Semax Stimulates Neurogenesis.Â
“Here, we found that a single application of Semax (50 μg/kg body weight) results in a maximal 1.4-fold increase of BDNF protein levels accompanying with 1.6-fold increase of trkB tyrosine phosporylation levels, and a 3-fold and a 2-fold increase of exon III BDNF and trkB mRNA levels, respectively, in the rat hippocampus. Semax-treated animals showed a distinct increase in the number of conditioned avoidance reactions. We suggest that Semax affects cognitive brain functions by modulating the expression and the activation of the hippocampal BDNF/trkB system.” (18)
