Background: Most drugs that treat mood disorders take a long time to work. Ketamine works within hours. A dose can last for a week or more. Certain receptors in the brain might help ketamine work. A drug that blocks these receptors might affect how it works. Objective: To see if the antidepressant response of ketamine is linked to AMPA receptors. Eligibility: Adults ages 18-70 with major depression disorder without psychotic features Design: Participants will be screened under protocol 01-M-0254. They will have blood tests and a physical exam. Participants will stay at the NIH Clinical Center for 5 weeks. Phase 1 lasts 4 weeks. For 2 weeks, participants will taper off their psychiatric medicine. Then they will have the following tests: - Blood draws - Psychological tests - MRI: Participants will lie in a machine that takes pictures of their brain. - MEG: Participants will lie down and do tasks. A cone lowered on their head will record brain activity. - Optional sleep tests: Electrodes on the scalp and body and belts around the body will monitor participants while they sleep. - Optional TMS: Participants will do tasks while a wire coil is held on their scalp. An electrical current will pass through the coil that affects brain activity. For phase 2, on day 0 participants will take the study drug or a placebo orally. While having a MEG, they will get ketamine infused into a vein in one arm while blood is drawn from a vein in the other arm. On day 1, participants will again take the study drug or a placebo orally. On days 3-7, they will repeat many of the phase 1 tests. Days 8 and 9 are optional and include an open label ketamine treatment and many of the phase 1 tests.

The goal of this study is to learn about how the hormone insulin controls blood sugar in a variety of people. The main question it aims to answer is about how much insulin the body actually needs to maintain a normal blood sugar level. Participants will be asked to come in for a one-day study visit in which they will undergo a "graded insulin suppression test" ("GIST"). The GIST involves intravenous (into the vein) infusions of octreotide, a medication that turns off the body's own production of insulin, as well as replacement of insulin at two different levels (low and high), with or without replacement of glucagon, and glucose (sugar). The study investigators will check blood sugar levels every few minutes during the procedure to determine the effect of the two different insulin levels. This study will evaluate the GIST in both healthy volunteers and those at higher risk for type 2 diabetes.

This study is researching a drug called dupilumab. The study is focused on patients who have uncontrolled asthma. Asthma is a condition where the airways narrow and swell, making it difficult to breathe. Uncontrolled asthma means that patients are still having frequent symptoms while taking their current asthma medication. The aim of the study is to see which regimen is more effective: taking dupilumab with an inhaled asthma medication or only taking a higher dose of the inhaled asthma medication. The type of asthma medication that will be used is a combination inhaled corticosteroid and long-acting beta-agonist (referred to as an ICS/LABA). Some patients may also receive an additional asthma medication called a long-acting muscarinic antagonist (referred to as a LAMA) if they are already receiving a LAMA. The study is also looking at: • What side effects may happen from taking dupilumab

Background: Vaccines help the body learn to fight infections. Some vaccines are combined with adjuvants, which are added substances that make vaccines work better. FluMos-v2 is an experimental flu vaccine; ALFQ is an experimental adjuvant. Objective: To test FluMos-v2, with and without the ALFQ adjuvant, in healthy adults. Eligibility: Healthy adults aged 18 to 50 years. They must have received at least one flu vaccine from the 2020-21 season through the 2024-25 flu season. They must also agree not to receive the licensed 2025-26 flu vaccine. Design: Participants will have 12 clinic visits over 15 months. Participants will be screened. They will have a physical exam and blood tests. On 2 visits, about 4 months apart, participants will receive a vaccination. The shots will be given into the muscle of the upper arm. They will get a follow-up call the day after each shot. They will keep a daily diary for 7 days; they will record their temperature and any other symptoms they feel after each shot. All clinic visits will include collection of blood, saliva, and nasal secretions. If participants develop flu symptoms (such as fever, runny nose, sore throat), they will be asked to come to the clinic. About 2 weeks after each vaccination, participants may opt to undergo apheresis: Blood will be taken from the body through a needle inserted into one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be returned to the body through a needle in the other arm.

Background: Influenza (flu) is a contagious respiratory illness caused by viruses. Flu symptoms can range from mild to severe, and the illness can be fatal. Vaccines help the body learn to prevent or fight infections such as flu. Some vaccines are combined with adjuvants. Adjuvants are special salts or fats that help vaccines work better. Researchers are looking for ways to make flu vaccines more effective. Objective: To test a new flu vaccine with and without a new adjuvant. Eligibility: Healthy adults aged 18 to 50. They must have had at least 1 flu vaccine since 2020. Design: Participants will have 12 clinic visits over 15 months. The vaccine is given as an injection into the muscle of the upper arm. Participants will be vaccinated during 2 visits spaced 4 months apart. Half will receive just the vaccine; half will receive the vaccine plus the adjuvant. They will be monitored for at least 30 minutes after each shot. Participants will keep a diary for 7 days after each shot. They check their temperature every day and record any symptoms. Participants will have 10 follow-up clinic visits plus 4 phone calls. They will have 4 to 10 tablespoons of blood drawn at each clinic visit. Fluid samples will be collected from their nose and mouth. They will be checked for any health changes. Participants may opt to undergo apheresis: Blood will be taken from the body through a needle inserted into a vein. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be returned to the body through a different needle.

Background: - The Vaccine Research Center (VRC) is dedicated to understanding immune responses associated with prevention and treatment of infectious diseases. To study these immune responses, researchers need to collect specimens and images from individuals who have recently had a vaccination or recovered from an infection. These specimens and images are used to study different diseases and immune responses, and can be used to investigate ways to prevent or treat different medical conditions. Objectives: - To evaluate blood and other tissue samples for immune responses to vaccines and natural infections. Eligibility: - Healthy volunteers at least 18 years of age who agree to donate specimens for research purposes. Design: - Participants will have clinical evaluations and will be asked to provide some of the following samples, depending on the research question being addressed. All procedures and sample donations are optional and voluntary: - Blood samples through regular blood draws (for whole blood) and apheresis (to collect specific parts of the blood such as plasma or white blood cells) - Urine, semen, saliva, or vaginal swab samples - Tissue samples or biopsy specimens - Undergo procedures such as bronchoscopy (lung and respiratory tract), gastrointestinal endoscopy (stomach and upper intestinal tract), or colonoscopy (lower intestinal tract) to obtain tissue samples - Undergo imaging studies such as positron emission tomography (PET) or computed tomography (CT) scans Duration of participation is variable depending on the research question but will usually last up to 1 year. - Participants will be compensated for participation.

The purpose of this protocol is to allow for the careful screening of patients and healthy volunteers for participation in research protocols in the Experimental Therapeutics and Pathophysiology Lab (ETPB) at the National Institute of Mental Health (NIMH) and for the collection of natural history data. In addition the protocol will allow clinicians to gain more experience in the use of a variety of polysomnographic and high-density EEG recordings. Subjects in this protocol will undergo an evaluation which may include: a psychiatric interview; a diagnostic interview; rating scales; a medical history; a physical exam; brain magnetic resonance imaging (MRI); electroencephalography (EEG); electrocardiography (EKG), magnetoencephalography (MEG); blood, saliva and urine laboratory evaluation; and a request for medical records. Subjects may also be asked to complete questionnaires about attitudes towards research and motivation for research participation. The data collected may also be linked with data from other mood and anxiety disorder protocols (e.g., brain imaging, DNA, psychophysiology tests, treatment studies, etc) for the purposes of better understanding the diagnosis, pathophysiology, and treatment response of patients with mood disorders. Parents of minors will be interviewed. Upon conclusion of the screening process, subjects will either be offered participation in a research protocol and will sign the appropriate informed consent, or will be considered not appropriate for participation in research and will be referred back into the community. The current protocol thus serves as an entry point for individuals with mood or anxiety disorders or healthy volunteers to enter NIMH IRB approved ETPB protocols.

This study aims to examine the effects of a game-like program called cognitive control training (CT) for children with obsessive compulsive disorder (OCD). Children enrolled in this study will receive 4 weeks of the at-home computerized cognitive training program (AKL-T01) delivered on iPad (25 minutes/day, 5 days/week). Styled as a child-friendly video game, AKL-T01 CT taps focused attention, response inhibition, and working memory using a series of games to engage cognitive control processes. Children will complete the NIH Toolbox prior to, mid (2-weeks), and post-CT (4-weeks). Participants will complete MRI scans pre- and post-CT and then be offered a 12-week course of gold-standard Cognitive behavioral therapy with exposure and response prevention (or community referrals) after CT. The long-term goal of this study is to test how this CT intervention may enhance cognitive control capacity to reduce symptoms and improve response to cognitive behavioral therapy with exposure and response prevention in children with OCD.
