Myxedema describes a specific form of cutaneous and dermal edema secondary to increased deposition of connective tissue components. The connective fibres are separated by an increased amount of protein and mucopolysaccharides. These can include glycosaminoglycans, such as hyaluronic acid, chondroitin sulfate and other mucopolysaccharides. [2]
Arthritis is a common acute or chronic condition affecting the joints and surrounding tissues. It’s estimated that roughly 18 percent of American adults have some form of arthritis. And about 44 ...
Connective tissue is one of the four primary types of animal tissue, a group of cells that are similar in structure, along with epithelial tissue, muscle tissue, and nervous tissue. [1] It develops mostly from the mesenchyme , derived from the mesoderm , the middle embryonic germ layer . [ 2 ]
Some disorders, such as systemic lupus erythematosus (SLE) may be more likely if several autoantibodies are present, while others, such as mixed connective tissue disease (MCTD) may be more likely if a single autoantibody, ribonucleic protein (RNP), is the only one present. Those who have more than one autoimmune disorder may have several ...
The diagnosis of autoimmune connective tissue diseases (CTDs) is done through analysis of clinical symptoms and signs, but also through the identification of the autoantibodies directed against nuclear antigens. A 2002 paper also seeks to compare the diagnostic tests used in immunology laboratories to measure anti-ENAs and ways to improve this ...
Within adults and developing adults, most chondroblasts are located in the perichondrium. This is a thin layer of connective tissue which protects cartilage and is where chondroblasts help to expand cartilage size whenever prompted to by hormones such as GH , TH , and glycosaminoglycans . [ 2 ]

Mast cells were once thought to be basophils that migrated from the blood into their resident tissues (connective tissue), but they are now known to be different types of cells. [ 5 ] Basophils were discovered in 1879 by German physician Paul Ehrlich , who one year earlier had found a cell type present in tissues that he termed mastzellen (now ...
