Research
Itamar Harel is a researcher in the field of biology, specifically known for his work in the areas of aging and disease (reviewed in[1][2][3][4]). Harel's research focuses on understanding the mechanisms of aging and longevity, with a particular interest in using the emerging African turquoise killifish (Nothobranchius furzeri) model to study these processes.[5][6][7][8] His work aims to uncover the biological pathways that influence aging and to develop potential interventions to promote healthy aging.
Harel pioneered a genetic platform in the naturally short-lived turquoise killifish[9][10], which lives only twice as long as Drosophila. By exploring protein aggregation with age, he revealed naturally occurring prion-like behaviors that propose a novel mechanism for damage propagation during aging[11][12]. Using this emerging vertebrate model, he explores how aging is scaled between species, what mediates its sexual dimorphism, and why longevity is proportional to other species-specific traits (such as age at maturity).
In a series of discoveries, the Harel lab revealed novel mechanisms that regulate vertebrate longevity. They identified how reproduction might impact vertebrate aging by demonstrating that the germline itself can regulate longevity and stress resistance in a sex-specific manner.[7][13] Additionally, the Harel lab discovered of a novel vertebrate longevity mechanism linked to energy homeostasis via the AMP-activated protein kinase (AMPK) pathway.[8][14] Research in Harel's laboratory also focuses on developing advanced genetic tools, including lineage tracing, modeling of sporadic age-related cancers, and precise control of pituitary hormones in-vivo[15][16][17].
