Screening and Construction of Probiotic Strains with Enhanced Protective Properties against Intestinal Disorders
2011
Within the scope of the DEPROHEALTH project, a range of wild-type strains of Lactobacillus were analysed for their ability to interact with the host immune system. While the studied isolates interacted in a strain-specific way with immune cells, they seemed to have little and non-discriminative effect on epithelial cells. However, they were shown to facilitate the cross-talk between intestinal and immune cells. Studies conducted in mouse colitis models confirmed that specific strains possess higher intrinsic anti-inflammatory properties. Two of these were further engineered to produce murine IL10 and are presently being evaluated for their protective effect in a TNBS colitis model. Cell wal…
Anti-inflammatory Lactobacillus rhamnosus CNCM I-3690 strain protects against oxidative stress and increases lifespan in Caenorhabditis elegans.
2012
International audience; Numerous studies have shown that resistance to oxidative stress is crucial to stay healthy and to reduce the adverse effects of aging. Accordingly, nutritional interventions using antioxidant food-grade compounds or food products are currently an interesting option to help improve health and quality of life in the elderly. Live lactic acid bacteria (LAB) administered in food, such as probiotics, may be good antioxidant candidates. Nevertheless, information about LAB-induced oxidative stress protection is scarce. To identify and characterize new potential antioxidant probiotic strains, we have developed a new functional screening method using the nematode Caenorhabdit…
