Dr. Moreno studies functional molecular mechanisms of ageing in the neural niche


Numerous studies support that dietary restriction (DR) provides the most effective method against ageing and accompanying morbidity. Importantly, DR offers protective effects against a spectrum of age-related diseases that impose a significant dent in the quality of life and health span of elder populations. Recent studies have shown that the regenerative capacity of stem cell niches is maintained by such dietary interventions. My research focuses on the molecular manipulation of these niches to maintain health span by targeting potential mechanisms of action discovered through DR-like interventions. Furthermore, because many of DR effects appear to be mediated by nutrient sensing brain structures, I focus in local hypothalamic stem cell populations and how their state maintains peripheral homeostasis via autonomic and neuroendocrine responses. 

Dr Moreno completed his PhD in Neuroscience at the Icahn School of Medicine at Mount Sinai, where he studied the role of Creb-binding protein (CBP) in molecular mechanisms of dietary restriction, obesity, and neurodegeneration. During his PhD, he was the recipient of the Ruth L. Kirschstein training grant (T32), as well as an F31 fellowship from the National Institute of Aging. He also obtained a travel scholarship to attend the Aging and Diseases of Aging Keystone Symposium. After his PhD, he joined the psychiatry department as a postdoctoral fellow under the supervision of Prof. Samuel Gandy, where he completed studies on Alzheimer's disease (AD) looking at protein interactions in the gamma-secretase complex. Furthermore, in collaboration with the New York Stem Cell Foundation, he used iPSCs from AD patients to study the effects of insulin signalling in AD as a model of insulin brain resistance.


During my PhD I participated in two collaborative projects: along with Prof. William Coetzee from NYU I studied proteomic complexes of KATP channels in the hypothalamus; with Prof. Michelle Ehrlich I completed studies on the effects of dietary restriction in a mouse model of Huntington's Disease. After my PhD, I developed a project for the Alzheimer's Disease Research Center at Mount Sinai in collaboration with Prof. Christoph Buettner and Prof. Scott Noggle from the New York Stem Cell Foundation. In addition, other collaborators such as Prof. Ottavio Arancio from Columbia University have participated in the development of this project. These latter studies involved the use of iPSC-differentiated neurons to model AD pathology and brain insulin signalling.
