The present invention is in the field of immunotherapy, in particular tumor immunotherapy. The present invention provides pharmaceutical formulations for delivering RNA to antigen presenting cells such as dendrite cells (DCs) in the spleen after systemic administration. In particular, the formulations described herein enable to induce an immune response after systemic administration of antigen-coding RNA.

The present invention provides, among other things, methods and compositions for treating primary ciliary dyskinesia (PCD) based on mRNA therapy. The compositions used in treatment of PCD comprise an mRNA comprising a dynein axonemal heavy chain 5 (DNAH5) coding sequence and are administered at an effective dose and an administration interval such that at least one symptom or feature of PCD is reduced in intensity, severity, or frequency or has a delayed onset. mRNAs with optimized DNAH5 coding sequences are provided that can be administered without the need for modifying the nucleotides of the mRNA to achieve sustained in vivo function.

The present disclosure relates to tertiary amino lipidated and/or PEGylated cationic peptide compounds and complexes thereof with nucleic acids for endocellular delivery, methods for preparing the compounds and complexes, and methods for delivering polyanionic compounds to cells.

The present invention is in the field of immunotherapy, in particular tumor immunotherapy. The present invention provides pharmaceutical formulations for delivering RNA to antigen presenting cells such as dendrite cells (DCs) in the spleen after systemic administration. In particular, the formulations described herein enable to induce an immune response after systemic administration of antigen-coding RNA.

Disclosed herein are non-naturally occurring vesicle comprising a chimeric vesicle localization moiety comprising a surface-and-transmembrane domain of a first vesicle localization moiety and a cytosolic domain of a second vesicle localization moiety, the method of making said vesicle and uses thereof.

Compositions and methods for the treatment of tuberculosis, as well as other mycobacterial and gram positive bacterial infections are disclosed. These compositions contain a highly potent and selective oxazolidinone encapsulated with high efficiency to maximize dosing potential of low toxicity drugs, and are stable in the presence of plasma. The compositions are long circulating and retain their encapsulated drug while in the circulation following intravenous dosing to allow for efficient accumulation at the site of the bacterial or mycobacterial infection. The high doses that can be achieved when combined with the long circulating properties and highly stable retention of the drug allow for a reduced frequency of administration when compared to daily or twice daily administrations of other drugs typically utilized to treat these infections.

The disclosure relates to nanoparticles comprising a lipid component and a modified RNA encoding a VEGF-A polypeptide. Aspects of the disclosure further relate to uses of nanoparticles comprising a lipid component and a modified RNA encoding a VEGF-A polypeptide, for improving wound healing in a subject.

An object of the present invention is to provide a lipid composition capable of achieving excellent nucleic acid delivery. According to the present invention, there is provided a lipid composition containing a lipid represented by Formula (1) or a salt thereof, a nucleic acid, at least one non-cationic lipid, and a lipid represented by R.sup.51-L-(OCH.sub.2CH.sub.2).sub.n—O-R.sup.52 (in the formula, R.sup.51 represents a hydrocarbon group having 6 to 30 carbon atoms, L represents —CO— or a single bond, R.sup.52 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, and n represents an integer of 10 to 150).

##STR00001##

In the formula, each symbol means the definition described in the description.

Disclosed are cationic lipids which are compounds of Formula I. Cationic lipids provided herein can be useful for delivery and expression of mRNA and encoded protein, e.g., as a component of liposomal delivery vehicle, and accordingly can be useful for treating various diseases, disorders and conditions, such as those associated with deficiency of one or more proteins. ##STR00001##

The present embodiment provides a compound represented by the formula (1):
Q-CHR.sub.2  (1)
(Q is a nitrogen-containing aliphatic group containing two or more tertiary nitrogens but no oxygen, and R is an aliphatic group containing a biodegradable group). From the compound in combination with other lipids such as a lipid capable of reducing aggregation, lipid particles can be formed. Further, the compound can be used for a pharmaceutical composition to deliver an activator into cells.
