26829983 these data suggest that LLT1-CD161 interactions play a novel and important role in B cell maturation within the Germinal center in humans.
26147876 In RA joints, LLT1 is expressed by cells of the monocyte/macrophage lineage.
25760607 The hexamer of glycosylated LLT1 consists of three classical dimers. The hexameric packing may indicate a possible mode of interaction of C-type lectin-like proteins in the glycosylated form.
23333304 HIV-1 Vif downregulates the expression of C-type lectin domain family 2, member D (CLEC2D) in Vif-expression T cells
22664939 One polymorphism in LLT1 was found to be associated with our Crohn's Disease population (P<0.034).Our Ulcerative Colitis cohort was not associated with the variation in LLT1 (P=0.33)
21930700 LLT1 and CD161 have roles in modulating immune responses to pathogens; and interferon-gamma contributes to modulate immune responses
21572041 Molecular basis for LLT1 protein recognition by human CD161 protein (NKRP1A/KLRB1).
20843815 Data show that only CLEC2D isoform 1 (LLT1) is expressed on the cell surface.
20415786 LLT1 used Src-PTK, p38 and ERK signalling pathways, but not PKC, PI3K or calcineurin pathways, to increase production of IFN-gamma by human natural killer cells.
18593762 Observational study of gene-disease association. (HuGE Navigator)
18465072 Women with a lysine (GG genotype) at position 19 of the OCIL protein displayed lower bone mineral density at femoral neck and at lumbar spine sites than women having an asparagine residue.
18465072 Observational study of gene-disease association. (HuGE Navigator)
18453569 Expression of LLT1 on activated dendritic cells and B cells suggests that it might regulate the cross-talk between NK cells and APCs
16339513 LLT1 on target cells can inhibit NK cytotoxicity via interactions with CD161. LLT1 activates NFAT-GFP reporter cells expressing a CD3zeta-CD161 chimeric receptor; reciprocally, reporter cells with a CD3zeta-LLT1 chimeric receptor are stimulated by CD161
16339512 Engagement of CD161 on NK cells with LLT1 expressed on target cells inhibited NK cell-mediated cytotoxicity and IFN-gamma secretion. LLT1/CD161 interaction in the presence of a TCR signal enhanced IFN-gamma production by T cells
15123656 Data show that osteoclast inhibitory lectin (OCIL) binds a range of physiologically important glycosaminoglycans, and this property may modulate OCIL actions upon other cells [OCIL].
15104121 LLT1 induces Interferon Type II production by natural killer cells.
