immune response

An integrated bodily response to an antigen, in vertebrate animals including the immediate, nonspecific response of the innate immune system followed by the specific response of the adaptive immune system, which involves recognition of antigens by specific antibodies or previously sensitized lymphocytes.

immune response

(Biology) the reaction of an organism's body to foreign materials (antigens), including the production of antibodies

immune′ response`

any of the body's immunologic reactions to an antigen.

im·mune response

A response of the body to a foreign substance, called an antigen, especially a microorganism or virus that causes disease. The immune response involves the action of white blood cells called lymphocytes, which work to deactivate foreign antigens, often by stimulating the production of antibodies.
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.immune response - a bodily defense reaction that recognizes an invading substance (an antigen: such as a virus or fungus or bacteria or transplanted organ) and produces antibodies specific against that antigen
response, reaction - a bodily process occurring due to the effect of some antecedent stimulus or agent; "a bad reaction to the medicine"; "his responses have slowed with age"
anamnestic reaction, anamnestic response - renewed rapid production of an antibody on the second (or subsequent) encounter with the same antigen
humoral immune response - an immune response (chiefly against bacterial invasion) that is mediated by B cells
cell-mediated immune response - an immune response (chiefly against viral or fungal invasions or transplanted tissue) that involves T cells
complement fixation - an immune response in which an antigen-antibody combination inactivates a complement (so it is unavailable to participate in a second antigen-antibody combination)
bacteria, bacterium - (microbiology) single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission; important as pathogens and for biochemical properties; taxonomy is difficult; often considered to be plants
fungus - an organism of the kingdom Fungi lacking chlorophyll and feeding on organic matter; ranging from unicellular or multicellular organisms to spore-bearing syncytia
complement - one of a series of enzymes in the blood serum that are part of the immune response

In-depth understanding of innate immune responses to protozoa is important because their genomic complexity affords them a greater variety of immune evasion mechanisms than those displayed by prokatyotes.
Though antiretroviral therapy has enabled immunologic control of HIV and viral suppression, the use of HAART is associated with decreased HIV-specific immune responses, particularly in patients with chronic HIV infection.
These two signaling molecules bind to the same docking sites on cells, but CD28 enhances immune responses whereas CTLA-4 slows them, says Jeffrey A.
This could work because HIV seems to cause most of its damage indirectly--by the toxic tat protein, for example, or by dysregulation of immune responses leading them to kill normal cells--rather than by killing infected cells, which the body could normally replace.
In advancing to human tests, Levy's team conducted a pilot study that was primarily intended to monitor immune responses in four patients and to determine the therapy's safety.

The results demonstrated that T-cell vaccination was well tolerated and, importantly, induced T-cell regulatory immune responses which collectively correlated with substantial clinical improvement in treated patients.
Therefore, based on the promise of heightened immune responses in the presence of viremia in some patients (as measured by these cytokine assays), some thought that perhaps a good strategy to bolster HIV immunity would be to provide an opportunity for small, controlled quantities of HIV to be made--ostensibly to provide antigen and to drive the immune response.

In this laboratory, the approach we have taken has been to examine the characteristics of immune responses induced in mice following parenteral (intraperitoneal) exposure to test proteins.
