Juvenile behavioral alterations and sex-dependent deficits in hippocampal neurogenesis following early-life stress in rats

Ailen Alba Colapietro, Jazmín Grillo Balboa, Karen Melany Stefani, Marianela Noemí Ceol Retamal, María Eugenia Pallarés, Marta Cristina Antonelli, Silvina L. Diaz

This study examines early behavioral and neuroplastic changes in juvenile rats exposed to early-life stress, finding male-specific deficits in hippocampal neurogenesis and behavioral impairments.

Nanoliposomal Omega-3 Fatty Acids Promote Adult Hippocampal Neurogenesis through the BDNF/TrkB Pathway in C57BL/6 Mice

Rocío Beatriz Foltran, Gabriela Diaz, Karen Melany Stefani, MS Feliu, Anabel Impa Condori, Ailen Alba Colapietro, Daniela Romina Montagna, Vanina Ambrosi, MF Godoy, Silvina Mabel Guidi, Mariana Nanni, Silvina L. Diaz

This study shows that nanoencapsulated omega-3 fatty acids improve hippocampal neurogenesis in mice by enhancing BDNF/TrkB pathway activity and Fabp5 expression.
