The Laboratory of Oral Connective Tissue Biology studies the molecular biology of dental-oral-craniofacial development, with a focus on the teeth, gums, and related jaw structure. The aim of these studies is to understand cells and signals influencing tooth, bone, and periodontal ligament development in order to identify improved regenerative ...
Connective tissue diseases can be classified into two groups: (1) a group of relatively rare genetic disorders affecting the primary structure of connective tissue; and (2) a number of acquired conditions where the connective tissues are the site of multiple, more or less distinct immune and inflammatory reactions.
Palisaded neutrophilic and granulomatous dermatitis (PNGS) is usually associated with a well-defined connective tissue disease, lupus erythematosus or rheumatoid arthritis most commonly, and often presents with eroded or ulcerated symmetrically distributed umbilicated papules or nodules on the elbows.

Dermatomyositis is a form of systemic connective tissue disorder, a class of diseases that often involves autoimmune dysfunction. [15] [23] It has also been classified as an idiopathic inflammatory myopathy, along with polymyositis, necrotizing autoimmune myositis, cancer-associated myositis, and sporadic inclusion body myositis. [24]
Rheumatism [2] / ˈ r uː m ə t ɪ z əm / or rheumatic disorders are conditions causing chronic, often intermittent pain affecting the joints or connective tissue. [3] Rheumatism does not designate any specific disorder, but covers at least 200 different conditions, including arthritis and "non-articular rheumatism", also known as "regional pain syndrome" or "soft tissue rheumatism".
There are also uncompleted versions of recognized connective tissue diseases, in which clinical and serological symptoms allow for a diagnosis but classification criteria are not met. [67] The most prevalent strategy to diagnosis in clinical practice combines serological criteria with at least three clinical criteria.
Hypermobility can also be caused by connective tissue disorders, such as Ehlers–Danlos syndrome (EDS) and Marfan syndrome. Joint hypermobility is a common symptom for both. EDS has numerous sub-types; most include hypermobility in some degree. When hypermobility is the main symptom, then EDS/hypermobility type is likely.
Collagen disease is a term previously used to describe systemic autoimmune diseases (e.g., rheumatoid arthritis, systemic lupus erythematosus, and systemic sclerosis), but now is thought to be more appropriate for diseases associated with defects in collagen, which is a component of the connective tissue. [1] The term "collagen disease" was ...
