Research Abstract

最近我々は、ガストリン放出ペプチド(GRP)の発現が雌に比べ、雄ラットの腰髄に有意に高いことを新規に見いだした(Sakamoto et al., Nature Neuroscience2008)。本研究では、心的外傷後ストレス障害(PTSD)に伴う心因性勃起障害(ED)の中枢性病態生理を明らかにする目的で、PTSDモデルラットとして学際的に認められている短期持続ストレス(single-prolonged stress)を用いて、腰髄GRP系の解析を行った。その結果、過剰なストレス負荷が腰髄GRP系を破綻させることにより、雄性性機能低下を惹起することが示唆された。
