The inhibitory effects of nimotuzumab on CD276 expression and immune escape in head and neck squamous cell carcinoma: Insights into anticancer mechanisms.

CD276 has been identified as a novel immune checkpoint, and its overexpression is associated with immune evasion and poor prognosis in various tumors, including head and neck squamous cell carcinoma (HNSCC). Nimotuzumab, a humanized anti-epidermal growth factor receptor (EGFR) monoclonal antibody, has been approved for various solid tumors. However, it remains unclear whether its anticancer efficacy involves a reduction in CD276 expression.

Doxorubicin prodrug for γ-glutamyl transpeptidase imaging and on-demand cancer therapy.

The γ-glutamyl transpeptidase (γ-GGT) is an important tumor marker, which has been reported to be firmly associated with the developmental stage of liver cancer. Therefore, it makes sense to image and monitor γ-GGT level and design γ-GGT-responsive prodrug for integrated diagnosis and treatment of liver cancer. Herein, we prepare a doxorubicin (Dox) prodrug for imaging γ-GGT and on-demand treating liver cancer.

Protein serine/threonine phosphatases in tumor microenvironment: a vital player and a promising therapeutic target.

The tumor microenvironment (TME) is involved in cancer initiation and progression. With advances in the TME field, numerous therapeutic approaches, such as antiangiogenic treatment and immune checkpoint inhibitors, have been inspired and developed. Nevertheless, the sophisticated regulatory effects on the biological balance of the TME remain unclear.

Symmetry Breaking of FeN4 Moiety via Edge Defects for Acidic Oxygen Reduction Reaction.

Fe-N-C catalysts, with a planar D4h symmetric FeN4 structure, show promising as noble metal-free oxygen reduction reaction catalysts. Nonetheless, the highly symmetric structure restricts the effective manipulation of its geometric and electronic structures, impeding further enhancements in oxygen reduction reaction performance. Here, a high proportion of asymmetric edge-carbon was successfully introduced into Fe-N-C catalysts through morphology engineering, enabling the precise modulation of the FeN4 active site.

The Role of Extracellular Vesicles in the Development and Treatment of Psoriasis: Narrative Review.

Psoriasis is a chronic inflammatory polygenic disease with significant impacts on skin and joints, leading to substantial treatment challenges and healthcare costs. The quest for novel therapeutic avenues has recently highlighted extracellular vesicles (EVs) due to their potential as biomarkers and therapeutic agents in autoimmune diseases, including psoriasis. EVs are nano-sized, lipid membrane-bound particles secreted by cells that have emerged as promising tools for targeted drug delivery, owing to their unique structure.
