Abstract:
A total of 71 virulence and immunomodulation-related transcripts (VIRs) of Fasciola hepatica have been previously proposed (Haçarız et al., 2015). In an attempt to further refine this cohort, an in silico meta analysis approach was carried out using publicly available sequence data of related liver flukes, Clonorchis sinensis and Opisthorchis viverrini. Data of both liver flukes were investigated in terms of sequential homology with data of non-parasitic organisms, pathogens and VIRs of F. hepatica, directional selection (Ka/Ks), and cytokine signaling relation (protein motif based). Some VIRs of F. hepatica [showing homology with immune receptors (for toll/interleukin-1, TGF-β or TNF-α), TGF-β, TNF-α, CD147, or relation with suppressors of cytokine signaling/IKBKE 1 or stimulation of TGF-β (through thrombospondin similarity)] were found to be orthologous with those of both C. sinensis and O. viverrini. The in silico analysis indicates that on the basis of genetic commonality, a total of 30 VIRs of F. hepatica are highlighted as of foremost importance in the parasite evasion strategy, through controlling of host immune system. Findings in this study could be important to further enhance our understanding of the parasitic mechanisms and develop effective control strategies against F. hepatica and other related parasites.

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
