In our laboratory, we focus on immune receptors and their signaling molecules that activate signals via ITAM motifs, and are working to elucidate the physiological functions of these molecules using molecular biological and genetic engineering techniques. By doing so, we aim to discover novel mechanisms involved in the onset and progression of various diseases such as infectious diseases, cancer, and dementia, and to establish a new concept of treatment.
