A Postbiotic Formulation of Lactiplantibacillus plantarum CRL 759 Attenuates Endotoxin Induced Uveitis.

Purpose: To evaluate the anti-inflammatory activity of a cell-free supernatant from Lactiplantibacillus plantarum CRL 759, in phosphate buffer modified according to Sorensen called POF-759.

Methods: The activity of POF-759 administered by means of eye drops was evaluated on animals subcutaneously injected with the lipopolysaccharide animals in which uveitis was induced by a subcutaneous injection of lipopolysaccharide (EIU). Clinical signs of ocular inflammation, cytokines and proteins were examined in the aqueous humor. Additionally, cellular infiltration was evaluated by histopathological analysis.

Results: The new postbiotic administered locally decreases signs of ocular damage, the number of infiltrating cells in the anterior and posterior chambers, the proinflammatory mediators and the proteins in the aqueous humor on mice with EIU.

Conclusions: Our results provide an impetus to relieve ocular inflammation and to identify and develop preventive and therapeutic approaches, to avoid deterioration and to maintain healthy eyes on inflammatory processes.
