A protein made by gut cells helps to destroy harmful bacteria in the intestines, according to experiments in mice 1. Roughly 50 proteins in the blood make up the complement system, which forms a ...

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 ...

Researchers have shown that certain plant proteins resemble human signaling proteins of the immune system and can bind to their receptors. The human immune system is based on cells that communicate ...

Swiss scientists have identified immune system abnormalities in patients with long COVID that might open the door to new diagnostic tests and treatments. The researchers found that a group of proteins ...
