obsolete induction by symbiont of host immune response https://github.com/geneontology/go-ontology/issues/26664 true positive regulation by organism of immune response of other organism involved in symbiotic interaction OBSOLETE. Any process in which a symbiont activates the immune response of the host organism; the immune response is any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat. The host is defined as the larger of the organisms involved in a symbiotic interaction. activation by symbiont of host immune response GO:0052555 GO:0052556 positive regulation by symbiont of host immune response GO:0052559 GO:0052558 stimulation by symbiont of host immune response induction by organism of immune response of other organism involved in symbiotic interaction biological_process up-regulation by symbiont of host immune response up regulation by symbiont of host immune response The reason for obsoletion is that this terms was not clearly defined and has been incorrectly used. upregulation by symbiont of host immune response
