Abstract:
A modified method has been elaborated for induction of delayed type hypersensitivity (DH) in CBA mice with the use of Evans blue (EB) as adjuvant. This model permitted studying the mechanism of DH development, establishing the dependence of DH on the dose of EB, the dose and type of protein antigen, and realizing passive transfer of DH with the aid of splenocytes from active-synthesized mice. EB is a convenient and effective adjuvant for induction and study of the mechanism of DH development.

Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
