神经内分泌系统和免疫系统之间的相互作用有助于维持健康。一种相互作用涉及上级颈神经节(SCG),其调节由下颌下腺(SMG)产生的激素原下颌下腺大鼠1(SMR 1)。源自SMR 1的肽feG具有抗炎活性,对D-异构体feG进行修饰可增强生物活性。我们使用由OVA或巴西日本圆线虫(Nb)致敏的大鼠测试feG作为气道炎症的治疗剂。在24 h时,用feG而非fdG处理可下调OVA激发诱导的支气管肺泡灌洗(BAL)源性巨噬细胞、嗜酸性粒细胞和PMN(中性粒细胞)分别增加44%、69%和67%。 我们发现,在OVA激发后,feG还使BAL源性巨噬细胞和嗜酸性粒细胞上的ICAM-1减少了27%和65%,PMN上的L-选择素减少了55%。此外,feG而非fdG降低了BAL液中OVA诱导的TNF增加。我们发现,feG还下调了对乙酰甲胆碱的高反应性(27%)和肺实质中的微肉芽肿形成。在Nb激发大鼠中,feG处理可抑制离体过敏原诱导的气管平滑肌收缩高达73%。总之,feG是一种源自大鼠唾液腺激素原的肽的模拟物,在Brown-Norway大鼠的过敏性气道炎症中具有抗炎特性。SCG‐SMG神经内分泌通路在过敏性哮喘和其他炎症性疾病中的作用需要进一步研究。
Interactions between the neuro‐endocrine system and immune system help maintain health. One interaction involves the superior cervical ganglia (SCG), which regulate the prohormone submandibular rat 1 (SMR1) produced by the submandibular gland (SMG). A peptide derived from SMR1, feG, has anti‐inflammatory activity, and modification to D‐isomer feG enhances bioactivity. We tested feG as a therapeutic agent for airways inflammation, using rats sensitized by OVA or Nippostrongylus brasiliensis (Nb). Treatment with feG but not fdG down‐regulated OVA‐challenge‐induced increases in bronchoalveolar lavage (BAL)‐derived macrophages, eosinophils and PMN (neutrophils) by 44%, 69% and 67%, respectively, at 24 h. We found that feG also reduced ICAM‐1 on BAL‐derived macrophages and eosinophils by 27% and 65%, and L‐selectin on PMN by 55% following OVA challenge. Furthermore, feG but not fdG reduced the OVA‐induced TNF increase in BAL fluid. We showed that feG also down‐regulated both hyper‐responsiveness to methacholine (by 27%) and microgranulomata formation in the lung parenchyma. In Nb‐challenged rats, feG treatment inhibited ex vivo allergen‐induced contraction of tracheal smooth muscle by up to 73%. In conclusion, feG, which is a mimetic of a peptide derived from a rat salivary gland prohormone, has anti‐inflammatory properties in allergic airways inflammation in Brown‐Norway rats. The role of the SCG‐SMG neuro‐endocrine pathway in allergic asthma and other inflammatory diseases requires additional study.
