    摘要: The present invention provides a composition comprising dendritic cells loaded with hHsp60sp, which dendritic cells are from a subject and have been fixed with paraformaldehyde (PFA). The subject may suffer from an autoimmune disease. Also provided are a method for preparing the composition; recombinant human cells comprising a heterologous gene encoding a fusion protein of HLA-E and hHsp60sp or B7sp, and expressing the fusion protein on the surface of the cells; a method for determining a percentage of maximum inhibition of testing the function of the HLA-E restricted CD8+ Treg cells from a subject, determining whether HLA-E restricted CD8+ Treg cells freshly isolated from a subject are defective, or determining whether defective HLA-E restricted CD8+ Treg cells from a subject are correctable; and a method for correcting defective HLA-E restricted CD8+ Treg cells, treating type 1 diabetes (T1D), or treating multiple sclerosis (MS).
