Abstract
In this chapter the cytokine molecules and pathways present in teleost fish are described, with a focus on the different types of immunity with which they are associated. Whilst there are many molecules conserved between teleosts and mammals, differences do exist. Some novel cytokines are present, some absent (evolved later?) and often multiple copies/paralogues are found due to the extra rounds of whole-genome duplication that have occurred relative to most other vertebrates. In each section the cytokines present in zebrafish are outlined first, since this is an important model species that is increasingly used for in vivo functional analysis. The molecules present in other teleost groups, such as the salmonids, gadoids and perciforms, are then discussed. It will become clear that some important differences exist between these fish groups and this may influence how their response to a particular pathogen is regulated.
