Immunomodulating transgenic plants and related methods

Abstract

The transgenic plants expressing one or more antagonist IL-10R peptides and anti-IL-10 single domain antibodies that stimulate or modulate the immune system and improve gastrointestinal physiology of an animal fed the transgenic plants or tissues thereof and the genes encoding the antagonist IL-10R peptides and anti-IL-10 single domain antibodies are described. The animal feed additives and animal feed incorporating the transgenic plants or tissues thereof are also described. Methods of stimulating or modulating an animal's immune system, improving an animal's gastrointestinal physiology, improving animal performance by using the transgenic plants or tissues thereof, and treating animals infected with a gastrointestinal pathogen are provided.
