- 研究遗传因果关系对于理解疾病机制至关重要.
研究的目的:
- 通过使用遗传数据,探索自身免疫神经疾病和MD之间的潜在因果关系.
- 为了确定特定的自身免疫神经系统疾病 (多发性硬化症,光学神经炎,脑神经衰弱) 是否会因果地影响MDs (焦虑症,严重抑郁症,多动症,精神分裂症,双相情感障碍).
- 为了确定MD是否因果关系影响自身免疫神经系统疾病.
主要方法:

Autoimmune Disorders
677
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

Psychoneuroimmunology: Diabetes and Cancer
62
Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Psychoneuroimmunology: Cardiovascular Disease
78
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
