HLA Mismatching Favoring Host-Versus-Graft NK Cell Activity Via KIR3DL1 Is Associated With

HLA-Bw4 recipients of HLA-Bw6 grafts have enhanced host-versus-graft (HVG) NK cell activity mediated by KIR3DL1 ligand. Because natural killer (NK) cells may promote tolerance by depleting antigen-presenting cells, we hypothesized improved outcomes for HLA-Bw4 recipients of HLA- Bw6 grafts. We evaluated differences in acute cellular rejection (ACR) and CLAD-free survival across 252 KIR3DL1+ recipients from UCSF. -

The Journal of Immunology Killer Cell Ig-Like Receptor and Leukocyte Ig-Like Receptor Transgenic Mice Exhibit Tissue- and Cell-Specific Transgene Expression1 Danny Belkin,* Michaela Torkar,* Chiwen Chang,* Roland Barten,* Mauro Tolaini,† Anja Haude,* Rachel Allen,* Michael J. Wilson,* Dimitris Kioussis,† and John Trowsdale2* 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 ten killer cell Ig-like receptor (KIR) genes). Both the KIR and LILR families are encoded within the leukocyte receptor complex, and are involved in immune modulation. We have also produced a novel mAb to LILRA1 to facilitate expression studies. The LILR transgenes were expressed in a similar, but not identical, pattern to that observed in humans: LILRB1 was expressed in B cells, most NK cells, and a small number of T cells; LILRB4 was expressed in a B cell subset; and LILRA1 was found on a ring of cells surrounding B cell areas on spleen sections, consistent with other data showing monocyte/macrophage expression. KIR transgenic mice showed KIR2DL2 expression on a subset of NK cells and T cells, similar to the pattern seen in humans, and expression of KIR2DL4, KIR3DS1, and KIR2DL5 by splenic NK cells. These observations indicate that linked regulatory elements within the genomic clones are sufficient to allow appropriate expression of KIRs in mice, and illustrate that the presence of the natural ligands for these receptors, in the form of human MHC class I proteins, is not necessary for the expression of the KIRs observed in these mice. -

To understand the molecular basis of this ing intracellular immunoreceptor tyrosine-based inhibitory receptor-ligand recognition, we have crystallized the extra- motifs (ITIM), whereas KIR2DS molecules appear to be cellular ligand-binding domains of KIR2DL2, a member of the noninhibitory receptors with shorter intracellular tails that Ig superfamily receptors that recognize HLA-Cw1, 3, 7, and 8 interact with an immunoreceptor tyrosine-based activation allotypes.

Similar to other cancers, MM targets may elude NK cell immunosurveillance by reprogramming tumor microenvironment and editing cell surface antigen repertoire. Along disease continuum, these effects collectively result in a pro- gressive decline of NK cell immunity, a phenomenon increasingly recognized as a critical determinant of MM progression. In recent years, unprecedented efforts in drug devel- opment and experimental research have brought about emergence of novel therapeutic interventions with the potential to override MM-induced NK cell immunosuppression.
