Endothelial thrombomodulin downregulation caused by hypoxia contributes to severe infiltration and coagulopathy in COVID-19 patient lungs


Authors: Taejoon Won, Megan K. Wood, David M. Hughes, Monica V. Talor, Zexu Ma Jowaly Schneider, et al. Published:January 12, 2022DOI:https://doi.org/10.1016/j.ebiom.2022.103812 Background Thromboembolism is a life-threatening manifestation of coronavirus disease 2019 (COVID-19). We investigated a dysfunctional phenotype of vascular endothelial cells in the lungs during COVID-19. Methods We obtained the lung specimens from the patients […]

What Role does Endothelial Infection Play in SARS-CoV-2 Infection?


Authors: By Dr. Liji Thomas, MD Reviewed by Emily Henderson, B.Sc. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause inflammatory lung disease, including clot formation and hyper-permeability of the lung vessels, resulting in edema and bleeding into the lung. Inflammation also affects other organs, mediated by the cytokine storm. This inflammation is characterized by endothelial cell […]

Spike Proteins, COVID-19, and Vaccines


A new study further elucidates the role of spike proteins in COVID-19. Authors: Steven Novella  May 5, 2021 A recent study looks at the effects of the SARS-CoV-2 spike proteins, showing that they can cause some of the harm of COVID-19 by themselves. This is an important advance in our understanding of the disease and hopefully […]

DOD medical data reveals surges in oft-cited vax ‘adverse events’ in 2021


Three military doctors say medical billing code data captured by Defense Medical Epidemiology Database shows sharp spikes in miscarriages, myocarditis, cancer diagnoses, Bell’s palsy, female infertility. According to the data found by the military doctors, there was also a nearly 300% increase in cancer diagnoses, from a 38,700-per-year average in 2016-2020 to 114,645 in 2021. […]

Pandemic health consequences: Grasping the long COVID tail


Authors: Kieran L. Quinn , Chaim M. Bell Published: January 25, 2022 Emerging evidence suggests that approximately 10% of people who survive Coronavirus Disease 2019 (COVID-19) will have lingering symptoms that negatively affect their quality of life, ability to work, and function [1,2]. This important group of people with the post-COVID-19 condition may seem small in comparison […]

Antibody dependent enhancement: Unavoidable problems in vaccine development


Authors: Lele Xu, Zhiqian Ma, Yang Li, Zhaoxia Pang, and Shuqi Xiao* Adv Immunol. 2021; 151: 99–133.Published online 2021 Sep 4. doi: 10.1016/bs.ai.2021.08.003 PMCID: PMC8438590PMID: 34656289 Abstract In some cases, antibodies can enhance virus entry and replication in cells. This phenomenon is called antibody-dependent infection enhancement (ADE). ADE not only promotes the virus to be recognized by the target cell and enters the target […]
