概括
意识地产生积极的期望可以通过激活大脑的奖励通路来增强免疫反应. 这项研究表明,人类的奖励中边活动和B型肝炎疫苗抗体水平之间存在联系.
科学领域:
- 神经免疫学 神经免疫学
- 神经科学是一个神经科学.
- 心理神经免疫学 心理神经免疫学
背景情况:
- 越来越多的证据表明大脑和身体之间存在神经生理学联系.
- 动物研究表明,多巴胺能中边路调节免疫功能.
- 在人类中存在类似的脑免疫联系,涉及有意识的积极期望,仍然未被探索.
研究的目的:
- 调查有意识的积极期望是否可以通过奖励中边路径调节人类免疫功能.
- 检查奖励中边路激活与乙型肝炎病毒 (HBV) 抗体水平在接种疫苗后之间的相关性.
- 评估使用fMRI神经反 (NF) 进行免疫调节的可行性.
主要方法:
- 一个双盲随机受控试验,涉及85名健康参与者.
- 参与者接受了fMRI神经反 (NF) 以调高奖励中边活动或对照区域,或没有接受NF.
- 在NF后,参与者接受了HBV疫苗,并评估了HBV抗体 (HBVab) 水平的变化.
主要成果:
- 两组NF都显示了奖励中边激活的显著增加.
- 大腹膜区域 (VTA) 的上调与疫苗接种后HBVab水平的增加相关 (r=0.31,P=0.018).
- 静脉动脉高调与涉及积极期望的心理策略相关;没有观察到抗体水平的显著群体差异.
结论:
- 意识地产生积极的期望可以激活奖励回路,以影响人类的免疫功能.
- 这种脑免疫相互作用,特别是VTA活动,显示出非侵入性免疫调节的潜力.
- 这些发现表明利用心理状态来增强免疫反应的途径,需要进一步调查.

Active versus Passive Immunity
10.1K
Immunity, along with the ability to limit pathogen growth to prevent significant body tissue damage, can be gained either by (1) actively developing an immune response within the individual after exposure to a pathogen or after getting vaccinated or (2) passively transferring immune components from an immune individual to one who is nonimmune. Both these forms of immunity can be found naturally and in medical practices.

Cells of the Adaptive Immune Response
8.5K
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

Immune Response Against Viral Pathogens
1.8K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
