Pentraxin family proteins are central humoral components of the innate immune system. They comprise short pentraxins such as C-reactive protein (CRP) and serum amyloid P component (SAP), and long ...

Innate lymphoid cells, which curiously behave like T cells even though they don’t recognize specific antigens, show promise as a potential cancer therapeutic. In the years that followed, other groups ...

SARS-CoV-2 has an enzyme that can counteract a cell's innate defense mechanism against viruses, explaining why it is more infectious than the previous SARS and MERS-causing viruses. The discovery may ...

Our immune system is divided into two main branches: innate and adaptive. Innate immune cells act as a first line of defense, quickly responding to invaders, while adaptive immune cells take a longer ...

Unlike transient innate immune activation, trained immunity is characterized by long-lasting but reversible functional reprogramming of monocytes, macrophages, natural killer (NK) cells, and ...

Researchers have discovered that mRNA-based COVID-19 vaccines have a persistent effect on the innate immune system. These mechanisms may help the human body to better protect itself against potential ...

Secondary infections caused by bacteria or viruses during hospital care remain a long-standing global challenge, despite advances in modern medicine. In particular, mixed bacterial–viral infections in ...

Our immune system is much older than we think. Long before dinosaurs existed, early life forms had developed a powerful ...
