An injectable, in situ forming and NIR-responsive hydrogel persistently reshaping tumor microenvironment for efficient melanoma therapy.

Background: Melanoma is a highly aggressive form of skin cancer with increasing incidence and mortality rates. Chemotherapy, the primary treatment for melanoma, is limited by hypoxia-induced drug resistance and suppressed immune response at the tumor site. Modulating the tumor microenvironment (TME) to alleviate hypoxia and enhance immune response has shown promise in improving chemotherapy outcomes.

Rapid Evaluation of Lung Adenocarcinoma Progression by Detecting Plasma Extracellular Vesicles with Lateral Flow Immunoassays.

Extracellular vesicles (EVs) have been widely used in liquid biopsy to diagnose and monitor cancers. However, since samples containing EVs are usually body fluids with complex components, the cumbersome separation steps for EVs during detection limit the clinical application and promotion of EV detection methods. In this study, a dyad lateral flow immunoassay (LFIA) strip for EV detection, containing CD9-CD81 and EpCAM-CD81, was developed to detect universal EVs and tumor-derived EVs, respectively.
