产品描述： Biochem/physiol Actions Transfection of Poly (I:C) into NIT-1 cells has been used as a model of intracellular dsRNA-induced β cell

apoptosis. Eighteen hours post transfection, 45% of the cells were apoptotic with an increase in NF-kB,

p50/p65 nuclear translocation, and cleavage of caspases 3 and 8, as well as transcriptional induction of

caspase 12, Fas, IL-15, and the TNF receptor-associated ligand (TRAIL). It has been suggested that

Poly(I:C) is one of the most appropriate generators of stable mature dendritic cells (DC). These mature DC

might generate in vivo effective immune responses after injection due to their ability to secrete bioactive IL-12

after CD40 ligation. Poly (I:C) was used as a potent adjuvant to enhance the specific anti-tumor immune

responses against a peptide-based vaccine.
