Journal ArticleDOI
The neural cell adhesion molecule NCAM is an alternative signaling receptor for GDNF family ligands.
TL;DR: The results uncover an unexpected intersection between short- and long-range mechanisms of intercellular communication and reveal a pathway for GDNF signaling that does not require the RET receptor.
Journal ArticleDOI
Learning-associated activation of nuclear MAPK, CREB and Elk-1, along with Fos production, in the rat hippocampus after a one-trial avoidance learning: abolition by NMDA receptor blockade
Martín Cammarota,Lia R. M. Bevilaqua,Lia R. M. Bevilaqua,Patrícia Ardenghi,Gustavo Paratcha,Miguelina Levi de Stein,Ivan Izquierdo,Jorge H. Medina +7 more
TL;DR: Evidence is provided for the participation of hippocampal PKA/CREB and MAPK/Elk-1 pathways, via activation ofNMDA receptors, in memory formation of a one-trial avoidance learning in rats, and NMDA receptors appear to be a necessary upstream step for the activation of these intracellular cascades during learning.
Journal ArticleDOI
Released GFRα1 potentiates downstream signaling, neuronal survival, and differentiation via a novel mechanism of recruitment of c-Ret to lipid rafts
Gustavo Paratcha,Fernanda Ledda,Louise Baars,Muriel Coulpier,Valerie Besset,Jonas Anders,Rizaldy P. Scott,Carlos F. Ibáñez +7 more
TL;DR: The results provide an explanation for the tissue distribution of GFRalpha1 and support the physiological importance of c-Ret activation in trans as a novel mechanism to potentiate and diversify the biological responses to GDNF.
Journal ArticleDOI
Endocannabinoids regulate interneuron migration and morphogenesis by transactivating the TrkB receptor
Paul Berghuis,Marton B. Dobszay,Xinyu Wang,Sabrina M. Spano,Fernanda Ledda,Kyle M. Sousa,Gunnar Schulte,Patrik Ernfors,Ken Mackie,Gustavo Paratcha,Yasmin L. Hurd,Tibor Harkany +11 more
TL;DR: It is found that Src kinase-dependent TrkB receptor transactivation mediates endocannabinoid (eCB)-induced chemotaxis in the absence of BDNF, and eCBs suppress the BDNF-dependent morphogenesis of interneurons, and this suppression is abolished by SRC kinase inhibition in vitro.
Journal ArticleDOI
GDNF and GFRα: a versatile molecular complex for developing neurons
Gustavo Paratcha,Fernanda Ledda +1 more
TL;DR: Emerging evidence indicates a prominent role of GDNF and GFRalpha in the control of neuroblast migration and chemoattraction and in the formation of neuronal synapses by a new mechanism of ligand-induced cell adhesion, highlighting the importance of this versatile molecular complex for nervous system development, function and regeneration.
