HLA-C encodes a classical MHC class I heavy chain that pairs with β2-microglobulin to present endogenously derived peptides at the cell surface, enabling CD8+ T cell surveillance. In addition to antigen presentation, HLA-C serves as a dominant ligand for inhibitory and activating killer cell immunoglobulin-like receptors (KIRs), shaping natural killer (NK) cell education and cytotoxic thresholds. Through these immune recognition processes, HLA-C integrates with interferon-driven antigen processing and presentation pathways, including proteasomal peptide generation and TAP-dependent loading in the endoplasmic reticulum. Genetic variation and altered expression of HLA-C are linked to immune-mediated and inflammatory disease susceptibility and influence host–pathogen interactions, making it a key locus for mechanistic studies of immune regulation.
HLA-C Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the HLA-C locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within HLA-C. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt HLA-C function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of HLA-C-disrupted clones.
