Plasma cells (PCs) are terminally differentiated B-cells producing large amounts of immunoglobulins (Ig). In humans, most of circulating Ig are produced by bone marrow plasma cells. PCs differentiate from activated naïve or memory B-cells usually activated by specific antigens. It is still controversial whether the regulation of PCs numbers and the “active” in vivo Ig diversity depend or not on non-specific reactivation of B-cells during infections. Depending on the stimulus (T-independent/T-dependent antigen, cytokines, partner cells) and B-cell types (naïve or memory, circulating or germinal center, lymph nodes or spleen, B1 or B2...), both the phenotype and isotype of PCs differ suggesting that PC diversity is either linked to B-cell diversity or to the type of stimulus or to both. Knowledge of the mechanisms supporting PC diversity has important consequences for the management of i) plasma cell neoplasia such as Multiple Myeloma and Waldenström's Macroglobulinemia, ii) vaccine protection against pathogens and iii) auto-immune diseases.
The proceedings of a conference which aims to provide an up-to-date overview of current research in the nitric oxide field. This volume covers the biochemical and immunological aspects of the subject. Topics covered include the biological implications of nitric oxide synthesis.

Continuous cell lines derived from human cancers are the most widely used resource in laboratory-based cancer research. The first 3 volumes of this series on Human Cell Culture are devoted to these cancer cell lines. The chapters in these first 3 volumes have a common aim. Their purpose is to address 3 questions of fundamental importance to the relevance of human cancer cell lines as model systems of each type of cancer: 1. Do the cell lines available accurately represent the clinical presentation? 2. Do the cell lines accurately represent the histopathology of the original tumors? 3. Do the cell lines accurately represent the molecular genetics of this type of cancer? The cancer cell lines ...
Metabolic diseases and cancers account for half of all mortalities in the world, underscoring the significance of understanding the etiology of these diseases and developing effective therapies. Genomic research in the 21st century has brought cancer and metabolic disease, two once seemingly parallel ailments, as close to each other as they’ve ever been. Many genetic factors have been found to display functions regulating both cancer and metabolic disease. In this research topic: "Double-edged Swords: Genetic Factors That Influence The Pathogenesis of Both MetabolicDisease and Cancer", you will be introduced to individual genes, as well as genetic pathways that play important roles in influencing the progression of both metabolic disease and cancer. By no means covering an exhaustive list of genes qualified, this collection of articles rather serves as a precursor of what is yet to come in biomedical research. It paints the big picture of one of the major fields contributing to the future of “precision medicine”.
