CD86 (B7-2) is a co-stimulatory immunoregulatory ligand expressed primarily on antigen-presenting cells that binds CD28 and CTLA-4 to tune T cell activation, anergy, and immune checkpoint balance. Through integration with TCR signaling, CD86 contributes to immunological synapse formation and downstream pathways including NF-κB, MAPK, and PI3K/AKT, shaping cytokine production and adaptive immune priming. Altered CD86 expression has been reported across inflammatory and autoimmune contexts and in tumor-immune microenvironments, where it can influence antigen presentation and the amplitude of lymphocyte responses. As a result, CD86 is frequently studied in assays of dendritic cell maturation, macrophage polarization, and T cell co-stimulation dynamics.
B7-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CD86 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CD86. 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 CD86 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 CD86-disrupted clones.
