Overview

Limosilactobacillus fermentum SLAM216 extracellular vesicles (LF216EV) is an experimental, probiotic-derived biologic. It consists of nano-sized extracellular vesicles from the Limosilactobacillus fermentum SLAM 216 bacterial strain, which contain a complex mixture of proteins, enzymes, nucleic acids, and lipids (including linoleic, oleic, palmitic, sebacic, and stearic acids). [1] LF216EV functions by modulating the gut microbiota and serotonin metabolism pathways. It has been shown to target immune regulatory genes (such as TSLP, TNFα, IL-6, IL-1β) in cell models. [2] This mechanism, operating through the gut-skin axis, leads to increased serotonin synthesis and has shown potential in preclinical mouse models for treating atopic dermatitis and associated psychiatric symptoms like anxiety and depression. [1, 2] It is currently considered an academic research compound with developers at institutions like Seoul National University and the Korea Food Research Institute. [2, 5]
