Both TIP-DCs and Slan+ DCs have been identified in psoriatic skin, while Slan+ cells have also been identified in lupus erythematosus (141), steady state skin (143), and tonsil (144) and been shown to produce a range of cytokines upon stimulation including IL-6, IL-23, TNF-α, IL-12, and IL-1β (53, 141, 142, 144). Here, SECISBP2L is linked to lupus erythematosus.
