Effects of recombinant human epidermal growth factor (hEGF) on short-term potentiation (STP) of evoked potential were investigated in Schaffer/commissural-CA1 pyramidal cell synapses of rat hippocampal slices. Perfusion of hEGF (6-60 ng/ml) significantly enhanced the STP induced by shorter tetanus (11 impulses at 100 Hz) in a concentration-dependent manner and the effect resulted in generation of long-term potentiation (LTP). The results suggest that hEGF can activate the mechanisms related to induction of LTP.
在大鼠海马脑片的Schaffer/联合-CA1锥体细胞突触中,研究了重组人表皮生长因子(hEGF)对诱发电位短期增强(STP)的影响。灌注hEGF(6 - 60 ng/ml)以浓度依赖的方式显著增强了由较短强直刺激(100 Hz下11个脉冲)诱导的STP,并且该效应导致了长时程增强(LTP)的产生。结果表明,hEGF可以激活与LTP诱导相关的机制。
