Viral manipulation of the host immune response
2015
Viruses are obligate intracellular parasites that require a host for essential machinery to replicate and ultimately be transmitted to new susceptible hosts. At the same time, the immune system has evolved to protect the human body from invasion by viruses and other pathogens. To counter this, viruses have developed an arsenal of strategies to not only avoid immune detection but to actively manipulate host immune responses to create an environment more favorable for infection. Here, we describe recent advances uncovering novel mechanisms by which viruses skew host immune responses through modulation of cytokine and chemokine signaling networks, interference with antigen presentation and T cell responses, and preventing antibody production.
