淋巴细胞性脉络丛脑膜炎病毒感染小鼠中枢神经系统(CNS)引起致命的免疫病理,通过血脑屏障破坏和惊厥发作。虽然淋巴细胞-脉络丛脑膜炎病毒特异性细胞毒性T淋巴细胞(ctl)对疾病至关重要,但其作用机制尚不清楚。为了深入了解疾病的发病机制,我们用双光子显微镜观察了脑膜中免疫细胞的动态。在这里,我们报告了动态ctl的可视化和大量继发性募集的致病性单核细胞和中性粒细胞,这是血管渗漏和急性致死所必需的。ctl表达多种能够募集骨髓单核细胞的化学引诱剂。我们得出结论,CD8+ t细胞依赖性疾病可以在缺乏直接t细胞效应机制的情况下进行,而依赖于ctl募集的骨髓单核细胞。
Lymphocytic choriomeningitis virus infection of the mouse central nervous system (CNS) elicits fatal immunopathology through blood–brain barrier breakdown and convulsive seizures. Although lymphocytic-choriomeningitis-virus-specific cytotoxic T lymphocytes (CTLs) are essential for disease, their mechanism of action is not known. To gain insights into disease pathogenesis, we observed the dynamics of immune cells in the meninges by two-photon microscopy. Here we report visualization of motile CTLs and massive secondary recruitment of pathogenic monocytes and neutrophils that were required for vascular leakage and acute lethality. CTLs expressed multiple chemoattractants capable of recruiting myelomonocytic cells. We conclude that a CD8+T-cell-dependent disorder can proceed in the absence of direct T-cell effector mechanisms and rely instead on CTL-recruited myelomonocytic cells.
