    Probing the correlation of neuronal loss, neurofibrillary tangles, and cell death markers across the Alzheimer's disease Braak stages: a quantitative study in humans
    (2018) THEOFILAS, Panos; EHRENBERG, Alexander J.; NGUY, Austin; THACKREY, Julia M.; DUNLOP, Sara; MEJIA, Maria B.; ALHO, Ana T.; LEITE, Renata Elaine Paraizo; RODRIGUEZ, Roberta Diehl; SUEMOTO, Cclaudia K.; NASCIMENTO, Camila F.; CHIN, Marcus; MEDINA-CLEGHORN, Daniel; CUERVO, Ana Maria; ARKIN, Michelle; SEELEY, William W.; MILLER, Bruce L.; NITRINI, Ricardo; PASQUALUCCI, Carlos Augusto; JACOB FILHO, Wilson; RUEB, Udo; NEUHAUS, John; HEINSEN, Helmut; GRINBERG, Lea T.
    Clarifying the mechanisms connecting neurofibrillary tangle (NFT) neurotoxicity to neuronal dysfunction in humans is likely to be pivotal for developing effective treatments for Alzheimer's disease (AD). To model the temporal progression of AD in humans, we used a collection of brains with controls and individuals from each Braak stage to quantitatively investigate the correlation between intraneuronal caspase activation or macroautophagy markers, NFT burden, and neuronal loss, in the dorsal raphe nucleus and locus coeruleus, the earliest vulnerable areas to NFT accumulation. We fit linear regressions with each count as outcomes, with Braak score and age as the predictors. In progressive Braak stages, intraneuronal active caspase-6 positivity increases both alone and overlapping with NETs. Likewise, the proportion of NFT-bearing neurons showing autophagosomes increases. Overall, caspases may be involved in upstream cascades in AD and are associated with higher NFTs. Macroautophagy changes correlate with increasing NFT burden from early AD stages.

    Neuropathology of depression in non-demented older adults: A large postmortem study of 741 individuals
    (2022) NUNES, Paula Villela; SUEMOTO, Claudia Kimie; RODRIGUEZ, Roberta Diehl; LEITE, Renata Elaine Paraizo; NASCIMENTO, Camila; PASQUALUCCI, Carlos Augusto; NITRINI, Ricardo; JACOB-FILHO, Wilson; GRINBERG, Lea T.; LAFER, Beny
    Associations between age-related neuropathological lesions and adult-onset lifetime major depressive disorder (a-MDD), late-life MDD (LLD), or depressive symptoms close to death (DS) were examined in a large community sample of non-demented older adults. Seven hundred forty-one individuals (age at death = 72.2 +/- 11.7 years) from the Biobank for Aging Studies were analyzed. a-MDD was present in 54 (7.3%) participants, LLD in 80 (10.8%), and DS in 168 (22.7%). After adjustment for covariates and compared to controls, a-MDD, LDD and DS were associated with small vessel disease ( p = 0.039, p = 0.003, and p = 0.003 respectively); LLD, and DS were associated with brain infarcts ( p = 0.012, p = 0.018, respectively) and Lewy body disease ( p = 0.043, p = 0.002, respectively). DS was associated with betaamyloid plaque burden ( p = 0.027) and cerebral amyloid angiopathy ( p = 0.035) in cognitively normal individuals (Clinical Dementia Rating scale = 0). Vascular brain pathology was the strongest correlate of clinical depictions of depression in the absence of dementia, corroborating the vascular hypothesis of depression. Lewy body pathology underlay DS. An older adult with DS or LLD should be monitored for possible cognitive decline or neurodegenerative disorders.(c) 2022 Elsevier Inc. All rights reserved.
