  Novel Series of Non-Glycerol-Based Cationic Transfection Lipids for Use in Liposomal Gene Delivery

  摘要：

  A novel series of nontoxic and non-glycerol-based simple monocationic transfection lipids containing one or two hydroxyethyl groups directly linked to the positively charged nitrogen atom were synthesized. The in vitro transfection efficiencies of these new liposomal gene delivery reagents were better than that of lipofectamine, a widely used transfection agent in cationic lipid-mediated gene transfer. The most efficient transfection formulation was observed to be a 1:1:0.3 mol ratio of DHDEAB (N,N-di-n-hexadecyl-N,N-dihydroxyethylammonium bromide): cholesterol:HDEAB (N-n-hexadecyl-N,N-dihydroxyethylammonium bromide) using a DHDEAB-to-DNA charge ratio (+/-) of 0.3:1. Observation of good transfection at charge ratios lower than 1 suggests that the amphiphile-DNA complex may have net negative charge. Our results reemphasize the important point that in cationic lipid-mediated gene delivery, the overall charge of the lipid-DNA complex need not always be positive. In addition, our transfection results also imply that favorable hydrogen-bonding interactions between the lipid headgroups and the cell surface of biological membranes may have some role for improving the transfection efficiency in cationic lipid-mediated gene delivery.

  The disclosure features isolated polynucleotides, such as mRNAs, encoding a polypeptide that disrupts immune cell activity, such as T cell or B cell activity, including mRNAs comprising one or more modified nucleobase. The immune cell disruptor polynucleotides encode a polypeptide that comprises a first domain that mediates association of the polypeptide with an immune cell component and a second domain that mediates inhibition of immune cell activity when the polypeptide is expressed in the immune cell. The disclosure also features methods of using the same, for example, for inhibiting immune responses when administered to a subject, such as to inhibit autoimmune reactions.
