Abstract
Natural killer (NK) cells express surface receptors that regulate potent effector functions, such as cytolytic activity and release of cytokines, which play a central role in inflammatory response and immunoregulation. In this paper, major advances are outlined from the original discovery of HLA-cla...

Abstract
Some primary immunodeficiencies (PIDs) express low serum levels of antibodies. The constant heavy G chain (IGHG) genes, also representing Fc domains of gamma 3, gamma 1 and gamma 2 on chromosome 14q32.3, genotyped by the alternative IgG subclass allotypes, found in four fixed IGHG haplotypes, design...

Abstract
We analyzed the natural killer cell immunoglobulin-like receptor (KIR) genes and immunoglobulin allotypes in the development of type 2 diabetes (T2D) based on body mass index (BMI) measurements (obese vs. non-obese) in Puerto Rican Americans. Genetic interactions between the KIR haplotype A homozygo...

Abstract
We indeed observed higher binding of the anti-CD16 monoclonal antibody (mAb) 3G8 on NK cells from V carriers (VV = VF > FF). However, the binding of two other anti-CD16 mAbs, LNK16 and DJ130c, decreased with the number of V allele (VV < VF < FF). CD16 transcript levels were independent on the genoty...

The IGHG (ImmunoGlobulin constant Heavy G chain) genes are situated close to the IGHE gene on chromosome 14q32, 5'mu, delta, gamma3, gamma1, alpha1, gamma2, gamma4, epsilon, alpha2, 3', in linkage disequilibrium. The polymorphism of gamma3, gamma1 and gamma2 genes, is investigated as alternative all...

Abstract
We have analyzed gene-targeted mice that carry a human and a mouse Igk C region genes. Using different methodologies, we found that cells expressing two distinct kappa-chains were 1.4-3% of all B cells and that they were present in the follicular, marginal zone, and B1 mature B cell subsets. When st...

Abstract
We show that while myeloma cells secrete IgA2m(2) predominantly as H(2)L(2), CHO cells secrete H(2)L and H(2) in addition to fully assembled H(2)L(2). When the CHO cells also synthesize J chain and secretory component (SC), polymeric IgA and secretory IgA in which SC is disulfide bonded to the polym...

We tested the effect of hydralazine, an antihypertensive drug that triggers lupus, on receptor editing, a chief mechanism of B lymphocyte tolerance to self-antigens. Using mice expressing transgenic human Igs, we found that hydralazine impairs up-regulation of RAG-2 gene expression and reduces secon...

The known IgG FcRs primarily mediate inflammation by interacting with IgG1, even though IgG2 isotypes tend to be more pathogenic. A novel FcgammaR that binds IgG2 but not IgG1 has just been identified, potentially explaining differences in biological activity that are seen with various IgG isotypes....

We immunized rabbits of the same Ig phenotype but born to homozygous mothers, and therefore not exposed to that allotype. Immunization was done in a3/a3 offspring of either a1/a3 or a3/a3 mothers, by injecting al IgG, and in b6/b6 offspring of b4/b6 or b6/b6 mothers, by injecting b4 IgG. The IgG was...

Abstract
We hypothesized that the repertoire shift from V(H)n to V(H)a B cells results from interactions between GALT and intestinal microflora. To test this hypothesis, we surgically removed organized GALT from newborn Alicia pups and ligated the appendix to sequester it from intestinal microflora. Flow cyt...

Using pulse-chase experiments, we have demonstrated that wild-type IgA2(n) with Arg(221) and Cys(241) and Cys(242) assembles through a disulfi...
