Teunissen et al. in the current issue and Villanova et al. (JID, 134, 984-99) now suggest an important role for type 3 ILCs (ILC3s) in the skin, particularly in psoriasis. Psoriasis cannot be explained purely by genetics (Elder et al 2001) or environment; it has a complex immunopathology that is not fully understood.

Histology allows the analysis using light microscopy (LM), immunohistology or electron microscopy (EM).

Guttate psoriasis is associated with streptococcal throat infection 2The trends from (Bertrand-Vallery et al 2010; Teunissen et al 1993) were fitted into a sigmoid equation known as the Emax equation (MacDougall 2006). Also, clinical data support the involvement of Th17 cells in psoriasis, as early disease improvement in patients treated with the TNF- inhibitor etanercept coincides in time with the reduction of Th17 gene products and downstream effector molecules 26. Psoriasis is a disease with a genetic background (4). De Rie MA, Teunissen MB, Piskin G. Psoriasis: dysregulation of innate immunity.

Similar to clinical trials in RA, trials in psoriatic arthritis (PsA) have shown excellent clinical results with the tumour necrosis factor (TNF) blockers, etanercept, infliximab, and adalimumab in a variety of domains including the joints, quality of life, function, and slowing of disease progress as evidenced radiologically.

The majority of epidermal T cells in Psoriasis vulgaris lesions can produce type 1 cytokines, interferon-, interleukin-2, and tumor necrosis factor-, defining TC1 (cytotoxic T lymphocyte) and TH1 effector populations: a type 1 differentiation bias is also measured in circulating blood T cells in psoriatic patients.
