Purpose: The study investigated the effects of hyper-sugar situation and the antimicrobial peptide (lipid-carrying protein-2, LCN2) treatment to the UPEC infection in bladder cells, and identified the induced-inflammation and its regulatory pathways.

Materials and Methods: We used in vitro GFP-UPEC infected model in bladder cell line, combining with the blocking JAK/STAT pathway experiments to assess the interaction of LCN2 and glucose influencing the UPEC infection and inflammation in bladder cells.

Results: The present study showed the suppressive effects of LCN2 on UPEC infection and induced inflammation in bladder epithelial cells in a high-glucose environment.

Conclusions: The results will help clarify the correlation between AMP production and UTI, identify the relationship between urinary tract infection and diabetes in UTI patients, and develop novel diagnostics or possible treatments targeting AMP. The results may contribute to the treatment and prognosis study of subsequent urinary tract infections in diabetic patients.
