- 慢性疼痛和PTSD共享与与压力相关的表观遗传调节有关的脆弱性机制.
- FKBP5 (FK506结合蛋白5) 对于应激反应至关重要,并与PTSD和慢性疼痛有关.
- 关键的FKBP5转录FKBP51正在成为慢性疼痛脆弱性的驱动因素.
研究的目的:
- 调查FKBP51在压力诱导的对持续疼痛的脆弱性中的作用.
- 探索表观遗传机制,特别是DNA甲基化,是这种脆弱性的基础.
- 评估FKBP51抑制在减轻压力诱导的慢性疼痛中的治疗潜力.
主要方法:
- 在雄性和雌性小鼠中,亚慢性应激暴露.
- 在小鼠中Fkbp5的全球删除.
- 对脊髓组织进行表观遗传修饰 (DNA甲基化) 和基因表达的分析.
- 在应激暴露期间,雄性小鼠对FKBP51的药理抑制.
主要成果:
- 亚慢性压力加剧了由炎症引起的疼痛和焦虑,Fkbp5删除提供了保护,在男性中更为如此.
- 在雄性小鼠中,压力诱导了Fkbp5促进子和其他与压力相关的基因的低甲基化,但没有显著改变基因表达.
- 压力期间的FKBP51抑制减少了炎症性疼痛的持续时间,并逆转了一些压力诱导的DNA甲基化变化,但不是Fkbp5本身.
结论:

NF-κB-dependent Signaling Pathway
9.8K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Analgesia and Pain Management
1.5K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Epigenetic Regulation
3.7K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Stress and Mental Health
810
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

Chronic Pancreatitis I: Introduction
670
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
