The Cambridge Centre for Myelin Repair (CCMR) and Cambridge Neuroscience are delighted to invite you to Professor Alexei Verkhratsky’s seminar at the Jeffrey Cheah Biomedical Centre. The title of the talk is: ‘Astrocytic decline and paralysis, rather than reactivity, contribute to brain ageing and age-dependent neurodegenerative diseases.’

Alexei Verkhratsky is an internationally recognised scholar in the field of cellular neurophysiology, best known for his contributions to our knowledge of the physiology and pathophysiology of neuroglia. He was one of the first to discover the specific expression of neurotransmitter receptors in astrocytes and their activation in situ by physiological stimulation. He demonstrated (with H. Kettenmann) matching patterns of neuronal and glial receptors, thus providing the basis for the concept of active and reciprocal neuronal-glial communications. He demonstrated that these receptors are connected to calcium-mediated signalling cascades, which led to the important concept of glial calcium excitability. Subsequently he developed the concept of sodium ions as a specific signalling molecule controlling local homeostatic responses of astrocytes. These discoveries have made a major contribution to the development of a new doctrine of the fundamental role of neuroglia in brain function. Verkhratsky also pioneered the emerging field of neurogliopathology, having characterised astroglial asthenia and paralysis as key pathogenetic steps in age-dependent neurodegenerative diseases. In a series of highly cited conceptual papers he outlined basic principles of glial physiology and pathophysiology, which significantly influenced this rapidly developing area of neuroscience.

This seminar promises to be an excellent event and we hope you can either attend in person, in the Lecture Theatre of the Jeffrey Cheah Biomedical Centre, or (if you are a UoC member) online via Zoom (password: 141189).

Programme: Chair’s introduction, Professor Alexej Verkhratsky’s talk, questions and discussion.

Following the seminar, at 17:30, drinks and canapes will be available in the exhibition area to extend attendee’s discussions.

We look forward to seeing you there!

Date: 
Thursday, 29 June, 2023 - 16:30 to 17:30
