adaptive immune response

[ə¦dap·tiv i′myün ri‚späns]
(immunology)
An immune response based on the principle of clonal recognition, such that upon first exposure to an antigen, primed lymphocytes either differentiate into immune effector cells or form an expanded pool of memory cells that respond to secondary exposure to the same antigen by mounting an amplified and more rapid response.

This new patent further validates the role of ResistAid larch arabinogalactan as an immune modulation ingredient, thanks to a wealth of validated science demonstrating its ability to selectively call upon both the non-specific, cellular response, as well as the adaptive immune response in healthy adults," said Bryan Rodriguez, global product manager for Lonza.
In the mouse experiment, similar damage to infected human hepatocytes was seen, which validates the theory that the adaptive immune response (T and B cells) was insignificant in the disease process.
The immune system has classically been divided into two compartments: (i) adaptive immune responses (T- and B-cells), which provide long-lived immunity to specific antigens, and are boosted through specific re-exposure to antigen, and (ii) innate immune responses (dendritic cells, phagocytes, natural killer cells), which are first to act upon exposure to a foreign antigen, and have been considered as 'nonspecific' and lacking the potential for memory of prior antigenic exposures (these features have been challenged by recent findings of NK cells in mouse models (13)).
Their main role is to capture, ingest, and process antigens in order to present them on their surface to cells of the adaptive immune response (i.
Moreover, Macrophage is an Antigen Presenting Cell which activates adaptive immune response (Henry&Albert,2008),(Paul,2008),and Mast Cell belongs to the family of Basophil, Neutrophil and Eosinophil and present near the boundaries between the body and the outside world.
One can conclude that HPV efficiently evades the innate immune response and delays the activation of the adaptive immune response but eventually the defences are activated the infection is controlled and immune memory to that specific HPV type is established.
The final chapters turn to the fields of medicine and immunology and cover human microflora and nonspecific host defenses, the adaptive immune response, microbial pathogenesis, microbial diseases, antimicrobial chemotherapy, and clinical microbiology and epidemiology.
In test-tube experiments, the scientists confirmed earlier reports that platelets can make a surface protein, called CD154, that regulates the adaptive immune response.
The innate immune response provides the body with a general first line of defense against pathogens, while the adaptive immune response endows the immune system with long-lasting and protective memory in preparation for future assaults by the same antigen.
Dendritic cells typically undergo a process called 'maturation' when they're infected by a virus - they change shape and present antigens on their surface that tell T-cells to attack that particular virus, thus generating an adaptive immune response," said UTMB professor Alexander Bukreyev, senior author of a paper on the discovery.
Cell-mediated response: Any immune response mediated by the actions of immune cells rather than molecules secreted by these cells; sometimes more specifically used to refer to any adaptive immune response in which antigen-specific T-cells have the main role.
Mature DCs relocate to the lymph nodes where they produce inflammatory cytokines and there is development of adaptive immune response which includes helper (CD4+) T-cells, cytotoxic (CD8+) T-cells, [gamma][delta] T-cells and the production of interferon [gamma] (IFN[gamma]) and tumour necrosis factor [alpha] (TNF[alpha]), both key cytokines in immunity to tuberculosis.
