Human C-type lectin domain family 9 member A(CLEC9A) ELISA kit

Functions as an endocytic receptor on a small subset of myeloid cells specialized for the uptake and processing of material from dead cells. Recognizes filamentous form of actin in association with particular actin-binding domains of cytoskeletal proteins, including spectrin, exposed when cell membranes are damaged, and mediate the cross-presentation of dead-cell associated antigens in a Syk-dependent manner.

1. Clec9a is responsible for the antigen cross-presentation of dendritic cell subsets and may be a target of immunotherapy PMID: 27250027
2. findings demonstrate that CLEC9A is a specialized receptor that modulates the innate immune response when there is a mycobacterial infection PMID: 29065139
3. Data indicate that blood dendritic cell antigen 3 BDCA3(+) and C-type lectin domain family 9, member A CLEC9A(+) dendritic cells (DC) are of major importance in the induction of anti-viral and anti-tumor immunity. PMID: 24910448
4. Activated dendritic cell subsets expressing CD141/CLEA9A/CD1c, likely recruited into the tubulointerstitium, are positioned to play a role in the development of fibrosis and, thus, progression to chronic kidney disease. PMID: 24049150
5. study showsn that the DNGR-1 ligand is preserved from yeast to man and corresponds to the F-actin component of the cellular cytoskeleton; identification of F-actin as a DNGR-1 ligand suggests that cytoskeletal exposure is a universal sign of cell damage that can be targeted by the innate immune system to initiate immunity PMID: 22483800
6. High expression of DNGR-1 specifically and universally identifies a unique dendritic cells subset in mouse and humans. PMID: 22442345
7. propose that Clec9A provides targeted recruitment of the adaptive immune system during infection and can also be utilized to enhance immune responses generated by vaccines. PMID: 22483802
8. Data show that CLEC9A is only expressed on immature BDCA3(+) myeloid dendritic cells (mDCs). PMID: 22234694
9. For production of cytotoxic T cells, transgenic DEC-205 and Clec9A, but not Clec12A, are effective targets for antibody-mediated delivery of antigens for vaccination, although only in the presence of adjuvants. PMID: 21677141
10. A population of human dendritic cells (DC) that expresses DNGR-1 (CLEC9A) and high levels of BDCA3 and resembles mouse CD8alpha+ DCs in phenotype and function, is characterized. PMID: 20479117
11. DC, NK lectin group receptor-1 (DNGR-1) is a C-type lectin of the NK cell receptor group PMID: 18497879
12. CLEC9A functions as an activation receptor PMID: 18408006
13. analysis of differences between mouse and human Clec9A PMID: 18669894
14. CLEC9A functions as a SYK-coupled C-type lectin receptor to mediate sensing of necrosis by the principal dendritic-cell subset involved in regulating cross-priming to cell-associated antigens PMID: 19219027
15. The paper cited (J Clin Invest. 2008 Jun;118(6):2098-110) is the first characterization of human and mouse CLEC9A (a.k.a DNGR-1) PMID: 18497879
