Several authors have postulated that the ducts of minor salivary glands may provide pathways for the presentation of oral antigens to cells involved in a local immune response. This would imply a retrograde passage of oral antigens into the minor salivary glands. Various sites of the oral mucosa of anaesthesized M. fascicularis monkeys were labelled topically with a multiple tracer consisting of horseradish peroxidase (HRP), ferritin and Indian ink for a continuous period of 4-5 h. Serial cryosectioning of labelled lips and soft palates revealed retrograde passage of this tracer deep into some of the corresponding minor salivary glands. Minor salivary gland ducts can therefore serve as "portal of entry" for oral antigens, at least in the M. fascicularis monkey.
几位作者推测，小唾液腺导管可能为口腔抗原呈递给参与局部免疫反应的细胞提供途径。这意味着口腔抗原逆行进入小唾液腺。对麻醉的猕猴口腔黏膜的不同部位连续4 - 5小时局部标记由辣根过氧化物酶（HRP）、铁蛋白和印度墨水组成的多重示踪剂。对标记的嘴唇和软腭进行连续冰冻切片显示，这种示踪剂逆行深入到一些相应的小唾液腺中。因此，至少在猕猴中，小唾液腺导管可作为口腔抗原的“入口”。
