HLA-G encodes a non-classical MHC class I molecule with restricted tissue distribution that contributes to immune tolerance by engaging inhibitory receptors on NK cells and T cells, including LILRB1/ILT2, LILRB2/ILT4, and KIR2DL4. Through modulation of antigen presentation, cytotoxicity, and cytokine release, HLA-G shapes local immune surveillance and supports immune-privileged microenvironments such as the maternal–fetal interface. Dysregulated HLA-G expression has been associated with altered anti-tumor and anti-viral immune responses and with inflammatory and autoimmune phenotypes. Its soluble and membrane-bound isoforms make it a useful model for studying post-transcriptional regulation, alternative splicing, and immune checkpoint-like signaling.
HLA-G Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the HLA-G locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within HLA-G. 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-G 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-G-disrupted clones.
