Viruses and Toll-like receptors.

Abstract

Recently a number of viruses, including a poxvirus, herpesvirus, retrovirus and two paramyxoviruses, have been shown to activate cells via Toll-like receptor family members. Here we postulate that although activation via Toll-like receptor molecules can lead to anti-viral innate immune responses, in some cases viruses may use these responses to ameliorate infection.
