Article Synopsis
- The study focuses on specific clusters of CD8+ T cells, categorized as CD8-NOS2+COX2+ and CD8-NOS2-COX2+, which play a significant role in the immune response to tumors.
- These unique cellular environments affect the spatial structure of CD8+ T cell interactions within tumors and can influence patient outcomes.
- The findings suggest that existing treatments, like NOS inhibitors and NSAIDs, could potentially target these cellular neighborhoods to improve cancer therapy.
Nitric oxide (NO) and reactive nitrogen species (RNS) exert profound biological impacts dictated by their chemistry. Understanding their spatial distribution is essential for deciphering their roles in diverse biological processes. This review establishes a framework for the chemical biology of NO and RNS, exploring their dynamic reactions within the context of cancer.

Purpose: The aim of this study was to assess miRNA-21 expression in the tumor tissues of Brazilian patients with breast cancer who underwent NAC and its correlation with clinicopathological variables.
