Abstract: In the present invention, lactic acid bacteria produce soluble factors (such as peptides or proteins) that block inflammatory responses in a mechanism that depends on G proteins and is post-transcriptional to effectively block protein production or secretion by cells.

Abstract: Strains of Lactobacillus that have been selected for their capability of reducing the number of Streptococcus mutans in the mouth of mammals through inhibiting activity in combination with good binding to the oral mucins and dental plaque, thereby preventing, reducing or treating dental caries, and products derived from said strains, including agents for treatment or prophylaxis of caries for administration to humans.

Abstract: Strains of Lactobacillus which have been selected for their capability of reducing gastrointestinal inflammation, such as that due to Helicobacter pylori, and products derived from these strains, including agents for treatment or prophylaxis of inflammation associated with Helicobacter pylori for administration to humans and include conditioned media in which the selected strains have grown and protein-containing extracts of the conditioned media.
