Cancer Immunotherapy
In article number 2308731, Bing Liu, Chun Xu, Lin‐Lin Bu, and co‐workers explore the innovative use of nanoparticles for targeted drug delivery to lymph nodes, aiming to activate the immune system in the battle against cancer. The image interprets the physiological process of nanoparticles targeting lymph nodes for drug delivery as an approach in immunotherapy.
Immunotherapy has emerged as a potent strategy in cancer treatment, with many approved drugs and modalities in the development stages. Despite its promise, immunotherapy is not without its limitations, including side effects and suboptimal efficacy. Using nanoparticles (NPs) as delivery vehicles to target immunotherapy to lymph nodes (LNs) can improve the efficacy of immunotherapy drugs and reduce...
Gene therapy (GT) and photothermal therapy (PTT) have emerged as promising alternatives to chemotherapy and radiotherapy for cancer treatment, offering noninvasiveness and reduced side effects. However, their efficacy as standalone treatments is limited. GT exhibits slow response rates, while PTT is confined to local tumor ablation. The convergence of GT and PTT, known as GT‐PTT, facilitated by photothermal...
Neuroblastoma Therapy
In article number 2201671, Zhen Liu and co‐workers construct polysialic acid‐targeting nano‐missiles via a molecular imprinting strategy using oligosialic acid containing 4‐7 units digested from polySia as the template. Effective targeted photothermal therapy of neuroblastoma is achieved using nano‐missiles loaded with the near‐infrared fluorescent reactive dye indocyanine green...
Exploring new targets and developing novel targeted therapies are urgently needed for neuroblastoma therapy. Polysialic acid (polySia), a linear homopolymer of sialic acid units that correlates well with tumor progression and poor prognosis, has emerged as a potential target for neuroblastoma. However, the lack of polySia‐specific binding reagents has severely limited the development of polySia‐targeting...
Photothermal therapy (PTT) has attracted tremendous attention due to its noninvasiveness and localized treatment advantages. However, heat shock proteins (HSPs) associated self‐preservation mechanisms bestow cancer cells thermoresistance to protect them from the damage of PTT. To minimize the thermoresistance of cancer cells and improve the efficacy of PTT, an integrated on‐demand nanoplatform composed...
In cells, mechanical forces play a key role in impacting cell behaviors, including adhesion, differentiation, migration, and death. Herein, a 20 nm mitochondria‐targeted zinc‐doped iron oxide nanocube is designed as a nanospinner to exert mechanical forces under a rotating magnetic field (RMF) at 15 Hz and 40 mT to fight against cancer. The nanospinners can efficiently target the mitochondria of cancer...
Self‐propelled Au‐BP7@SP Janus‐like nanohybrids with active motion under NIR laser can effectively enhance the temperature of tumors, potentially by converting the kinetic energy into thermal energy, enhancing photothermal tumor therapy. On page 5423, Y.‐S. Li, L. Wang, H. Wang, and co‐workers provide an insight into nanohybrids' effect on photothermal treatment and open a new avenue to cancer treatment...
Au‐BP7@SP nanohybrids with active motion under NIR laser irradiation can effectively enhance the temperature of tumor potentially by converting the kinetic energy to thermal energy, enhancing the killing efficiency of the tumor cells compared with Au@SP. The study provides an insight of nanohybrids' effect on photothermal treatment and opens a new avenue to cancer treatment by using self‐propulsion...
Combining photothermal therapy (PTT) with clinical technology to kill cancer via overcoming the low tumor targeting and poor therapy efficiency has great potential in basic and clinical researches. A brand‐new MoS2 nanostructure is designed and fabricated, i.e., layered MoS2 hollow spheres (LMHSs) with strong absorption in near‐infrared region (NIR) and high photothermal conversion efficiency via...
