Type I Interferons vs Type II Interferons
(Similarities and Differences between Type I and Type II Interferons)
Interferons or INFs are glycoproteins with indirect antiviral properties. They are cytokines whose production in the cell is induced by viral infections. Interferons stimulate the synthesis of antiviral proteins in the cells which inhibit the multiplication of viral particles.
Interferons are classified into TWO categories based on their type of Receptors. They are Type I Interferons (INFα and INFβ) and Type II Interferons (INFγ). The present post describes the Similarities and Differences between Type I and Type II interferons.
Similarities between Type I and Type II Interferons
Ø Both type I and type II interferons are short glyco-proteins.
Ø Both possess indirect antiviral properties.
Ø The production of both types of interferons is triggered by viral infections.
Ø Both can elicit immunological responses in the organ.
Ø Both types operate through receptors present on the plasma membrane.
Ø Both can trigger the production of antiviral proteins.
