Abstract

The differential effect of 2-mercaptoethanol (2-ME) on spleen and bone marrow cells of young and old mice was determined in vitro. Both the ability of spleen cells to proliferate and to generate Ig-secreting cells and the capacity of bone marrow cells to generate myeloid colonies were assessed. All three activities assessed in both young and old mice were enhanced by the presence of 2-ME, but a differential effect with respect to age was noted in only one. This was the polyclonal activating antibody response to bacterial lipopolysaccharide (LPS) in which 2-ME enhanced young spleen cells to a greater extent than old spleen cells, although their mitogenic responses to LPS were enhanced to the same extent. The ability of 2-ME to enhance old spleen B cells to proliferate but not differentiate in their response to LPS would suggest that aging alters certain subpopulations of spleen cells, some of which are sensitive and others insensitive to the potentiation effects of 2-ME. The enhancing action of 2-ME on the proliferative activity of LPS-stimulated young spleen cells was reduced drastically by decreasing the number of T cells by prior treatment of spleen cells with anti-T cell reagent. The proliferative activity was then brought b...Continue Reading

B cell Differentiation

Depending on the signal received through the B cell receptor and other receptors, B cells differentiate into follicular or marginal zone B cells. Here is the latest research pertaining to this differentiation process.
