Although the prevalence of keratitis (AK) is rare, its incidence in contact lens wearers has increased. infections can lead to the loss of vision if the diagnosis and treatment are delayed. In this study, we investigated the diagnostic potential of two antibodies raised against the adenylyl cyclase-associated protein (ACAP) and periplasmic binding protein (PBP) of in the AK mouse model. The specificity of ACAP and PBP antibodies to was confirmed by immunocytochemistry. AK mouse models were produced by corneal infections with trophozoites for 7 days and 21 days. Enzyme-linked immunosorbent assay results revealed that both ACAP and PBP antibodies successfully detected antigens in the tears and eyeball lysates of the AK mouse model. The detection levels of antigens were similar at both infection time points. Anti- IgG, IgA, and IgM antibodies were evaluated from the sera of the AK mouse model. Notably, IgM and IgA antibody responses were highest and lowest at both time points, respectively. Our findings revealed that both ACAP and PBP antibodies could detect antigens in the tears and eyeball lysates of the AK mouse model. These results provide important information for understanding infections and developing a new diagnostic tool for AK.
尽管角膜炎(AK)的患病率很低,但其在隐形眼镜佩戴者中的发病率有所上升。如果诊断和治疗延迟,感染可能导致视力丧失。在本研究中,我们调查了两种针对[具体病原体名称未给出]的腺苷酸环化酶相关蛋白(ACAP)和周质结合蛋白(PBP)产生的抗体在AK小鼠模型中的诊断潜力。通过免疫细胞化学证实了ACAP和PBP抗体对[具体病原体名称未给出]的特异性。通过用[具体病原体名称未给出]滋养体角膜感染7天和21天建立AK小鼠模型。酶联免疫吸附测定结果显示,ACAP和PBP抗体均成功检测到AK小鼠模型泪液和眼球裂解物中的[具体病原体名称未给出]抗原。在两个感染时间点,[具体病原体名称未给出]抗原的检测水平相似。从AK小鼠模型的血清中评估抗[具体病原体名称未给出]IgG、IgA和IgM抗体。值得注意的是,在两个时间点,IgM和IgA抗体反应分别最高和最低。我们的研究结果表明,ACAP和PBP抗体均可检测到AK小鼠模型泪液和眼球裂解物中的[具体病原体名称未给出]抗原。这些结果为理解[具体病原体名称未给出]感染和开发AK的新诊断工具提供了重要信息。
