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.
Led by Dr. Mariana Kaplan, the branch studies autoimmune diseases, like lupus and rheumatoid arthritis, seeking treatments and improved outcomes.
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.
Dr. Lewandowski leads a team of scientists studying the genetics of early-onset systemic lupus erythematosus patients in populations around the globe. Her research focuses on genetic drivers of severe disease and inflammation in diverse cohorts worldwide.
What is atopic dermatitis? Atopic dermatitis, often called eczema, is a chronic (long-lasting) disease that causes the skin to become inflamed and irritated, making it extremely itchy. Scratching leads to: Redness. Swelling. Cracking. “Weeping” clear fluid. Crusting. Scaling. In most cases, there are times when the disease is worse, called flares, followed by times when the skin improves or clears up entirely, called remissions. Atopic dermatitis is a common condition, and anyone can get the disease. However, it usually begins in childhood. Atopic dermatitis cannot be spread from person to person. No one knows what causes atopic dermatitis. Depending on
What is osteonecrosis? Your bones are made up of living cells that need a blood supply to stay healthy. In osteonecrosis, blood flow to part of a bone is reduced. This causes death of bone tissue, and the bone can eventually break down and the joint will collapse. Osteonecrosis can happen to any bone, but most often it develops in the ends of long bones, such as the: Thigh bone. Upper arm bone. Less often, the bones of the elbows, ankles, feet, wrists, and hands are affected. When the disease involves part of a bone in a joint, it can
What is back pain? Back pain is one of the most common medical problems in the United States. It might feel like a dull, constant ache or a sudden, sharp pain. Back pain can result from: An accident. A fall. Lifting something heavy. Changes that happen in the spine as you age. A disorder or medical condition. Treatment depends on the cause and symptoms of your pain. You can do things to improve your health and lower your chance of developing chronic (long-lasting) back pain.
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
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.
The human back is a complex structure with bones, nerves, tendons, discs, and more — all places where something can go wrong and cause pain, which, for many people, becomes a long-term or chronic problem. Life stresses and other medical and mental health conditions aggravate the problem. With so many pieces, it’s hard to get a holistic view of the puzzle or pinpoint the cause of the pain. “People tend to focus on one aspect or another,” said Jeffrey Lotz, Ph.D., a medical engineer who studies back pain at the University of California, San Francisco. “Some people think it’s largely
Researchers have identified a potential treatment to reduce the risk of cardiovascular disease in people with systemic lupus erythematosus (SLE), a chronic autoimmune disease.
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.
A research team led by Dr. Makarand Risbud of Thomas Jefferson University tested whether treatment with the drugs dasatinib and quercetin would prevent disc degeneration in mice. Both drugs are senolytics, which selectively remove aged cells known as senescent cells.
Researchers published a proof-of-principle paper in the journal Science Immunology demonstrating just how precision medicine for inflammatory skin rashes might work.
