IFIT5 Participates in the Antiviral Mechanisms of Rainbow Trout Red Blood Cells
We described a new defense mechanism based on IFIT5 antiviral activity in nucleated RBCs that appeared to contribute to halting the VHSV infection. This finding sheds light into novel antiviral therapeutics to mitigate the economic losses and social impact caused by viral infections in the aquaculture industry. This work broadens the knowledge of fish nucleated RBCs functions and their role in the immune response to viral infections. Ethics Statement Experimental protocols and methods relating to experimental animals were reviewed and approved by the Animal Welfare Body and the Research Ethics Committee at the University...

Evaluation of siRNA and Cationic Liposomes Complexes as a Model for in vitro siRNA Delivery to Cancer Cells
This study aims to investigate the effect of different molar charge ratios (R+/-) between positive charges from microfluidics-produced cationic liposomes (CL) (egg phosphatidylcholine, 1,2-dioleoyl-3-trimethylammonium-propane and 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine) and negative charges from siRNA and on physico-chemical and morphological properties of the lipoplexes (CL/siRNA) as well as their in vitro luciferase silencing effect in HeLa cells. R+/- 3.27 was found to be the optimum point for complexation. This finding was confirmed by gel retardation and siRNA accessibility assays. According to Cryo-TEM analysis...
