Direct ex-vivo evaluation of pneumococcal specific T-cells in healthy adults.
Streptococcus pneumoniae is an encapsulated bacterium that causes significant global morbidity and mortality. The nasopharynxes of children are believed to be the natural reservoir of pneumococcus and by adulthood nasopharyngeal carriage is infrequent; such infrequency may be due to demonstrable pneumococcal specific T and B-cell responses. HLA Class 2 tetrameric complexes have been used to characterise antigen specific T-cell responses in a variety of models of infection. We therefore sought...Expand abstract
