Resumo: Small, non-coding, RNAs such as microRNAs (miRNA) of length 18-24 nucleotide are reported in wide range of organisms and known to play a determinative role in regulation of various cellular processes. They have also reported to have regulatory roles during pathogen infection, maturation and transmission. Chikungunya virus is an important alphavirus transmitted through two important vectors, Aedes aegypti and Ae. albopictus. While Ae. aegypti has been the preferred vector for transmission of this virus, recently, Ae. albopictus has gained notoriety for disease transmission. Using Illumina platform, we sequenced the small RNA population an Aedes albopictus cell line infected with chikungunya virus. We studied the expression modulation of miRNAs upon CHIKV infection and found distinct set of miRNAs regulated in Aedes upon CHIKV infection. We further predicted the targets of these miRNAs and performed pathway analysis of these targets. The cellular functional targets of some of these miRNAs overlapped suggesting aggressive participation of the targeted pathways in establishing CHIKV infection.
