Limited drug accumulation and an immunosuppressive microenvironment are the major bottlenecks in the treatment of glioblastoma multiforme (GBM). Herein, we report a copper-coordination driven brain-targeting nanoassembly (TCe6@Cu/TP5 NPs) for site-specific delivery of therapeutic agents and efficient immunotherapy by activating the cGAS-STING pathway and downregulating the expression of PD-L1. To achieve this, the mitochondria-targeting triphenylphosphorus (TPP) was linked to photosensitizer Chlorin e6 (Ce6) to form TPP-Ce6 (TCe6), which was then self-assembled with copper ions and thymopentin (TP5) to obtain TCe6@Cu/TP5 NPs.

Intractable infected wound caused by drug-resistant bacteria remains a severe healthcare problem. Reactive oxygen species (ROS)-based nanocatalytic therapy (ROS-NT) is harnessed to combat drug-resistant bacterial infection. However, it can also cause immune imbalance and excessive inflammatory responses, postponing subsequent wound healing process.

Background: Serine/glycine are critical for the growth and survival of cancer cells. Some cancer cells are more dependent on exogenous serine/glycine than endogenously synthesized serine/glycine. However, the function and underlying mechanisms of exogenous serine/glycine in renal cell carcinoma (RCC) remain unclear.

Human induced pluripotent stem cell (iPSC)-derived endothelial cells (ECs) have emerged as a promising source of autologous cells with great potential to produce novel cell therapy for ischemic vascular diseases. However, their clinical application still faces numerous challenges including safety concerns such as the potential aberrant immunogenicity derived from the reprogramming process. This study investigated immunological phenotypes of iPSC-ECs by a side-by-side comparison with primary human umbilical vein ECs (HUVECs).

The mitochondrial genome (mtDNA) is an important source of inherited extranuclear variation. Clonal increases in mtDNA mutation heteroplasmy have been implicated in aging and disease, although the impact of this shift on cell function is challenging to assess. Reprogramming to pluripotency affects mtDNA mutation heteroplasmy.
