Innate Immunity is a nonspecific host defense mechanism against foreign antigens. It is the first line of defense in a host and occurs immediately or within hours after exposure. This type of immunity ...

Innate immunity constitutes the body’s first line of defence against invading pathogens. This ancient, evolutionarily conserved system is activated within minutes of encountering foreign agents, ...

Researchers have discovered that SARS-CoV-2 hijacks three important host proteins that dampen the activity of the complement system, a key component of early antiviral immunity. This significantly ...

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 ...

In a recent study published in The New England Journal of Medicine, researchers reviewed selected acute-phase proteins concerning their production, structure, and function. The advent of severe acute ...

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 ...

Humans are protected by two branches of the immune system. Innate immunity provides built-in defense against widespread characteristics of bacteria and viruses, while adaptive immunity memorizes ...

Bacillus Calmette-Guérin (BCG) is one of the world’s oldest and most widely used vaccines. It was developed in the early 20th century to provide protection from tuberculosis. Surprisingly, this ...

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.

During pregnancy, the maternal immune system must engage in a fine balancing act: maintaining tolerance to the fetal allograft while restoring innate and adaptive immune mechanisms for protection ...
