The effects of cyclosporin A on the generation and revelation of B memory cells by thymus-independent (TI) antigens was investigated. A class 1 (TNP-LPS) and a class 2 (TNP-Ficoll) TI antigens were used for priming an elicitation. Evidence is presented that cyclosporin A does not interfere with the generation of hapten-specific (TNP) B memory cells by TNP-LPS or DNP-Ficoll. Cyclosporin A does not affect the revelation of B memory cells by TNP-LPS, but inhibits their revelation by TNP-Ficoll. These findings are discussed in terms of two distinct B cell lineages leading to antibody-forming cells and memory cells precursors, and in terms of heterogeneity of B memory cells.

UI	MeSH Term	Description	Entries
D007156	Immunologic Memory	The altered state of immunologic responsiveness resulting from initial contact with antigen, which enables the individual to produce antibodies more rapidly and in greater quantity in response to secondary antigenic stimulus.

D008070	Lipopolysaccharides	Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed)	Lipopolysaccharide,Lipoglycans
D008810	Mice, Inbred C57BL	One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D008815	Mice, Inbred Strains	Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations, or by parent x offspring matings carried out with certain restrictions. All animals within an inbred strain trace back to a common ancestor in the twentieth generation.

D003524	Cyclosporins	A group of closely related cyclic undecapeptides from the fungi Trichoderma polysporum and Cylindocarpon lucidum. They have some antineoplastic and antifungal action and significant immunosuppressive effects. Cyclosporins have been proposed as adjuvants in tissue and organ transplantation to suppress graft rejection.	Cyclosporines
D005362	Ficoll	A sucrose polymer of high molecular weight.
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.
