Bisphenol A(BPA)is an environmental endocrine disruptor commonly found in industri-al products such as plastics,resin coatings,and paper coatings,and it poses potential reproductive hazards.Despite extensive research,studies examining its effects on the F1 generation of rabbits are limited.This study established a BPA exposure model in pregnant female rabbits to investigate its impact on reproductive hormones,apoptosis,oxidative stress,inflammatory responses,and tissue integrity in weaned female offspring.The results indicate that BPA exposure induces oxidative stress and inflammation in F1 rabbits,disrupts hormonal balance,and affects antioxidant enzymes and inflammatory mediators through the modulation of the Nrf2 and NF-κB signaling pathways,ultimately leading to apoptosis and tissue damage.

Spinal cord injury (SCI) represents a complex pathophysiological process involving the interaction of multiple cell types. Conventional sequencing methods can only detect the average gene expression level of the damaged local cell populations, which is difficult to reflect its heterogeneity. Therefore, new technologies are needed to reveal the intercellular heterogeneity and the complex intercellular interactions of the damaged lesions. The single-cell RNA sequencing (scRNA-seq) technique facilitates high-resolution profiling of gene expression at the single-cell level, providing insights into cellular heterogeneity and function, potential molecular pathways, cell fate transitions, and the intercellular interactions pertinent to disease progression. This technology generates valuable gene expression data that support both basic and translational research efforts aiming at the identification of therapeutic targets for intervention. The scRNA-seq technique and its multifaceted application in the local immune microenvironment of injury after SCI were discussed, which will contribute to a more comprehensive understanding of the pathophysiological processes in the immune microenvironment of SCI.
