Research Focus
Atopic dermatitis (AD) is a prevalent and complex chronic inflammatory skin condition that typically emerges in early childhood but can affect individuals at any age. Although more than 50% of affected children experience spontaneous remission, growing evidence suggests AD as a lifelong condition characterized by heterogeneous disease trajectories, variable clinical expression, and a persistent risk of relapse. Despite significant advances in understanding AD pathogenesis, the mechanisms governing remission, recurrence, and persistence remain poorly understood, and long-term studies that comprehensively characterize the full spectrum of disease trajectories are still lacking.
We aim to define the cellular and molecular landscapes that shape the course of atopic dermatitis from disease onset and flares to remission and relapse. A central question driving our work is how inflammatory memory is encoded and distributed across circulating and tissue-resident immune cells as well as stromal cells, and how this memory governs long-term disease behavior.
We characterize AD-specific molecular changes across different phases of disease activity and integrate comprehensive registry data on lifestyle, environmental exposures, and related factors to identify the key determinants that influence disease course. By characterizing the molecular mechanisms, specific cell subtypes, and cellular communities that sustain remission or trigger relapse, we aim to generate insights that directly inform the development of new therapies particularly those targeting epigenetic regulatory mechanisms as well as prevention strategies centered on modifiable environmental factors.
Technologies Used
To pursue these questions, we employ state-of-the-art approaches including single-cell multiomics, spatial transcriptomics, proteomics, and epigenetic profiling, applied systematically to patient biomaterials.
Expected Results/Objectives and translational goals
Identifying disease- and cell-state-specific molecular programs that encode inflammatory memory could reveal new drug targets for modulating or reprogramming disease memory toward durable remission. Defining epigenomic, proteomic, and gene expression signatures associated with distinct disease states will support the development of predictive biomarkers capable of stratifying patients by their likelihood of achieving long-term remission or experiencing relapse, enabling personalized treatment decisions, optimized intervention timing, and precision medicine approaches tailored to individual disease trajectories. In parallel, understanding modifiable environmental determinants will inform prevention strategies and lifestyle interventions.
Collectively, our work aims to bridge mechanistic discovery and clinical translation, advancing therapeutic strategies that promote long-term disease resolution and reduce the burden of recurrence in patients with atopic dermatitis
