Association of the LILRA3 deletion with B-NHL and functional characterization of the immunostimulatory molecule.

LILRA3 is the sole soluble member of the LILR family. Previous studies from our group had shown that a 6.7 kb genetic deletion of LILRA3 is associated with MS and Sjögren's syndrome.

Association of an NKG2D gene variant with systemic lupus erythematosus in two populations.

NKG2D, involved in T-cell activation and viral defense, shows a single-nucleotide polymorphism (SNP) in the transmembrane region, characterized by a substitution of alanine with threonine. We examined the association of systemic lupus erythematosus (SLE) with one of the NKG2D gene variants. We also studied the functional impact of that allele in SLE.

Immunoglobulin-like transcripts as risk genes for autoimmunity.

Risk genes for multiple sclerosis (MS) are localized in the gene regions 6p21-11 and 19q13, the latter harboring the genes of the immunoglobulin-like transcripts (ILTs). ILTs are a family of activating and inhibitory receptors expressed on antigen-presenting cells (APCs) as well as on natural killer (NK) and T cells. Because of the inhibitory function of ILT2 and ILT4 and their binding to human leukocyte antigen (HLA)-G, they play a role in immune tolerance and may be important in pathogenesis of autoimmunity.
