In Vitro
Morcamilast (ME3183) potently inhibits the production of proinflammatory cytokines and chemokines induced by stimulants in whole blood cell cultures from patients with plaque psoriasis and healthy volunteers, with a potency 5 to 40 times higher than that of apremilast[2].
Morcamilast potently inhibits TNF-α production in lipopolysaccharide-stimulated peripheral blood mononuclear cells (PBMCs) from patients with psoriasis, and its inhibitory activity is 114-fold stronger than that of apremilast[3].
Morcamilast (pretreated for 1 h; stimulated with LPS at 1 ng/mL for 18 h) potently inhibits the production of psoriasis-related cytokines TNF-α, IL-12/23p40 and IL-23 in LPS-induced human PBMCs, with IC50 values of 0.648 nM, 1.96 nM and 98.4 nM, respectively[4].
Morcamilast exhibits IC50 values of 1.28 nM, 2.33 nM, and 1.63 nM against PDE4A1A, PDE4B1, and PDE4D2, respectively, and shows weak activity against most other PDE family enzymes[4].
Morcamilast (48 h) potently inhibits the production of psoriasis-associated IL-17A (IC50 28.5 nM) and Th2 cytokines IL-4 (IC50 1.15 nM), IL-5 (IC50 33.0 nM), and IL-13 (IC50 88.4 nM) in stimulated human T cells[4].

Collagen-Induced Arthritis
Collagen-induced arthritis (CIA) is an autoimmune murine model of rheumatoid arthritis in which immunization with type II collagen (CII) emulsified in an adjuvant induces a T cell- and autoantibody-driven inflammatory arthritis characterized by synovial hyperplasia, immune cell infiltration, and joint destruction. The model typically relies on genetically susceptible mouse strains (e. g. , DBA/1) and reproduces key features of human rheumatoid arthritis, including anti-collagen immune responses and progressive joint inflammation. Disease onset generally occurs within ~3-4 weeks after immunization, depending on antigen/adjuvant combinations and protocol variation. The immunopathology is driven by adaptive immune activation against CII, leading to systemic and local joint inflammation mediated by pro-inflammatory cytokines and effector immune cells, making CIA a standard preclinical platform for evaluating immunomodulatory and anti-arthritic interventions.

Imiquimod-Induced Psoriasiform Dermatitis
Imiquimod (IMQ)-induced psoriasiform dermatitis is a widely used murine model in which topical application of IMQ, a Toll-like receptor 7 (TLR7) agonist, triggers innate immune activation in the skin and induces a psoriasis-like inflammatory cascade characterized by epidermal hyperplasia, immune cell infiltration, and cytokine production dominated by the IL-23/IL-17 axis. This inflammatory response is mediated through activation of dendritic cells and downstream induction of IL-23, IL-17A, IL-22, and related pro-inflammatory mediators, recapitulating key features of human plaque psoriasis and enabling mechanistic and therapeutic studies. The model is commonly induced using Aldara (5% IMQ cream) applied topically to murine skin, resulting in rapid onset of erythema, scaling, and thickening that can be quantified as disease severity indices and validated histologically.

TPA/Croton Oil Ear Edema and Dermatitis
The TPA (12-O-tetradecanoylphorbol-13-acetate) and croton oil-induced mouse ear edema model is a well-established acute cutaneous inflammation system used to evaluate topical anti-inflammatory activity by measuring edema formation, neutrophil infiltration, vascular permeability, and cytokine-mediated skin responses in vivo. The inflammatory response is triggered by topical application of phorbol esters (TPA) or croton oil constituents, leading to rapid activation of protein kinase C signaling, leukocyte recruitment, and increased vascular permeability, which can be quantified by ear thickness, weight, dye extravasation, and biochemical markers such as myeloperoxidase (MPO) activity and pro-inflammatory mediators in ear tissue homogenates. This model is widely used for screening anti-inflammatory agents, where reductions in edema and inflammatory biomarkers reflect suppression of acute dermal inflammation and immune cell infiltration. Histological evaluation typically confirms epidermal
