Abstract
- A study has been made of the variables concerned in allotype suppression of adult spleen cells in the adoptive transfer system. These are: SRBC (antigen) dose; the dose and timing of injection of anti-allotype serum IgG; the number of spleen cells transferred and whether these cells were taken from primed or unprimed donors. Adoptively transferred primed cells are considerably less susceptible to suppression by concomitantly injected anti-allotype serum IgG than are unprimed spleen cells. Injection of anti-allotype serum during the period after adoptive transfer, has shown that primed cells loose their susceptibility sooner (2 days) than the unprimed cells (4 days). Allotype heterozygous CBA spleen cells arc less susceptible to allotype suppression than either allotypically homozygous or heterozygous non-H-2<superscript>k</superscript> cells (H-2<superscript>b,d, or s</superscript>). Allotype suppression of the TI IgG response to DNP-Ficoll was measured 7 days after adoptive transfer of allotype-homozygous cells from both normal and nude CBA mice (unprimed). The results indicate that T cells do not play a role in the initiation of short-term allotype suppression in the adoptive transfer system. [ABSTRACT FROM AUTHOR]
