The complexities of cell death mechanisms: a new perspective in systemic sclerosis therapy

Abstract

Systemic sclerosis, also termed scleroderma, is a severe and debilitating autoimmune disease characterized by fibrosis, an aberrant immune response, and vascular dysfunction. Cell death is essential to the body’s continued normal development as it removes old or damaged cells. This process is governed by several mechanisms, including programmed cell death through apoptosis, necrosis, and pyroptosis, as well as metabolic processes, such as ferroptosis and cuproptosis. This review describes the signaling pathways associated with each form of cell death, examining the linkages between these pathways, and discussing how the dysregulation of cell death processes is involved in the development of autoimmune disorders such as systemic sclerosis. Existing and promising therapeutic strategies aimed at restoring the balance of cell death in systemic sclerosis and other autoimmune disorders are also emphasized.
