【摘要】:腺苷,作為機體內(nèi)ATP代謝過程中的重要產(chǎn)物,通過激活腺苷受體(adenosine receptors,AR)(A1R、A2AR、A2BR、A3R)參與了機體的許多生理及病理過程的調(diào)節(jié)。腺苷受體在體內(nèi)的各個組織器官具有廣泛的分布,在免疫系統(tǒng)尤為豐富,如中性粒細胞、巨噬細胞、淋巴細胞、樹突狀細胞均有較高表達。炎癥,是機體抵御外來刺激的一種防御性免疫機制,過度的炎癥反應則會對機體造成損傷,中性粒細胞是其中重要的參與者之一,腺苷及其受體的調(diào)節(jié)密切參與了其黏附、遷移、細菌殺傷作用、炎癥介質(zhì)產(chǎn)生、凋亡等過程,從而對炎癥起到調(diào)節(jié)作用。
[Abstract]:Adenosine, as an important product of ATP metabolism, is involved in many physiological and pathological processes by activating adenosine receptor (adenosine receptors,AR). Adenosine receptors are widely distributed in various tissues and organs, especially in the immune system, such as neutrophils, macrophages, lymphocytes and dendritic cells. Inflammation is a defensive immune mechanism in which the body resists foreign stimuli. Excessive inflammatory reactions can damage the body. Neutrophils are one of the important participants, and the regulation of adenosine and its receptors is closely involved in its adhesion. Migration, killing of bacteria, production of inflammatory mediators, apoptosis and other processes, which play a role in the regulation of inflammation.
