Led by Dr. Mariana Kaplan, the branch studies autoimmune diseases, like lupus and rheumatoid arthritis, seeking treatments and improved outcomes.
Sarthak Gupta, M.D., conducts research to better understand sex differences in neutrophil biology. He is also an investigator on several ongoing clinical trials in systemic lupus erythematosus at the NIH.
This public-private partnership seeks to develop new ways of identifying and validating promising biological targets for diagnostics and drug development.
What is reactive arthritis? Reactive arthritis happens when an infection causes joint pain and swelling. A bacterial infection in the digestive or urinary tract or the genitals usually triggers the condition, but arthritis symptoms typically do not start until a few weeks after you have recovered from the infection. The most common features of reactive arthritis are inflammation of the joints (especially the knees and ankles), eyes, and urinary tract, but not everyone gets all three, or they might not happen at the same time.
What is Sjögren’s syndrome? Sjögren’s syndrome is a chronic (long-lasting) disorder that happens when the immune system attacks the glands that make moisture in the eyes, mouth, and other parts of the body. The main symptoms are dry eyes and mouth, but the disorder may affect other parts of the body. Many people with Sjogren’s syndrome say they feel tired often (fatigue). They also may have joint and muscle pain. In addition, the disease can damage the lungs, kidneys, and nervous system.
What is systemic lupus erythematosus (lupus)? Systemic lupus erythematosus (lupus) is a chronic (long-lasting) autoimmune disease that can affect many parts of the body, including the: Skin. Joints. Heart. Lungs. Kidneys. Brain. Lupus happens when the immune system, which normally helps protect the body from infection and disease, attacks its own tissues. This attack causes inflammation and, in some cases, permanent tissue damage. If you have lupus, you may have times of illness (flares) and times of wellness (remission). Lupus flares can be mild to serious, and they do not follow a pattern. However, with treatment, many people with lupus
What is alopecia areata? Alopecia areata is a disease that causes hair loss. In alopecia areata, the immune system attacks the structures in skin that form hair (hair follicles). Alopecia areata usually affects the head and face, though hair can be lost from any part of the body. Hair typically falls out in small, round patches about the size of a quarter. In some cases, hair loss is more extensive.
What is fibromyalgia? Fibromyalgia is a long-lasting disorder that causes pain and tenderness throughout the body. It also can cause you to feel overly tired (fatigue) and have trouble sleeping. Doctors do not fully understand what causes fibromyalgia, but people with the disorder are more sensitive to pain.
What are growth plate injuries? The growth plate is the area of tissue near the ends of long bones in children and teens that determines what length and shape the bone will be once it is done growing. Each long bone— the thigh bone, the bones in the forearm, and the bones in the hands and fingers—has at least two growth plates, one at each end. Once your child has finished growing, the growth plates close and are replaced by solid bone. The growth plates are weak areas of your child’s growing skeleton, making it easier to injure them. Injuries
What is gout? Gout is a type of arthritis that causes pain and swelling in your joints, usually as flares that last for a week or two, and then go away. Gout flares often begin in your big toe or a lower limb. Gout happens when high levels of a substance called serum urate build up in your body. When this happens, needle-shaped crystals form in and around the joint. This leads to inflammation and arthritis of the joint. However, many people with high levels of serum urate will not develop gout. With early diagnosis, treatment, and lifestyle changes, gout
Research supported by the Accelerating Medicines Partnership (AMP) on Rheumatoid Arthritis and Systemic Lupus Erythematosus (RA/SLE) provides new insights into tissue damage for these autoimmune conditions. Findings include the identification of novel molecular signatures related to immune system signaling in kidney cells that may reflect their active role in disease process; molecular targets, including specific white blood cells, for potential treatment in lupus nephritis; and specific types of fibroblasts and white blood cells that are involved in rheumatoid arthritis.
Scientists can distinguish between highly similar cell types using cutting-edge laboratory procedures. Using such techniques, IRP researchers have identified a particular variety of cell in a specific stage of its life cycle as a primary culprit behind the autoimmune disease known as lupus.
Known as the “disease with a thousand faces,” systemic lupus erythematosus is a lifelong autoimmune disease with a wide range of symptoms and signs—fatigue, fever, joint pain, facial rash and skin lesions, shortness of breath, and more. It may develop suddenly or slowly and be mild or severe, with people affected going through periods of flare up and remission of their symptoms.
Researchers have identified a potential treatment to reduce the risk of cardiovascular disease in people with systemic lupus erythematosus (SLE), a chronic autoimmune disease.
What are polymyalgia rheumatica and giant cell arteritis? Polymyalgia rheumatica and giant cell arteritis are closely linked inflammatory disorders. Some people have one of the disorders while others develop both of them. Polymyalgia rheumatica causes muscle pain and stiffness in the shoulders, upper arms, hip area, and sometimes the neck. Giant cell arteritis causes inflammation of arteries, especially those on each side of the head, scalp, and the aorta (the large artery that carries blood from the heart) and its main branches. The main symptoms of this disorder are: Headaches. Scalp tenderness. Jaw pain. Problems with your eyes, which may

Sometimes, your immune system makes mistakes. If it sees your body’s healthy cells as a threat, it may attack them. This can cause an autoimmune disorder.
The FDA approved Olumiant (baricitinib) oral tablets to treat adult patients with severe alopecia areata. The action marks the first FDA approval of a systemic treatment (i.e. treats the entire body rather than a specific location) for alopecia areata.
Dr. Kaplan’s research focuses on identifying the molecular mechanisms that promote the initiation and perpetuation of perturbed immune responses and the development of organ damage and premature vascular disease in systemic autoimmunity.
