Interference

INTERFERENCE
  • It is the prevention of virus multiplication. It is due to defective interfering particles or interferons. Interferons are proteins secreted by cells in response to virus infection.
  • The trigger for interferon production is double stranded RNA produced during RNA virus replication. Inferferons protect adjacent cells from infection and activate T cell mediated immunity.
  •  There are number of types of interferons. Alpha and beta are produced by most cells when infeted with viruses. The secreted interferon diffuses to nearby cells and bind to interferon receptors and trigger antiviral activities.
