神经肽Y及其Y1受体阳性细胞在鸭腔上囊中的分布及发育变化(英文)

神经肽Y及其Y1受体在神经-免疫-网路中发挥着重要作用。二者在许多脊椎动物胸腺和脾脏中的表达已有研究,但它们在腔上囊中的表达及发育变化特征还未见报道。本试验应用免疫组化技术研究神经肽Y及其Y1受体阳性细胞在鸭腔上囊胚胎及胚后发育中的分布及变化特征。结果显示,在鸭腔上囊中神经肽Y及其Y1受体分别最早表达于26和22d胚龄。神经肽Y阳性细胞分布于黏膜上皮、滤泡、肌层和小动脉平滑肌。Y1受体阳性细胞分布于黏膜上皮、滤泡淋巴细胞。各部位神经肽Y及其Y1受体阳性细胞数量表现出明显增龄变化特征。结果说明鸭腔上囊中存在神经肽Y及其Y1受体,二者可能存在的相互作用主要表现在胚后发育阶段,这与B淋巴细胞的发育与分化以及腔上囊的退化密切相关。

Distribution and developmental changes in Neuropeptide-Y and Y1 receptor-immunoreactivity cells in the duck bursa of Fabricius

Playing significant roles within the neuroimmune crosstalk,neuropeptide-Y(NPY) and its Y1 receptor(Y1) have been found in the thymus and spleen of many vertebrates,but their distribution and developmental changes have not been defined in the bursa of Fabricius.In this study,the distribution and developmental changes in NPY and Y1 immunoreactivity(-ir) cells in the duck bursa of Fabricius during the embryonic and post embryonic development were investigated using immunohistochemistry associated with morphome...
