When a virus attacks, the body’s immune response has two basic layers of defense: the innate and the adaptive immune systems. While the adaptive immune system grows stronger against a specific ...

While the innate immune response is immediate, the adaptive immune response is not. However, the effect of the adaptive immune response is long-lasting, highly specific, and is sustained long-term ...

Immunity Unlike the broad attack of the innate defense system, the adaptive immune system attacks pathogens with specific, made-to-order antibodies and cells.

These cells are thought to play an important role in the maintenance of homeostasis in tissues, and can limit immune responses so they don't take on pathological, autoimmune characteristics. The ...

For decades, dogma dictated that the immune system consisted of two separate branches. Cells of the innate system respond rapidly to molecular patterns shared by a broad array of pathogens. Meanwhile, ...

In a session titled, Better meeting the needs of people living with HIV, health experts reminded us that science, care, and ...

Inflammation and increased mucus production are typical symptoms of worm infections and allergies. This immune response involves our innate immune cells, but their exact functions are not yet ...

Innate immune cells present signals on their surface, which adaptive immune cells recognize and become active in response. Therefore, both immune responses work together to provide a protective immune ...

The first thing that comes to mind with the word trained immunity is the immunological training every immune cell acquired during the entire lifespan of an ...

The immune system has two main arms: innate and adaptive. The innate immune system recognizes broad molecular patterns, such as molecules that certain RNA viruses generate as they replicate. It is ...

What keeps some immune systems youthful and effective in warding off age-related diseases? In a new paper published in Cellular & Molecular Immunology, USC Stem Cell scientist Rong Lu and her ...

Redefining immune memory The human immune system has two lines of defense. The innate immune system acts quickly and non-specifically to detect and fight infections; the slower, adaptive immune ...
