On the future of HLA

Area of Science:

• Immunology
• Genetics
• Transplantation Science

Background:

• The human leucocyte antigen (HLA) complex is central to basic and clinical immunology.
• Understanding HLA's immunobiological function has driven significant advancements in the field.
• Classical HLA class I and II genes are key players in immune responses and disease susceptibility.

Purpose of the Study:

• To discuss critical future challenges and opportunities in HLA research.
• To highlight the evolving role of HLA in transplantation, autoimmune diseases, and other areas.
• To emphasize the need for a greater focus on the functional immunogenetics of HLA.

Main Methods:

• This is an opinion article, synthesizing current knowledge and expert perspectives.
• It focuses on reviewing the implications of HLA research in various medical and scientific domains.
• No novel experimental methods are presented; it's a forward-looking perspective piece.

Main Results:

• HLA matching remains crucial for organ and hematopoietic stem cell transplantation success.
• HLA genes are strongly associated with the etiology and pathogenesis of autoimmune diseases.
• The role of HLA is expanding into pharmacogenomics, vaccinations, and anthropology.

Conclusions:

• Predicting and preventing autoimmune diseases presents a major future challenge for HLA research.
• Increased focus on functional immunogenetics is necessary to address emerging challenges and opportunities.
• The HLA field is poised for continued growth, with significant implications for human health and evolution.
