In BALB/c mice with AD induced by ovalbumin (OVA), treatment with superoxide dismutase 3-transduced MSCs (SOD3-MSCs) suppressed the recruitment of T cells into the skin and reduced the number of CD4+ and CD8+ T cells in the spleen and lymph node (Sah et al., 2018). The gene discussed is SOD3; the disease is Alzheimer disease.
