Soft tissue Soft tissue In anatomy, soft tissue includes the tissues that connect, support, or surround other structures and organs of the body, not being hard tissue such as bone. Soft tissue includes tendons, ligaments, fascia, skin, fibrous tissues, fat, and synovial membranes (which are connective tissue), and muscles, nerves and blood vessels (which are not connective tissue). It is sometimes defined by what it is not. Soft tissue has been defined as "nonepithelial, extraskeletal mesenchyme exclusive of the reticuloendothelial system and glia". The characteristic substances inside the extracellular matrix of this kind of tissue are the collagen, elastin and ground substance.
Prolidase deficiency available for the cell to reuse – not least in the synthesis of new collagen. This recycling by prolidase, seen in the image above, is essential for maintaining proline-based systems in the cell, such as the collagen-rich extracellular matrix (ECM), which serves to physically support the structure of internal organs and connective tissues. Inadequate recycling due to a dysfunctional prolidase enzyme, caused by an appropriate mutation in the pertinent gene, leads to the deterioration of that support structure and therefore the connective tissue of the skin, capillaries, and the lymphatic tissue, as is the case in PD. In particular, it
