Advancing pancreatic cancer therapy by mesothelin-specific nanobody conjugation.

ABSTRACT: Pancreatic adenocarcinoma (PAAD) is highly challenging to treat due to its poor prognosis and limited effective treatment options. Liposomal nanotechnology has emerged as a promising drug delivery platform in oncology, but existing liposomal therapies face limitations such as systemic toxicity, insufficient tumor selectivity, and low target specificity. Mesothelin (MSLN), an antigen overexpressed in PAAD, has attracted attention as a potential target for precision therapy. Here, we present the development of an anti-MSLN nanobody (D3 Nb) with high binding affinity (K_D = 2.2 nM) that can selectively bind to MSLN-positive cancer cells. Structural analysis revealed that hydrophobic and hydrogen bonds within the complementary determining region (CDR) of D3 Nb promote strong binding
