Interferons and secondary pneumonia after influenza
By Vincent Racaniello
Now that we have discussed influenza pathogenesis in humans and the innate immune defenses, we can tackle the conclusion that type I IFN mediates the development of secondary bacterial pneumonia in mice. Secondary bacterial pneumonia occurs after the patient has begun to recover from influenza infection, and often influenza virus ...
How influenza virus inhibits early antiviral responses
By Vincent Racaniello
The fact that viruses routinely and frequently cause disease shows that our defense mechanisms are imperfect. This occurs in large part because nearly every viral genome encodes one or more countermeasures to modulate host defenses. Influenza virus is no exception. One of the viral proteins, called NS1, is particularly adept ...
Innate immune defenses
By Vincent Racaniello
In response to viral infection, many organisms mount a remarkable defense known as the immune response. This response to viral infection consists of an innate, or nonspecific component, and an adaptive, or specific defense. The innate response is considered the first line of immune defense because it is active even ...
