Research theme

Cytokine signaling in the heart

Cardiac homeostasis is maintained by various kinds of cytokines and growth factors. We have been investigating the pathophysiological significances of IL-6 family cytokines in the heart by focusing on STAT proteins, signaling molecules downstream of IL-6 family cytokines. The goal of this study is to develop a novel strategy of cardioprotection utilizing cytokine signaling.

Molecular and cellular basis of myocardial repair/regeneration in mammals

Though the regenerative activity of adult mammalian heart is considered limited in general, myocardial recovery from inflammation-induced injury is frequently observed in the patients with myocarditis. In this project, we will make clear the molecular and cellular mechanisms of myocardial repair/regeneration in the healing process of myocarditis.

Myocardial inflammation after infarction

In response to myocardial injury induced by infarction, inflammatory cells infiltrate into heart and modulate cardiac remodeling; however, the characteristics of the infiltrating cells remain to be precisely defined. The aim of this project is to classify these inflammatory cells into subgroups based on their gene expression profile and elucidate their functions.

Clinical pharmacology in cardiovascular diseases

This project is conducted in collaboration with Laboratory of Clinical Pharmacology and Therapeutics. Our interest is to realize the proper use of the drugs for cardiovascular diseases. We are also interested in onco-cardiology, the research on cardiovascular adverse events caused by anti-tumor drugs.
