Recent studies indicate the involvement of inflammatory mechanisms in amyloid-β (Aβ) and tau deposition in the brain. Due to the complexity of the immune responses and the intricate interplay between the peripheral and the central nervous systems, identifying biomarkers that reflect the brain inflammatory changes in AD has been challenging. With this study, we sought to characterize immune-related proteins in cerebrospinal fluid (CSF) and plasma, in relation toAβ and tau PET.  \nMethods: Participants from the Translational Biomarker for Aging and Dementia Cohort (TRIAD) incorporating within the AD spectrum, and with available Aβ PET ([18 F]AZD4694) and tau PET ([18 F]MK6240), had plasma (n = 376) and CSF (n = 277) samples analyzed with the NULISA technology (Alamar Biosciences®). A total of 309 inflammation-related proteins were selected and included in our analysis. Validation cohorts were used to generalize the results: ADNI had CSF samples (n = 384) analyzed with the SomaScan technology (SomaLogic® ); and BBDP had plasma samples (n = 253) analyzed with NULISA technology (Alamar Biosciences® ). Standardized (Std)β coefficients from linear models relating Aβ - and tau-PET SUVR (both included as independent variables) to the CSF and plasma protein levels. Models included age and sex and as covariates.  \nResults: Several proteins exhibit distinct patterns in relation toAβ and tau pathologies. Notably, specific proteins show strong positive associations with global Aβ-PET levels,  \nThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.  \n© 2025 The Alzheimer’s Association.
