Professor Dong-Sup Lee's research lab specializes in translational immunology and nanomedicine, focusing on the molecular mechanisms of fibrotic and inflammatory diseases, particularly in the lung and kidney. The lab develops smart nanomaterials for precision imaging and therapy, with a strong emphasis on photodynamic immunotherapy and targeted delivery. It also investigates key immune regulators such as STING, VISTA, and uteroglobin in disease progression, aiming to identify novel therapeutic targets for fibrosis, nephropathy, and cancer.

Pulmonary fibrosis is a potentially life-threatening disease that may be caused by overt or asymptomatic inflammatory responses. However, the precise mechanisms by which tissue injury is translated into inflammation and consequent fibrosis remain to be established. Here, we show that in a lung injury model, bleomycin induced the secretion of IL-6 by epithelial cells in a transglutaminase 2 (TG2)-dependent manner. This response represents a key step in the differentiation of IL-17-producing T cel
Smart phototheranostic nanomaterials are of significant interest for high-quality imaging and targeted therapy in the precision medicine field. Herein, a nanoscale photosensitizer (NanoPcM) is constructed through the self-assembly of morpholine-substituted silicon phthalocyanine (PcM) and albumin. NanoPcM displays a turn-on fluorescence depending on the acid-induced abolition of the photoinduced electron transfer effect (change in molecular structure) and disassembly of the nanostructure (change
Uteroglobin (UG) is an anti-inflammatory/immunomodulatory protein. Targeted disruption of UG rendered mouse glomerulonephritis resembling immunoglobulin (Ig)A nephropathy (IgAN). Sequence analysis on exon 1 of UG showed several putative binding sites for transcription factors, and polymorphisms in this site might influence the expression level of UG as a competitive protein. We speculated that the single nucleotide polymorphism at the 38th nucleotide (A to G) from the transcription initiation si
Severe glomerular injury ultimately leads to tubulointerstitial fibrosis that determines patient outcome, but the immunological molecules connecting these processes remain undetermined. The present study addressed whether V-domain Ig suppressor of T cell activation (VISTA), constitutively expressed in kidney macrophages, plays a protective role in tubulointerstitial fibrotic transformation after acute antibody-mediated glomerulonephritis. After acute glomerular injury using nephrotoxic serum, tu
Modulating target proteins via the ubiquitin-proteasome system has recently expanded the scope of pharmacological inventions. Stimulator of interferon genes (STING) is an auspicious target for immunotherapy. Seminal studies envisioned the importance of STING as well as the utility of its agonists in immunotherapy outcomes. Herein, we suggest UPPRIS (upregulation of target proteins by protein-protein interaction strategy) to pharmacologically increase cellular STING levels for improved immunother
Our new oncolytic vaccinia virus platform, which expresses human CD55 protein on its membrane, prolonged viral survival by protecting against complement-mediated lysis and by evading neutralization by vaccinia virus-specific antibodies; this may provide a continuous antitumor efficacy until a complete remission has been achieved. Such a platform may expand the target cancer profile to include deep-seated cancers and widespread metastatic cancers.
