Description

Adult-onset leukoencephalopathy with axonal spheroids (ALAS) is a group of hereditary, progressive, neurodegenerative disorders involving primarily the central nervous system white matter (WM). ALAS is characterized by patchy, asymmetrical myelin loss and axonal destruction in the WM, predominantly involving the frontoparietal regions. However, the asymmetrical and heterogenous involvement of different brain regions remains poorly characterized.

In this study, digital spatial profiling was performed to investigate the region-specific expressions of 60 proteins. Conventional immunohistochemistry methods was used validate intrepretation of probes. Using a high-plex and high-throughput method, we provide evidence of regional heterogeneity in ALAS, particularly involving key markers of microglia composition, glial cell subtype and autophagy.

Characterizing the Heterogeneity of Adult-Onset Leukoencephalopathy with Axonal Spheroids: A Digital Spatial Profiling Study

Adult-onset leukoencephalopathy with axonal spheroids (ALAS) is a group of hereditary, progressive, neurodegenerative disorders involving primarily the central nervous system white matter (WM).
