**Background of Recombinant Human HLA-C Protein**
Human leukocyte antigen C (HLA-C) is a class Ia major histocompatibility complex (MHC) protein critical for immune regulation. It presents antigenic peptides to CD8+ T cells, enabling immune surveillance against infected or malignant cells. Unlike HLA-A and HLA-B, HLA-C exhibits lower cell surface expression but plays a unique role in modulating natural killer (NK) cell activity through interactions with killer-cell immunoglobulin-like receptors (KIRs). This interaction influences outcomes in transplantation, pregnancy, and autoimmune diseases.
Recombinant HLA-C proteins are engineered using molecular cloning techniques, typically expressed in mammalian or bacterial systems to ensure proper folding and post-translational modifications. These proteins retain the α1. α2. and α3 domains of the heavy chain, often combined with β2-microglobulin and specific peptides to stabilize the structure.
Research applications include studying antigen presentation mechanisms, HLA-KIR interactions in reproductive immunity, and associations between HLA-C polymorphisms and diseases like HIV progression or cancer immune evasion. In therapeutics, recombinant HLA-C aids in developing immunotherapies, vaccines, and tools for HLA typing in transplant compatibility. Its structural analysis also advances understanding of alloreactivity and peptide-binding specificity, bridging gaps in personalized medicine and immune-related disorder treatments.
Overall, recombinant HLA-C is pivotal for dissecting immune pathways and designing targeted clinical interventions.
