A change in morphology and behavior of a basophil resulting from exposure to a cytokine, chemokine, soluble factor, or to (at least in mammals) an antigen which the basophil has specifically bound via IgE bound to Fc-epsilonRI receptors, leading to the initiation or perpetuation of an immune response. (Gene Ontology, GO_0002276)
1 genes participating in the basophil activation involved in immune response biological process from the curated GO Biological Process Annotations dataset.
