Mouse Cd86 encodes the costimulatory receptor B7-2 (CD86), a type I membrane glycoprotein expressed primarily on antigen-presenting cells such as dendritic cells, macrophages, and B cells. By engaging CD28 and CTLA-4 on T cells, B7-2 integrates innate immune sensing with adaptive immune activation and tolerance, influencing IL-2 production, T-cell proliferation, and differentiation. Cd86 expression is induced by inflammatory cues including TLR/NF-κB signaling and contributes to the amplitude and quality of antigen-driven responses in lymphoid tissues. Dysregulated CD86-mediated costimulation is implicated in autoimmune and inflammatory disease mechanisms and is widely studied in models of transplant rejection, allergy, and tumor-immune interactions.
B7-2 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Cd86 locus in mouse 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.
