Laura Dearden
Talk: Early life programming of obesity via a hypothalamic miRNA involved in fatty acid sensing
When: 2pm, Tuesday 5 September 2023, Symposium: Neuroendocrine adaptations during pregnancy & development (view programme)
Laura Dearden is a Royal Society Dorothy Hodgkin Research Fellow at the Institute of Metabolic Science, University of Cambridge. Prior to her current appointment she was a Sir Henry Wellcome Fellow in the laboratory of Professor Susan Ozanne. Laura undertook her PhD with Dr Nina Balthasar at the University of Bristol, researching how the hypothalamus integrates and responds to nutrient signals from the periphery. During her PhD, Laura became interested in how these processes might be programmed pathologically by exposure to sub-optimal nutrition in pregnancy- a time when the fetal hypothalamic development is vulnerable to disruption. Laura’s research group is combining molecular and physiological methods to identify the influences of the in utero metabolic environment, with a focus on insulin, on the development and subsequent function of hypothalamic feeding circuits.
Elodie Desroziers
Talk: Unusual suspect: role of microglia in the neuroendocrine disorder polycystic ovary syndrome
When: 9am, Wednesday, 6 September 2023, Symposium: Reproductive Neuroendocrinology (view programme)
Dr Elodie DESROZIERS is an assistant professor at Sorbonne University since September 2021. She is a principal investigator in the team “Neuroplasticity of reproductive behaviors” led by Dr Sakina Mhaouty-Kodja at the Institut de Biologie Paris Seine, Paris, France. Her research interests always focused on the effect of sex steroids on the brain in order to regulate fertility and sexual behaviours. She obtained her PhD in Life Science and Health in December 2011 from the University Francois Rabelais of Tours, France where she studied the ontogenesis of Kisspeptin neurons, important neuronal regulators of reproductive function. Then, during her first post-doctoral position in Dr Julie Bakker laboratory (2012-2015, University of Liege, Belgium), she showed a role for prepubertal progesterone signaling in the feminization of the brain. In 2015, she joined the Center for Neuroendocrinology ( CNE) at the University of Otago New Zealand. First for a postdoctoral position in the A/P Rebecca Campbell laboratory (2015-2020) and then as Principal Investigator (2021-2022). Within the CNE, her research focused on the role of the brain in the most common infertility disorder in women of reproductive age worldwide: Polycystic Ovary Syndrome (PCOS). She showed a role for arcuate GABAergic neurons in the establishment of PCOS-like features (2015-2018). Then, she studied the role of prenatal androgen excess in sexual dysfunction in a preclinical mouse model of PCOS (2018-2021). In 2020, she was awarded an early career development grant, the Hercus Fellowship, from the Health Research Council of New Zealand. This funding was dedicated to the study of the role of microglia in fertility regulation and PCOS which will be the topic of her talk at this BSN annual meeting. Finally, in her new permanent position at Sorbonne University, she is pursuing her investigation on the role and effect of sex steroids signaling on glial cells within the brain associated with reproductive function and behaviors.
Helen Eachus
Talk: Elevated glucocorticoid: from adaptive plasticity to allostatic overload
When: 2pm, Tuesday 5 September 2023, Symposium: Neuroendocrine adaptations during pregnancy & development (view programme)
Helen Eachus is a post-doctoral fellow at the Living Systems Institute, University of Exeter.
Since Helen's Bachelors degree, she has been interested in how exposure to stress shapes the brain and behaviour across the life course. Helen carried out my PhD at the University of Sheffield, studying gene X environment interactions using a zebrafish model. Helen's work investigated how a genetic risk factor for schizophrenia, DISC1, modulates development and function of the hypothalamus, the critical regulator of the vertebrate stress response. Following this, she began my post-doctoral study at Sheffield, working on two different projects. The first project focused on epigenetic embedding of stress in the zebrafish brain, whilst the second project involved characterisation of a zebrafish disease model of impaired stress hormone biosynthesis known as congenital adrenal hyperplasia. Now based at the University of Exeter as a post-doctoral fellow, Helen has continued to develop her interest in stress regulation of brain plasticity. Her current work is focused on how exposure to elevated glucocorticoid during early life alters the trajectory of hypothalamic development and function, using a zebrafish model.

Talk: Decoding the Biological Clock: Exploring the Genetics of Human Reproductive Ageing
When: 5pm, Monday 4 September 2023, Public Lecture (view programme)
Anna is a Professor of Human Genetics at the University of Exeter. She completed her PhD in 1994 and did post-doctoral studies at the University of Southampton working on the genetics of Fragile X syndrome. A chance finding resulted in her specialising in the field of reproductive ageing, when she led a study that found an association between very early menopause and the gene that causes Fragile X. Anna moved to the University of Exeter in 2005 where she expanded her research programme to include multifactorial inheritance of reproductive ageing and associated traits. She has established an international reputation in reproductive genetics, co-leading the ReproGen consortium of around 40 studies worldwide.
Valerie Simonneaux
Talk: Neuroendocrine mechanisms of seasonal adaptation
When: 11am, Monday 4 September 2023, Mortyn Jones Lecture (view programme)
Valerie Simonneaux is a CNRS director of research, head of the team “Neuroendocrine rhythms in reproduction” at the Institute of Cellular and Integrative Neurosciences in Strasbourg, France. She has a broad background in the neuroendocrinology of biological rhythms. Her current focus is on the circadian and seasonal control of reproduction.
In the last few years her team has reported that hypothalamic neuropeptides of the RF-amide family (kisspeptin and RFRP-3) are pivotal relays between seasonal (melatonin, circannual clock) and daily (clock outputs) time cues and the central regulation of GnRH neurons. Her team is currently investigating how these neuroendocrine pathways are altered following circadian disruption or exposure to endocrine disruptors, and during long term regulation such as hibernation, circannual timing, maternal programming.
Besides this research activity, she is the director of the Strasbourg’s Interdisciplinary Institute of Neuroscience, she has been the president of the Society of NeuroEndocrinology and is now member of the council of the French Société des Neurosciences and the European Biological Rhythms Society.
Manuel Tena-Sempere
Talk: Exploring the neuroendocrine basis of puberty and reproduction: Kisspeptins and beyond
When: 11am, Tuesday 5 September 2023, Alison Douglas Lecture (view programme)
Manuel Tena-Sempere is a Professor of Physiology at the Turku Centure for Disease Modelling at the University of Turku.
Manuel's research group is interested in deciphering the neuroendocrine and molecular mechanisms responsible for the control of puberty and reproductive function, and how these finely interplay with the systems governing body weight and metabolic homeostasis. In this context, they are actively working in the characterization of the role of different neuropeptide systems in the neurohormonal regulation of puberty onset and fertility, with special attention to the analysis of the functions of kisspeptins and their interactions with other central (e.g., neurokinin B, other tachykinins, melanocortins, GnIH) and peripheral (e.g., leptin, sex steroids) regulators, as well as modulation by nutritional and metabolic cues. More recently, his group has become interested in disclosing the role of novel regulatory mechanisms, such as miRNAs, epigenetics and cellular energy sensors, in the joint control of metabolism and reproduction, and how these interplay with central neuropeptide networks (specially kisspeptins). This basic knowledge, generated mostly by the use of at-the-edge preclinical (rodent) models and techniques in neuroendocrine research has set the basis for implementation of translational projects, currently running in Manuel's group, targeting the metabolic and reproductive consequences of obesity-induced hypogonadism, as well as improved strategies for the diagnosis and treatment of common reproductive disorders, such as polycystic ovarian syndrome.
