Scientific contributions 
Alain Prochiantz has been working since the early 1980s in the field of molecular neurobiology, particularly on the processes of morphogenesis and nerve cell differentiation. He did his first major work at the Collège de France with Jacques Glowinski on the development and in vitro maturation of dopaminergic neurons in the mesencephalon.

His laboratory having moved to the École normale supérieure, he then became interested in the molecular signals responsible for certain neuronal morphogenesis processes and, in 1991, highlighted in particular the role of homeoboxes of certain transcription factors (but also of different extracellular matrix proteins such as tenascin, glycoaminoglycans...) in these phenomena.

As was then fully accepted in the scientific community, he proposes that cascades of regulation of homeotic genes (of the Hox family) are potentially involved in many stages of neuronal differentiation, neurite growth, neuronal polarity... However, going against a certain number of knowledge, or even dogmas in the field of molecular biology, he reports that domains of transcription factors, or even whole proteins such as Hox5, can be internalized in a cell and therefore suggests the possible secretion of a given transcription factor by a nerve cell A that can be internalized by a neighbouring cell B and have a biological effect on it. To clearly demonstrate this, he and his team are interested in the homeoprotein Engrailed of the Hox gene family involved in
