We then tested if MT has the ability to block the chemotactic effects of SDF-1α on these cells and found that preincubation of cells with MT inhibited the effect of SDF-1α on cell migration (Figure 3(c)), suggesting that MT may alter the movement of protective CXCR4+ T cells in T1D. The gene discussed is CXCR4; the disease is type 1 diabetes mellitus.
