Fibrosis is a condition characterized by the formation of excess fibrous connective tissue in an organ or tissue as a response to injury or chronic inflammation. This excessive scarring and thickening of tissue can impair the normal function of the affected organ. Fibrosis can occur in various organs and tissues, such as the lungs, liver, kidneys, and skin, and is associated with several chronic diseases, including pulmonary fibrosis, cirrhosis, and systemic sclerosis. Research in fibrosis focuses on understanding the underlying mechanisms of fibrosis development, identifying potential therapeutic targets, and developing effective treatments to prevent or reverse fibrotic processes.
