  10. C5aR and C5L2 may have roles in adiposity in women PMID: 24523571
  11. A novel polymorphism (901G > a) of C5L2 gene is associated with coronary artery disease in Chinese Han and Uyghur population. PMID: 24073849
  12. our study indicates that 698C>T polymorphism of C5L2 gene is associated with the T2DM in individuals of Saudi population which was found to be similar with other studies. PMID: 24078164
  13. C5L2 may be implicated in the pro-inflammatory role in C5a-primed neutrophils for ANCA-induced activation. PMID: 23785491
  14. C5L2 receptors are abundant in neurofibrillary tangles in Alzheimer's disease brain compared to controls. PMID: 23394121
  15. The results suggest that insulin sensitivity may be permissive for coupling of C5L2 levels to lipid storage and utilization. PMID: 23460866
  16. C5L2 has been recently demonstrated to physically interact with both C5aR and beta-arrestin to negatively regulate C5aR signaling toward an anti-inflammatory manner PMID: 23239822
  17. C5L2 was expressed in the kidney and localized to the distal convoluted tubule and connecting tubule. PMID: 22960554
  18. genetic association studies in the Chinese Han population: Data suggest that an SNP in C5L2 (C698T) is associated with type 2 diabetes mellitus; 698CT heterozygotes exhibited increased serum triglyceride levels. PMID: 22180093

  25. A8Delta71-73 is the first antagonist of c5a that blocks C5a and C5adesArg74 binding to C5L2 making it a valuable tool for studying C5L2 functions. PMID: 14570896
  26. C5L2 on neutrophils diminishes during sepsis due to systemic generation of complement 5a (C5a), which is associated with a poor prognosis. PMID: 15634936

  29. C5L2 appears to bind complement factor C5a and C5a des Arg by different mechanisms, and, unlike C5a receptor (C5aR), C5L2 uses critical residues in its N-terminal domain for binding only to C5a des Arg. PMID: 17158873
  30. a major function of human C5L2 is to remove active complement fragments from the extracellular environment. PMID: 19100624

  32. Recombinant C3adesArg/acylation stimulating protein (ASP) is highly bioactive: a critical evaluation of C5L2 binding and 3T3-L1 adipocyte activation. PMID: 19767107
  33. C3a des Arg77 binds to C5L2 but not to the C3a receptor (LocusID: 719). C3a and C3a des Arg77 both stimulate triglyceride synthesis (acylation stimulating protein, ASP) in adipocytes and fibroblasts and so C5L2 could be the receptor for ASP. PMID: 12540846
  34. C5L2 is a high affinity binding protein for C5a and C5a des Arg74, and has a moderate affinity for C3a. Unlike the original receptors for C5a (CD88) and C3a (C3aR), C5L2 couples weakly to Gi-mediated signalling pathways. PMID: 11773063
