Introduction

Department of Aging Research is founded in the Research Institute of the National Center for Geriatrics and Gerontology (http://www.ncgg.go.jp). We focus on the molecular and cellular mechanisms underlying aging and senescence, and promote the cutting-edge researches to profoundly understand and overcome the aging-associated declines and diseases.

Research Projects

  1. Molecular mechanisms of age-dependent functional decline in immune system and the approach for its recovery
    Concerning the functional decline of host defense associated with aging, we are focusing on studying the aging of acquired immune system which is closely related to vaccination and immune therapy using antibodies. Specifically, we aim to be disclosed the molecular mechanisms of functional decline in elderly immune system focusing on aging-related genes with lymphocyte specific expression at the molecular, cellular or even individual level using the animal models. Currently, we are working on the in vitro and in vivo functions of the Zizimin family genes in various immune cells, and finally we hope our study will reach the realization of recovery capable to maintain adequate immunity against infectious diseases that the elderly suffer.

  2. Pathophysiological roles of cellular senescence
    Cellular senescence is triggered by sustained and irreparable damage that leads to the activation of tumor suppressor pathways. Increasing amount of evidence suggests that cellular senescence contributes to tissue aging. Senescent cells accumulate in many tissues during aging and are considered to underlie several aging-associated pathologies through their non-cell autonomous function, SASP (senescence-associated secretory phenotype). We thus study the molecular and cellular mechanisms through which senescent cells contribute to tissue aging using model animals.
