As the understanding of immune-related mechanisms in the development and progression of cancer advances, immunotherapies, notably Immune Checkpoint Inhibitors (ICIs), have become integral in comprehensive cancer treatment strategies. ICIs reactivate T-cell cytotoxicity against tumors by blocking immune suppressive signals on T cells, such as Programmed Death-1 (PD-1) and Cytotoxic T-lymphocyte Antigen-4 (CTLA-4). Despite their beneficial effects, ICIs are associated with immune-related adverse events (irAEs), manifesting as autoimmune side effects across various organ systems.

Selective labelling of the plasma membrane (PM) by fluorescence imaging techniques enables an intuitive analysis of cell status together with dynamic changes, and therefore is of great value. We herein disclose a novel carbazole-based probe, CPPPy, that shows aggregation-induced emission (AIE) property and is observed to selectively accumulate at the PM of living cells. Benefiting from its good biocompatibility and PM-targeted specificity, CPPPy can light up the PM of cells by high-resolution imaging even at a low concentration of 200 nM.

Astrocytes serve as an important supporting cell modulating glutamatergic synaptic transmission. Here, we found that peripheral spared nerve injury (SNI) induced astrocyte activation to release IL-6 in BLA.

Herein we show the construction of a type of isoquinoline-fused porphyrins and with an impressive NIR-absorbing capacity. In light of the extraordinary singlet oxygen generation capabilities of upon NIR irradiation, the representative nanoparticles () assembled show excellent tumoricidal behavior with good biocompatibility in the phototherapeutic window (650-850 nm).
