Background: Inhaled corticosteroids, such as budesonide, attenuate the inflammatory response in asthma. However, patient noncompliance and side effects of available inhaled corticosteroids limit their use. Liposomes are currently used in medicine to deliver a variety of drugs.
Objective: The objective of our study was to determine whether weekly therapy with budesonide encapsulated in sterically stabilized (stealth) liposomes would be comparable to daily budesonide therapy in reducing allergic inflammation.
Methods: Ovalbumin-sensitized C57/Black 6 mice received aerosolized (1) budesonide encapsulated in stealth or conventional liposomes, administered weekly, (2) budesonide (without liposomes), administered either daily or weekly, or (3) empty stealth liposomes, administered weekly. All treatment groups were compared with sensitized untreated or unsensitized mice. Histopathologic examination of the lung tissues and measurements of eosinophil peroxidase activity, peripheral blood eosinophil counts, and total serum IgE levels were done weekly for 4 weeks.
Results: Weekly therapy with budesonide encapsulated in stealth liposomes was as effective as daily budesonide therapy in decreasing lung inflammation and lowering eosinophil peroxidase activity, peripheral blood eosinophils, and total serum IgE levels. In none of the other groups was there a significant decrease in the inflammatory parameters evaluated.
Conclusion: We conclude that weekly therapy with budesonide encapsulated in stealth liposomes is as effective as daily budesonide in reducing markers of lung inflammation in experimental asthma. This novel strategy offers an effective alternative to standard daily budesonide therapy in asthma and has the potential to reduce toxicity and improve compliance.

As an advanced nucleic acid therapeutical modality, mRNA can express any type of protein in principle and thus holds great potential to prevent and treat various diseases. Despite the success in COVID-19 mRNA vaccines, direct local delivery of mRNA into the lung by inhalation would greatly reinforce the treatment of pulmonary pathogens and diseases. Herein, we developed lipid nanoparticles (LNPs) from degradable ionizable glycerolipids for potent pulmonary mRNA delivery via nebulization.

Inflammatory bowel disease (IBD) is a chronic and recurrent inflammatory disease that affects the gastrointestinal tract. The major hurdles impeding IBD treatment are the low targeting efficiency and short retention time of drugs in IBD sites. Nanoparticles with specific shapes have demonstrated the ability to improve mucus retention and cellular uptake.

Budesonide is a mineral corticoid applied in the local therapy of pediatric atopic dermatitis. Unfortunately, its dermal administration is hindered by the concomitant adverse effects and its physicochemical properties. The characteristic pH change in the atopic lesions can be utilized for the preparation of a pH-sensitive nanocarrier.

IgA nephropathy (IgAN) is the most frequent primary form of glomerulonephritis. The origin of IgAN is only partially understood and appears to involve the occurrence of IgA, which is normally secreted by mucous membranes, in the circulation followed by its glomerular deposition and inflammatory changes. Clinically, IgAN mostly follows an inapparent course and the disease is often only first diagnosed by kidney biopsy when kidney function disorders are already manifested.
