Current research confronts significant obstacles as no single preclinical model fully replicates the complex pathophysiology of human psoriasis, hindering the development of effective interventions.
Dermatologists and translational scientists have long relied on a spectrum of skin disease models in psoriasis research—from imiquimod-induced inflammation in rodents to grafted human skin on immunodeficient mice—to explore immune cell infiltration and cytokine network activation. However, a new analysis emphasizes the need for using complementary models, since individual systems fall short of capturing interpatient variability, chronicity, and the interplay of genetic and environmental triggers.
This tension is compounded by the promise of genome editing in dermatology, particularly CRISPR/Cas9 platforms that enable targeted edits of key psoriasis susceptibility loci. As noted in the earlier report on complementary models, CRISPR/Cas9 facilitates precise manipulation of pathways implicated in epidermal hyperplasia and immune dysregulation, allowing construction of tailored systems that mirror patient-specific molecular signatures.
The convergence of advanced genetic tools with humanized systems for psoriasis—such as xenografts seeded with patient-derived keratinocytes and immune cells—offers a new frontier for translational research. By integrating CRISPR-modified cells into these platforms, researchers can interrogate the functional impact of defined mutations, screen novel psoriasis treatment candidates, and evaluate potential off-target effects before clinical trials, though the predictive accuracy requires further validation. Such hybrid approaches promise to bridge persistent gaps between bench discoveries and therapeutic outcomes.
As these technologies mature, they may redefine our approach to psoriasis treatment by enabling personalized risk stratification and accelerating the path from mechanistic insight to clinical efficacy.
