Extending the half-life of the anti-TfR1 NANOBODY®-ASO shuttles enhances heart, sciatic nerve, and brain exposure and enables up to 30-60% target knockdown in different CNS cell types are highlighted.
A novel monovalent TfR1-binding VHH-Fc is described for the delivery of oligonucleotide cargo, including antisense oligonucleotides (ASOs) and small interfering RNAs (siRNAs) across the BBB in rodents and non-human primates (NHPs), supporting the translational potential of the VHH-antisense RMT platform for the treatme...

The blood-brain barrier (BBB) presents a challenge for central nervous system (CNS) therapies. Receptor-mediated transcytosis offers a solution, but existing receptor targets are ubiquitous across CNS and peripheral tissues, causing unintended exposure. We identified carbonic anhydrase IV (CA-IV) as a brain-enriched re...

Effective treatment of brain diseases is limited by poor blood-brain barrier (BBB) penetration of drugs and their nanosized carriers. The intracellular transport of nanocarriers in brain microvessel endothelial cells (BMECs) significantly affects BBB-crossing efficiency. Most nanocarriers follow the lysosomal degra...

Glioblastoma (GBM) remains one of the most lethal and intractable central nervous system malignancies, characterized by aggressive cellular proliferation, profound hypoxia, and an immunosuppressive microenvironment. The primary pharmacokinetic obstacle for systemic interventions is the blood–brain barrier (BBB), which...

It is shown that co-administration of K16ApoE with therapeutic proteins can mediate high concentrations of this protein in brain tissue, which can yield significant substrate clearance and profound neurologic improvement and survival benefits in animal models of late-infantile neuronal ceroid lipofuscinosis (LINCL; CLN...

The concept of achieving sustained high brain exposure by combining BBB transport with enhanced brain retention with binding to blood–brain barrier (BBB) proteins for enhanced BBB permeability was shown to be broadly applicable.
