Therapeutic methods for using the cells and microorganisms to prevent of ameliorate diseases are also provided. The genetically engineered cells or microorganisms can be engineers to express a signal and used to interrupt the signaling-dependent virulence of an invading pathogen. The cells or microorganisms can be used to provide signaldependent expression of a desirable gene in order to interrupt, prevent, and/orameliorate a disease of mammals, such as parasitic diseases, infectious diseases, autoimmune diseases and genetic disorders.
