Role of HLA molecular mismatch in clinical practice

Hum Immunol. 2021 Dec 6:S0198-8859(21)00258-5. doi: 10.1016/j.humimm.2021.11.005. Online ahead of print.ABSTRACTTo date, traditional pre-transplant risk factors have failed to provide accurate risk stratification in transplantation. As a result, the practice of precision medicine remains elusive, resulting in a one-size-fits-all therapeutic approach for most patients. However, recent advancements in the understanding of HLA molecules at the molecular level have revitalized interest in HLA mismatch assessment. This review discusses HLA molecular mismatch as a potential prognostic and predictive biomarker available at the time of transplantation and answers some of the common questions and critiques of this approach. We highlight the retrospective data that supports single molecule risk categorization and explore the next steps required to evaluate its potential in clinical practice.PMID:34887099 | DOI:10.1016/j.humimm.2021.11.005
