Outline of Final Research Achievements |
In this study, we investigated the role of pneumococcal cell surface protein, PfbA, in the evasion from host innate immunity. Bioinformatic analysis showed that PfbA is a highly and specifically conserved protein in Streptococcus pneumoniae strains. In addition, our experimental results indicated that PfbA contributes to bacterial resistance to neutrophil killing via inhibiting its phagocytosis.
