Laboratory for Immunochaperones

Our team proposes to call intracellular molecular chaperones as immunochaperones when they are playing roles in a variety of immune response. We examine novel functions of these immunochaperones in immunity. Particularly we focus on those in antigen processing linked with protein degradation by ubiquitin-proteasome system, and in activation of innate and acquired immunity. Besides, unpredictable observation associated with chaperones found in ongoing experiments will drive us to dig those up to construct a new paradigm of a world of molecular chaperones in immunity and life science.
