An interdisciplinary project with scientists and clinicians from across the Medical Sciences Division used bipolar patient-derived fibroblasts to gain a deeper understanding into patient circadian rhythms, and how these rhythmic changes could predict lithium sensitivity in bipolar disorder.

Department of Pharmacology's Vasudevan Laboratory, in an interdisciplinary project with scientists and clinicians from across Department of Psychiatry, Nuffield Department of Clinical Neurosciences, Sir William Dunn School of Pathology, MRC Weatherall Institute of Molecular Medicine (Radcliffe Department of Medicine), and the Oxford StemBANCC have used bipolar patient-derived fibroblasts to gain a deeper understanding into patient circadian rhythms, and how these rhythmic changes could predict lithium sensitivity in bipolar disorder.

Bipolar disorder is a chronic neuropsychiatric condition associated with mood instability, where patients present significant sleep and circadian rhythm abnormalities. Currently, the pathophysiology of bipolar disorder remains elusive, but treatment with lithium continues as the benchmark pharmacotherapy, functioning as a potent mood stabilizer in most, but not all patients. Lithium is a well-documented circadian modulator. Based on this, we sought to investigate whether lithium differentially impacts circadian rhythms in bipolar patient cell lines and crucially if lithium’s effect on the clock is fundamental to its mood-stabilizing effects.

Oxford and Oracle partner to speed identification of COVID-19 variants

The fast spread of the highly infectious Delta variant underscores the need for faster identification of COVID-19 mutations. Uniting governments and medical communities in this challenge, the University of Oxford and Oracle’s Global Pathogen Analysis System (GPAS) is now being used by organizations on nearly every continent. Institutions using the platform include: the University of Montreal Hospital Centre Research Centre, the Institute of Public Health Research of Chile, the Oxford University Clinical Research Unit in Vietnam, the Institute of Clinical Pathology and Medical Research – New South Wales Pathology, and Oxford Nanopore Technologies. GPAS is also now part of the Public Health England New Variant Assessment Platform.
