"Any process in which the symbiont organism activates, maintains or increases the frequency, rate or extent of its G-protein coupled receptor protein-mediated signal transduction as a result of detecting molecules of its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction." . . . . "positive regulation of G-protein coupled receptor protein signaling pathway in response to host" .
