Cerebral microvascular density, blood-brain barrier permeability, and support for neuroinflammation indicate early aging in a Marfan syndrome mouse model by Tala Curry-Koski, Tala Curry-Koski, Liam P. Curtin, Mitra Esfandiarei, Mitra Esfandiarei, Mitra Esfandiarei, Theresa Currier Thomas, Theresa Currier Thomas, Theresa Currier Thomas, Theresa Currier Thomas

“…Despite these significant clinical observations, investigation into cerebrovascular dysfunction and neuropathology in MFS remains limited.MethodsUsing 6M-control (C57BL/6) and 6M-MFS (Fbn1C1041G/+) and healthy 12M-control male and female mice, we test the hypothesis that abnormal Fbn1 protein expression is associated with altered cerebral microvascular density, BBB permeability, and neuroinflammation in the PCA-perfused hippocampus, all indicative of a pre-mature aging brain phenotype. Glut1 immunostaining was used to quantify microvascular density, IgG staining to assess BBB permeability, and microglial counts to evaluate neuroinflammation.ResultsUsing Glut1 staining, 6M-MFS mice and 12M-CTRL similarly present decreased microvascular density in the dentate gyrus (DG), cornu ammonis 1 (CA1), and cornu ammonis 3 (CA3) regions of the hippocampus. 6M-MFS mice exhibit increased BBB permeability in the DG and CA3 as evident by Immunoglobulin G (IgG) staining. …”

Neurobiology of Vascular Dementia by Ana-Maria Enciu, Stefan N. Constantinescu, Laurenţiu M. Popescu, Dafin F. Mureşanu, Bogdan O. Popescu

“…However, in a very large majority of cases, these alterations occur in an already aged brain, characterized by a milieu of cellular and molecular events common for different neurodegenerative diseases. …”

Neuroinflammation and Cerebrovascular Disease in Old Age: A Translational Medicine Perspective by Mario Di Napoli, Imtiaz M. Shah

“…Ischemic changes in the commonly used young animal stroke models do not reflect the molecular changes associated with the aged brain. Neuroinflammation and oxidative stress are important pathogenic processes occurring during the acute phase of cerebral ischemia. …”

Comparing the effect of Centella asiatica L. and Acalypha indica L. treatment to carbonyl and glutathione level in the brains of old rats by Ninik Mudjihartini, Reni Paramita, Astrid Mariam Khairani Siregar, Estiana Filzadiyanti, Pungguri Ayu Nega Sarsanti, Erni Purwaningsih

“…Furthermore, treating AI did not reduce the brain carbonyl and GSH levels in aged brain rats. Conclusion: Centella asiatica can reduce the protein destruction that occurs with increasing age. …”

Adult Hippocampal Neurogenesis in Alzheimer’s Disease: An Overview of Human and Animal Studies with Implications for Therapeutic Perspectives Aimed at Memory Recovery by Stefano Farioli-Vecchioli, Valentina Ricci, Silvia Middei

“…Newborn neurons integrate into existing neuronal networks, where they play a key role in hippocampal functions, including learning and memory. In the ageing brain, neurogenic capability progressively declines while in parallel increases the risk for developing Alzheimer’s disease (AD), the main neurodegenerative disorder associated with memory loss. …”

Chondroitin 6-Sulfation Regulates Perineuronal Net Formation by Controlling the Stability of Aggrecan by Shinji Miyata, Hiroshi Kitagawa

“…Here we found that overexpression of chondroitin 6-sulfotransferase-1 (C6ST-1), which catalyzes 6-sulfation of CS chains, selectively decreased aggrecan, a major CSPG in PNNs, in the aged brain without affecting other PNN components. Both diffuse and PNN-associated aggrecans were reduced by overexpression of C6ST-1. …”

Exosome-based targeted delivery of NF-κB ameliorates age-related neuroinflammation in the aged mouse brain by Chae-Jeong Lee, Seung Hyun Jang, Jiwoo Lim, Hyunju Park, So-Hee Ahn, Seon Young Park, Hyangmi Seo, Soo-Jin Song, Jung-A Shin, Chulhee Choi, Heon Yung Gee, Youn-Hee Choi

“…Treatment with Exo-srIκB also suppressed the interactions between macrophages/microglia and T and B cells in the aged brain. We demonstrated that Exo-srIκB successfully alleviates neuroinflammation by primarily targeting activated macrophages and partially modulating the functions of age-related interferon-responsive microglia in the brain. …”

The REpeated ASSEssment of SurvivorS in intracerebral haemorrhage: protocol for a multicentre, prospective observational study by Daniel Woo, Richard Thompson, Carl D Langefeld, Nichol McBee, Daniel Hanley, Matthew L Flaherty, Lauren Sansing, Karen Lane, Lee A Gilkerson, Achala Vagal, Nathan Walborn, Wendy Ziai, Noeleen Ostapkovich, Kevin Triene, Timothy David Howard

“…Background The REpeated ASSEssment of SurvivorS (REASSESS) study will conduct long-term cognitive, functional and neuropsychiatric performance assessments to determine whether evacuation of spontaneous intracerebral haemorrhage (ICH) reduces the risk of later cognitive decline in the ageing brain.Methods and analysis This study will compare rates of cognitive decline under two treatment strategies for ICH. …”

Stroke Induces a BDNF-Dependent Improvement in Cognitive Flexibility in Aged Mice by Josh Houlton, Lisa Y. Y. Zhou, Deanna Barwick, Emma K. Gowing, Andrew N. Clarkson

“…Recently, we have established an animal model of stroke that results in delayed impairment in spatial memory, allowing us to better investigate cognitive deficits. Young and aged brains show different recovery profiles after stroke; therefore, we assessed aged-related differences in poststroke cognition. …”

Age-associated microglial transcriptome leads to diminished immunogenicity and dysregulation of MCT4 and P2RY12/P2RY13 related functions by Martin Škandík, Lara Friess, Guillermo Vázquez-Cabrera, Lily Keane, Kathleen Grabert, Mireia Cruz De los Santos, Mercedes Posada-Pérez, Austeja Baleviciute, Mathilde Cheray, Bertrand Joseph

“…Through the integration of in vitro cultured BV-2 microglia with primary microglia datasets, we identify critical molecular determinants of microglial cellular aging confirmed in human-aged brain tissue. This comprehensive approach offers potential insights for understanding and potentially reprogramming aged microglia, with implications for combating age-related neurological disorders.…”
