Abstract

Over the years, RNA interference (RNAi) has evolved as a valuable tool to study the tick gene function, screening and preliminary characterization of tick-protective antigens in a relatively short time, with a minimal use of laboratory animals before conducting expensive vaccine trials for the development of improved vaccine composition. In this process, a double-stranded RNA (dsRNA) of gene of interest is introduced into the tick system which specifically suppresses expression of a target gene. The results of RNAi-based gene silencing were interpreted by reduction in targeted gene transcript, changes in phenotypic data and anatomical/ biochemical changes in ticks; thereby, providing a clue to the probable role played by the gene in the tick biological system. Across the globe, various tick research groups applied RNAi technique for characterization and identification of new anti-tick vaccine targets. Herein, we used the RNAi tool in Hyalomma anatolicum ticks for identification and characterization of vaccine candidates. CI - (c) 2022.
