RIKEN Center for Integrative Medical Sciences Laboratory for Autoimmune Diseases
Team Leader: Kazuhiko Yamamoto (M.D., Ph.D)
Research Summary
Autoimmune diseases such as rheumatoid arthritis (RA) are complex multi-genetic diseases. We have reported multiple RA-associated genes including PADI4, FCRL3, CD244, CCR6 and RTKN2 and SLE-associated genes including AFF1 by genome-wide association studies. We have also studied how these genes are involved in the disease pathogenesis by using molecular biology and animal disease models. Moreover, we are investigating individual’s immune function by genome and transcriptome analysis (eQTL analysis) of human immune cells to dissect their role in the diseases.
