¿Qué es el fenómeno de Raynaud? El fenómeno de Raynaud es un trastorno que hace que los vasos sanguíneos de las manos y los pies se vuelvan más angostos, disminuyendo así el flujo sanguíneo. Cuando esto sucede, partes del cuerpo, usualmente los dedos de las manos y los pies, se enfrían y se adormecen, y cambian de color (por lo general, se ponen blancos o azules). A menudo, un ataque o episodio de estos ocurre por exposición al frío o por estrés.
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. Carmelo Carmona-Rivera studies the role of post-translational modifications such as citrullination, carbamylation, and others in the pathogenesis of rheumatoid arthritis, hidradenitis suppurativa, and other autoinflammatory/autoimmune conditions.
What is Raynaud’s phenomenon? Raynaud’s phenomenon is a condition that causes the blood vessels in the hands and feet to narrow, decreasing blood flow. When this happens, parts of the body—usually the fingers and toes—become cold and numb, and change color (usually, to white or blue). An attack usually happens from exposure to cold or stress.
What is spinal stenosis? Spinal stenosis happens when the spaces in the spine narrow and create pressure on the spinal cord and nerve roots. The spinal cord is a bundle of nerves that comes out of the base of the brain and runs down the center of the spine. The nerve roots branch out from the cord. In spinal stenosis, the narrowing usually occurs over time.
What are autoimmune diseases? Autoimmune diseases refer to problems with the immune system, which usually fights off viruses, bacteria, and infection. The problem causes your immune cells to attack your body by mistake. These diseases can affect almost any part of the body.
NIH scientists developed and recently released a free, online data query tool called NeutGX. Researchers around the world can use NeutGX to explore the genetic basis of neutrophil-mediated inflammation in autoimmune diseases, cancer, infectious diseases and other conditions.
Adeline Chin, a postbaccalaureate research fellow, is searching for proteins present at abnormally high or low levels in the blood of kids with a rare autoimmune illness.
