The stability of whole bacteriophage lambda particles, used as a DNA vaccine delivery system has been examined. Phage were found to be highly stable under normal storage conditions. In liquid suspension, no decrease in titre was observed over a 6-month period at 4 and -70 degrees C, and phage stability was unaffected by freeze/thawing. The measured half(More)
Mice and rabbits have been vaccinated with whole bacteriophage lambda particles containing a DNA vaccine expression cassette under the control of the CMV promoter (enhanced green fluorescent protein [lambda-EGFP] or hepatitis B surface antigen [lambda-HBsAg]). Mice were vaccinated twice intramuscularly (i.m.) with 5x10(9) of lambda-EGFP phage (containing(More)
A bacteriophage lambda DNA vaccine expressing the small surface antigen (HBsAg) of hepatitis B was compared with Engerix B, a commercially available vaccine based on the homologous recombinant protein (r-HBsAg). Rabbits (five per group) were vaccinated intramuscularly at weeks 0, 5 and 10. Antibody responses against r-HBsAg were measured by indirect(More)
A new strategy for rapidly selecting and testing genetic vaccines has been developed, in which a whole genome library is cloned into a bacteriophage lambda ZAP Express vector which contains both prokaryotic (P(lac)) and eukaryotic (P(CMV)) promoters upstream of the insertion site. The phage library is plated on Escherichia coli cells, immunoblotted, and(More)
Fukutin and fukutin-related protein (FKRP) are involved in the glycosylation of α-dystroglycan, a key receptor for basement membrane proteins. Aberrant α-dystroglycan glycosylation leads to a broad spectrum of disorders, ranging from limb girdle muscular dystrophy to Walker-Warburg syndrome. This is the first study investigating a role of fukutin and(More)
The small signalling adaptor protein Dok-7 has recently been reported as an essential protein of the neuromuscular junction (NMJ). Mutations resulting in partial loss of Dok-7 activity cause a distinct limb-girdle subtype of the inherited NMJ disorder congenital myasthenic syndromes (CMSs), whereas complete loss of Dok-7 results in a lethal phenotype in(More)
