HLA-DP, HLA-DQ, and HLA-DR have different requirements for invariant chain and HLA-DM.
The MHC is central to the adaptive immune response. The human MHC class II is encoded by three different isotypes, HLA-DR, -DQ, and -DP, each being highly polymorphic. In contrast to HLA-DR, the intracellular assembly and trafficking of HLA-DP molecules have not been studied extensively. However, different HLA-DP variants can be either protective or risk factors for infectious diseases (e.g. he...
متن کاملT cells sensitized to synthetic HLA-DR3 peptide give evidence of continuous presentation of denatured HLA-DR3 molecules by HLA-DP
T cell clones raised against a synthetic peptide, identical to the third hypervariable region of the DR3 BI chain, were tested for secondary proliferative responses against a panel of PBLs. All seven DR3 DPw3+ stimulators could induce proliferation. DR3- DPw3+ PBLs were recognized when the synthetic peptide was added to the cultures. Inhibition studies with mAbs showed that in both cases the HL...
متن کاملKinetic analysis of peptide loading onto HLA-DR molecules mediated by HLA-DM.
The nonclassical major histocompatibility complex class II molecule HLA-DM (DM) has recently been shown to play a central role in the class II-associated antigen presentation pathway: DM releases invariant chain-derived CLIP peptides (class II-associated invariant chain protein peptide) from HLA-DR (DR) molecules and thereby facilitates loading with antigenic peptides. Some observations have le...
متن کاملHLA-DM Interactions with Intermediates in HLA-DR Maturation and a Role for HLA-DM in Stabilizing Empty HLA-DR Molecules
Major histocompatibility complex (MHC) class II-positive cell lines which lack HLA-DM expression accumulate class II molecules associated with residual invariant (I) chain fragments (class II-associated invariant chain peptides [CLIP]). In vitro, HLA-DM catalyzes CLIP dissociation from class II-CLIP complexes, promoting binding of antigenic peptides. Here the physical interaction of HLA-DM with...
