The LRP1-Mediated Endosomal Escape Enhancement Strategy proposes that therapeutic antibody delivery to the CNS can be optimized by targeting the low-density lipoprotein receptor-related protein 1 (LRP1) pathway while simultaneously engineering antibodies with pH-responsive endosomal escape mechanisms. Unlike FcRn-dependent transport which relies on passive transcytosis, this approach leverages LRP1's high-capacity apolipoprotein E (APOE)-mediated endocytic pathway at the blood-brain barrier. The
This hypothesis proposes engineering therapeutic antibodies with dual functionality: LDLR-binding domains for CNS penetration coupled to anti-inflammatory payloads targeting glial NF-κB signaling. The strategy leverages LDLR's well-characterized transcytotic properties at the blood-brain barrier to deliver antibodies that specifically suppress microglial and astrocytic inflammatory programs. Upon crossing the BBB via LDLR-mediated transport, these engineered antibodies would target key inflammat
