[The pituitary gland unveiled: from the stimulation-secretion coupling to cellular networks wiring].

Abstract

The year 2021 ended with an event of great sadness: the death of Andrée Tixier-Vidal. She was not only a pioneer in cell biology but also the charismatic promoter of stimulating and successful multidisciplinary collaborations. Her achievements led to subsequent major discoveries on both the stimulation-secretion coupling of pituitary endocrine cells and the hitherto unknown organization of these cells into multicellular 3D networks which build-up highly organized pulses of pituitary hormones controlling basic body functions such as growth and reproduction.
