[PDF] b cell differentiation antigens

Immature B cell leaves the bone marrow and undergoes further differentiation. When a naive or memory B cell encounters antigen in an environment and the aid of a T cell, BCRs stimulation induces B cell differentiation into an antibody-secreting effector cell.

  • What is B cell differentiation?

    B cell differentiation is tightly controlled by a transcription regulation network. It involves the coordination of several transcription factors to promote the expression of antibody-secretion and plasma cell-related genes, and downregulate the B cell identity genes.1 sept. 2019

  • When B cells are presented with antigen they differentiate?

    When naïve or memory B cells are activated by antigen (and helper T cells—not shown), they proliferate and differentiate into effector cells. The effector cells produce and secrete antibodies with a unique antigen-binding (more)

  • What are differentiation antigens?

    Differentiation antigens are derived from proteins that are expressed in a given type of tumor and the corresponding healthy tissue. Most identified differentiation antigens are present on melanoma cells, in which the corresponding protein is often involved in melanin biosynthesis or melanosome biogenesis.
  • Armed helper T cells stimulate the proliferation and then the differentiation of antigen-binding B cells. The specific interaction of an antigen-binding B cell with an armed helper T cell leads to the expression of the B-cell stimulatory molecule CD40 (more)
