Peripheral blood lymphocyte subsets in patients with symptomatic epilepsy (SE) were evaluated by flow cytomentry before (n=32) and after (n=12) first course of cellular therapy using autologous mesenchymal stem cells (autoMSCs). ItwasshownthatpatientsrevealedhighercontentofCD3+CD16+CD56+ NKT cells and TcRγδ+cells as well as lower content of CD3+CD4+ T cells when compared to healthy control subjects. After 6-7 days post starting of cellular therapy with autoMSCs in peripheral blood of patients with SE we detected increased up to normal content of CD3+CD4+ T cells,and decreased level of CD3+HLA-DR+ activated T cells, CD3+CD8+CD57+ cytotoxic T cells, CD3+CD8+CD45RA naïve T cells. We concluded that MSCs-based cellular therapy of patients with SE possessed direct immunomodulation upon impaired T cell subsetsĺ content in peripheral blood prior to beneficial clinical effect.
