Title:
METHOD FOR PREPARING TUMOR ANTIGEN-RESPONSIVE LIVING CELLULAR NANO BACKPACKS AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/104137
Kind Code:
A1
Abstract:
Disclosed are a method for preparing tumor antigen-responsive living cellular nano backpacks and the use thereof. The loading of immune lymphocyte to reduction-responsive albumin nano backpacks is achieved by means of bio-orthogonal coupling, and antigen-responsive controlled-release living cellular nano backpacks (LCNBs) are obtained. The immune lymphocyte is stimulated by a tumor antigen, which leads to an increase in the reduction potential level of the cell surface, thereby triggering the fixed-point reduction-responsive release of albumin nano backpacks. The released nano backpacks can activate immune lymphocyte in situ at a tumor lesion, feedback enhance the anti-tumor effect of immune lymphocyte, achieve efficient and synergistic tumor immunotherapy, and enhance the safety and bioavailability of the free drug in vivo.
