In addition to the rash, fever, and upper respiratory tract congestion that are the hallmarks of acute measles virus (MV) infection, invasion of the central nervous system (CNS) can occur, establishing a persistent infection primarily in neurons. The recent identification of the human membrane glycoprotein, CD46, as the MV receptor allowed for the establishment of transgenic mice in which the C...
Edmonston vaccine strains of measles virus (MV) have shown significant antitumor activity in preclinical models of ovarian cancer. We engineered MV to express the marker peptide carcinoembryonic antigen (MV-CEA virus) to also permit real-time monitoring of viral gene expression in tumors in the clinical setting. Patients with Taxol and platinum-refractory recurrent ovarian cancer and normal CEA...
Sequence analysis was performed on 20 measles virus (MV) isolates from South Africa, five of which were obtained between 1986 and 1989 and 15 isolates collected during the 1994/95 measles season. A 590 bp fragment of the carboxyl terminus of the nucleocapsid (N) was amplified by PCR and subjected to sequence and phylogenetic analysis. Comparison of the South African MV strains with those previo...
Paramyxoviruses comprise several major human pathogens. Although a live-attenuated vaccine protects against measles virus (MV), a member of the paramyxovirus family, the virus remains a principal cause of worldwide mortality and accounts for approximately 21 million cases and 300,000 to 400,000 deaths annually. The development of novel antivirals that allow improved case management of severe me...
Measles virus (MV) is one of the most infectious pathogens known. Despite the existence of a vaccine, over 500,000 deaths/year result from MV or associated complications. Anti-measles compounds could conceivably reverse these statistics. Previously, we described a homology model of the MV fusion protein trimer and a putative binding site near the head-neck region. The resulting model permitted ...
By reverse transcription-PCR, measles virus (MV) mRNA was detected in the brain, kidney, spleen, liver, and lung tissues obtained from 23 (45.1%) of 51 autopsy subjects, with the detection rates of each tissue ranging from 8 to 20%. Sequence analysis revealed frequent mutations in the corresponding viral protein. These results suggest that MV mutants commonly persist in apparently healthy indiv...
Rescue of negative-stranded RNA viruses from full-length genomic cDNA clones is an essential technology for genetic analysis of this class of viruses. Using this technology in our studies of measles virus (MV), we found that the efficiency of the measles virus rescue procedure (F. Radecke et al., EMBO J. 14:5773-5784, 1995) could be improved by modifying the procedure in two ways. First, we fou...
Acute measles (for review see: Grif®n and Bellini, 1996) can be accompanied by early or late central nervous system (CNS) complications. These include the acute postinfectious measles encephalitis (APME), which develops 2 ± 4 weeks after infection, or as late complications, the measles inclusion body encephalitis (MIBE) in immunocompromised patients, and the subacute sclerosing panencephalitis ...
Nucleotide sequence of the genes encoding the matrix protein of two wild-type measles virus strains.
The nucleotide sequences of the matrix protein (M) genes of two wild-type measles virus (MV) isolates (JM and CM) have been determined and shown to differ in 56 positions; 31 of these differences are located in the non-coding region and 25 in the coding region of the gene. Most (80%) of the mutations in the coding region are changes to the third base of a codon. A maximum parsimony analysis of ...
It has been shown previously that measles virus (MV) can be successfully used to express foreign proteins (M. Singh and M. A. Billeter, J. Gen. Virol. 80:101-106, 1998). To develop an inexpensive MV-based vaccine, we generated recombinant MVs that produce structural proteins of hepatitis B virus (HBV). A recombinant virus that expressed the HBV small surface antigen (HBsAg) was analyzed in term...
