Abstract

Background

Cytokines, known for their pro- and anti-inflammatory roles, are also key regulators of sleep–wake cycles. Classical pro-inflammatory cytokines, such as interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-α), are associated with increased sleep, particularly slow-wave sleep (SWS), while anti-inflammatory cytokines, like interleukin-10 (IL-10), generally reduce sleep duration. Given the essential role of sleep in memory consolidation, this study aimed to investigate whether interleukin-12 (IL-12), a pro-inflammatory cytokine, could increase sleep duration following a memory acquisition task and subsequently improve memory performance. Male Swiss mice were surgically implanted with electrodes for electrocorticogram (ECoG) and electromyogram (EMG) recordings to track their sleep–wake cycles. After a recovery period, baseline sleep–wake activity was recorded. The mice were then randomly assigned to two groups and treated with either IL-12 (0.5 µg, i.p.) or a phosphate-buffered saline (PBS, i.p.) control, administered immediately before the multiple-trial inhibitory avoidance (MTIA) task, a behavioral test used to assess memory performance. Following the memory acquisition session, sleep–wake activity was immediately recorded for a continuous 24-h period.

Results

Mice treated with IL-12 exhibited longer latency to cross into the dark compartment during the MTIA test, indicating improved memory retention compared to the control group. Interestingly, this improved performance was associated with prolonged wakefulness, particularly in the first three hours after task acquisition.

Conclusion

The study shows that IL-12 can improve memory retention through prolonged wake episodes rather than increased sleep. This finding challenges the conventional understanding that sleep is the primary state for memory consolidation, suggesting that under specific conditions, wakefulness may also play a key role in supporting memory processes. Further research is needed to explore the underlying mechanisms of IL-12's cognitive effects.

白细胞介素-12 可调节睡眠-觉醒活动并提高记忆能力
背景细胞因子以其促炎和抗炎作用而闻名,也是睡眠-觉醒周期的关键调节因子。白细胞介素-1(IL-1)和肿瘤坏死因子-α(TNF-α)等典型的促炎细胞因子与睡眠,尤其是慢波睡眠(SWS)的增加有关,而白细胞介素-10(IL-10)等抗炎细胞因子通常会缩短睡眠时间。鉴于睡眠在记忆巩固中的重要作用,本研究旨在探讨白细胞介素-12(IL-12)这种促炎细胞因子是否能在记忆获取任务后延长睡眠时间,进而改善记忆表现。研究人员通过手术为雄性瑞士小鼠植入了电极,用于记录皮层电图(ECoG)和肌电图(EMG),以跟踪它们的睡眠-觉醒周期。经过一段恢复期后,记录基线睡眠-觉醒活动。然后将小鼠随机分配到两组,分别用IL-12(0.5微克,静注)或磷酸盐缓冲盐水(PBS,静注)对照组进行治疗,并在多试抑制性回避(MTIA)任务(一种用于评估记忆能力的行为测试)前立即给药。结果与对照组相比,接受IL-12治疗的小鼠在MTIA测试中跨入暗区的潜伏期更长,这表明小鼠的记忆保持能力有所提高。有趣的是,这种表现的改善与长时间的觉醒有关,尤其是在获得任务后的前三个小时。这一发现挑战了睡眠是巩固记忆的主要状态这一传统认识,表明在特定条件下,觉醒也可能在支持记忆过程中发挥关键作用。要探索IL-12对认知产生影响的潜在机制,还需要进一步的研究。
