主要成果:

过度炼导致小鼠的认知缺陷,其特征是炎症性细胞因子 (TNF-α,IL-6,IL-1β) 的增加和单碳酸盐载体4 (MCT4) 表达的减少.
狄克洛菲纳克治疗逆转了认知障碍,并使IL-6,IL-1β和MCT4的表达正常化.
这些发现表明,在过度炼的背景下,炎症,MCT4和认知功能之间存在联系.

结论:

单碳酸盐载体4 (MCT4) 与过度运动引起的认知障碍有关.
针对炎症和MCT4可能提供治疗策略,以减轻过度炼的负面认知影响.

Role of Hippocampus in Memory

Role of Hippocampus in Memory

The hippocampus, a critical brain structure, plays an essential role in memory processing, particularly in the formation and retrieval of memory. This small, seahorse-shaped region is located within the medial temporal lobe, with one hippocampus in each brain hemisphere. Experimental studies involving lesions in the hippocampi of rats have demonstrated significant impairments in tasks such as object recognition and maze navigation, indicating the hippocampus involvement in both recognition and...
