SLE monocytes also display a senescent program marked by increased cyclin-dependent kinase inhibitor 2A (CDKN2A), which induces GATA-binding protein 4 (GATA4) and augments IFN-α production via activation of the cGAS–STING pathway, thereby linking cellular aging to inflammation [283]. The gene discussed is GATA4; the disease is systemic lupus erythematosus.
