To study the adaptation of natural killer (NK) cells to their major histocompatibility complex (MHC) class I environment we have established a novel mouse model with mosaic expression of H-2D(d) using a Cre/loxP system. In these mice, we noticed that NK cells expressing the inhibitory receptor for D(d), Ly49A, were specifically underrepresented among cells with low D(d) levels. That was due to ...

Background The extreme variability at the Killer cell Immunoglobulin like Receptor (KIR) expressed on the surface of natural killer cells interacts with Human Leukocyte Antigen (HLA) Class I appear to play a crucial role in the outcome against viral infection. The combination of HLA/KIR gene products either individually or collectively have been implicated in the control of HIV-1 in various pop...

T-cell large granular lymphocytes (LGLs) are a morphologically distinct subset of normal peripheral blood mononuclear cells classified into two major lineages based on the presence of the CD3 receptor: CD3+ lymphocytes and CD3natural killer cells. The revised European-American classification of lymphoid neoplasms [2] considers clonal proliferation of these cells, or LGL leukaemia (as proved by ...

CD155 is the fifth member in the nectin-like molecule family, and functions as the receptor of poliovirus; therefore, CD155 is also referred to as necl-5, or PVR. As an immunoglobulin-like adhesion molecule, CD155 is involved in cell motility, and natural killer and T cell-mediated immunity. CD155 is barely or weakly expressed in various normal human tissues, but frequently overexpressed in hum...
