Outer membrane proteins from respiratory pathogens - implications for pathogenesis and vaccine development
Principal investigator; Riesbeck, Kristian, Professor, MD/PhD
Respiratory tract infections are a common health problem and cause 2-3 millions medical care visits per year only in Sweden. The three most frequently isolated bacteria in such infections are Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis. Today a vaccine against pneumococci is included in the general vaccination program for children in Sweden. Our research is focused on H. influenzae and M. catarrhalis and their interactions with the human host. We are particularly interested in identifying adherence molecules, both on the bacterial side and human counterpart, used to initiate the infection or colonization. In addition, we are studying the mechanisms by which the bacteria interact with, avoid or induce the human immune system in the respiratory tract. Several by us characterized outer membrane proteins of these pathogens are considered promising vaccine candidates. The main beneficiaries for a future vaccine are expected to be the very young and COPD patients since these two groups are the ones with the highest risk of respiratory infections, particularly by H. influenzae.
