What this research studies

If you join, you would be a healthy volunteer who breathes a controlled xenon gas mixture for short sessions lasting 10, 20, 30, or 45 minutes. Study staff will monitor vital signs and collect blood samples to look for immune changes and any side effects. The team is especially interested in immune signals related to brain microglia and genetic risk factors like APOE because these pathways may matter for Alzheimer's disease. This Phase 1 trial focuses on short-term safety and biological effects in people without dementia.

Who could benefit from this research

Good fit: Healthy adults without cognitive impairment who pass the study's medical screening would be eligible to participate.

Not a fit: People with Alzheimer's disease or other dementias, or those with active medical issues (for example pregnancy, lung or heart problems) who fail screening would not be expected to benefit from this early safety trial.

Why it matters

Potential benefit: If safe and biologically active, xenon inhalation could point to new ways to protect brain cells and modify immune responses relevant to Alzheimer's disease.

How similar studies have performed: Xenon has been used as an anesthetic and shown neuroprotective effects in animal studies, but its immune effects in healthy humans for Alzheimer's-related targets are largely untested.
