Reseach of the RNA Biology Research Group

The main focus

Our ongoing research projects aim to elucidate the functions of RNA-based mechanisms in chronic inflammatory diseases, such as atopic dermatitis, psoriasis, and asthma. Specifically, we are interested in how miRNAs and RNA modifications regulate immune and epithelial cell responses, epithelial barrier functions, and proliferation and differentiation of epithelial cells in these diseases. Our second research goal is to develop more efficient and safe delivery methods for potentially therapeutic miRNAs and mRNA into immune cells and inflamed epithelium using cell-penetrating peptides. Additionally, we participate in collaborative projects that seek to discover and functionally characterize novel molecular factors involved in the development of chronic inflammatory skin diseases and asthma.
