Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?
MIR340 is a host microRNA implicated in the regulation of antiviral responses, specifically targeting the antiviral factors RIG-I and OAS2, which are crucial in the host's defense against influenza virus infection [PMC6370596]. The study's findings suggest that MIR340 may play a role in modulating immunity, as its inhibition could potentially enhance the immune response against influenza by reducing the suppression of these key antiviral proteins [PMC6370596]. The identification of MIR340 target sites within the 3สน UTR of RIG-I at positions 1,657 and 1,809 supports the strategy of targeting host miRNAs as a novel therapeutic approach to combat influenza virus infection [PMC6370596]. This approach is consistent with previous reports that miRNA-dependent strategies have been developed for viral infections and that modulating miRNA activity can have a significant impact on viral resistance, as seen with miR144-deficient mice and their resistance to influenza virus [PMC6370596].

Comments
This sequence is the predicted homologue of a miRNA cloned from rat neuronal tissue [1,2]. Landgraf et al. show that the 5' product is the predominant one in human, mouse and rat [3], in contrast to the previous annotation. The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [3].
