Crystal structure of the human monocyte-activating receptor, "Group 2" leukocyte Ig-like receptor A5 (LILRA5/LIR9/ILT11).
Human leukocyte Ig-like receptor B1 (LILRB1) and B2 (LILRB2) belong to "Group 1" receptors and recognize a broad range of major histocompatibility complex class I molecules (MHCIs). In contrast, "Group 2" receptors show low similarity with LILRB1/B2, and their ligands remain to be identified. To date, the structural and functional characteristics of Group 2 LILRs are poorly understood. Here we ...
متن کاملKiller cell Ig-like receptor and leukocyte Ig-like receptor transgenic mice exhibit tissue- and cell-specific transgene expression.
To generate an experimental model for exploring the function, expression pattern, and developmental regulation of human Ig-like activating and inhibitory receptors, we have generated transgenic mice using two human genomic clones: 52N12 (a 150-Kb clone encompassing the leukocyte Ig-like receptor (LILR)B1 (ILT2), LILRB4 (ILT3), and LILRA1 (LIR6) genes) and 1060P11 (a 160-Kb clone that contains t...
متن کاملCharacterisation of Bovine Leukocyte Ig-like Receptors
Leukocyte Immunoglobulin-like receptors (LILR) are innate immune receptors involved in regulating both innate and adaptive immune functions. LILR show more interspecies conservation than the closely related Killer Ig-like receptors, and homologues have been identified in rodents, primates, seals and chickens. The murine equivalents, paired Ig-like receptors (PIR), contain two additional immunog...
متن کاملCrystal structure of myeloid cell activating receptor leukocyte Ig-like receptor A2 (LILRA2/ILT1/LIR-7) domain swapped dimer: molecular basis for its non-binding to MHC complexes.
The leukocyte Ig-like receptor (LILR/ILT/LIR) family comprises 13 members that are either activating or inhibitory receptors, regulating a broad range of cells in the immune responses. LILRB1 (ILT2), LILRB2 (ILT4) and LILRA1 (LIR6) can recognize MHC (major histocompatibility complex) class I or class I-like molecules, and LILRB1/HLA-A2, LILRB1/UL18 and LILRB2/HLA-G complex (extracellular domain...
متن کاملIg-like transcript 2 (ILT2)/leukocyte Ig-like receptor 1 (LIR1) inhibits TCR signaling and actin cytoskeleton reorganization.
Ig-like transcript 2 (ILT2)/leukocyte Ig-like receptor 1 (LIR1) is a receptor, specific for MHC class I molecules, that inhibits lymphoid and myeloid cells. Here, we analyzed the molecular and cellular mechanisms by which ILT2 modulates T cell activation in primary CTLs and transfected T cell lines. We found that cross-linking with the TCR and the activity of Src tyrosine kinase p56(lck) were r...
