The two principal focuses of our research are the Central Control of Energy Homeostasis, and the Neurobiology of Reproduction. Among our pioneering studies are: (i) the demonstration that tanycytes, specialized ependymoglial cells lining the floor of the third ventricle, are responsible for the transport of peripheral metabolic signals such as leptin across brain barriers into the metabolic brain, elucidating a mechanism for leptin resistance in obesity; (ii) the discovery that endothelial cell-derived chemotropic factors of the semaphorin family control GnRH axonal growth in the adult neuroendocrine brain, thus modulating fertility; (iii) the finding that a discrete neuronal population that releases nitric oxide in the preoptic region of the hypothalamus is vital for the rapid integration and transmission of both gonadal and metabolic signals within the neuroendocrine brain, and thus plays a key role in the timing of puberty onset; and (iv) the uncovering that a dramatic switch in miRNA expression patterns in infantile GnRH neurons inverts the balance between inductive and repressive signals, triggering increased hypothalamic GnRH expression and controlling the crucial transition from the early infantile phase, when its levels are low, to the GnRH-fuelled run-up to puberty.
