By using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), we investigated the difference in the HLA class II molecule between HLA-Dw2 and Dw12, both of which are typed as HLA-DR2 serologically. The anti-HLA-DR framework monoclonal antibody (MoAb) HU-4 precipitated an α-chain and two β-chains of human class II molecules from both Dw2 and Dw12 homozygous B lymphoblastoid cell lines. It was demonstrated clearly that an α-chain (α1) and one of the β-chains (β1) showed no difference in mobility in the 2D-PAGE between Dw2 and Dw12, but that another β chain (β2) of Dw2 was distinct from that of Dw12 in the 2D-PAGE profile. Thus, MoAb HU-4 precipitated α1β1 and α1β2 molecules from Dw2 and Dw12, and the α1β1 molecule appears to be an HLA-DR2 molecule. The α1β2 molecule, on the other hand, is a class II molecule distinct from those precipitated with anti-DR2, anti-DQw1 (DC1, MB1, MT1), or anti-FA MoAbs. MoAb Hu-4 completely inhibited the mixed lymphocyte culture reaction (MLR) between Dw2 and Dw12, but anti-DR2 MoAb HU-30, which reacts only with the α1β1 molecule, did not show an inhibitory effect on the MLR between DW2 and Dw12. The α1β2 molecule is therefore the molecule which elicits MLR between Dw2 and Dw12. An IL 2-dependent T cell line established from an HLA-Dw12/D blank heterozygous high responder to the streptococcal cell wall antigen (SCW) clearly distinguished the Dw2 specificity from Dw12 specificity expressed on the antigen-presenting cell (APC). Moreover, MoAb HU-4 markedly inhibited the cooperation between the T cell line and APC to respond to SCW. These observations indicate that the α1β2 is recognized as a restriction molecule by the T cell line at the antigen presentation of SCW through APC. MoAb HU-30 on the other hand partially inhibited the MLR between Dw2 or Dw12 homozygous cell as a stimulator cell and non DR2 cell as a responder cell. It markedly inhibited the proliferative response of the DW12/D- heterozygous T cell line to SCW, presented by Dw2+ but Dw12- allogeneic APC, and the peripheral response of Dw2 or Dw12 homozygous peripheral blood lymphocytes to SCW. Thus, two distinct class II molecules encoded by the genes within the HLA-DR subregion of HLA-Dw2 and Dw12 can act as stimulating molecules in the MLR and as restriction molecules in the antigen presentation by APC.
