组胺H1受体
外觀
H1受體是一種屬於視紫紅質樣G蛋白偶聯受體家族的受體,可被組織胺活化。它在平滑肌、血管內皮細胞、心臟、中樞神經系統中表現。H1受體與細胞內Gα蛋白的Gαq亞基連接,活化磷脂酶C和肌醇三磷酸(IP3)信號通路。作用於該受體的抗組織胺藥被用作抗過敏藥物。該受體的晶體結構已確定[6]並用於在基於結構的虛擬篩選研究中發現新的組織胺H1受體配體[7]
功能
[編輯]NF-κB(調節發炎過程的轉錄因子)的表現受到H1受體的固有活性以及與受體結合的促效劑的促進。[8]抗組織胺藥已被證明可以減弱NF-κB的表現並減輕相關細胞中的某些發炎過程。[8]
組織胺還可能在陰莖勃起中起作用。[9]
神經生物學
[編輯]組織胺H1受體被內源性組織胺活化,內源性組織胺是由下視丘結節乳狀體中的神經元釋放的。結節乳狀體的組織胺能神經元在「喚醒」周期中變得活躍,以大約2赫茲的頻率放電;而在慢波睡眠期間,該放電頻率降至大約0.5赫茲。[10]
結節乳狀體是一種組織胺能核,對調節睡眠-覺醒周期起重要作用。[11] 透過血腦屏障的H1拮抗劑可以抑制結節乳狀體投射的神經元上的H1受體的活性,這種作用可能是這些藥物造成嗜睡作用的原因。[來源請求]

The H1-receptor is a transmembrane protein belonging to the G-protein coupled receptor family. Signal transduction from the extracellular to the intracellular environment occurs as the GPCR becomes activated after binding of a specific ligand or agonist. A subunit of the G-protein subsequently dissociates and affects intracellular messaging including downstream signaling accomplished through various intermediaries such as cyclic AMP, cyclic GMP, calcium, and nuclear factor kappa B (NF-κB), a ubiquitous transcription factor thought to play an important role in immune-cell chemotaxis, proinflammatory cytokine production, expression of cell adhesion molecules, and other allergic and inflammatory conditions.1,8,12,30–32 ... For example, the H1-receptor promotes NF-κB in both a constitutive and agonist-dependent manner and all clinically available H1-antihistamines inhibit constitutive H1-receptor-mediated NF-κB production ...
Importantly, because antihistamines can theoretically behave as inverse agonists or neutral antagonists, they are more properly described as H1-antihistamines rather than H1-receptor antagonists.15 - ^ Cará AM, Lopes-Martins RA, Antunes E, Nahoum CR, De Nucci G.

Within the brain, histamine is synthesized exclusively by neurons with their cell bodies in the tuberomammillary nucleus (TMN) that lies within the posterior hypothalamus. There are approximately 64000 histaminergic neurons per side in humans. These cells project throughout the brain and spinal cord. Areas that receive especially dense projections include the cerebral cortex, hippocampus, neostriatum, nucleus accumbens, amygdala, and hypothalamus. ... While the best characterized function of the histamine system in the brain is regulation of sleep and arousal, histamine is also involved in learning and memory ... It also appears that histamine is involved in the regulation of feeding and energy balance.
