Single-Cell Transciptomic Analysis Reveals Age-Related Remodeling Of Brain Endothelial Cells, Hai Duc Nguyen, Summer Siddiqui, Diana G. Bohannon, Robert V. Blair, Hong-Wen Deng, Alexandre Prat, Woong-Ki Kim

Microbiology & Molecular Cell Biology Faculty Publications

Blood–brain barrier (BBB) integrity naturally declines with age. Brain endothelial cells (ECs) and pericytes (PCs) form the BBB, and aging impairs tight junctions, likely via altered PC-to-EC signaling. However, the molecular mechanisms underlying this impairment remain unclear. Using single-cell RNA sequencing, we profiled 68,316 brain ECs expressing 15,564 genes from young and old mice. Unsupervised clustering and annotation revealed five distinct EC subtypes—Capillary EC1, Capillary EC2, Arterial EC, Venous EC1, and Venous EC2—defined by marker genes Mfsd2a, Plvap, Bmx, Nr2f2, and Vcam1, respectively. Aging shifted EC subtype distribution, with reduced Capillary EC1 (45% vs. 57%) and increased Arterial …

Engineering Plga Nanoparticle Size To Modulate Immune Responses After Spinal Cord Injury, Daniel J. Kolpek

University of Kentucky Doctoral Dissertations

Spinal cord injury is a severe and debilitating condition that often results in lifelong complications, including paralysis. Many of these chronic outcomes are driven by a sustained inflammatory response at the injury site, which limits tissue regeneration and functional recovery. As a result, therapeutic strategies that modulate this immune response have gained significant interest. Polymer based nanoparticle therapies have emerged as a promising approach due to their ability to interact with and influence immune cell behavior. Importantly, the physicochemical properties of nanoparticles can be precisely tuned to optimize these effects. Among these properties, size has been shown to influence key …

Background

Post-acute sequelae of SARS-CoV-2 infection, more commonly known as long COVID, has emerged as a major health problem. The pathogenesis of long COVID is unknown, but among the leading hypotheses is viral persistence. We aimed to investigate whether the use of the SARS-CoV-2 antiviral nirmatrelvir-ritonavir improved long COVID symptoms.

Methods

We conducted a double-blind, placebo-controlled, randomised trial involving adults who had developed persistent symptoms (≥12 weeks) associated with three major symptom phenotypes (cognitive, autonomic, or exercise) after acute SARS-CoV-2 infection at 69 US sites. Participants were eligible if they were 18 years or older and had a previous suspected, …

A Comprehensive Overview Of Neurophysiological Correlates Of Cognitive Impairment In Amyotrophic Lateral Sclerosis, Seyyed Bahram Borgheai, Brie E. Achorn, Alyssa H. Zisk, Sarah M. Hosni, Karl E. G. Richter, Frank S. Menniti, Yalda Shahriari

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that leads to the gradual loss of motor control, typically resulting in paralysis and death within 3 to 5 years of diagnosis. ALS shares neuropathological and genetic associations with fronto-temporal dementia (FTD), a neurodegenerative condition primarily impacting cognitive functions. These two conditions are increasingly viewed as manifestations of a single molecular disease process that affects distinct brain systems, impacting motor neuronal pathways in ALS and fronto-cortical functions in FTD. However, this simple dichotomy belies the complexity of these conditions. In particular, patients with primary motor ALS can also experience significant cognitive …

The Effects Of Vitamin K On Neuronal Ferroptosis, Chelsey P. Eighmey

Electronic Theses & Dissertations (2024 - present)

Dementia is a crippling illness affecting millions worldwide causing significant public health burdens with long-term care. The lack of treatment options results in many years of suffering for affected individuals and their loved ones who often become primary caretakers. Decades of study have focused on treating dementia with little-to-no success, so an emphasis is needed on attempting to prevent disease progression altogether. This research explored vitamin K as a potential strategy for prevention of dementia onset or progression through the mechanism of suppressing ferroptosis. Ferroptosis is a type of cell death suggested to contribute to the hallmark traits of Alzheimer’s …

Isg15 Dysregulates Endoplasmic Reticulum-Mitochondrial Contacts And Calcium Homeostasis In Ataxia Telangiectasia, Oygul Mirzalieva, Ryan E. Reed, Arthur L. Haas, Meredith A. Juncker, Patrick Logarbo, Jennifer M. Klein, David Worthylake, Shyamal D. Desai

School of Graduate Studies Faculty Publications

Dysregulation of endoplasmic reticulum and mitochondrial (ER:Mit) contacts and mitochondrial calcium (mitCa2+) homeostasis are found in several neurodegenerative disorders, including Ataxia Telangiectasia (A-T). However, the cellular basis of these defects remains unclear. Previously, we demonstrated that the aberrantly elevated Interferon-Stimulated Gene 15 (ISG15) pathway inhibits protein polyubiquitylation, its dependent protein turnover, and mitophagy pathways in A-T. Literature indicates that silencing of mitochondrial ubiquitin ligase 1 (MUL1) stabilizes mitofusin2 (MFN2) and attenuates mitCa2+ uptake from ER to Mit (mitCa2+influx) in primary neurons. We have replicated these findings in apparently healthy fibroblasts. We hypothesized that elevated ISG15 may inhibit ubiquitin-dependent MUL1-mediated degradation …

Evaluating The Effect Of Ethnicity And Amyloid On Gait Speed In The Healthy Aging Brain Study-Health Disparities Study, Alexandra M. Reed, Andrew Hooyman, Edward Ofori, Sydney Y. Schaefer

Physical Therapy Faculty Articles and Research

Background

Many novel Alzheimer's disease (AD) biomarkers have been studied in non-Hispanic White populations, despite Hispanic/Latino adults being 1.5 times more likely to develop AD and receiving a later diagnosis. Equitable, accessible assessments are needed to identify individuals at risk earlier. While cognitive screening monitors early AD signs, neuropsychological tests are often inequitable across ethnicity, race, and other social determinants of health. However, we have shown that performance-based motor assessments may be less susceptible to demographic factors than memory tests, and may be more equitable for screening older adults. Gait speed has been linked to elevated amyloid in non-Hispanic White …

Hepatocyte-Specific Lrp1 Silencing Exacerbates Brain Amyloidosis Without Compensatory Ldl Receptor Family Involvement, Brian Carson, Josephine Chu, Devaraj V. Chandrashekar, Jerome Garcia, Rachita K. Sumbria, Derick Han

Pharmacy Faculty Articles and Research

Background

LDL receptor related protein 1 (LRP1) is a major hepatic receptor involved in lipoprotein metabolism, protease degradation, transmembrane receptor modulation, and clearance of excess protein, such as Aβ. Decreased expression of LRP1 due to liver injury can impair receptor-mediated clearance, increasing Aβ availability in the periphery. We investigated the effects of hepato-specific silencing of LRP1 on Aβ deposition in the brain. Additionally, other LDL family members (LRP5, LRP6, and LDLR) that may participate in Aβ clearance were monitored in the liver to ensure non-compensatory effects of LRP1 silencing.

Method

4-month-old male double transgenic (APP/PS1) AD mice were injected with …
