The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway plays a significant role in health and disease. In this pathway, cGAS, one of the major cytosolic DNA sensors in mammalian cells, regulates innate immunity and the STING-dependent production of pro-inflammatory cytokines, including type-I interferon. Moreover, the cGAS–STING pathway is integral to other cellular processes, such as cell death, cell senescence, and autophagy. Activation of the cGAS–STING pathway by “self” DNA is also attributed to various infectious diseases and autoimmune or inflammatory conditions. In addition, the cGAS–STING pathway activation functions as a link between innate and adaptive immunity, leading to the inhibition or facilitation of tumorigenesis; therefore, research targeting this pathway can provide novel clues for clinical applications to treat infectious, inflammatory, and autoimmune diseases and even cancer. In this review, we focus on the cGAS–STING pathway and its corresponding cellular and molecular mechanisms in health and disease.
