Moreover, fluorescent chemosensors in the NIR window offer advantages such as high signal-to-noise ratio, low tissue damage, and deep tissue penetration. The combination of the advantages of ratiometric fluorescent probes and single-intensity-based NIR probes in NIR ratiometric fluorescent probes has led to their widespread application in biomedical research and clinical practice. This review provides a systematic summary of the recent advances (2020-2022) in this field, discussing the design strategies, sensing mechanisms, and bioapplications of these intelligent fluorescent probes. The challenges and prospects in this promising field are also addressed, with the anticipation that this work will inspire the development of organic NIR ratiometric fluorescent probes.

T-Cell-Derived Nanovesicles for Cancer Immunotherapy

Jihye Hong et al.

Summary: While T-cell therapy is a significant breakthrough in cancer immunotherapy, its efficacy against solid tumors is limited due to T-cell exhaustion caused by immunosuppressive mechanisms. T-cell-derived nanovesicles (TCNVs) produced by extrusion through membranes with micro/nanosized pores show promising anti-tumoral activity in the immunosuppressive tumor microenvironment. TCNVs express programmed cell death protein 1 and TGF-beta receptor on their surface, which helps block PD-L1 on cancer cells and scavenge TGF-beta in the TME, preventing T-cell exhaustion and directly killing cancer cells. These findings suggest TCNVs as an effective strategy for cancer immunotherapy to overcome tumor's immunosuppressive mechanisms.
