negatively regulates negatively regulates programmed cell death negative regulation of programmed cell death modulation by symbiont of host process modulation by symbiont of host programmed cell death negative regulation by symbiont of host programmed cell death down-regulation by symbiont of host programmed cell death Any process in which an organism stops, prevents, or reduces the frequency, rate or extent of programmed cell death in the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction. suppression by symbiont of host PCD downregulation by symbiont of host programmed cell death inhibition of host programmed cell death suppression by symbiont of host programmed cell death down regulation by symbiont of host programmed cell death inhibition by symbiont of host programmed cell death biological_process GO:0052041
