Phenotypic diversity of natural killer (NK) populations in patients with NK-type lymphoproliferative disease of granular lymphocytes.
Using monoclonal antibodies (MoAbs) termed GL183 and EB6, directed to a novel family of natural killer (NK) specific triggering molecules, four functional subsets of NK cells have been recently defined (GL183+EB6-; GL183+EB6+; GL183-EB6+; GL183-EB6-). In healthy individuals, all these subsets are represented in variable portion. The expression of EB6 and GL183 surface antigens has been analyzed...

Background: The HLA class I molecules serve as ligands for both T cell receptors and killer cell immunoglobulin-like receptors (KIRs). Objective: We investigated the HLAC and HLA-Bw4 alleles as well as KIRs expression on CD56 positive lymphocytes to evaluate whether these genes and molecules could influence Ankylosing spondylitis (AS) susceptibility, alone or in combination. Methods: We typed 4...
متن کاملT cell receptor beta chain gene rearrangements in lymphoproliferative disorders of large granular lymphocytes/natural killer cells
Twelve cases of T gamma LPD (lymphoproliferative disorders of Fc gamma receptor-bearing T cells) involving an expansion of large granular lymphocyte/natural killer (LGL/NK) cells were investigated for the expression of LGL/NK-associated markers and for T beta gene rearrangement. All the cases selected were classified as T gamma LPD on the basis of morphology, function, and phenotype of the circ...
