Biological timing: Linking the circadian clock to the season

03/01/2023

The circadian clock is thought to provide the internal time reference for measuring day length, allowing organisms to prepare in advance for the coming winter and summer. A new study sheds light on the neural link between the circadian clock and seasonal timing.

Receptor deorphanization in an echinoderm reveals kisspeptin evolution and relationship with SALMFamide neuropeptides

09/16/2022

During puberty our bodies undergo changes whereby a child's body matures into an adult body capable of sexual reproduction. In some people, however, the onset of puberty is delayed and genetic analysis of this condition has provided insights into the hormonal mechanisms that control sexual maturation. Thus, in 2003 it was discovered that onset of puberty is triggered by the release of a hormone in the brain (a neurohormone) known as kisspeptin, which then exerts its effects by binding to a protein known as the kisspeptin receptor. But when did kisspeptin and its receptor originate in the evolutionary history of life on earth?

Endocrine cybernetics: neuropeptides as molecular switches in behavioural decisions

09/16/2022

This co-authored review by Dick Nässel and Meet Zandawala discusses the role of neuropeptides as molecular switches in behavioural decisions. Classical work by Norbert Wiener (1948) laid the foundations for cybernetics - the study of control and communication in the animal and the machine. Nobel laureate Roger Guillemin used the generic name "cybernin" to refer to peptides used for paracrine signaling. The authors coin the term "endocrine cybernetics" which is the regulation or governance of behavior by paracrine chemical signaling.

The Gain and Loss of Cryptochrome/Photolyase Family Members during Evolution

09/13/2022

The cryptochrome/photolyase (CRY/PL) family represents an ancient group of proteins fulfilling two fundamental functions. While photolyases repair UV-induced DNA damages, cryptochromes mainly influence the circadian clock.

How the brain and the circadian clock shape behaviour

Group picture chair

How the brain and the circadian clock shape behaviour is the fundamental question behind our research projects. Our primary model system is the genetically amenable fruit fly, though we also do work on other insects. For more information on the current lines of research, please check out the links below for the different groups at our chair.
