NIR‐Activatable Heterostructured Nanoadjuvant CoP/NiCoP Executing Lactate Metabolism Interventions for Boosted Photocatalytic Hydrogen Therapy and Photoimmunotherapy

Advanced Materials, Год журнала: 2023, Номер 36(5)

Опубликована: Ноя. 2, 2023

Near-infrared (NIR) laser-induced photoimmunotherapy has aroused great interest due to its intrinsic noninvasiveness and spatiotemporal precision, while immune evasion evoked by lactic acid (LA) accumulation severely limits clinical outcomes. Although several metabolic interventions have been devoted ameliorate immunosuppression, intracellular residual LA still remains a potential energy source for oncocyte proliferation. Herein, an immunomodulatory nanoadjuvant based on yolk-shell CoP/NiCoP (CNCP) heterostructure loaded with the monocarboxylate transporter 4 inhibitor fluvastatin sodium (Flu) is constructed concurrently relieve immunosuppression elicit robust antitumor immunity. Under NIR irradiation, CNCP heterojunctions exhibit superior photothermal performance photocatalytic production of reactive oxygen species hydrogen. The continuous heat then facilitates Flu release restrain exudation from tumor cells, whereas cumulative can be depleted as hole scavenger improve efficiency. Subsequently, potentiated therapy not only initiate systematic immunoreaction, but also provoke severe mitochondrial dysfunction disrupt supply shock protein synthesis, in turn realizing mild therapy. Consequently, remodeling endows intensive cascade treatment optimal safety profile effectually suppress proliferation metastasis, which offers new paradigm development metabolism-regulated immunotherapy.

Injectable Nano-in-Gel Vaccine for Spatial and Temporal Control of Vaccine Kinetics and Breast Cancer Postsurgical Therapy

ACS Nano, Год журнала: 2024, Номер 18(4), С. 3087 - 3100

Опубликована: Янв. 18, 2024

Breast cancer is the most commonly diagnosed cancer, and surgical resection first choice for its treatment. With development of operation techniques, treatment breast evolving toward minimally invasive breast-conserving approaches. However, surgery prone to an increased risk recurrence becoming a key challenge that needs be solved. In this study, we introduce one-shot injectable nano-in-gel vaccine (NIGel-Vax) postoperative therapy. The NIGel-Vax was constructed by mixing protein antigens with PEI-4BImi-Man adjuvant then encapsulated in hydrogel made oxidized dextran (ODEX) 4-arm PEG-ONH2. Using 4T1 tumor-extracted proteins as antigen, achieved 92% tumor suppression rate 33% cure therapy model. tumor-associated antigen trophoblast cell-surface 2 (TROP2) 96% 50% triple-negative (TNBC) models. This design provides encouraging approach management.
