High zone tolerance immunology
WebApr 1, 1970 · It is further postulated that the affinity of antibody produced by a given cell is a function of the number of receptor sites possessed by that cell. The theory was designed to account for the phenomena of high and low zone tolerance, and to explain the variations of antibody affinity observed during the immune response. WebJul 7, 1994 · The high level of expression of class 1 HLA in renal allografts may also explain the excellent effectiveness of current immunosuppression for cell mediated alloresponses (see high zone antigen induced tolerance, [37–39]) compared to more robust DS cellular responses to low levels of class 2 HLA expression in the kidney (antigen equivalence) …

Parish Correspondence [email protected] (C.C.G.), [email protected] … WebOct 27, 2011 · One answer is low zone tolerance (LZT), which involves the repeated exposure to small doses of an antigen. At the other end of the spectrum is high zone tolerance, occurring when individuals are exposed to a high dose of an antigen. LZT is believed to be one of the main routes by which tolerance to an antigen is developed.
WebIn the course of experiments designed to investigate the process of germinal centre formation, it was found that the lymphoid tissues of mice kept in a high zone tolerance regime to either HSA or lysozyme appeared to be abnormal in many ways (l). The abnormalities affected in particular the so-called thymus-independent zones of the … WebDec 24, 2016 · Low dosage of TD antigens may induce T cell tolerance – the low-zone tolerance, while high dosage of TD antigens may induce both T- and B-cell tolerance – the high-zone tolerance. T cell tolerance usually requires about 100–10,000 times lower antigen dosage than that of B cells, and it happens very fast and persists for months to years; B ...

WebThe tolerance thresholds were established by giving a single injection of antigen in solution in saline, followed later by challenge of antigen in adjuvant. For both antigens it was possible to induce high dose tolerance, which was preceded by a zone of priming at lower doses. In neither case was low zone tolerance observed.
WebTolerance creates an obligatory pause in the vigilant immune response to determine the best course of action. The stress and energy expenditures are much smaller when the reactions of the immune system are resolved in a calm and, ordered manner, although this can impair fitness.

The tech-niques are based on the induction of an immunosuppressive state (triggered when desired, normally during the immune response that would lead to the production of unwanted/unde-sired antibodies) ultimately leading to a decrease of the response iphone bandwidthImmune recognition of non-self-antigens typically complicates transplantation and engrafting of foreign tissue from an organism of the same species (allografts), resulting in graft reaction. However, there are two general cases in which an allograft may be accepted. One is when cells or tissue are grafted to an immune-privileged site that is sequestered from immune surveillance (like in the eye or testes) or has strong molecular signals in place to prevent dangerous inflammation … orange beach parades 2023WebBasic Immunology; Computational Immunology; Immunometabolism; Immuno-Oncology; Infection; Inflammation; Neuroimmunology; Structural Immunology; Translational Immunology; Vaccines; COVID-19 Immunology Research; Research; Resources.
