Classic studies by Rowe et al . (1) in the human and by Vitetta and coworkers (2) in the mouse have established that IgD is a major membrane immunoglobulin . This has led to a variety of studies and speculation regarding its biological function . Based upon the effect of anti-IgD on the in vitro primary response, Cambier et al . (3) suggested that the presence of IgD on the cell surface was cri...
The cDNA sequence of the Japanese flounder (Paralychthys olivaceus) IgD has been previously reported (GenBank accession no. AB052658) and this was followed by the detection of IgD mRNA expression in some flounder organ tissues. However, it has not been determined whether the flounder IgD gene is virtually expressed into IgD protein. To characterize the flounder immunoglobulins utilized in eluci...
Risk-taking is purported to be central to addictive behaviors. However, for Internet gaming disorder (IGD), a condition conceptualized as a behavioral addiction, the neural processes underlying impaired decision-making (risk evaluation and outcome processing) related to gains and losses have not been systematically investigated. Forty-one males with IGD and 27 healthy comparison (HC) male parti...
Mature, naive B cells coexpress IgD and IgM with identical binding sites. In this study, the binding properties of such IgM and IgD are compared to determine how size and shape may influence their ability to bind Ag and thus function as receptors. To dissect their intrinsic binding properties, recombinant IgM and IgD were produced in soluble form as monomers of the basic H(2)L(2) Ab architectur...
Monoclonal Ig deposition disease (MIDD) is a rare complication of monoclonal gammopathy characterized by deposition of monoclonal Ig light chains and/or heavy chains along the glomerular and tubular basement membranes. Here, we describe a unique case of IgD deposition disease. IgD deposition is difficult to diagnose, because routine immunofluorescence does not detect IgD. A 77-year-old man pres...
Background The umbrella term "Internet addiction" has been criticized for its lack of specificity given the heterogeneity of potentially problematic behaviors that can be engaged in online as well as different underlying etiological mechanisms. This has led to the naming of specific online addictions, the most notable being Internet Gaming Disorder (IGD). Methods Using the contemporary literatu...
IgD has remained a mysterious Ig class and a bane to immunology students since its discovery >40 years ago. Its spotty occurrence in mammals and birds and the discovery of an isotype with similarities to IgD in bony fish are perplexing. We have identified IgD heavy (H) chain (delta) from the amphibian Xenopus tropicalis during examination of the IgH locus. The Xenopus delta gene is in the same ...
OBJECTIVE To explore the structure of Internet gaming disorder (IGD) criteria and their distribution according to the different severity level of IGD. The associations of psychiatric comorbidities to each IGD symptom and to the IGD severity were also investigated. METHODS Consecutively recruited 330 Korean middle school students underwent face-to-face diagnostic interviews to assess their gam...
IgD, previously thought to be a recent addition to the immunoglobulin classes, has long been considered an enigmatic molecule. For example, it was debated if IgD had a specific function other than as an antigen receptor co-expressed with IgM on naive B cells and if it had an important role in mammalian immunity. However, during the past decade extensive sequencing of vertebrate genomes has show...
