Cutibacterium acnes phylotypes diversity loss: a trigger for skin inflammatory process.

Summary of "Cutibacterium acnes phylotypes diversity loss: a trigger for skin inflammatory process."

Acne has long been understood as a multifactorial chronic inflammatory disease of the pilosebaceous follicle, where Cutibacterium acnes (subdivided into six main phylotypes) is a crucial actor. In parallel, the loss of microbial diversity among the skin commensal communities has recently been shown as often accompanied with inflammatory skin disorders.

Medical and Biotech [MESH] Definitions

A bacteria isolated from normal skin, intestinal contents, wounds, blood, pus, and soft tissue abscesses. It is a common contaminant of clinical specimens, presumably from the skin of patients or attendants.

A subacute or chronic inflammatory disease of muscle and skin, marked by proximal muscle weakness and a characteristic skin rash. The illness occurs with approximately equal frequency in children and adults. The skin lesions usually take the form of a purplish rash (or less often an exfoliative dermatitis) involving the nose, cheeks, forehead, upper trunk, and arms. The disease is associated with a complement mediated intramuscular microangiopathy, leading to loss of capillaries, muscle ischemia, muscle-fiber necrosis, and perifascicular atrophy. The childhood form of this disease tends to evolve into a systemic vasculitis. Dermatomyositis may occur in association with malignant neoplasms. (From Adams et al., Principles of Neurology, 6th ed, pp1405-6)

The phenomenon of immense variability characteristic of ANTIBODIES. It enables the IMMUNE SYSTEM to react specifically against the essentially unlimited kinds of ANTIGENS it encounters. Antibody diversity is accounted for by three main theories: (1) the Germ Line Theory, which holds that each antibody-producing cell has genes coding for all possible antibody specificities, but expresses only the one stimulated by antigen; (2) the Somatic Mutation Theory, which holds that antibody-producing cells contain only a few genes, which produce antibody diversity by mutation; and (3) the Gene Rearrangement Theory, which holds that antibody diversity is generated by the rearrangement of IMMUNOGLOBULIN VARIABLE REGION gene segments during the differentiation of the ANTIBODY-PRODUCING CELLS.

Loss of water by diffusion through the skin and by evaporation from the respiratory tract.

Benign DERMATOSIS caused by a loss of dermal ELASTIC TISSUE resulting in localized sac-like areas of flaccid skin. It can be either primary (idiopathic) or secondary to other skin conditions, PENICILLAMINE use, or premature birth.
