Complement in renal transplantation: The road to translation

Area of Science:

• Immunology
• Nephrology
• Transplantation Medicine

Background:

• Renal transplantation is the primary treatment for end-stage renal disease.
• The complement system is integral to the success and complications of kidney transplants.
• Understanding complement's role is crucial for improving patient outcomes.

Purpose of the Study:

• To review the multifaceted role of the complement system throughout renal transplantation phases.
• To analyze complement's contribution to transplant injury and rejection pathogenesis.
• To evaluate current and emerging complement-targeted therapeutic strategies.

Main Methods:

• Comprehensive literature review of complement's involvement in renal transplantation.
• Examination of local and systemic complement production and activation pathways.
• Analysis of clinical trials investigating complement inhibition therapies.

Main Results:

• Complement activation contributes significantly to renal transplant injury and rejection.
• Specific complement pathways are implicated in donor, preservation, reperfusion, and rejection phases.
• Therapeutic strategies targeting complement are under active clinical investigation.

Conclusions:

• Complement inhibition is a promising therapeutic avenue for renal transplantation.
• Targeted complement therapeutics are expected to be clinically implemented soon.
• These therapies aim to enhance renal graft function and long-term survival.
