The kinetics of T lymphocyte subpopulations in guinea-pigs sensitized with allogeneic transplantation antigens. 1980

G A Hashim, and N Yee, and W G Ramey

The kinetics of specifically sensitized T lymphocytes in the circulation and lymphoid tissues of guinea-pigs immunized with allogeneic transplantation antigens or with synthetic peptide sequence known to induce delayed-type hypersensitivity were documented by the antigen-stimulated active rosette-forming T cell (AgARFC) assay. The results show that immunologically functional cells sensitized to a particular antigen do not remain in the circulation when the antigenic source has been withdrawn. These cells become sequestered in lymphoid tissue and may be recalled into the circulation shortly after the de novo administration of sensitizing antigen. The detection of antigen-sensitive T cells in the circulation was indicative of the presence of and failure to detect these cells and their eventual appearance in lymphoid tissues was related to depletion of the antigenic source.

UI	MeSH Term	Description	Entries
D006968	Hypersensitivity, Delayed	An increased reactivity to specific antigens mediated not by antibodies but by sensitized T CELLS.

D007111	Immunity, Cellular	Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

D007958	Leukocyte Count	The number of WHITE BLOOD CELLS per unit volume in venous BLOOD. A differential leukocyte count measures the relative numbers of the different types of white cells.

D008198	Lymph Nodes	They are oval or bean shaped bodies (1 - 30 mm in diameter) located along the lymphatic system.	Lymph Node,Node, Lymph,Nodes, Lymph
D006168	Guinea Pigs	A common name used for the genus Cavia. The most common species is Cavia porcellus which is the domesticated guinea pig used for pets and biomedical research.	Cavia,Cavia porcellus,Guinea Pig,Pig, Guinea,Pigs, Guinea
D006649	Histocompatibility Antigens	A group of antigens that includes both the major and minor histocompatibility antigens. The former are genetically determined by the major histocompatibility complex. They determine tissue type for transplantation and cause allograft rejections. The latter are systems of allelic alloantigens that can cause weak transplant rejection.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D012397	Rosette Formation	The in vitro formation of clusters consisting of a cell (usually a lymphocyte) surrounded by antigenic cells or antigen-bearing particles (usually erythrocytes, which may or may not be coated with antibody or antibody and complement). The rosette-forming cell may be an antibody-forming cell, a memory cell, a T-cell, a cell bearing surface cytophilic antibodies, or a monocyte possessing Fc receptors. Rosette formation can be used to identify specific populations of these cells.	Immunocytoadherence,Formation, Rosette,Formations, Rosette,Immunocytoadherences,Rosette Formations
D013154	Spleen	An encapsulated lymphatic organ through which venous blood filters.
