Summary

Yosuke Kunishita, M.D., Ph.D., was awarded his medical degree in March 2011 from Asahikawa Medical University, Asahikawa, Japan. He started working as an adult rheumatologist at Yokohama City University, Yokohama, Japan in 2013. During his clinical work, Dr. Kunishita learned that the causes and pathophysiology of many autoimmune and inflammatory diseases still need to be established. His desire to understand more about immunology led him to graduate school in 2015. 

In graduate school, Dr. Kunishita researched the dysfunction of TRIM21 in systemic lupus erythematosus (SLE) using mouse models and human specimens. He received his Ph.D. in Medical Science from Yokohama City University Graduate School of Medicine, Yokohama, Japan in 2020. Before coming to the NIH, he conducted several research studies using clinical data, human specimens, and cell lines, focusing on rheumatoid arthritis, SLE, and VEXAS syndrome. 

In 2023, he came to the NIH as a postdoctoral visiting fellow to work with Dr. Daniel L. Kastner in the Inflammatory Disease Section, NHGRI, NIH, and Dr. Pravitt Gourh in the Scleroderma Genomics and Health Disparities Unit, NIAMS, NIH.

Research Statement

The goal of Dr. Kunishita's research project aims to search for novel pathogenic germline and somatic mutations in adult-onset inflammatory disease to elucidate the pathogenesis, search for therapeutic targets, and develop therapies.
