Give scientific reasons: Virus-infected cells provide innate immunity to other cells.
(N/A) Virus-infected cells release proteins called interferons. These interferons are secreted into the extracellular space and bind to receptors on neighboring,uninfected cells. This binding triggers the uninfected cells to produce antiviral proteins that inhibit viral replication,thereby protecting them from further viral infection. This mechanism is a component of cytokine-mediated innate immunity.
