A nanoadjuvant that dynamically coordinates innate immune stimuli activation enhances cancer immunotherapy and reduces immune cell exhaustion

Seung Mo Jin et al.

Summary: In this study, a kinetically activating nanoadjuvant (K-nanoadjuvant) is proposed to integrate two waves of innate immune stimuli, resulting in effective antitumour immunity without immune cell exhaustion. The combinatorial code of K-nanoadjuvant is optimized in terms of the order, duration, and time window between activating Toll-like receptor 7/8 agonist and other Toll-like receptor agonists. K-nanoadjuvant induces effector/non-exhausted dendritic cells, CD8(+) T cells, and natural killer cells, leading to strong antitumour immunity with minimal toxicity when used as a monotherapy or in combination therapy with other treatments.

Nanoparticle-induced ferroptosis: detection methods, mechanisms and applications

Huizhen Zheng et al.

Summary: The combination of nanotechnology with ferroptosis for the treatment of severe diseases has attracted substantial research interest. However, differentiating nanoparticle-induced ferroptosis from other types of cell deaths, elucidating detailed mechanisms, and exploring the key properties of nanoparticles are challenging. Understanding the molecular events and physicochemical properties of nano-inducers involved in ferroptosis is crucial for designing effective nanomaterials for deliberate modulation of ferroptosis.
