Haemophilus influenzae (Hi), a commensal of the human respiratory mucosa, is an important cause of localized and systemic infections. We show that distinct strains belonging to typable (THi) and non-typable (NTHi) H. influenzae target human carcinoembryonic antigens (the membrane associated CEA family of cell adhesion molecules, are now termed CEACAMs).

The pili of Neisseria meningitidis are a key virulence factor, being major adhesins of this capsulate organism that contribute to specificity for the human host. Recently it has been reported that meningococcal pili are post-translationally modified by the addition of an O-linked trisaccharide, Gal (beta1-4) Gal (alpha1-3)(More)
The human pathogens Neisseria meningitidis and Neisseria gonorrhoeae express a family of variable outer membrane opacity-associated (Opa) proteins that recognize multiple human cell surface receptors. Most Opa proteins target the highly conserved N-terminal domain of the CD66 family of adhesion molecules, although a few also interact with heparan sulphate(More)
Haemophilus influenzae, a commensal of the human respiratory mucosa, is an important cause of localized and systemic infections. We have recently shown that numerous strains of capsulate (typeable) and acapsulate (non-typeable) H. influenzae target the carcinoembryonic antigen (CEA) family of cell adhesion molecules (CEACAMs). Moreover, the ligands appeared(More)
A predisposing gene for breast and ovarian cancer has recently been mapped to chromosome 17q12–21. If this gene is a tumour suppressor gene, allele losses would be expected in the tumours of affected family members and the losses should affect the wild–type chromosome, reflecting the need for inactivation of the wild–type allele at the predisposing locus.(More)
Neurofibromatosis 2 (NF2) is caused by inactivating mutations of the NF2 tumor suppressor gene. Somatic NF2 mutations also occur in a high proportion of human primary malignant mesotheliomas. We report an elderly man with NF2, malignant mesothelioma, and a constitutional NF2 missense mutation. The long latent period for mesothelioma in this patient (61(More)
We provide experimental evidence of a replication enhancer element (REE) within the capsid gene of tick-borne encephalitis virus (TBEV, genus Flavivirus). Thermodynamic and phylogenetic analyses predicted that the REE folds as a long stable stem-loop (designated SL6), conserved among all tick-borne flaviviruses (TBFV). Homologous sequences and potential(More)
