The chemotactic cytokine CC subfamily includes the regulated upon activation typical T cell produced and released factor (SLENTES), which is highly expressed in SLE and is closely related to tissue and organ inflammatory damage, when T cells are stimulated late, a transcription factor called KLF13 (SLENTES factor of late-activated T lymphocytes-1, RFLAT-1) encourages the production of SLENTES [11,12]. Here, KLF13 is linked to systemic lupus erythematosus.
