Lipopolysaccharide-induced inflammation can induce a significant ficolin response.
Title: The ficolin response to LPS challenge in mice.
this study demonstrates that ficolins are important in initial innate host defense against Aspergillus fumigatus infections in vivo
Title: Ficolins Promote Fungal Clearance in vivo and Modulate the Inflammatory Cytokine Response in Host Defense against Aspergillus fumigatus.
this study shows that FCN B plays an important role in the development of collagen Ab-induced arthritis
Title: Deconstructing the Lectin Pathway in the Pathogenesis of Experimental Inflammatory Arthritis: Essential Role of the Lectin Ficolin B and Mannose-Binding Protein-Associated Serine Protease 2.
Ficolin-2 defends against virulent Mycobacteria tuberculosis infection in vivo, and its insufficiency is associated with infection in humans.
Title: Ficolin-2 defends against virulent Mycobacteria tuberculosis infection in vivo, and its insufficiency is associated with infection in humans.
Data show that ficolin-B is stored in and set free from immature granulocytic myeloid cells indicating a role in the early infection-induced cellular response of these inflammatory cells.
Title: Immature mouse granulocytic myeloid cells are characterized by production of ficolin-B.
FcnA-deficient and FcnA/ficolin B double-deficient mice lack FcnA-mediated complement activation in the sera, because of absence of complexes comprising FcnA and MBL-associated serine proteases.
Title: Mice deficient in ficolin, a lectin complement pathway recognition molecule, are susceptible to Streptococcus pneumoniae infection.
These results identify mouse ficolin-B as a functional member of the ficolin family activating complement via the lectin pathway.
Title: Functional analysis of mouse ficolin-B and detection in neutrophils.
Results show that ficolin B in mouse bone marrow is an oligomeric protein. Ficolin B contained very low, but detectable, amounts of MASP-2 and sMAP and showed detectable C4-deposition activity on immobilized N-acetylglucosamine.
Title: Mouse ficolin B has an ability to form complexes with mannose-binding lectin-associated serine proteases and activate complement through the lectin pathway.
Ficolin B showed multimeric structures and revealed binding to both N-acetylglucosamine and N-acetylgalactosamine. Ficolin B specifically recognized sialic acid residues. Ficolin B plays a distinct role through its unique carbohydrate-binding specificity.
Title: Carbohydrate-binding specificities of mouse ficolin A, a splicing variant of ficolin A and ficolin B and their complex formation with MASP-2 and sMAP.
Ficolin B exhibited a distinct ontogeny pattern that switched from embryonic liver to postnatal bone marrow and spleen. The cells that express ficolin B mRNA were identified as belonging to the myeloid cell lineage.
Title: Ficolin A and ficolin B are expressed in distinct ontogenic patterns and cell types in the mouse.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
