Abstract:
:Using fluorescein-labelled antibodies against gamma, mu and alpha chains, Ig-containing cells in palatine tonsils were studied in 120 patients. The aim of this study was to determine the most frequently repeated typical findings as regards the numbers and localisation of these cells in tonsils and to confront the data obtained with the concept that tonsils are a component of the local immunity system. The preponderance of IgG over IgA cells was confirmed, both cell types being preferentially localized in extrafollicular tissue whereas IgM was mostly found in germinal centres. Together with progressing tonsillar atrophia, the frequency of positive findings of IgM decreased, whereas the numbers of IgG and IgA cells were proportional to the amount of remaining lymphoid tissue. IgA cells were not preponderant in tonsils and their localization in the surface layer of epithelium was rather exceptional, SC antigen could not be demonstrated unequivocally and the morphological picture in germinal centres was characteristic for IgM production rather for IgA. Thus the palatine tonsils according to the content and distribution of immunocytes, correspond to the lymph node rather than to an organ involved significantly in the local antibody formation.
