Paclitaxel/Luteolin Coloaded Dual-Functional Liposomes for Esophageal Cancer Therapy.

Combination therapy integrating chemotherapeutic agents with natural bioactive ingredients represents an attractive strategy for esophageal squamous cell carcinoma (ESCC) treatment, yet achieving tumor-specific co-delivery remains a critical challenge. Herein, we report that the combination of luteolin (LUT) and paclitaxel (PTX) exerts a remarkable synergy in ESCC treatment, while concurrently alleviating PTX-induced hepatotoxicity; EA2 aptamer has been identified for its exceptional specificity and strong affinity toward Catenin Alpha 1 protein (CTNNA1) in ESCC cells. Leveraging this specificity, nanosized EA2-modified pH-sensitive liposomes (EA2-PSL-PTX/LUT) are successfully developed with effective co-loading, controlled release, and good biostability.

Lycium barbarum oligosaccharide-derived carbon quantum dots inhibit glial scar formation while promoting neuronal differentiation of neural stem cells.
