How do beta cells work
WebDec 12, 2005 · The β-cells must sense and respond suitably to postprandial increases of blood glucose, and perturbation of glucose-sensing in these cells can lead to hypoglycaemia or hyperglycaemias and ultimately diabetes. Here, we review β-cell glucose-sensing with a particular focus on the regulation of cellular excitability and exocytosis. WebMoreover, although the beta cells from the mutant mice still released insulin to elevated glucose, they did not do so in a pulsatile fashion, as was the case in the wild type (Ravier et al., 2005). Thus, the secretory output of beta cells appears to …

WebThere are two main types of B-cells: plasma cells and memory cells. Both types help protect you from infection and disease. Plasma cells: Plasma cells release antibodies in response to antigens. Once a B-cell becomes a mature plasma cell, it can release up to 2,000 antibodies per second. Plasma cells are also called plasmacytes or effector cells.
