HIV and Alzheimer’s disease are associated with cognitive changes characterized by neuroinflammation or neurodegeneration, respectively. Dr. Galasko describes how Olink® PEA technology was employed to profile proteins related to mild cognitive impairment in HIV and Alzheimer’s patients compared to controls using cerebrospinal fluid (CSF). Dr. Galasko demonstrates that Olink® Target platforms allow the sensitive analysis of proteins in CSF, which has a lower total protein content than other sample types (e.g., plasma). For example, between 42 – 77% of targeted proteins by Olink® Target 96 panels (Inflammation, Neuro-exploratory, Neurology) were detected in CSF within the lower limit of quantitation. Of the 17 detectable proteins that are shared between Olink® Target 48 and 96 panels, the Pearson’s r correlation ranged from 0.586 – 0.972. Preliminary data analysis revealed differentially expressed proteins between Alzheimer’s and HIV patients compared to healthy controls, which may shed further light on the underlying biology of these diseases.
