Interferons: Types, Chemical Nature, Properties and Mechanism of Action

Introduction to Interferons Interferons are low molecular weight protein, produced by virus infected cells. These, itself induces the formation of a second protein inhibiting the transcription of viral mRNA. These are produced by the host cell in response to the virus particle, viral nucleic acid and non-viral agents. Non-viral agents include synthetic polynucleotides such as … Read more
