Article Synopsis
  • Reactivation of the Epstein-Barr virus (EBV) has been linked to various diseases, particularly neurological conditions like Alzheimer's and multiple sclerosis, according to a recent study.
  • The study demonstrated that exposure to EBV and its glycoprotein M (gM) led to cognitive decline and increased anxiety in mice, alongside significant changes in brain structure and inflammation markers.
  • Elevated levels of key proteins related to neuroinflammation and Alzheimer's risk were found, indicating a strong association between EBV/gM and neurological issues.

Neurotropic viruses can infiltrate the CNS by crossing the blood-brain barrier (BBB) through various mechanisms including paracellular, transcellular, and "Trojan horse" mechanisms during leukocyte diapedesis. These viruses belong to several families, including retroviruses; human immunodeficiency virus type 1 (HIV-1), flaviviruses; Japanese encephalitis (JEV); and herpesviruses; herpes simplex virus type 1 (HSV-1), Epstein-Barr virus (EBV), and mouse adenovirus 1 (MAV-1). For entering the brain, viral proteins act upon the tight junctions (TJs) between the brain microvascular endothelial cells (BMECs).

Article Synopsis
  • * Researchers used an inhibitor, methyl-β-cyclodextrin (MβCD), to deplete membrane cholesterol in cells and found significant changes in the expression of EBV latent genes and key signaling molecules related to infection.
  • * Results indicated that lower cholesterol levels led to decreased expression of certain proteins linked to EBV infection and revealed alterations in triglycerides and fatty acid levels, suggesting cholesterol's critical role in the pathogenesis of EBV in brain cells related to neurological disorders.

Epigallocatechin-3-gallate (EGCG), a polyphenolic moiety found in green tea extracts, exhibits pleiotropic bioactivities to combat many diseases including neurological ailments. These neurological diseases include Alzheimer's disease, multiple sclerosis, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis. For instance, in the case of Alzheimer's disease, the formation of a β-sheet in the region of the 10th-21st amino acids was significantly reduced in EGCG-induced oligomeric samples of Aβ40.

Epstein-Barr virus (EBV) is known to be associated with several cancers along with neurological modalities like Alzheimer's disease (AD) and multiple sclerosis (MS). Previous study from our group revealed that a 12 amino acid peptide fragment (SYKHVFLSAFVY) of EBV glycoprotein M (gM) exhibits amyloid-like self-aggregative properties. In the current study, we have investigated its effect on Aβ aggregation along with its effect on neural cell immunology and disease markers.

Viruses utilize clever strategies of interacting with various cellular factors, to remodel an organelle function, for the establishment of successful infection. In recent decades, numerous studies revealed the exploitation of the peroxisomal compartment by viruses. Epstein-Barr virus (EBV) is a ubiquitous virus linked with various cancers and neurological disorders.

Bacteria emit a large number of volatile organic compounds (VOCs) into the environment. VOCs are species-specific and their emission depends on environmental conditions, such as growth medium, pH, temperature, incubation time and interaction with other microorganisms. These VOCs can enhance plant growth, suppress pathogens and act as signaling molecules during plant-microorganism interactions.

Herpesviruses are ubiquitous viruses, specifically the Epstein Barr virus (EBV). EBV and Kaposi's sarcoma-associated herpesvirus (KSHV) establish their latency for a long period in B-cells and their reactivation instigates dreadful diseases from cancer to neurological modalities. The envelope glycoprotein of these viruses makes an attachment with several host receptors.

Epstein-Barr virus (EBV), a known tumorigenic virus, is associated with various neuropathies, including multiple sclerosis (MS). However, there is no anti-EBV FDA-approved drug available in the market. Our study targeted EBV protein EBV nuclear antigen 1 (EBNA1), crucial in virus replication and expressed in all the stages of viral latencies.

Article Synopsis
  • Coronaviruses are large RNA viruses with various strains that infect animals and are known for outbreaks like SARS, MERS, and COVID-19, caused by SARS-CoV-2 first identified in Wuhan, China, and declared a pandemic by WHO on March 11, 2020.
  • The review covers the virus's origin, transmission, mutations, and their effects on host physiology, emphasizing the need to study mutations to better understand virulence and develop effective treatments.
  • It highlights the role of comorbidities like hypertension and diabetes in COVID-19 outcomes and discusses current diagnostic methods, as well as the challenges clinicians face due to the lack of available medications.
