Expression of HLA-DO in a class II+ and DM+, DO- human T cell line caused the accumulation of class II- CLIP complexes , indicating that HLA-DO blocked DM function in vivo and suggesting that HLA-DO is an important modulator of class II-restricted antigen processing .
 ( cell line: class II+ and DM+, DO- human T cell line, None) , ( protein: HLA-DO, None) , ( protein: HLA-DO, None) , ( protein: class II- CLIP complexes, None) , ( protein: HLA-DO, None)
