Disruption of the developmental factor Otp in the adult forebrain reveals its diverse physiological functions

Maayan Tahor, Yael Kuperman, Tali Nahum, Michael Tsoory, Batya Bejar, Estar Regev, Janna Blechman, Jakob Biran, Alon Chen, Gil Levkowitz

This study investigates the physiological functions of Otp in adult mice, finding impaired stress responses and metabolic changes after conditional deletion.

Neuropeptide oxytocin facilitates its own brain-to-periphery uptake by regulating blood flow dynamics and permeability

Preethi Rajamannar, Janna Blechman, Oren Raz, Gil Levkowitz

This study shows oxytocin regulates blood flow and permeability in the neurohypophyseal system to enhance its own uptake into the bloodstream.

Developmental effects of oxytocin neurons on social affiliation and processing of social information

Ana Rita Nunes, Michael Gliksberg, Susana A. M. Varela, Magda C. Teles, Einav Wircer, Janna Blechman, Giovanni Petri, Gil Levkowitz, Rui F. Oliveira

This study shows that perturbing oxytocin neurons during zebrafish development leads to altered social behavior and neural connectivity in adulthood.
