Imiquimod (IMQ) is a toll-like receptor 7/8 (TLR7/8) agonist that induces strong psoriatic inflammation by activating innate immune pathways and stimulating the release of cytokines, including IL-23, IL-17, TNF-α, and IFN-γ. When applied to human skin explants, imiquimod disrupts epidermal homeostasis, initiating keratinocyte hyperproliferation, altered differentiation, and immune cell infiltration-like responses that closely mimic human psoriasis. The imiquimod-induced ex vivo psoriasis models provide a powerful, ethically sustainable alternative to animal testing, offering translational insights while preserving the three-dimensional architecture and barrier properties of human skin.

Ace Therapeutics provides imiquimod-induced ex vivo psoriasis model development services to support pharmaceutical companies and academic researchers in accelerating the discovery and development of anti-psoriatic drugs.
At Ace Therapeutics, we support clients in the development of imiquimod-induced ex vivo psoriasis models using full-thickness human skin explants. Our experts culture skin samples in Dulbecco's Modified Eagle Medium (DMEM) supplemented with fetal bovine serum, penicillin, and streptomycin. After an initial equilibration period, we topically treat the skin explants with imiquimod cream for multiple consecutive days to induce hallmark psoriatic features. Control groups are treated with a neutral vehicle formulation or left untreated under identical culture conditions.
Our company provides imiquimod-induced ex vivo psoriasis models that enable clients to study mechanisms of psoriasis, evaluate drug efficacy, and develop novel anti-psoriatic drugs.
By integrating histological evaluation, cytokine profiling, and gene expression analysis, we provide imiquimod-induced ex vivo psoriasis models to support clients in identifying and validating biomarkers in psoriasis. These biomarkers serve as critical indicators of therapeutic response, supporting the development of anti-psoriatic drugs.
We offer imiquimod-induced ex vivo models to help clients evaluate whether small molecules, biologics, and topical formulations effectively suppress keratinocyte hyperproliferation, restore normal differentiation, and reduce cytokine-driven inflammation. We also use these models to analyze whether anti-psoriatic drugs modulate key immunological pathways, including the IL-23/IL-17 axis, TNF-α signaling, and JAK-STAT cascade.
Ace Therapeutics specializes in psoriasis models to drive innovation in psoriasis research and therapeutic development. For more information on imiquimod-induced ex vivo psoriasis model development services or to discuss how we can support your research, please do not hesitate to contact us .
