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. Immune 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 … csf collection in rats

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.

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 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.

WebMay 1, 1997 · Taking into account these particularities, the design of effective vaccines for neonates poses significant difficulties. We hypothesized that a continuous exposure to low doses of antigens may avoid high-zone tolerance and may lead instead, to effective expansion of effector and memory cells.
