A nanobowl-supported drug-loaded liposome, a preparation method therefor, and an application thereof. The preparation method for the nanobowl-supported drug-loaded liposome comprises: incubating and ultrasonically treating a nanobowl and a liposome and then successfully encapsulating a drug by utilizing an ammonium sulfate active drug loading method to obtain the nanobowl-supported drug-loaded liposome. The nanobowl-supported drug-loaded liposome can resist the influence of plasma proteins and blood flow shearing forces on drug leakage, enhance the delivery of the drug at a tumor site, improve carrier stability, and improve an anti-tumor curative effect.

The present invention provides, among other things, effective methods and compositions for delivering messenger RNA (mRNA) via rectal delivery. The present invention is, in part, based on unexpected observation that mRNA may be effectively delivered to the circulation, liver, kidney, colon and/or rectum via rectal delivery despite the barriers such as RNase and mucus layer.

The present invention features methods and compositions for preventing, inhibiting, or reducing the sensation of itch (pruritus) by modulating the gene expression of TMEM184B. Modulating the gene expression of TMEM184B may comprise increasing Tmem184B protein expression, increasing Tmem184B protein activity or both. Furthermore, the methods and compositions described herein may activate the Tmem184B protein or activate a pathway leading to Tmem184B activation. Additionally, the methods and compositions for modulating the gene expression of TMEM184B may be used to help prevent or treat certain diseases or conditions such as dermatitis.
