[An Investigation of Substances Influencing Adipocyte Function].

ABSTRACT

Adipose tissue plays a central metabolic role in systemic energy metabolism via nutrient exchange and secretion of adipose-derived hormones and cytokines. Adipose tissue dysfunction increases the risk of developing conditions, including type 2 diabetes, coronary artery disease, stroke, and cancer, ultimately shortening healthy lifespan. Maintaining adipose tissue functions has recently garnered attention as a means to extend healthy life expectancy. We previously developed a T-cell activation-inhibitory assay, which facilitates efficient selection of candidate substances for extending healthy lifespan. Using this assay, we identified two candidate substances Cynandione A (CA), a major component of Cynanchum wilfordii, and N-caffeoyltryptophan (NCT) found in coffee. This review summarizes recent findings regarding the effect of CA and NCT on adipocyte (the primary cells in adipose tissue) function, and their potential contribution to extending healthy life expectancy.
