Decoding SARS-CoV-2 hijacking of host mitochondria in COVID-19 pathogenesis

Posted on | Posted on John Murphy | Leave a Comment on Decoding SARS-CoV-2 hijacking of host mitochondria in COVID-19 pathogenesis

Authors: Keshav K. Singh,* Gyaneshwer Chaubey,* Jake Y. Chen, and Prashanth Suravajhala Because of the ongoing pandemic around the world, the mechanisms underlying the SARS-CoV-2-induced COVID-19 are subject to intense investigation. Based on available data for the SARS-CoV-1 virus, we suggest how CoV-2 localization of RNA transcripts in mitochondria hijacks the host cell’s mitochondrial function to viral advantage. […]

COVID-19 is, in the end, an endothelial disease

Posted on | Posted on John Murphy | Leave a Comment on COVID-19 is, in the end, an endothelial disease

Authors: Peter Libby, Thomas Lüscher The vascular endothelium provides the crucial interface between the blood compartment and tissues, and displays a series of remarkable properties that normally maintain homeostasis. This tightly regulated palette of functions includes control of haemostasis, fibrinolysis, vasomotion, inflammation, oxidative stress, vascular permeability, and structure. While these functions participate in the moment-to-moment regulation […]

Endothelial dysfunction contributes to COVID-19-associated vascular inflammation and coagulopathy

Authors: Jun Zhang 1, Kristen M Tecson 1, Peter A McCullough 1 2 3 Great attention has been paid to endothelial dysfunction (ED) in coronavirus disease 2019 (COVID-19). There is growing evidence to suggest that the angiotensin converting enzyme 2 receptor (ACE2 receptor) is expressed on endothelial cells (ECs) in the lung, heart, kidney, and intestine, particularly in systemic vessels (small and […]

What Is a Cytokine Storm? Doctors Explain How Some COVID-19 Patients’ Immune Systems Turn Deadly

Posted on | Posted on John Murphy | Leave a Comment on What Is a Cytokine Storm? Doctors Explain How Some COVID-19 Patients’ Immune Systems Turn Deadly

Authors: Sarah Bradley The news cycle is heavily saturated with stress-inducing information about COVID-19, but one of the most worrying aspects so far has been the huge disparity in the way the novel coronavirus presents itself: Why do some people have no symptoms (or only mild ones), while others are so sick they require ventilation? There isn’t a definitive answer, but many […]

COVID-19 cytokine storm: The anger of inflammation

Posted on | Posted on John Murphy | Leave a Comment on COVID-19 cytokine storm: The anger of inflammation

Authors: Mehdi Mahmudpour 1, Jamshid Roozbeh 2, Mohsen Keshavarz 1, Shokrollah Farrokhi 3, Iraj Nabipour 4 Patients with COVID-19 who require ICU admission might have the cytokine storm. It is a state of out-of-control release of a variety of inflammatory cytokines. The molecular mechanism of the cytokine storm has not been explored extensively yet. The attachment of SARS-CoV-2 spike glycoprotein with angiotensin-converting enzyme 2 […]

Cytokine Storm in COVID-19: The Current Evidence and Treatment Strategies

Authors: Yujun Tang,† Jiajia Liu,† Dingyi Zhang, Zhenghao Xu, Jinjun Ji,* and Chengping Wen* Severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) is the pathogen that causes coronavirus disease 2019 (COVID-19). As of 25 May 2020, the outbreak of COVID-19 has caused 347,192 deaths around the world. The current evidence showed that severely ill patients tend to have a high concentration of […]

SARS-CoV-2 infection: The role of cytokines in COVID-19 disease

Posted on | Posted on John Murphy | Leave a Comment on SARS-CoV-2 infection: The role of cytokines in COVID-19 disease

Authors: Víctor J Costela-Ruiz 1, Rebeca Illescas-Montes 1, Jose M Puerta-Puerta 2, Concepción Ruiz 3, Lucia Melguizo-Rodríguez 1 COVID-19 disease, caused by infection with SARS-CoV-2, is related to a series of physiopathological mechanisms that mobilize a wide variety of biomolecules, mainly immunological in nature. In the most severe cases, the prognosis can be markedly worsened by the hyperproduction of mainly proinflammatory cytokines, such as […]

Authors: St. Jude Children’s Research Hospital The COVID-19 pandemic continues to cause significant illness and death while treatment options remain limited. St. Jude Children’s Research Hospital scientists have discovered a potential strategy to prevent life-threatening inflammation, lung damage and organ failure in patients with COVID-19. The research appeared online in the journal Cell. The scientists identified […]
