Complement component 3, often called C3, is an essential protein of the immune system. This protein plays a vital role in the body’s innate immune system, providing: the first line of defense against ...

Scientists discovered how macrophages, which act as the immune system's first line of defense, tailor their specific responses to various intruders through the independent and cooperative functions of ...

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 ...

Researchers at the Medical University of Vienna and the Medical University of Innsbruck discovered that SARS-CoV-2 hijacks three important host proteins that dampen the activity of the complement ...

Scientists have found a way to supercharge the immune system’s T cells by blocking a protein called Ant2, essentially rewiring how these cells generate energy. This metabolic reprogramming makes them ...

Complement 3 glomerulopathy (C3G) is a rare kidney disease that affects your body’s innate immune system (complement system). Complement 3 glomerulopathy (C3G) is a kidney disease that’s caused by ...

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 ...

Long Covid has long eluded scientists looking for its cause. Not knowing what triggers its persistent and distressing symptoms makes the condition challenging to treat; it’s hard to even say ...
