How b cells mature
B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system. B cells produce antibody molecules which may be either secreted or inserted into the plasma membrane where they serve as a part of B-cell receptors. When a naïve or memory B cell is activated by an antig… WebClick the card to flip 👆. 1) A hematopoietic stem cell undergoes differentiation and genetic rearrangement to produce. 2) immature lymphocytes with many different antigen receptors.

WebMature IgG+ B cells prime Fc-specific Treg via recycling of surface immunoglobulin with an antigen-processing pathway that is very efficient in presenting immunodominant Fc peptides to Treg. Some of these peptides are pan-HLA binders, explaining the presence of Fc-specific Treg in circulation in healthy pediatric and adult subjects.
