Peyer's patches (PP) of rats were studied with immunocytochemical, enzyme cytochemical, and electron microscopic techniques. Special attention was paid to the non-lymphoid antigen-trapping cells. Follicular dendritic cells, morphologically comparable to those present in spleen and lymph nodes, were found in the germinal centers of PP. Ia-positive cells with the morphological characteristics of interdigitating cells were seen in the interfollicular area. Thus, both types of antigen-presenting cells, characteristic for B- and T-cell areas, respectively, were present in PP.
采用免疫细胞化学、酶细胞化学及电子显微镜技术对大鼠的派尔集合淋巴结（PP）进行了研究。特别关注了非淋巴细胞性抗原捕获细胞。在PP的生发中心发现了形态上与脾脏和淋巴结中的滤泡树突状细胞相似的细胞。在滤泡间区域可见具有指状突细胞形态特征的Ia阳性细胞。因此，PP中存在分别为B细胞区和T细胞区所特有的两种抗原呈递细胞。
