概括
尽管有理论预测,但女性在黄体阶段不会表现出增加的厌恶或免疫反应. 孕激素水平与增加的疾病回避或分泌IgA (sIgA) 反应无关.
科学领域:
- 生殖免疫学 生殖免疫学
- 行为内分泌学行为内分泌学.
- 易受感染性疾病的易感性
背景情况:
- 由于孕激素的免疫抑制作用,女性在黄体期可能更容易感染感染.
- 这种免疫抑制,虽然有助于怀孕,但可能会增加对病原体的脆弱性.
- 理论上的补偿机制包括增加的厌恶和回避行为,以及像分泌IgA (sIgA) 这样的免疫反应.
研究的目的:
- 调查在不同月经周期阶段和使用荷尔蒙避孕的妇女对疾病线索的主动免疫和行为反应.
- 为了确定孕激素诱导的免疫抑制是否被增加的厌恶或sIgA水平所抵消.
主要方法:
- 对比的是61名具有自然月经周期的妇女 (卵泡相对于质阶段) 和20名服用荷尔蒙避孕药的妇女.
- 评估疾病脆弱性,厌恶和对与疾病相关的视频刺激的反应.
- 测量了唾液激素水平和分泌IgA (sIgA) 度.
主要成果:
- 在HC的女性报告了比自然骑自行车的女性更高的疾病脆弱性.
- 对疾病线索的厌恶和sIgA反应在不同组中是相似的,不管孕激素水平如何.
- 在自然循环女性中,在孕激素和基线sIgA之间观察到U形关系,在排卵期间出现下降.
结论:
- 数据不支持孕激素诱导的免疫抑制和增强的厌恶或主动的sIgA反应之间的补偿关系.
- 荷尔蒙避孕药,而不是黄体期的孕激素,与感知到疾病脆弱性的增加有关.
- 对疾病线索的积极免疫和行为反应似乎独立于黄质阶段的孕激素水平.

Target Cell Response to Hormones
3.0K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Factors Affecting the Risk of Infection
11.8K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Major Hormones and Their Functions
387
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Background and Environment Affect Phenotype
6.5K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Hormones of the Adrenal Glands
2.4K
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

Psychoneuroimmunology: Cardiovascular Disease
30
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...
