甲基苯丙胺(METH)是一种强效且高度成瘾的中枢神经系统(CNS)兴奋剂。此外,甲基苯丙胺会对免疫反应产生不利影响,这可能导致吸毒者某些感染的发生率更高,进展更快。然而,没有研究显示METH对特定器官内的炎症、细胞参与和细胞因子产生的影响。使用METH给药的小鼠模型,我们证明METH不同程度地改变了小鼠肺、肝、脾和肾中的白细胞募集并改变了细胞介质。我们的研究结果证明了METH对不同组织内免疫应答的多效性作用。这些改变对组织内稳态和宿主对包括入侵病原体在内的各种损伤的反应能力具有深远的影响。
Methamphetamine (METH) is a potent and highly addictive central nervous system (CNS) stimulant. Additionally, METH adversely impacts immunological responses, which might contribute to the higher rate and more rapid progression of certain infections in drug abusers. However no studies have shown the impact of METH on inflammation within specific organs, cellular participation and cytokine production. Using a murine model of METH administration, we demonstrated that METH modifies, with variable degrees, leukocyte recruitment and alters cellular mediators in the lungs, liver, spleen and kidneys of mice. Our findings demonstrate the pleotropic effects of METH on the immune response within diverse tissues. These alterations have profound implications on tissue homeostasis and the capacity of the host to respond to diverse insults, including invading pathogens.
