Studies have reported that IMQ-induced psoriasis-like skin elicited either protein or mRNA expression of IL-17, IL- 23, IL-1β, IL-6, TNF-α, and interferon-γ(INF-γ) in mouse skin [3,35,36,37] and successful anti-psoriasis treatment inhibited the above-mentioned cytokine expression [35,36,37]. Here, TNF is linked to psoriasis.
