Immunological mechanisms of scarring and their psychological impact on patients

摘要

A scar is a local symptom, which results from severe physical, biological and chemical damage to human skin and soft tissue. Scars can affect both skin appearance and function. The affected skin or soft tissue cannot be completely repaired normally by itself and is replaced by formed fibrous tissue. Patients with scars can develop physical pain and mental conditions, especially those with scars left after burns, scalds and severe traumas. The scar proliferation phase can be up to several years which could be almost unbearable for patients. Also, the atrophic period afterwards makes the patient’s face unrecognizable and dysfunctional, causing great physical and mental impairment. Therefore, scar repair is of great clinical importance for patients, and understanding the immunological mechanisms of scar repair is an important prerequisite for the effective treatment of scars. This study is a systematic review of current research advances about the immunological mechanisms of scar repair, so as to provide a reference for the selection of regimens in clinical treatment.
