Functional studies have identified two distinct p 58 KIR , each reactive with a different group of HLA C allotypes , and distinct p 70 KIR specific for some HLA B or HLA A allotypes . ^^^ Here , we show that a soluble p 70 KIR binds to HLA B * 5101 , but not to HLA A or HLA C molecules . ^^^ Truncated soluble forms of the HLA B * 5101 specific p 70 KIR , including one with two immunoglobulin ( Ig ) domains reactive with a monoclonal antibody that blocks p 70 KIR function , did not bind to HLA B * 5101 , indicating that all three Ig domains are required for binding . . ^^^ |

We also investigated the frequency of HLA B alleles sharing the same natural killer cell immunoglobulin like receptor ( KIR ) binding sequence with HLA B 51 . ^^^ HLA B alleles reacting with the sequence specific oligonucleotide probe 23 , which corresponds to the KIR binding site of B * 51 , were found to be positive in 127 BD patients ( 73 % ) and 90 controls ( 47 % ) ( OR = 3 . 03 , 95 % CI 2 4 . 7 ) . ^^^ The repeated RPE analysis after separating HLA B alleles carrying B 51 KIR binding sequence as distinct alleles within a broad type allele group revealed B * 2702 allele as the only allele showing an association with BD after the deletion of B * 51 . ^^^ |

Associations between KIR epitope combinations expressed by HLA B / C haplotypes found in an HIV 1 infected study population may influence NK mediated immune responses . ^^^ We observed a significant association between particular combinations of KIR epitopes expressed by HLA B / C haplotypes and propose that the repertoire of KIR epitopes expressed by HLA B and HLA C alleles within the context of particular haplotypes may be an important component of the NK mediated immune response to HIV and / or other infectious pathogens . . ^^^ |

In contrast to the KIR2D : HLA C interaction , little is known of KIR3DL1 ' s interaction with HLA B or the role of D 0 , the domain not present in KIR2D . ^^^ Domain swap , deletion , and site directed mutants of KIR3DL1 were analyzed for HLA B binding using a novel , positively signaling cell cell binding assay . ^^^ Natural ' deletion ' of residues 50 and 51 from its D 0 domain causes Pt KIR3DL1 / 2 to bind Bw 4 ( + ) HLA B allotypes more avidly than does KIR3DL1 . ^^^ Deletion of these residues from KIR3DL1 , or their substitution for alanine , enhanced binding of Bw 4 ( + ) HLA B . ^^^ None of 15 different point mutations in D 0 abrogated KIR3DL1 binding to Bw 4 ( + ) HLA B . ^^^ |

The NKB 1 and HP 3E4 NK cells receptors are structurally distinct glycoproteins and independently recognize polymorphic HLA B and HLA C molecules . ^^^ Recently , we described an NK cell receptor , NKB 1 , that inhibits NK cells from killing target cells expressing Bw 4 reactive HLA B molecules ( B * 2705 , B * 5101 , B * 5801 ) . ^^^ |

The Bw 4 public epitope of HLA B molecules confers reactivity with natural killer cell clones that express NKB 1 , a putative HLA receptor . ^^^ These results show that the presence of the Bw 4 epitope influences recognition of HLA B molecules by NK cells that express NKB 1 , and suggest that the NKB 1 molecule may act as a receptor for Bw4+ HLA B alleles . ^^^ Sequences outside of the Bw 4 region must also affect recognition by NKB1+ NK cells , because lysis of transfectants expressing HLA A * 2403 or A * 2501 , which possess the Bw 4 epitope but are in other ways substantially different from HLA B molecules , was not increased by addition of the anti NKB 1 antibody . ^^^ |

Conserved and variable residues within the Bw 4 motif of HLA B make separable contributions to recognition by the NKB 1 killer cell inhibitory receptor . ^^^ Allotypes from four divergent HLA B families ( B 8 , B 15 , B 16 , and B 27 ) were compared for their inhibition of cytolysis by NK cells expressing the NKB 1 receptor . ^^^ HLA B allotypes having four different Bw 4 motifs were examined and all interact with NKB 1 . ^^^ Three types of polymorphism are implicated in formation of the ligand recognized by NKB 1 : ones shared by Bw 4 motifs ; ones distinguishing Bw 4 motifs ; and ones outside the Bw4 / Bw6 region that distinguish HLA B from HLA A . . ^^^ |
