• Age 18-75 years of age
• Ability to tolerate a simulated MRI brain scanning session

• High-affinity TSPO-binding genotype. Mixed (high/low) binding-affinity genotype may be included at PIs discretion
• For participants with severe asthma:
• Physician diagnosis of asthma for at least six months prior to screening (can be determined at the discretion of an asthma/allergy physician member of the study team)
• Severe asthmatics must meet the ATS definition of severe asthma and/or be currently receiving a GINA 5 therapy (or greater), which may include ongoing use of currently approved biologic immunomodulators
• Current smoker (defined as more than 0.5 pack per week for the past 6 months and any smoking within two weeks of study procedures) or has a smoking history exceeding 5 pack years within the last 10 years
• Currently receiving immunotherapy
• Use of psychotropic medication that might affect function of neurocircuitry implicated in our hypotheses (at the discretion of the PI/Co-I)
• Inability to hold medications detailed in the medication hold schedule
