Research Abstract |
CD26 has an important role in T-cell activation and is costimulatory molecule. We demonstrated that the expression level of lipid rafts to the peripheral blood T cell surface increased over time by costimulation of CD3 and CD26. Moreover, anti CD26 antibody treatment of peripheral blood T cells led to increased surface expression of Lipid rafts. On the other hand, after costimulation under the immunosuppressive drugs treatment, the expression of lipid rafts on T cells decreases drugs concentration-dependently and over time with T-cell proliferation being inhibited. Our results suggest that lipid rafts may become the biomarker when we evaluate the effect of the immunosuppressive drug in patients with glomerulonephritis.
