Abstract
Targeting mRNA formulations to achieve cell specificity is one of the challenges that must be tackled to mettle their therapeutic potential. Here, lipopolyplexes (LPR) bearing tri-mannose-lipid (TM) are used to target mannose receptor on dendritic cells. We investigated the impact of the net charge and percentage of TM units on the binding, uptake, transfection efficiency (TE) and RNA sensors activation. Binding and uptake capacities of naked and targeted LPR increase with the percent of cationic lipid, but the latter are 2-fold more up taken by the cells. Cationic LPR bearing 5 % and 10 % TM were localized in acidic compartments in contrast to naked LPR and 2.5 % TM-LPR. The drawback is the dramatic decrease of TE as the number of TM-units increases. Cationic LPR bearing 5 % and 10 % TM strongly induced NF-κB and PKR phosphorylation at 6 h. Conversely, mTOR is less activated in line with their low TE. Those side effects are overcome by using 5-methoxyuridine mRNA resulting in an improved TE due to non-phosphorylation of NF-κB and PKR and mTOR activation. Our results point out that targeting DC via mannose receptor triggers a higher uptake of cationic LPRs and fast routing to acidic compartments, and that efficient TE requires low number of TM units use or modified mRNA to escape RNA sensors activation to enhance the translation.

Abstract
The use of nucleic acids as templates, which can trigger the self-assembly of their own vectors represent an emerging, simple and versatile, approach toward the self-fabrication of tailored nucleic acids delivery vectors. However, the structure-activity relationships governing this complex templated self-assembly process that accompanies the complexation of nucleic acids remains poorly understood. Herein, the class of arginine-rich dynamic covalent polymers (DCPs) composed of different monomers varying the number and position of arginines were studied. The combinations that lead to nucleic acid complexation, in saline buffer, using different templates, from short siRNA to long DNA, are described. Finally, a successful peptidic DCP featuring six-arginine repeating unit that promote the safe and effective delivery of siRNA in live cancer cells was identified.

Abstract
The perspective of using messenger RNA (mRNA) as a therapeutic molecule first faced some uncertainties due to concerns about its instability and the feasibility of large-scale production. Today, given technological advances and deeper biomolecular knowledge, these issues have started to be addressed and some strategies are being exploited to overcome the limitations. Thus, the potential of mRNA has become increasingly recognized for the development of new innovative therapeutics, envisioning its application in immunotherapy, regenerative medicine, vaccination, and gene editing. Nonetheless, to fully potentiate mRNA therapeutic application, its efficient production, stabilization and delivery into the target cells are required. In recent years, intensive research has been carried out in this field in order to bring new and effective solutions towards the stabilization and delivery of mRNA. Presently, the therapeutic potential of mRNA is undoubtedly recognized, which was greatly reinforced by the results achieved in the battle against the COVID-19 pandemic, but there are still some issues that need to be improved, which are critically discussed in this review.

Abstract
Dynamic covalent libraries enable exploring complex chemical systems from which bioactive assemblies can adaptively emerge through template effects. In this work, we studied dynamic covalent libraries made of complementary bifunctional cationic peptides, yielding a diversity of species from macrocycles to polymers. Although polymers are typically expressed only at high concentration, we found that siRNA acts as a template in the formation of dynamic covalent polymers at low concentration in a process guided by electrostatic binding. Using a glycosylated building block, we were able to show that this templated polymerization further translates into the multivalent presentation of carbohydrate ligands, which subsequently promotes cell uptake and even cell-selective siRNA delivery.
