Research Overview

Glioblastoma multiforme carries a mean survival under eight months, a figure largely unchanged for decades, and the blood-brain barrier keeps most modern immunotherapy from reaching these tumors at all.

This study introduced an actively targeted immunotherapeutic nanoconjugate designed to cross the barrier by LRP-1 receptor-mediated transcytosis — an antibody-free approach using immunopeptides rather than full antibodies. The design aims to deliver immune-modulating activity into the central nervous system, addressing the delivery problem that has limited immunotherapy against brain tumors.

Key Discoveries

  • Antibody-free immunopeptide nanoconjugate designed to cross the blood-brain barrier
  • Uses LRP-1 receptor-mediated transcytosis for active brain targeting
  • Targets glioblastoma, where mean survival has stayed under 8 months for decades
