Abstract[English]
Provided herein are a class of helper lipids or pharmaceutically acceptable salts thereof. The helper lipids provided herein can be useful for delivery and expression of mRNA and encoded protein, e.g., as a component of a 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.[French]
