Scientific Rationale for the Treatment of Cognitive Deficits from Long COVID

Neurology International, Journal Year: 2023, Volume and Issue: 15(2), P. 725 - 742

Published: May 31, 2023

Sustained cognitive deficits are a common and debilitating feature of “long COVID”, but currently there no FDA-approved treatments. The functions the dorsolateral prefrontal cortex (dlPFC) most consistently afflicted by long COVID, including in working memory, motivation, executive functioning. COVID-19 infection greatly increases kynurenic acid (KYNA) glutamate carboxypeptidase II (GCPII) brain, both which can be particularly deleterious to PFC function. KYNA blocks NMDA nicotinic-alpha-7 receptors, two receptors required for dlPFC neurotransmission, GCPII reduces mGluR3 regulation cAMP-calcium-potassium channel signaling, weakens network connectivity neuronal firing. Two agents approved other indications may helpful restoring physiology: antioxidant N-acetyl cysteine inhibits production KYNA, α2A-adrenoceptor agonist guanfacine regulates signaling is also anti-inflammatory. Thus, these treating symptoms COVID.

Study of tree shrew biology and models: A booming and prosperous field for biomedical research

动物学研究, Journal Year: 2024, Volume and Issue: 45(4), P. 877 - 909

Published: Jan. 1, 2024

The tree shrew (Tupaia belangeri) has long been proposed as a suitable alternative to non-human primates (NHPs) in biomedical and laboratory research due its close evolutionary relationship with primates. In recent years, significant advances have facilitated studies, including the determination of genome, genetic manipulation using spermatogonial stem cells, viral vector-mediated gene delivery, mapping brain atlas. However, limited availability shrews globally remains substantial challenge field. Additionally, determining key questions best answered constitutes another difficulty. Tree models historically used study hepatitis B virus (HBV) C (HCV) infection, myopia, psychosocial stress-induced depression, more studies focusing on developing animal for infectious neurodegenerative diseases. Despite these efforts, impact not yet matched that rodent or NHP research. This review summarizes prominent advancements reflects biological addressed this model. We emphasize intensive dedication robust international collaboration are essential achieving breakthroughs studies. use unique resource is expected gain considerable attention application advanced techniques development viable models, meeting increasing demands life science

Animal Models of Non-Respiratory, Post-Acute Sequelae of COVID-19

Viruses, Journal Year: 2025, Volume and Issue: 17(1), P. 98 - 98

Published: Jan. 14, 2025

Post-acute sequelae of COVID-19 (PASC) are a diverse set symptoms and syndromes driven by dysfunction multiple organ systems that can persist for years negatively impact the quality life millions individuals. We currently lack specific therapeutics patients with PASC, due in part to an incomplete understanding its pathogenesis, especially non-pulmonary sequelae. Here, we discuss three animal models have been utilized investigate PASC: non-human primates (NHPs), hamsters, mice. focus on neurological, gastrointestinal, cardiovascular PASC highlight advances mechanistic insight made using these models, as well discussing warrant continued intensive research.

Cell atlas of CCl₄-induced progressive liver fibrosis reveals stage-specific responses

动物学研究, Journal Year: 2023, Volume and Issue: 44(3), P. 451 - 466

Published: Jan. 1, 2023

Chronic liver injury leads to progressive fibrosis and ultimately cirrhosis, a major cause of morbidity mortality worldwide. However, there are currently no effective anti-fibrotic therapies available, especially for late-stage patients, which is partly attributed the knowledge gap regarding cell heterogeneity cell-specific responses in different stages. To reveal multicellular networks regulating mammalian from mild severe phenotypes, we generated single-nucleus transcriptomic atlas encompassing 49 919 nuclei corresponding all main types at stages murine carbon tetrachloride (CCl

Comparative transcriptome analysis between rhesus macaques (<i>Macaca mulatta</i>) and crab-eating macaques (<i>M. fascicularis</i>)

动物学研究, Journal Year: 2023, Volume and Issue: 45(2), P. 299 - 310

Published: Dec. 28, 2023

Understanding the variations in gene expression between species is pivotal for deciphering evolutionary diversity phenotypes. Rhesus macaques and crab-eating serve as crucial nonhuman primate biomedical models with different phenotypes, but large-scale of comparative transcriptome research these two has yet to be fully elucidated. Here, we conduct systematic comparisons utilizing newly sequenced RNA-seq data from 84 samples (41 Mfa 43 Mmu samples) encompassing 14 common tissues. Our findings reveal that a small fraction genes (~3.7%) show differential macaque species, while ~36.5% tissue-specific both macaques. We also compare humans ~22.6 % orthologous at least 2 Moreover, ~19.41% overlapped macaque-specific structural variants are more likely Of these, FAM220A shows elevated compared because lineage-specific duplication. In summary, our study presents analysis transcriptomes within humans. These insights into will enhance utility contributing broader realm genomic studies.

Long COVID: From olfactory dysfunctions to viral Parkinsonism

World Journal of Otorhinolaryngology - Head and Neck Surgery, Journal Year: 2024, Volume and Issue: 10(2), P. 137 - 147

Abstract Neurological and psychiatric complications continue to be a public health concern in long coronavirus disease 2019 (COVID‐19). This varies from olfactory dysfunctions such as parosmia cognitive emotional challenges. Historically, the surge of neurological disorders followed viral pandemics, for example, emergence Encephalitis Lethargica after outbreak Spanish Influenza. During COVID‐19 infection, problems associated with sense smell reports affected limbic brain areas are leading growing about similarity symptoms pattern degeneration observed at onset Parkinson's Alzheimer's disease. These reveal essentiality long‐term studies functions post‐COVID era experiments using animal models dissect neural basis these complications. In this manuscript, we summarize research reporting potential correlation between pandemic outbreaks historical perspective. Further, discuss providing evidence neurodegeneration due severe acute respiratory syndrome 2 infection by focusing on Parkinsonism.
