Lipid Binding Protein Complexes in Organ Preservation Solutions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current organ preservation methods, such as static cold storage, are inadequate in preventing ischemia/reperfusion injury during organ transplantation, leading to suboptimal graft outcomes and limited availability of suitable donor organs.
Innovation Solution
The use of lipid binding protein-based complexes, such as HDL mimetic drug CER-001, in organ preservation solutions to reduce inflammation, oxidative stress, and endothelial dysfunction, thereby protecting grafts during storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static cold storage is used for organ preservation, then storage simplicity is maintained, but ischemia/reperfusion injury increases leading to poorer graft outcomes
Solution Approach 1:
The patent modifies the chemical composition parameters of the preservation solution by incorporating lipid binding proteins (such as HDL, ApoA-I) and specific phospholipids (sphingomyelin, phosphatidylcholine, phosphatidylserine) in defined ratios. These parameter changes enable the solution to actively bind and neutralize harmful lipids and inflammatory mediators, thereby reducing ischemia/reperfusion injury while maintaining operational simplicity
Solution Approach 2:
The preservation solution employs a composite formulation combining multiple lipid binding proteins, various phospholipid types, antioxidants, and anti-inflammatory agents. This composite approach creates synergistic effects where different components work together to provide comprehensive protection against cellular injury, oxidative stress, and inflammation during storage and reperfusion
2Quantity of substance
If marginal organs from ECD or DCD donors are transplanted, then donor pool availability increases, but graft survival and function deteriorate
Solution Approach 1:
The patent applies preliminary protective action by exposing marginal organs to the lipid binding protein-containing preservation solution before transplantation. This pre-treatment allows the solution to bind harmful lipids, reduce oxidative stress, and prevent inflammatory activation during the storage period, thereby improving graft viability and reducing delayed graft function when these organs are subsequently transplanted
3Reliability
If machine perfusion is used instead of static cold storage, then organ function is improved, but device complexity increases
Solution Approach 1:
The lipid binding protein-containing preservation solution acts as an intermediary substance that can be used in both static cold storage and machine perfusion systems. This intermediary approach allows the beneficial effects of lipid binding proteins to be achieved without requiring complex perfusion machinery, thereby maintaining operational simplicity while improving organ outcomes

Function Achieved in This Case
The incorporation of lipid binding protein-based complexes in organ preservation solutions effectively decreases the risk of delayed graft function and acute rejection, improving renal function and organ viability, and potentially expanding the donor pool by enhancing the quality of marginal organs.
