皮质类固醇通过抑制Hif-1α-糖解-乳酸轴和蛋白质乳酸化来控制喘. 这一发现为eosinophilic喘提供了新的治疗策略,这是目前没有治愈的疾病.
科学领域:
- 生物化学 生物化学
- 免疫学 免疫学 免疫学
- 代谢途径 代谢途径
背景情况:
- 喘仍然无法治愈,皮质类固醇是主要治疗方法.
- 最近的研究将糖溶性重编程与喘病因产生联系起来.
研究的目的:
- 调查皮质类固醇对控制喘的影响是否涉及调节糖解和蛋白质乳酸化.
- 探索Hif-1α-糖解轴在喘中的作用及其通过德克萨米他的调制.
主要方法:
- 在小鼠中的卵蛋白 (OVA) 挑战和用德甲 (DEX) 刺激THP-1细胞.
- 分析气道炎症,高反应性,甘油酶,热致死标志物,乳酸,甘油溶解,氧化酸化 (OXPHOS) 和蛋白质乳化.
主要成果:
- DEX减少了OVA诱导的气道炎症,高反应性和Th2细胞因子的产生.
- DEX抑制了由OVA诱导的Hif-1α-糖解轴,降低了乳酸水平.
- 喘模型中蛋白质乳化增加,但被DEX抑制,这表明与皮质类固醇疗效的联系.
结论:
- 德克萨米他的喘控制效应与抑制Hif-1α-糖解-乳酸轴和蛋白质乳糖化有关.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
Antiasthma Drugs: Methylxanthines
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...
Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Antiasthma Drugs: β2-Adrenoceptor Agonists
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce...
