Emerging role of complement in COVID‑19 and other respiratory virus Diseases


Mark T. Xiao1 · Calder R. Ellsworth· Xuebin Qin,: 3 February 2024 Abstract The complement system, a key component of innate immunity, provides the first line of defense against bacterial infection; however, the COVID-19 pandemic has revealed that it may also engender severe complications in the context of viral respiratory disease. Here, we review the […]

Study points to vagus nerve dysfunction as a central pathophysiological feature of long COVID


by Emily Henderson, B.Sc.Feb 2022 News Medical Life Sciences New research to be presented at this year’s European Congress of Clinical Microbiology and Infectious Diseases (ECCMID 2022, Lisbon, 23-26 April) suggests that many of the symptoms connected to post-COVID syndrome (PCC, also known as long COVID) could be linked to the effect of the virus on […]

COVID-19 Can Remain Undetected In Lungs For 18 Months: Study


DEC 14, 2023 – Authored by Amie Dahnke via The Epoch Times  The COVID-19 virus can remain in the lungs for months after an individual has been infected—even though it may be undetected by over-the-counter (OTC) tests, a new study finds. The findings, established by a research team from the Institut Pasteur in France and […]

New research points to possible reason for long COVID


A Spanish study suggests that SARS-CoV-2 mediated vagus nerve dysfunction (VND) could be responsible for long COVID. By SHIRA SILKOFF, FEBRUARY 2022 – The Jerusalem Post Many symptoms of post-COVID syndrome could be caused by lasting damage sustained to one of the most important nerves in the human body during initial infection with coronavirus, new research has […]

Runaway immune reactions cause long COVID breathing problems


Author: Christopher Vaughan, Stanford Medicine 2023 Stanford Medicine researchers have found a mechanism behind one of the most common symptoms of long COVID — shortness of breath. Post COVID-19 breathing problems are caused by a condition known as lung fibrosis, when damaged lungs form scar tissue, which makes it difficult for lungs to expand and […]
