Background: The vicious cycle between depression and dementia increases the risk of Alzheimer's Disease (AD) pathogenesis and pathology. This study investigates therapeutic effectiveness versus side effects and the underlying mechanisms of intranasal dantrolene nanoparticles (IDNs) to treat depression behavior and memory loss in 5XFAD mice.
Method: 5XFAD and wild-type B6SJLF1/J mice were treated with IDNs (IDN, 5 mg/kg) in Ryanodex formulation for a duration of 12 weeks.

Henan Academy of Innovations in Medical Science, Zhengzhou, Henan, China.
Background: Glucagon-like peptide 1 (GLP-1) is a peptide hormone that plays several physiological roles in treating diabetes and in protecting the brain. Recent clinical trials testing 4 different GLP-1 class drugs in phase 2 trials showed a clear correlation between neuroprotection and the ability to cross the BBB. Exenatide and Lixisenatide both showed excellent protective effects in patients Parkinson's disease (PD) and both drugs can readily cross the BBB.

Background: This study investigates the therapeutic versus side effects of intranasal lithium chloride (LiCl) in Ryanodex formulation vehicle (RFV) to inhibit inflammation and pyroptosis and to ameliorate on cognitive dysfunction and depressive behavior in 5XFAD mice.
Method: 5XFAD and wild type (WT) B6SJLF1/J mice were treated with intranasal or oral LiCl (3 mM/kg) dissolved in RFV starting at 2 or 9 months old and the continuous treatment lasted for 12 weeks. Behavior was examined for depression, cognition, olfaction, and motor function at the ages of 5 or 12 months.

Aging is associated with declines in memory function and significant change in gut microbiota. In this study, we investigated how exercise affects age-related memory decline and inflammation, and gut microbiota diversity. Bl6 mice were divided into control, control and exercise, old, and old and exercise groups.

Atopic dermatitis (AD) is a prevalent, persistent inflammatory skin disorder distinguished by pruritic and irritated skin. Toll-like receptors (TLRs) are specialized receptors that recognize specific patterns associated with pathogens and tissue damage, triggering an innate immune response that protects the host from invading pathogens. Previously, it was demonstrated that intradermal injection of the humanized anti-TLR2 monoclonal antibody (Ab) Tomaralimab effectively relieved AD-like skin inflammation in BALB/c mouse models exposed to house dust mite extracts.
