Select the INCORRECT statement w.r.t interferons. (a) Synthesized by uninfected host cells that are susceptible to viral infection. (b) They can be used to destroy the tumour. (c) α - interferons are secreted by virus infected cells . (d) They are categorised under cytokinin barrier of innate immunity.
