TREX1 distribution in human brain was further evaluated by immunohistochemical analyses of formalin-fixed, paraffin-embedded samples from normal controls and patients with RVCL and ischemic stroke. Dual staining was performed to determine cell types expressing TREX1 in human brain tissue. METHODS: We produced a rabbit polyclonal antibody (pAb) to TREX1 to characterize TREX1 by Western blotting (WB) of cell lysates from normal controls and subjects carrying an RVCL frame-shift mutation. However, the endogenous expression of TREX1 in human brain has not been studied. , Hereditary Central Nervous System Demyelinating Diseases/diagnostic imagingД«ACKGROUND: Mutations in the three-prime repair exonuclease 1 (TREX1) gene have been associated with neurological diseases, including Retinal Vasculopathy with Cerebral Leukoencephalopathy (RVCL). , Cognitive Dysfunction/diagnostic imaging , Hereditary Central Nervous System Demyelinating Diseases/pathology Progressive elevation of white matter OEF suggests that microvascular ischemia may underlie neurodegeneration in RVCL-S.

White matter volumes in RVCL-S declined linearly, providing a potential metric against which to test the efficacy of future therapies.

CONCLUSION: RVCL-S is a monogenic microvasculopathy affecting predominantly the white matter with regard to atrophy and cognitive impairment. Lesion volumes, regardless of subtype, progressed/regressed with high variability as a function of age, while FLAIR lesion burden increased near time to death (p < 0.001). Multiple cognitive domains, specifically those measuring working memory and processing speed, were impaired in RVCL-S. Normalized OEF was elevated in RVCL-S and increased with disease duration. White matter atrophy in RVCL-S was highly linear (ПЃ = -0.908, p < 0.0001).

White matter volume and microstructure declined faster in those with RVCL-S compared to controls. RESULTS: Twenty individuals with RVCL-S and 26 controls were enrolled. The RVCL-S cohort was included in a longitudinal analysis of lesion subtypes in which hyperintense lesions on fluid-attenuated inversion recovery (FLAIR), T1-postgadolinium, and diffusion-weighted imaging were delineated and quantified volumetrically. Asymmetric spin echo acquisition permitted voxel-wise oxygen extraction fraction (OEF) calculation as an in vivo marker of microvascular ischemia. Gray and white matter volume and disruption of white matter microstructure were quantified. METHODS: We prospectively performed MRI and cognitive testing in RVCL-S and healthy control cohorts. OBJECTIVE: To characterize lesion evolution and neurodegeneration in retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations (RVCL-S) using multimodal MRI.
