There is an association between rheumatoid factor and more persistently active synovitis, more joint damage, greater eventual disability and arthritis. [12] [13] Other than in rheumatoid arthritis, rheumatoid factor may also be elevated in other conditions, including: Systemic lupus erythematosus (SLE) [14] [15] Sjögren syndrome [14] [15]
1. This is the Rh-positive blood cell. 2. This is the Rh-negative blood cell. 3. These are the antigens on the Rh-positive blood cell that make it positive. The antigens allow the positive blood cell to attach to specific antibodies. Rh phenotypes are readily identified through the presence or absence of the Rh surface antigens.
It acts as a negative regulator of T-cell activation. Mutation in this gene is a risk factor for many autoimmune diseases. Weaker T-cell signaling may lead to impaired thymic deletion of autoreactive T cells, and increased PTPN22 function may result in inhibition of regulatory T cells, which protect against autoimmunity.

Blood transfusions if the disease is blood related; Physical therapy if the disease impacts bones, joints, or muscles; Traditional treatment options include immunosuppressant drugs to reduce the immune response against the body's own tissues, such as: [68] Non-steroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation
Neutrophils migrate from blood vessels to the infected tissue via chemotaxis, where they remove pathogens through phagocytosis and degranulation Inflammation is a process by which the body's white blood cells and substances they produce protect us from infection with foreign organisms, such as bacteria and viruses. The (phagocytes) white blood ...
A mast cell (also known as a mastocyte or a labrocyte [1]) is a resident cell of connective tissue that contains many granules rich in histamine and heparin.Specifically, it is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems.
A photomicrograph of the blood showing thrombocytopenia: Specialty: Hematology: Causes: Bone marrow not making enough platelets, body destroying platelets, spleen holding too many platelets [1] Diagnostic method: Complete blood count [1] Treatment: None, immunosuppressants, platelet transfusion, surgical removal of the spleen [1]
Intrinsic factor (IF), cobalamin binding intrinsic factor, [5] also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells (in humans) or chief cells (in rodents) of the stomach. It is necessary for the absorption of vitamin B 12 later on in the distal ileum of the small intestine. [6]
