Neuroprotective Effect of Tauroursodeoxycholic Acid (TUDCA) on In Vitro and In Vivo Models of Retinal Disorders: A Systematic Review

Conclusion: This systematic review demonstrated that TUDCA has neuroprotective effect on in vivo and in vitro models of retinal disorders, reinforcing the currently available evidence that TUDCA could be a promising therapeutic agent in retinal diseases treatment. However, well designed clinical trials are necessary to appraise the efficacy of TUDCA in clinical setting.

TUDCA and 4-PBA in Preclinical Models of Beta-Cell Secretory Failure: A Systematic Review and Bayesian Meta-Analysis

Conclusion: Because no source report documents blinding of outcome assessment, the pooled estimate should be read as an upper bound. In conclusion, TUDCA and 4-PBA act as chemical chaperones that alleviate ER stress and may prevent terminal UPR activation and preserve the beta-cell exocytotic machinery, positioning them as candidate disease-modifying agents that merit confirmatory clinical evaluation.

From dried bear bile to molecular investigation: A systematic review of the effect of bile acids on cell apoptosis, oxidative stress and inflammation in the brain, across pre-clinical models of neurological, neurodegenerative and neuropsychiatric disorders

Conclusion: In addition, findings suggest that all the three bile acids would be equally beneficial in models of Huntington's disease, whereas UDCA and TUDCA would be more beneficial in models of Parkinson's disease and Alzheimer's disease, while GUDCA in models of bilirubin encephalopathy and TUDCA in models of depression. Overall, this review confirms the therapeutic potential of UDCA, GUDCA and TUDCA in neurological, neurodegenerative and neuropsychiatric disorders, proposing bile acids as potential alternative therapeutic approaches for patients suffering from these disorders.

Retinal changes and treatment in ocular alkali burn: a systematic review of animal models and case reports summary

Conclusion: Retinal injury is a significant but under-recognized consequence of severe OAB. Preclinical studies demonstrate that treatments which offer neuroprotective and anti-inflammatory properties mitigate retinal damage in OAB models. However, clinical evidence remains limited. These findings underscore the importance of early retinal evaluation in OAB and highlight the need for future clinical studies to validate and implement effective treatment strategies.
