Regulation of induced colonic inflammation by Lactobacillus acidophilus deficient in lipoteichoic acid.

Imbalance in the regulatory immune mechanisms that control intestinal cellular and bacterial homeostasis may lead to induction of the detrimental inflammatory signals characterized in humans as inflammatory bowel disease. Induction of proinflammatory cytokines (i.e.

Targeted expression of anthrax protective antigen by Lactobacillus gasseri as an anthrax vaccine.

Aim: Induction of protective immunity against pathogenic microbes, including Bacillus anthracis, requires efficient vaccines that potentiate antibody avidity and increase T-cell longevity. We recently reported that the delivery of targeted B. anthracis protective antigen (PA) genetically fused to a DC-binding peptide (DCpep) by Lactobacillus acidophilus induced mucosal and systemic immunity against B.
