Resumo

MINIGGIO, HD. Biological significance of palatine tonsillar epithelium: microstructure and disease. S. Afr. dent. j. [online]. 2016, vol.71, n.10, pp.496-499. ISSN 0375-1562.

The epithelial microstructural configuration of the paired palatine tonsils is adapted to optimize lympho-epithelial symbiosis at the first point of contact with an antigen introduced to the pharynx through breathing or swallowing. The loosely arranged reticulated nature of the epithelium of the tonsillar crypt and vesicular transcytosis of live bacteria and viruses across receptor cells contribute to the early pathogenesis of specific neoplastic- and infective diseases which are discussed in the manuscript.

Palavras-chave : tonsillar-epithelium; tonsillar-crypt; immunity; M-cells; oncogenesis; epithelial-lymphoid symbiosis; tonsillar-disease.
