A new analysis of lung epithelial cells from COVID-19 patients reveals how the protective complement branch of the immune system, which usually plays roles in both innate and adaptive immunity, can ...

Our immune system is armed with an array of defenses designed to detect and eliminate harmful threats. One of its most powerful defense mechanisms is the complement system-a group of proteins that ...

Undertaking a study of proteins found in the complement system, an important part of the immune system, of patients with long COVID, researchers have identified a blood protein ‘signature’ that may ...

Faults in a certain part of the immune system might be at the root of some long covid cases, new research suggests. For many people, covid is an illness that blusters in and out of our lives as cases ...

The complement system is a key component of innate and adaptive immunity and therefore acts as a vital defense against invading pathogens. Deficiencies in the complement system are associated with ...

Most people infected with the SARS-CoV-2 virus recover after the acute illness. However, a significant proportion of infected individuals develop long-lasting symptoms with a wide range of ...

Researchers in the United States have conducted a study showing that activation of the complement system is specifically implicated in the pathogenesis of severe coronavirus disease 2019 (COVID-19), ...

The complement system is designed to kill pathogens through a signal cascade that results in cell lysis, removal of the pathogens through phagocytosis, and alerting other immune system cells to help ...

The story of Q32 Bio, a company that develops therapeutics for inflammatory and autoimmune diseases, started two decades ago. That's when V. Michael Holers, MD, a University of Colorado School of ...

Changes to serum proteins could be behind the debilitating condition known as long COVID. The findings, published in the journal Science, could pave the way for diagnosing and treating the disease.
