Abstract

Biologics are an emerging class of medicines with substantial promise to treat neurological disorders such as Alzheimer's disease, stroke, and multiple sclerosis. However, the blood-brain barrier (BBB) presents a formidable obstacle that appreciably limits brain uptake and hence the therapeutic potential of biologics following intravenous administration. One promising strategy for overcoming the BBB to deliver biologics is the targeting of endogenous receptor-mediated transport (RMT) systems that employ vesicular trafficking to transport ligands across the BBB endothelium. If a biologic is modified with an appropriate targeting ligand, it can gain improved access to the brain via RMT. Various RMT-targeting strategies have been developed over the past 20 years, and this review explores exciting recent advances, emphasizing studies that show brain targeting in vivo.

  • Nanoparticle-based drug delivery systems exploit receptor-mediated transcytosis and adsorptive-mediated transcytosis to overcome blood-brain barrier challenges.

    “Nanoparticle-based drug delivery systems aim to overcome these challenges by exploiting specialized BBB transport mechanisms, primarily receptor-mediated transcytosis (RMT) and adsorptive-mediated transcytosis (AMT) [8, 9].”

    From Targeted Nanoparticles for Drug Delivery Across the Blood–Brain Barrier in Early and Late Stages of Alzheimer's Disease: A Review (2026) · cites this paper as [8]

    The Introduction’s “Targeting biologics to the brain via RMT” section describes liposomes and polymeric nanoparticles decorated with RMT-targeting ligands for brain delivery. Its “Receptor-mediated transport at the BBB” section also describes AMT, but discusses it for cationized proteins, not nanoparticle delivery, and cautions that it may not be an ideal drug-delivery target.

  • Adsorptive-mediated transcytosis is based on electrostatic interactions between positively charged nanoparticles and the negatively charged luminal surface of endothelial cell membranes.

    “AMT is based on electrostatic interactions between positively charged NPs and the negatively charged luminal surface of endothelial cell membranes, primarily due to the presence of heparan sulfate proteoglycans and other anionic residues [8].”

    From Targeted Nanoparticles for Drug Delivery Across the Blood–Brain Barrier in Early and Late Stages of Alzheimer's Disease: A Review (2026) · cites this paper as [8]

    The Introduction’s “Receptor-mediated transport at the BBB” section says adsorptive-mediated transport occurs when cationic serum proteins interact with negatively charged domains on the blood-facing endothelial membrane. It supports the charge-based mechanism, but does not establish that the interacting particles are nanoparticles or identify heparan sulfate proteoglycans and other anionic residues as the source of the negative charge. No page number is available in our copy. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
