Major histocompatibility complex, class II, DR beta 1 chain (HLA-DRB1*10:01) (HLA-DR10)

Target
HLA-DR10
Molecular classification
Receptor (specifically, cell surface glycoprotein), Major histocompatibility complex class II molecule, Antigen-presenting molecule
01

Overview

HLA-DR10 refers to a specific serotype and protein of the human leukocyte antigen (HLA) system, belonging to the class II major histocompatibility complex (MHC) family. It is comprised of an alpha and beta chain (with DRB1*1001 as the defining beta chain), and is expressed on antigen-presenting cells such as B lymphocytes. HLA-DR10 presents exogenous peptide antigens to CD4+ T helper cells, which is essential for adaptive immune responses. The DR10 serotype is implicated in predisposition to certain autoimmune and malignant diseases, and has been experimentally targeted using antibodies (such as Lym-1) and synthetic peptide-like ligands. HLA-DR10 is notable for its high polymorphism and immunological specificity

02

Mechanism of action

Antibody-mediated recognition and targeted delivery (e.g., Lym-1 and SHALs bind specifically to HLA-DR10 on B-cell lymphoma cells, triggering immune destruction or facilitating targeted delivery of cytotoxic agents)

03

Biological functions

Immune response: presents exogenous peptide antigens to CD4+ T helper cells to trigger and modulate adaptive immunity
04

Disease associations

InfectionAutoimmunity (linked to susceptibility, e.g., lichen planus, rheumatoid arthritis)Cancer (notably ovarian cancer and squamous cell cervical cancer)
05

Safety considerations

Off-target immune activation (potential immunogenicity when targeting HLA-DR10 systemically)Polymorphism leading to variable expression and binding among individuals
06

Interacting drugs

Lym-1 (an antibody used in research and sometimes radioimmunotherapy against cells expressing HLA-DR10)

Biomarkers

HLA-DR10 expression is a biomarker for certain B-cell lymphomas (such as those derived from Raji cells), and may be used for diagnostic or prognostic purposes
