P. C. L. Beverleycreasing complexity are built up by introducing a succession of structures such as differentiable maps, fiber bundles, differential forms, connections and metrics. Without disputing that there are good reasons for this approach, we wish to point out that it has some serious practical drawbacks. To b

Expansion, Selection and Maintenance of Memory B-Cell Clones,erties of a secondary (or memory) response that differ from a primary response, i.e. the kinetics of a secondary response are accelerated, the isotype of antibody produced is different (relatively more IgG or IgA compared with IgM) and the affinity of the antibody produced is increased. However, at

The Generation of B-Cell Memory: A Working Hypothesis,genic stimulation leads both to a selective increase in the frequency of B cells responsive to the immunizing antigen and to the generation of a population of cells (secondary B cells) that are phenotypically and functionally distinct from primary B cells specific for the same antigen.

Antiviral T-Cell Memory?,100 years that the persistence of high antibody titers (Fig. 1) can be lifelong after viral infections and that delayed-type hypersensitivity can be demonstrated for a long time by challenging with a protein antigen after prior infection with tubercle bacilli. The concept of providing protection fro

Subsets of Rat CD4+ T Cells Defined by Their Differential Expression of Variants of the CD45 Antiges helper or inducer cells for B cells, macrophages, bone marrow cells and other T cells. In addition, the lymphokines that they produce have been shown to act not only on leucocytes but also on non-bone marrow derived cells. This wide range of T-cell functions has only recently been fully appreciate
