Journal ArticleDOI
P58 molecules as putative receptors for major histocompatibility complex (MHC) class I molecules in human natural killer (NK) cells. Anti-p58 antibodies reconstitute lysis of MHC class I-protected cells in NK clones displaying different specificities.

TL;DR: Support to the concept that p58 molecules represent a NK receptor delivering a negative signal was provided by experiments in which the entire anti-p58 mAbs could inhibit the lysis of unprotected Fc gamma R- target cells, thus mimicking the inhibitory effect of MHC class I molecules.
Journal ArticleDOI
Identification of four subsets of human CD3-CD16+ natural killer (NK) cells by the expression of clonally distributed functional surface molecules: correlation between subset assignment of NK clones and ability to mediate specific alloantigen recognition.
Alessandro Moretta,Cristina Bottino,Daniela Pende,Gino Tripodi,Giuseppe Tambussi,O Viale,Anna Maria Orengo,M Barbaresi,Annalisa Merli,Ermanno Ciccone +9 more
TL;DR: Peptide map analysis indicated that EB6 (or GL183) molecules precipitated from double-positive clones were identical to the corresponding molecules isolated from single-positive ones, thus indicating that the two antigenic determinants are carried by two distinct molecules.
Journal ArticleDOI
CD69-mediated pathway of lymphocyte activation: anti-CD69 monoclonal antibodies trigger the cytolytic activity of different lymphoid effector cells with the exception of cytolytic T lymphocytes expressing T cell receptor alpha/beta.
Alessandro Moretta,A. Poggi,Daniela Pende,Gino Tripodi,Anna Maria Orengo,Nicoletta Pella,Raffaella Augugliaro,Christina Bottino,Ermanno Ciccone,Lorenzo Moretta +9 more
TL;DR: It appears that CD69 molecules may initiate a pathway of activation of cytolytic functions common to a number of activated effector lymphocytes with the remarkable exception of TCR alpha/beta+ cy tolytic cells.
Journal ArticleDOI
Involvement of HLA class I alleles in natural killer (NK) cell-specific functions: expression of HLA-Cw3 confers selective protection from lysis by alloreactive NK clones displaying a defined specificity (specificity 2).
Ermanno Ciccone,Daniela Pende,O Viale,A Than,C Di Donato,Anna Maria Orengo,Roberto Biassoni,Simonetta Verdiani,Antonio Amoroso,Alessandro Moretta +9 more
TL;DR: It is inferred that Cw3 expression on (both human and murine) target cells confers selective protection from lysis mediated by anti-2 NK clones, which could represent the element conferring selective resistance to lysis byAnti-2 clones.
Journal ArticleDOI
Evidence of a natural killer (NK) cell repertoire for (allo) antigen recognition: definition of five distinct NK-determined allospecificities in humans.
Ermanno Ciccone,Daniela Pende,O Viale,C Di Donato,Gino Tripodi,Anna Maria Orengo,John Guardiola,Alessandro Moretta,L. Moretta +8 more
TL;DR: The comparative analysis of the segregation of the major histocompatibility complex haplotypes and the recessive or dominant alleles of the genes governing the five specificities analyzed indicated that there is no independent sampling between the two genetic traits, thus suggesting that the genes regulating the NK-defined specificities are carried by chromosome 6.
