Abstract:
:Recent studies have shown that Cerebrolysin can enhance synaptic function and ameliorate synaptodendritic alterations in animal models of neurodegeneration, suggesting a synaptotrophic effect. We hypothesize that Cerebrolysin might exert this effect, in part, by regulating the expression of amyloid precursor protein (APP). We studied the patterns of expression of synaptic proteins during differentiation of human teratocarcinoma cell line NTera 2 (NT2) in the presence or absence of Cerebrolysin. This study showed that the terminally differentiated neurons (NT2N) expressed a wide variety of synaptic markers and that expression of these synaptic-associated proteins coincided with the shift in expression from APP770/751 to APP695. Furthermore, APP immunoreactivity was colocalized with synaptophysin-immunoreactive neuritic varicosities in NT2N neurites, and Cerebrolysin treatment of NT2N cells resulted in an augmented and earlier expression of synaptic-associated proteins. This increased synaptic protein expression coincided with an increase in APP695 over APP770/751. These results support the possibility that synaptotrophic effects of Cerebrolysin might be mediated via regulation of APP expression.
