abstract = {The duck represents an important reservoir of influenza
viruses for transmission to other avian and mammalian hosts,
including humans. The increased pathogenicity of the
recently emerging clades of highly pathogenic avian
influenza (HPAI) viruses of the H5N1 subtype in ducks
features systemic viral spread and organ-to-organ variation
in viral transcription and tissue damage. We previously
reported that experimental infection of Sudani ducks
(Cairina moschata) with an Egyptian HPAI (H5N1) virus (clade
2.2.1.2) features high viral replication and severe tissue
damage in lung, but lower viral replication and only mild
histological changes in brain. Little is known about the
involvement of miRNA in organ-specific responses to H5N1
viruses in ducks, and involvement of the other classes of
small noncoding RNA (sncRNA) has not been investigated so
far. Following RNA sequencing, we have annotated the duck
sncRNome and compared global expression changes of the four
major sncRNA classes (miRNAs, piRNAs, snoRNAs, snRNAs)
between duck lung and brain during a 120 h time course of
infection with this HPAI strain. We find major
organ-specific differences in miRNA, piRNA and snoRNA
populations even before infection and substantial
reprogramming of all sncRNA classes throughout infection,
which was less pronounced in brain. Pathway prediction
analysis of miRNA targets revealed enrichment of
inflammation-, infection- and apoptosis-related pathways in
lung, but enrichment of metabolism-related pathways
(including tryptophan metabolism) in brain. Thus,
organ-specific differences in sncRNA responses may
contribute to differences in viral replication and organ
damage in ducks infected with isolates from this emerging
HPAI clade, and likely other strains.},
