In both cases the treated mice had enlarged spleens and increased spleen T cell numbers, lower percentages of suppressor cell subsets (conventional CD4+CD25+ Treg, CD4+CD25−DX5+ Tr1, CD8+DX5+, CD4+CD28−, CD8+CD28−), changed proportions of Tcm and Tef/Tem T cells in the spleen and increased amount of tumor cell specific antibodies in the sera. Here, CD8A is linked to neoplasm.
