Targeted Degradation Technology Based on the Autophagy-Lysosomal Pathway: A Promising Strategy for Treating...

In recent years, targeted protein degradation (TPD) strategies leveraging the autophagy-lysosomal pathway (ALP) have transcended the limitations of conventional drug molecules, emerging as a highly promising approach for selectively eliminating disease-related proteins via the cell's intrinsic degradation machinery. These TPD methods, such as autophagosome-tethering compounds (ATTEC), autophagy-targeting chimera (AUTAC), AUTOphagy-TArgeting chimera (AUTOTAC), and chaperone-mediated autophagy (CMA) targeting chimera, exhibit efficacy in degrading misfolded protein aggregates associated with neurodegenerative disorders. Moreover, the excessive accumulation of misfolded proteins or protein complexes in the placenta has been identified as a significant contributor to preeclampsia (PE). Given the lack of effective treatments for PE, the application of autophagy-mediated TPD technology presents a novel therapeutic avenue. This review draws parallels between misfolded protein aggregates in neurodegenerative diseases and placenta-derived PE, integrating a substantial number of full-text studies. By harnessing TPD technologies grounded in the ALP, these autophagic degraders offer a pioneering approach for targeted therapy in PE by dismantling potential targets. Presently, there is limited exploration of ALP technology for identifying target proteins in the placenta. Nonetheless, we have proposed several potential target proteins, laying the groundwork for future therapeutic endeavors.
