Abstract
The degree of HLA compatibility between a patient and donor has formed the basis of donor selection since the development of allogeneic hematopoietic cell transplantation over 50 years ago and has advanced understanding of the basic immunobiology of HLA. New evidence supports a role for germline variation in the patient and the donor that do not require HLA matching for their effects to have clinical consequences. The discovery of novel non-coding polymorphisms, structural features of HLA molecules, and expression provide new models for donor selection and inspire the development of tools for clinical translation. Pairwise effects of HLA ligand/donor NK receptors may play an important role in transplant outcomes and showcase the value of understanding the role played by each constituent of the NK pathway in modulating donor responses to target antigens.
期刊介绍：
Best Practice & Research Clinical Haematology publishes review articles integrating the results from the latest original research articles into practical, evidence-based review articles. These articles seek to address the key clinical issues of diagnosis, treatment and patient management. Each issue follows a problem-orientated approach which focuses on the key questions to be addressed, clearly defining what is known and not known, covering the spectrum of clinical and laboratory haematological practice and research. Although most reviews are invited, the Editor welcomes suggestions from potential authors.
