Interferons alpha and beta help the host in defense against viral infections by:

Question

Quizplus · Accepted Answer

Interferons alpha and beta are cytokines that are produced in response to viral infections. They bind to specific receptors on neighboring cells, inducing the expression of antiviral proteins that inhibit viral replication. This helps limit the spread of the virus and contributes to the host's defense against the infection. Interferons do not directly enhance antibody production or stimulate cytotoxic T cells, although they can indirectly contribute to these responses by limiting viral replication. Toll-like receptors are a type of pattern recognition receptor that recognizes pathogen-associated molecular patterns, and while interferons can activate these receptors, this is not their primary mechanism of action in defense against viral infections.
