Proposed model of how dead L. paracasei D3-5 and its cell wall-derived LTA ameliorate leaky gut and inflammation, and promotes healthy aging. Mechanistically, D3-5-derived LTA activates TLR2/p38-MAPK signaling resulting in increased mucin production to suppress leaky gut and inhibit NF-κB to reduce inflammation
