Cancer immunotherapies, including cancer vaccines, harness and amplify the immune system’s natural ability to detect and attack cancer cells. In this illustration, immune T cells (pink) attach to a ...

The immune system can work in two ways: the innate immune system reacts to any foreign invaders that are identified by immune cells that look for such pathogens; but the acquired or adaptive immune ...

The innate response's job is to assess the threat and determine how best to handle it. When it has a firm grasp on the situation, and if it can't deal with the threat itself, the innate response ...

Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...

When a transplanted organ arrives, it’s like a controlled burn that risks becoming a wildfire. The body’s innate immune system senses damage signals, like heat shock proteins (HSP70), and sounds the ...

Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease characterised by the production of autoantibodies and the formation of immune complexes, leading to inflammation and multi-organ ...

Researchers have discovered a protein variant that serves as a knob for regulating the body's innate immune response. The findings could lead to new therapies for Long COVID, autoimmune disorders, and ...

Researchers have shown that innate immune training, also known as trained immunity (TRIM), leads to aggravated bone loss in experimental models of periodontitis and inflammatory arthritis. Clinical ...

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

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 ...
