Gene silencing induced by DNA viruses leading to a sequence-specific degradation of target mRNAs or post-transcriptional gene silencing. The posttranscriptional gene silencing of viral genes after viral infection. The posttranscriptional gene silencing of host genes that are homologous to viral genes after viral infection. The set of cellular processes occurring in the host cell that contribute to the process of posttranscriptional gene inactivation ('silencing') both of viral gene(s), and host gene(s) homologous to the viral genes. The process by which an organism effects a change in the structure or processes of its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction. Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack. The alteration by an organism of the levels of RNA in a second organism, where the two organisms are in a symbiotic interaction. Gene silencing induced by RNA viruses leading to a sequence-specific degradation of target mRNAs or post-transcriptional gene silencing. A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a virus. Specific posttranscriptional gene inactivation ('silencing') both of viral gene(s), and host gene(s) homologous to the viral genes. This silencing is triggered by viral infection, and occurs through a specific decrease in the level of mRNA of both host and viral genes. Reactions triggered in response to the presence of a virus that act to protect the cell or organism. Any process of the immune system that occurs as part of an immune response. Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat. Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. The alteration by an organism of the levels of RNA in the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction. Any process that increases the frequency, rate or extent of the inactivation of gene expression of both viral genes and host homologues to those genes by a posttranscriptional mechanism in a virally infected cell.
