Innate Immune Memory Responses in Organ Transplantation.

Area of Science:

• Immunology
• Transplantation Science
• Innate Immunity

Background:

• Innate immunity plays a key role in organ transplant rejection and cardiovascular issues.
• Innate immune memory, particularly trained immunity, influences graft survival.
• Factors like hypercholesterolemia and hyperglycemia can induce trained immunity.

Purpose of the Study:

• To review current knowledge on innate immune memory in solid organ transplantation.
• To discuss trained immunity and innate allogeneic memory.
• To highlight their influence on graft outcomes.

Main Methods:

• Review of experimental and clinical studies.
• Analysis of epigenetic and metabolic reprogramming in trained immunity.
• Examination of innate immune cell recognition of non-self antigens.

Main Results:

• Trained immunity involves epigenetic and metabolic changes in innate immune cells, altering inflammatory responses.
• Innate allogeneic memory demonstrates the capacity of innate immune cells to mount donor-specific responses.
• Both forms of innate immune memory are linked to graft survival and complications.

Conclusions:

• Innate immune memory significantly affects solid organ transplantation outcomes.
• Further research into trained immunity and innate allogeneic memory is needed.
• Targeting innate immune memory may offer therapeutic strategies for transplantation.
