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.

We also found that the adaptive immune response is quite active in human RUTIs," Zimmern added.
The TDAR method is particularly useful, as although the final end point is the assessment of antibody responses, and therefore serves as a measurement of the humoral response, effective T cell function is also required to support this, and the method therefore provides a mechanism for assessing the function of the adaptive immune response as a whole.
Studies have shown that patients with poor glycaemic control (glycosylated haemoglobin [HbA1c]>7%) had an increased risk of TB activation compared to patients with normal glycaemic level.24 In DM hosts, there is a delay in activation of Th1 cell-mediated immunity, leading to dysfunction in the adaptive immune response.28 In co-morbid TB-DM patients, increased levels of Th1 and Th17 cytokines are found.32 The efficacy of the Th1 response is reduced by impaired cellular interactions and the inability to mount a response during infections in DM hosts.
Increased sebum production results in proliferation of Propionibacterium aeries, and the attendant lipase catalysis of triglycerides to the free fatty acids palmitic and oleic acid, leading to inflammasome activation.The latter, plus IL-1-beta upregulation and subsequent adaptive immune response activation, leads to development of inflammatory papules, pustules, and nodules.
Interferon produced by infected epithelial cells is important for the activation of the adaptive immune response [10, 16].
Dendritic cells (DCs), bone-marrow-derived leukocytes, are the most efficient antigen-presenting cells due to their ability to capture, process and present these antigens to T lymphocytes, thus regulating the adaptive immune response by activating T lymphocytes as antigen-presenting cells.
The release of TNF-[alpha] in animal models is a part of the adaptive immune response. When an antigen is injected into the mouse inner ear, both IL-1[beta] and TNF-[alpha] are secreted and a normal immune response occurs.
Activated by bacteria, all of these mechanisms determine a proinflammatory adaptive immune response that involves several T cell subpopulations, such T helper 1 and 17 (Th1 and Th17 cells), and their related cytokines, such as IL-1, IL-2, IL-15, IL-17, IL-22, and IL-23 [10].
Mincle, Dectin-1, and Dectin-2 Agonists Induce Strong Cellular Adaptive Immune Response In Vivo.
Altered processing of gliadin by intraluminal enzymes, intestinal permeability changes, and activation of the innate immune system precede the adaptive immune response observed in established CD.
Each group was divided into five times observations in the 2nd, 4th, 6th, 8th and tenth day towards the adaptive immune response in the form of levels of Interferon Gamma (IFN[gamma]) using ELISA and the number of T-helper cells ([CD4.sup.+]) by immunohistochemical methods.
The two ways of defense of an immune mechanism involving short-term mechanism which is the first line of defense and the other highly advanced adaptive immune response marked by complexity, diversity, and memory.
