LYZ and Anxiety: Supplementation with Lactobacillus plantarum diminished toxic effects due to triclosan exposure, restored levels of triglycerides and total cholesterol, decreased number of CD4 T cells in the lamina propria of duodenal mucosa, and decrease in expression of intestinal pro-inflammatory cytokines (NF-κB, and lysozyme). Supplementation with Lactobacillus plantarum also decreased anxiety like behavior and improved learning/memory following chronic Triclosan exposure.
