Immune Response - Overview
Innate immune response
The immune system protects the body from invading disease-causing organisms, or pathogens.
immune response
A highly specific defensive reaction of the body to invasion by a foreign substance or organism; consists of a primary response in which the invader is recognized as foreign, or "not-self, ...
Immune response - Anytime a foreign object is introduced into human tissues, the immune system is designed to attack the invader.
Host immune response
The body's first line of defense against viruses is the innate immune system. This comprises cells and other mechanisms that defend the host from infection in a non-specific manner.
The immune response to most antigens produces an antiserum — a heterogeneous mixture of antibodies.
humoral immune response Binding of antigen with soluble antibody in blood serum. Also, the entire process by which the body responds to an antigen by producing antibody to that antigen.
Humoral immune response A system for the recognition of foreign substances that employs soluble antibodies to bind to and inactivate such substances.
The adaptive immune response depends on the creation of suitable peptides from foreign antigens for display on MHC molecules to T lymphocytes.
Any foreign substance, such as a virus, bacterium, or protein, that elicits an immune response by stimulating the production of antibodies. (See Antigenic determinant, antigenic switching.) Antigenic determinant.
These proteins, called glycoproteins, are important in many cell processes, including binding by receptors and eliciting an immune response. Glycoproteins are often specific cell markers.
They function in the cellular immune response. White blood cells (leukocytes) are less than 1% of the blood's volume. They are made from stem cells in bone marrow. There are five types of leukocytes, important components of the immune system.
The complement system directly kills microbes, supplements inflammatory response, and works with the immune response. It complements the actions of the immune system.
2. (Science: immunology) a substance added to a vaccine to improve the immune response so that less vaccine is needed to produce a non-specific stimulator (for example, BCG vaccine) of the immune response.
Antigenic variation is the process by which an infectious organism alters its surface proteins in order to evade a host immune response.
lymphocytes - are central to all adaptive immune responses, since they specifically recognize individual pathogens, whether they are inside host cells or outside in the tissue fluids or blood. Two categories are T and B cells.
Antigen: Any macromolecule that triggers an immune response. Antigenicity depends on the ability of the peptide fragments to be presented by the MHC molecules.
A substance that the body regards as foreign, to which it produces an immune response, very often by secretion of antibodies ...
A molecule whose shape triggers the production of antibodies (immunoglobulins) that will bind to the antigen. A foreign substance capable of triggering an immune response in an organism.

and also produced cytokines, which are biological substances that help activate other parts of the immune system. One such part is called macrophages. These macrophages act to clean up the invaders and the dead tissue after an immune response.
foreign and begin making a variety of antibodies to capture (combine with) the proteins on the surface of the foreign cell or virus. The antibody molecules attach to the invaders and tag them for destruction by other members of your immune response ...
