Neuroinflammation At The Crossroads Of Neurodegeneration: The Roles Of Microglia And Astrocytes In Parkinson's Disease, Alzheimer's Disease, And Multiple Sclerosis, Mohannad A. Almikhlafi
Neuroinflammation At The Crossroads Of Neurodegeneration: The Roles Of Microglia And Astrocytes In Parkinson's Disease, Alzheimer's Disease, And Multiple Sclerosis, Mohannad A. Almikhlafi
Neurosciences
Neuroinflammation plays a critical role in the pathogenesis of neurodegenerative disorders such as Parkinson's disease, Alzheimer's disease, and multiple sclerosis. This review explores the underlying mechanisms of neuroinflammation, with a focus on the roles of microglia, astrocytes, peripheral immune cell infiltration, and cytokine release. The complex interplay between oxidative stress and chronic inflammation accelerates neurodegeneration, contributing to disease progression. Microglial activation, initially protective, becomes harmful when sustained over time, driving chronic inflammation. Similarly, astrocytes once considered passive are now recognized for their active involvement in both inflammatory and neuroprotective responses, depending on their activation state. Prolonged activation of microglia and …

Role Of Bevacizumab In Multiple Glioblastomas: A Retrospective Single-Center Analysis, Yongrui Zhao, Yidong Chen, Leiming Wang, Ye Cheng, Feng Yan, Jiankun Xu
Neurosciences
Objective: To explore the prognostic factors of multiple glioblastomas (M-GBMs) and the role of bevacizumab (BEV) in M-GBMs. Methods: 162 patients treated for primary glioblastoma (GBM) from 2020 to 2024 were retrospectively reviewed. Kaplan–Meier analysis was performed to compare progression-free survival (PFS) and overall survival (OS) between the single glioblastoma (S-GBM) group and the M-GBMs group. Independent predictors of OS among M-GBMs patients were evaluated via multivariable Cox regression analysis. Results: 116 patients had S-GBM, and 46 had M-GBMs. Compared with S-GBM patients, M-GBMs patients had poorer PFS (6.5 vs. 11 months, p<0.001) and OS (15.5 vs. 21 months, p=0.005). In the M-GBMs group, based on the RANO resection criteria, both univariable analysis and multivariable Cox models confirmed that the extent of resection, use of radiotherapy and chemotherapy, p53 overexpression, and use of BEV were all factors that significantly influenced OS. Specifically, the use of BEV prolonged OS from 12 months to 19.5 months (p = 0.017). From the initiation of BEV therapy, the median PFS was 5.5 months (95% CI 4.45–6.56 months), and the median survival was significantly longer than in those who did not received BEV (10 vs. 3 months, p = 0.021). Conclusion: The extent of resection, radiotherapy/chemotherapy, p53 …0.001)>

Polygenic risk score values vary with genetic ancestry due to differences in population-specific allele frequencies and linkage disequilibrium patterns. We present a framework to calibrate polygenic risk scores based on ancestral makeup. We propose the "expected polygenic risk score" or ePRS, defined as the expected value of a polygenic risk score based on one's global or local admixture patterns. We further define the "residual polygenic risk score" or rPRS as measuring the deviation of the polygenic risk score from the ePRS. The ePRS reflects the baseline ancestry-driven component of genetic risk, whereas the rPRS isolates an ancestry-agnostic measure of genetic …

A consistent postmortem finding in schizophrenia (SCZ) is reduction in dendrites' size. However, neurons with larger dendritic trees have also been encountered. In vitro experiments with neurons and neuronal-like cells coming directly from patients with SCZ showed similar results, evidencing at times more extensions and at others less arborizations. The process of extending and retracting neuronal outgrowths depends on microtubules polymerization and depolymerization. The possibility that microtubule polymerization/depolymerization is related to defects in the neuronal structure comes from several microtubular anomalies reported in SCZ such as its abnormal distribution in the cytoplasm, irregular shape of microtubules and even absence of …

Lateral Habenula And Dorsal Raphe Neurons Signal Value Computations In Multi-Attribute Decision-Making, Yang-Yang Feng
McKelvey School of Engineering Graduate Student Theses & Dissertations
Decision-making is a fundamental part of adaptive behavior and can be compromised in psychiatric illness. Humans and animals are continuously presented with objects and opportunities as options to decide between. One challenge is that these options may independently vary along multiple dimensions or attributes that we care about. This can include attributes of physical reward, such as amount, delay, or uncertainty. When these attributes are present, the possibility of an abstract, cognitive reward, advance information to resolve uncertainty, may also motivate our decisions. It is unclear how the brain makes these subjective decisions, trading off between these multiple attributes based …

Functional And Spatially Specialized Inhibition And Neuromodulation During Learning In The Hippocampus, Gerardo Enrique Molina
Functional And Spatially Specialized Inhibition And Neuromodulation During Learning In The Hippocampus, Gerardo Enrique Molina
McKelvey School of Engineering Graduate Student Theses & Dissertations
The hippocampus relies on a diverse network of regulatory components for memory formation. Neuromodulators and inhibitory interneurons act in concert with excitatory neurons to control learning. Even within one of these components there is a vast diversity of genetic or chemical composition that may come from unique sources at uniquely timed intervals or events. The goal of this dissertation is to identify specific functional-behavioral attributes of two such examples: parvalbumin (PV)-expressing interneurons and the neuromodulator dopamine, in hippocampal CA1. In separate experiments, I used two-photon microscopy of the calcium sensor, GCaMP, which measures neuronal activity, and GRAB-DA, which reports levels …

Background: Hispanic people with HIV who smoke cigarettes experience unique stressors (eg, stigma), which contribute to health disparities. Anxiety sensitivity (AS) may worsen mood management problems, which are a leading barrier to smoking cessation. Interventions targeting AS can improve HIV-specific outcomes and smoking cessation. However, no prior research has culturally tailored an AS reduction program to improve quality of life among Hispanic people with HIV who smoke. The research team previously developed a mobile health (mHealth) intervention addressing AS reduction, smoking cessation, and HIV care management for Black people with HIV who smoke. Building on this work, this study represents …

Air pollution is a growing hazard to global health. Epidemiological studies have reported a potential role of air pollutant exposure in the development or aggravation of neurodegenerative diseases. However, the underlying mechanisms are ill-defined. Ferroptosis is an iron- and reactive oxygen species (ROS)-dependent form of cell death that drives neuronal loss in neurodegenerative diseases. Our previous studies reported the involvement of adenosine 3',5'-cyclic monophosphate (cAMP) and EPAC (exchange protein directly activated by cAMP) in ferroptotic cell death. Here, we investigated the effects of diesel exhaust particles (DEP) in mouse hippocampal (HT22) neuronal cells. Our data showed that toxicity induced by …

Although learning over multiple days is more effective than a single day of training, the underlying cellular mechanisms of repeated training trials remain poorly understood. With a combination of empirical and computational approaches, we determined a critical time window for a second stimulus block of a multiday training protocol to augment long-term synaptic facilitation (LTF) of the Aplysia sensorimotor synapse and long-term enhancement of neuronal excitability (LTEE), two cellular correlates of learning and memory. A second stimulus block delivered 24 h after the first block significantly enhanced LTF and LTEE, but was without effect at 18 or 32 h. This …
