Circulating levels of matrix metalloproteinases (MMP-1 and 7) have been found to correlate with the severity of brain injury in HIV-infected subjects. This study used high-resolution neuroanatomic imaging and automated segmentation algorithms to clarify this relationship. Both metalloproteinases were significantly correlated with increased cerebrospinal fluid volume fraction. Comprehensive brain volumetric analysis revealed a more marked relationship with atrophy for MMP-7, which was significantly correlated with neural injury in multiple brain regions and nearly all ventricular measurements. MMP-7 was also correlated with measures of virologic and cognitive status.
研究发现,循环基质金属蛋白酶(MMP-1 和 MMP-7)水平与感染 HIV 的患者的脑损伤严重程度相关。本研究使用高分辨率神经解剖成像和自动分割算法来阐明这种关系。两种金属蛋白酶均与脑脊液体积分数增加显著相关。全面的脑容量分析显示,MMP-7 与萎缩的关系更为显著,它与多个脑区的神经损伤以及几乎所有脑室测量值均显著相关。MMP-7 还与病毒学和认知状态的测量值相关。
