Structural and functional analysis of the S-layer protein crystallisation domain of Lactobacillus acidophilus ATCC 4356 : evidence for protein : protein interaction of two subdomains

The structure of the crystallisation domain, SAN, of the S A-protein of Lactobacillus acidophilus ATCC 4356 was analysed by insertion and deletion mutagenesis, and by proteolytic treatment. Mutant S A-protein synthesised in Escherichia coli with 7-13 amino acid insertions near the N terminus or within regions of sequence variation in SAN (amino...

Lactobacilli as vehicles for targeting antigens to mucosal tissues by surface exposition of foreign antigens

Engineering the microflora to vaccinate the mucosa: Serum immunoglobulin G responses and activated draining cervical lymph nodes following mucosal application of tetanus toxin fragment C-expressing lactobacilli

Instruments for oral disease-intervention strategies: Recombinant Lactobacillus casei expressing tetanus toxin fragment C for vaccination or myelin proteins for oral tolerance induction in multiple sclerosis

Lactobacillus strains possess properties that make them attractive candidates as vehicles for oral administration of therapeutics. In this report we describe the construction and analysis of recombinant Lactobacillus casei applicable in oral vaccination against an infectious disease (tetanus) and in oral tolerance induction for intervention in...
