The immune system is essential to protect our body from pathogens. The immune system requires strict control because its breakdown causes diseases. Our research focuses on understanding the human immune system in health and disease. We aim to define “the norm” of the human immune system, elucidate the pathophysiology of various diseases, and develop new therapeutic strategies.
Research and Education
While research with mouse models has contributed significantly to our understanding of immunology, there is a noticeable limitation in translating mouse findings to humans. Indeed, now we realize that there are many differences in the immune system between mice and humans. Therefore, the precise immune mechanisms in humans can only be elucidated by human immunology research using human specimens. Experimental approaches for human immunology have dramatically evolved during the past 5-10 years, thanks to advancements in technology and analytical tools. Whereas blood samples have been the main specimen for human immunology research, we can now analyze the immune cells isolated from tiny tissue samples, such as inflamed lesions of autoimmune diseases and cancer tissues, at a single-cell resolution. We perform the most advanced human immunology research using the state-of-the-art equipment and tools. We aim to elucidate “the norm” of the human immune system and identify “abnormals” in the immune system in various human diseases by using samples obtained from healthy subjects and patients. As of 2022, our target diseases include infectious diseases, vaccines, cancer immunity, autoimmune diseases, and allergies. We are particularly interested in human liver immunology.
