Testing a New Gold Nanoparticle-Based Lithium Delivery Method for Bipolar Disorder in Laboratory Models (GLAD)
GSK-3 as a Target for Lithium-charged Au Nanoparticles in Bipolar Disorder
This preclinical translational study aims to evaluate a new method of delivering lithium using gold nanoparticles for the treatment of bipolar disorder. Lithium is an effective treatment for bipolar disorder, but its clinical use is limited by a narrow therapeutic range and the risk of side effects. The study will investigate whether gold nanoparticles carrying lithium can improve lithium delivery to brain cells while reducing exposure to other tissues.
The research will use human induced pluripotent stem cell (iPSC)-derived neural cells generated from blood samples collected from people with bipolar disorder and healthy volunteers, as well as a mouse model of mania. No participants will receive the investigational treatment. Human participants will provide blood samples only for the generation of laboratory cell models.
The study will compare the effects of nanoparticle-delivered lithium with conventional lithium salts on cellular lithium uptake, disease-related molecular and functional changes, and biomarkers associated with bipolar disorder. The hypothesis is that lithium delivered by gold nanoparticles will achieve greater therapeutic effects at lower systemic lithium exposure than conventional lithium formulations, providing proof of concept for a safer and more targeted lithium delivery strategy for future clinical development.

Kokeellinen: Biological sample collection for iPSC/hiNSC generation
Includes both patients with Bipolar I or II Disorder (per DSM-5 criteria) and Human Healthy Controls (HC), recruited at the UOC of Clinical and Emergency Psychiatry, Fondazione Policlinico Universitario A. Gemelli IRCCS.
All participants undergo the same peripheral blood sampling procedure, with no drug or device administered.
The distinction between BD patients and healthy controls is defined by eligibility/diagnostic criteria, not by assignment or randomization to distinct arms
|
Blood collection in EDTA tubes for isolation of peripheral blood mononuclear cells (PBMCs), followed by reprogramming into induced pluripotent stem cells (iPSCs) via Sendai virus infection and differentiation into human induced neural stem cells (hiNSCs), used for the in vitro experiments of the protocol.
No drug or device is administered to participants.
