    Sammanfattning : The nasopharyngeal tonsil or adenoids is in constant interaction with our environment with every breath we take. This organ, rich in B cells, contains all the immunocompetent cells necessary for an interaction with T cells, exerted through secretion of cytokines and resulting in the production of immunoglobulins and the formation of memory cells.

  3. 2. Clinical and pathogenic aspects of otitis media

    Författare :Anna Granath; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : One study on clinical treatment strategies in otitis media and two studies elucidating immunological events in otitis media in vitro, were conducted and joined in this thesis. First, topical treatment with or without systemic antibiotics against tube associated otorrhea in children with recurrent acute otitis media was evaluated. LÄS MER

  4. 3. A longitudinal study of dentofacial morphology in young children treated for the obstructive sleep apnoea syndrome

    Författare :Lena Zettergren Wijk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The most common cause of OSAS in children is enlarged tonsils and/or adenoids. Consequently, the treatment for OSAS in children with enlarged tonsils and/or adenoids is adeno-/tonsillectomy. The prevalence of OSAS in children is 1-3%, with the peak incidence at the ages 2 to 6 years. LÄS MER

  5. 4. Immune cells in human pharyngeal and palatine tonsils and in the uvula : tissue distribution, cellular composition and functional properties

    Författare :Katarina Olofsson; Marie-Louise Hammarström; Sten Hellström; Britta Rynnel-Dagöö; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The adenoid (pharyngeal tonsil), the palatine tonsils and the uvula are strategically located at the entrance of the upper airodigestive tract. By virtue of their location they are incessantly exposed to inhaled and ingested antigens. LÄS MER

  7. 5. On the role of HMGB1 and IL-1 in tissue barrier defense

    Författare :Cecilia Zetterström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The specialized epithelial surfaces of the lymphoepithelial tissue in the airways and the seminiferous epithelium of the testis are sites of host-environmental interaction at the same time as they serve important physiological functions in gas exchange and reproduction. The host response of a broken epithelial barrier requires rapid mechanisms to control the microflora and to prevent invasion of pathogens. LÄS MER
