It has been presumed that gamma interferon (IFN-gamma), which plays an essential role in antilisterial resistance, is produced late in Listeria monocytogenes infection. In the present study, however, IFN-gamma was detected in the bloodstreams and spleens of mice from days 1 to 4 of L. monocytogenes infection by both a double-sandwich enzyme-linked immunosorbent assay and an immunohistochemical technique, suggesting that endogenous IFN-gamma is produced early but not late in L. monocytogenes infection.
据推测,在抗李斯特菌感染中起关键作用的γ干扰素(IFN-γ)是在单核细胞增生李斯特菌感染后期产生的。然而,在本研究中,通过双夹心酶联免疫吸附测定法和免疫组织化学技术,在单核细胞增生李斯特菌感染第1至4天的小鼠血液和脾脏中检测到了IFN-γ,这表明内源性IFN-γ是在单核细胞增生李斯特菌感染早期而非后期产生的。
