Abstract
Current state of interferon (IFN) research is reviewed mainly concerning the properties of IFN molecules and their production in vivo and in vitro. Through the recent upsurge of IFN research, much information has been accumulated on the chemistry of IFN molecules and on the varied actions of IFN at the cellular level, but, to understand the role of IFN in, among others, immune or inflammatory responses of the body, much effort combining different disciplines will still be needed.
