NIR-II light-driven nanovaccine for cancer immunotherapy via lymph node migration-mediated accumulation.

Tumor vaccines that combine tumor antigens with immune adjuvants offer a promising strategy for cancer immunotherapy. A particularly effective approach involves the generation of tumor antigens within the tumor microenvironment and their subsequent delivery to the lymph nodes alongside immune adjuvants. However, Co-delivery of antigen and adjuvant on a single nano-platform remains facing some key problems, such as a single nanomedicine cannot simultaneously achieve antigen production, capture, and delivery to lymph nodes, as well as leakage of adjuvant due to destruction of nano-drug by exogenous stimuli and failure to capture antigen effectively.

Role of Tunneling Nanotubes in Arachidonic Acid Transfer and Macrophage Function Reprogramming in Intrahepatic Cholangiocarcinoma.

Tumor-associated macrophages (TAMs) play a crucial role in tumor progression within the tumor microenvironment (TME) through phenotypic plasticity and functional modulation. While tunneling nanotubes (TNTs) mediate intercellular communication, their role in shaping TAMs phenotypes and function remains unclear. This study explores how TNTs facilitate the transfer of tumor-derived materials, particularly fatty acids, to TAMs, affecting macrophage polarization and function.

Short delay to initiate plasma exchange or immunoadsorption as synergistic therapies for patients in the acute phase of anti-NMDAR encephalitis.

Background: Combined first-line therapies have been frequently adopted for patients with anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis. Plasma exchange (PE) or immunoadsorption (IA) was used as an add-on option following initial immunotherapies, including high-dose steroids and intravenous immunoglobulin (IVIG). However, whether a shorter delay of PE or IA can improve the early recovery prognosis of patients with anti-NMDAR encephalitis remains largely unknown.

Capturing Hydrophilic Chemotherapeutics Agents Into siRNA-Encapsulated Vesicle-Like Nanoparticles for Convenient ICB-Chemo Combination Therapy.

Clinical evidence has demonstrated that combining immune checkpoint blockade (ICB) therapy with chemotherapy significantly improves response rates to ICB therapy and therapeutic efficacy in various tumor types. However, a convenient method for achieving synergistic ICB therapy and chemotherapy with precise co-delivery of both agents is still highly desirable. In this study, a strategy for co-delivering small interfering RNA (siRNA) encapsulated in vesicle-like nanoparticles (VNP) and chemotherapeutic drugs is aimed to develop.

Promoting the Recruitment, Engagement, and Reinvigoration of Effector T Cells via an Injectable Hydrogel with a Supramolecular Binding Capability for Cancer Immunotherapy.

T cells play a basic and key role in immunotherapy against solid tumors, and efficiently recruiting them into neoplastic foci and sustaining long-term effector function are consistent goals that remain a critical challenge. Here, an injectable alginate-based hydrogel with abundant β-cyclodextrin (ALG-βCD) sites is developed and intratumorally injected to recruit CCR9 CD8 T cells (a subset of T cells with robust antitumor activity) via the trapped chemokine CCL25. In the meantime, an intravenously injected adamantane-decorated anti-PD1 antibody (Ad-aPD1) would hitchhike on recruited CCR9 CD8 T cells to achieve the improved intratumoral accumulation of Ad-aPD1.
