Abstract
Host defense peptides (HDPs) are important effector molecules of the innate immune system of vertebrates.
These antimicrobial peptides are also present in invertebrates, plants and fungi. HDPs display
broad-spectrum antimicrobial activities and fulfill an important role in the first line of defense of many
organisms. It is becoming increasingly clear that in the animal kingdom the functions of HDPs are not
confined to direct antimicrobial actions. Research in mammals has indicated that HDPs have many
immunomodulatory functions and are also involved in other physiological processes ranging from development
to wound healing. During the past five years our knowledge about avian HDPs has increased considerably.
This review addresses our current knowledge on the evolution, regulation and biological
functions of HDPs of birds.
