Profile

Livia obtained a BSc in Pharmacology and Biochemistry, MSc in Neurosciences, and PhD in Pharmacology from University of Sao Paulo, Brazil. In 2005, she worked as a Postdoctoral Researcher with Prof. Carmine Pariante at the Institute of Psychiatry, Psychology and Neurosciences, KCL before moving to the Psychobiology Group at University College London with Prof. Andrew Steptoe. Dr. Carvalho became a lecturer at the William Harvey Research Institute in 2016. She also holds an Honorary Senior Lecturer Post at the Department of Epidemiology and Public Health, UCL.

Most of her publications include investigations on the cellular and molecular aspects involved on the dysregulation of the immune system in patients with mental illnesses, in the absence or presence of physical diseases. She is particularly interested in the antidepressant effect of anti-inflammatory drugs, and in the inflammatory-related mechanisms of action of antidepressants. This translational approach involves a combination of laboratory-based experiments and naturalistic measures in human subjects (heart disease, rheumatoid arthritis or depressed patients) as well as in primary human cells. 

Membership and awards

Dr Carvalho has received several prestigious awards including Young Investigator Awards from the National Alliance for Research in Schizophrenia and Depression (NARSAD), the European Neuropsychopharmacology Society (ECNP), the British Association for Psychopharmacology Non-clinical Award, and the American Psychosomatic Society. 

Reviewer activities

Reviewer Ad-hoc for the following journals Brain Behaviour and Immunity, Psychoneuroendocrinology, Neuropsychopharmacology, among others.

External reviewer for fellowships, project and programme grant for the FWO Research Foundation, Brussels; ME Research, Dunhill Medical Trust, UK; Economic and Social Research Council, UK, Alzheimer Research Trust; National Institute of Health Research, UK, Medical Research Council, UK.

Summary 

Dr Carvalho's research focuses on investigating the biological pathways involved in the role of glucocorticoid hormones and pro-inflammatory cytokines in the biological effects of stress, the pathogenesis of depression, and the molecular mechanisms of antidepressant drugs.

Her projects more specifically revolve around four major themes:

1. The anti-inflammatory and neuroendocrine mechanism of action of antidepressant drugs
2. The antidepressant effect of anti-inflammatory drugs
3. The biological mechanisms involved in the pathogenesis of depression in people with inflammatory illnesses
3. Understanding how inflammatory molecules can signal the brain to alter cognitive function, behaviour and mood.

Studies are carried out in human volunteers (epidemiological cohorts, general and clinical populations) and involve a combination of laboratory-based experiments as well as naturalistic measures. Improved understanding of the pathways linking the central nervous and immune systems is essential for the development of new interventions to prevent and treat mental health, as well as the behavioural and depressive symptoms that commonly accompany physical illnesses. It could also influence treatment decisions and provide alternative targets for potential new antidepressant agents.
