Negative Regulation by HLA-DO of MHC Class II-Restricted Antigen Processing

Denzin, Lisa K., Sant'Angelo, Derek B., Hammond, Craig, Surman, Michael J., Cresswell, Peter·1997·Science

Abstract

HLA-DM is a major histocompatibility complex (MHC) class II–like molecule that facilitates antigen processing by catalyzing the exchange of invariant chain–derived peptides (CLIP) from class II molecules for antigenic peptides. HLA-DO is a second class II–like molecule that physically associates with HLA-DM in B cells. HLA-DO was shown to block HLA-DM function. Purified HLA-DM-DO complexes could not promote peptide exchange in vitro. 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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
