ICGR-V - 5th International Conference on Gonadotropins and Receptors

March 12, 2024 - March 15, 2024

Hôtel Univers
5 boulevard Heurteloup
37000 Tours


Gonadotropins and their receptors are master regulators of development and reproduction. Together with other glycoprotein hormones, such as kisspeptin and GnRH, they trigger multiple signaling cascades and intracellular events recently depicted using novel technological and scientific tools. Our knowledge in the field advanced significantly in the last decade, where the classic view of the hypothalamus-pituitary-gonadal axis has been expanded with the addition of novel signaling cascades, potential partner proteins and target tissues. These new findings provided new potential therapeutic applications for reproductive purpose and cancer treatment.

This international conference is organised in the framework of the BIOPHARMACEUTICALS ARD CVL Programme.
