Polyinosinic acid - polycytidylic acid sodium salt, often referred to as poly(I:C) sodium salt, is a synthetic analog of double-stranded RNA (dsRNA) that is widely used in research to mimic viral infection. This compound is recognized by pattern recognition receptors such as Toll-like receptor 3 (TLR3) and retinoic acid-inducible gene I (RIG-I), which play critical roles in the innate immune response. In research applications, this compound is employed to study the cellular and molecular mechanisms underlying the immune response to viral infections, including the production of type I interferons and the activation of various signaling pathways. It is also used to investigate the impact of dsRNA recognition on the induction of apoptosis, inflammatory responses, and the activation of adaptive immune responses.
