Precision Medicine in Surgery: Immunomodulation and Cellular Regeneration Strategies for Immunologic and Surgical Diseases.

OBJECTIVE

This article presents a methodological framework for studying the effects of lacritin peptide on β-cell proliferation, islet viability, and immune modulation using a combination of in vitro and in vivo models.

BACKGROUND

Immunologic and inflammatory diseases, including autoimmune disorders and organ-specific injuries, present significant therapeutic challenges owing to persistent inflammation and limited tissue regeneration. Therapies that combine immunomodulation and cellular regeneration may address this need in conditions such as Crohn disease, heart failure, pulmonary fibrosis, chronic kidney disease, and neurological injuries. 'Lacritin' displays both immunomodulatory and regenerative activities, and is significantly deficient in T1 diabetics.

METHODS

Pancreatic islet in vitro testing, mass cytometry, imaging mass cytometry, and single-cell RNA sequencing to assess immune cell interactions. In addition, in vivo transplantation of lacritin peptide-treated islets into diabetic mouse recipients and immunologic studies in the nonobese diabetic mouse model support the preclinical evaluation of lacritin in its therapeutic potential.

RESULTS

In this article, we discuss the increasing need for precision medicine for immunologic and surgical diseases. Within our experimental framework, we generate valuable insights into immune cell behavior, tissue architecture, and regenerative dynamics with lacritin intervention at the preclinical stage.

CONCLUSIONS

Through this study, we aimed to facilitate further investigations into future precision medicine strategies, including lacritin peptide and other peptide-based therapeutics for immunologic and surgical diseases.
