Previous studies have indicated that LLA-DR homozygous cell lines express two DR molecules but only a single DS (I-A-like) molecule. This report demonstrates that an HLA-DR5 homozygous cell line expresses at least two distinct DS molecules. These two DS molecules are formed by the association of a single DS alpha chain with either of two DS beta chains. Four distinct Ia molecules have now been identified from this DR5 homozygous cell line.
先前的研究表明,LLA-DR纯合细胞系表达两种DR分子,但仅表达一种单一的DS(I-A样)分子。本报告证明,一种HLA-DR5纯合细胞系至少表达两种不同的DS分子。这两种DS分子是由单一的DSα链与两种DSβ链中的任意一种结合形成的。现已从该DR5纯合细胞系中鉴定出四种不同的Ia分子。
