Transfer of optogenetic vectors into the brain of neonatal animals to study neuron functions during subsequent periods of development by D. A. Lanshakov, U. S. Drozd, T. A. Zapara, N. N. Dygalo

“…The same experiments with older animals, 60 days after the neonatal opto-channel gene transfer, revealed no noticeable expression of this channel or photoactivation of target neurons of the hippocampus. Thus, neonatal administration of a viral vector carrying an opto-channel gene is suitable for the study of brain neurons in rats of juvenile age, and requires additional control for gene expression during subsequent periods of development.…”

Aspects of Growth Hormone and Insulin-Like Growth Factor-I Related to Neuroprotection, Regeneration, and Functional Plasticity in the Adult Brain by N. David Åberg, Katarina Gustafson Brywe, Jörgen Isgaard

“…Apart from the neuroprotective effects of GH and IGF-I posited in different experimental models of CNS injury, IGF-I has been found to increase progenitor cell proliferation and new neurons, oligodendrocytes, and blood vessels in the dentate gyrus of the hippocampus. It appears that the MAPK signaling pathway is required for IGF-Istimulated proliferation in vitro, whereas the PI3K/Akt or MAPK/Erk signaling pathway appears to mediate antiapoptotic effects. …”
