Prostatitis, a clinical syndrome characterized by pelvic pain and inflammation, is common in adult males. Although several induced and spontaneous murine models of prostatitis have been explored, the role of genetic background on induction has not been well-defined.
Using a standard methodology for the induction of experimental autoimmune prostatitis (EAP), we investigated both acute and chronic inflammation on several murine genetic backgrounds.
In our colony, nonobese diabetic (NOD) mice evinced spontaneous prostatitis that was not augmented by immunization with rat prostate extract (RPE). In contrast, the standard laboratory strain Balb/c developed chronic inflammation in response to RPE immunization. Development of EAP in other strains was variable.
These data suggest that Balb/c mice injected with RPE may provide a useful model for chronic prostatic inflammation.
前列腺炎是一种以骨盆疼痛和炎症为特征的临床综合征,常见于成年男性。尽管已经探索了几种诱导和自发的前列腺炎小鼠模型,但遗传背景对诱导的作用尚未得到很好的定义。
我们使用标准的实验性自身免疫性前列腺炎(EAP)诱导方法,在几种不同的小鼠遗传背景下研究了急性和慢性炎症。
在我们的实验中,非肥胖型糖尿病(NOD)小鼠出现了自发性前列腺炎,而用大鼠前列腺提取物(RPE)免疫则不会加剧这种炎症。相比之下,标准实验室品系 Balb/c 对 RPE 免疫反应产生慢性炎症。其他品系的 EAP 发展情况则有所不同。
这些数据表明,用 RPE 注射的 Balb/c 小鼠可能为慢性前列腺炎症提供了一个有用的模型。
