膜的通透性,以增强药物从外泌体的释放,从而以可编程的方式抑制肿瘤复发。设计师的外泌体结合了合成材料和天然纳米囊泡的优点。它不仅保留了天然外来体的内在功能,而且还获得了多种能力,可以有效地靶向肿瘤,控制释放以及像合成纳米载体一样进行热疗。多功能的设计人员囊泡可以通过工程技术提供功能平台,这些功能包括合成材料提供的更多功能,从而在将来实现个性化的精确癌症治疗。从而以可编程的方式抑制肿瘤复发。设计师的外泌体结合了合成材料和天然纳米囊泡的优点。它不仅保留了天然外来体的内在功能,而且还获得了多种能力,可以有效地靶向肿瘤,控制释放以及像合成纳米载体一样进行热疗。多功能的设计人员囊泡可以通过工程技术提供功能平台,这些功能包括合成材料提供的更多功能,从而在将来实现个性化的精确癌症治疗。从而以可编程的方式抑制肿瘤复发。设计师的外泌体结合了合成材料和天然纳米囊泡的优点。它不仅保留了天然外来体的内在功能,而且还获得了多种能力,可以有效地靶向肿瘤,控制释放以及像合成纳米载体一样进行热疗。多功能的设计人员囊泡可以通过工程技术提供功能平台,这些功能包括合成材料提供的更多功能,从而在将来实现个性化的精确癌症治疗。和热疗法,如合成纳米载体。多功能的设计人员囊泡可以通过工程技术提供功能平台,这些功能包括合成材料提供的更多功能,从而在将来实现个性化的精确癌症治疗。和热疗法,如合成纳米载体。多功能的设计人员囊泡可以通过工程技术提供功能平台,这些功能包括合成材料提供的更多功能,从而在将来实现个性化的精确癌症治疗。
