PVRL4 (nectin-4) was recently identified as the epithelial receptor for members of the Morbillivirus genus, including measles virus, canine distemper virus and peste des petits ruminants virus. Here, we describe the role of PVRL4 in morbillivirus pathogenesis and its promising use in cancer therapies. This discovery establishes a new paradigm for the spread of virus from lymphocytes to airway e...

The pathogenesis of two rodent-adapted strains of measles virus was studied in 1- to 2-day-old suckling and 4-week-old weanling BALB/c mice. Both the mouse-adapted Edmonston (MAEd) strain and the hamster-neurotropic (HNT) strain caused necrotizing giant-cell encephalitis with a 90 to 100% mortality after intracerebral inoculation into suckling mice. After intracerebral inoculation into weanling...

The sequences of a region of the nucleocapsid protein gene, between nucleotides 1231 and 1686, encoding the C-terminal 151 amino acid residues of the nucleocapsid protein have been determined for 16 strains of measles virus. Analysis of this region showed that it is highly divergent (up to 7.2% divergence in the nucleotide sequence and 10.6% divergence in the amino acid sequence between most di...

The ability of a virus to alter an expected immune response first received recognition over three-quarters of a century ago. At that time, Clements von Pirquet (1) observed that children who were tuberculin positive before contracting acute measles virus infection failed to mount specific skin responses to tuberculin during that virus infection. Later reports confirmed von Pirquet's observation...

BACKGROUND B cells and humoral immune responses play an important role in the pathogenesis and diagnosis of multiple sclerosis (MS). A characteristic finding in patients with MS is a polyspecific intrathecal B cell response against neurotropic viruses, specifically against measles virus, rubella virus, and varicella zoster virus, also known as an MRZ reaction (MRZR). Here, we correlated from th...

The aetiology of Crohn’s disease is unknown. Any hypothesis must take into account the continuing increase in incidence in some countries, including the UK. The increase aVects the population from early teens, and specific comprehensive epidemiological studies in children and adolescents show a continuing rise in the rate of age and sex standardised incidence in Scotland. This suggests an envir...

We examined the relationship between a measles virus isolate from a child with Kawasaki disease and two contemporaneous wild-type isolates from children with 'classical' measles and the Schwarz vaccine strain. Sequence analysis of 3118 bp from the nucleoprotein, matrix, fusion and haemagglutinin genes of each virus revealed that the isolate from the child with Kawasaki disease was not related t...

In 2005, the World Health Organization (WHO) Regional Committee for the Western Pacific Region (WPR) resolved that WPR should aim to eliminate measles by 2012. The recommended measles elimination strategies in WPR include 1) achieving and maintaining high (≥95%) coverage with 2 doses of measles-containing vaccine (MCV) through routine immunization services and by implementing supplementary immu...

BACKGROUND A link between measles virus and Crohn's disease (CD) has been postulated. We assessed through bioinformatic and immunological approaches whether measles is implicated in CD induction, through molecular mimicry. METHODS The BLAST2p program was used to identify amino acid sequence similarities between five measles virus and 56 intestinal proteins. Antibody responses to measles/human...

The persistence of measles virus in selected areas of the brains of four patients with subacute sclerosing panencephalitis (SSPE) was characterized by immunohistological and biochemical techniques. The five measles virus structural proteins were never simultaneously detectable in any of the brain sections. Nucleocapsid proteins and phosphoproteins were found in every diseased brain area, wherea...
