B-Cell Development Activation and Differentiation
13 nov 2014 · B cells are generated in the bone marrow • Takes 1-2 weeks to develop from hematopoietic stem cells to mature B cells |
How are B cells developed?
B-cell production in humans is a lifelong process that starts in the fetal liver intrauterine and bone marrow after birth.
Their development is from hematopoietic stem cells.What are the 4 stages of B-cell development?
B cell development takes place in a series of six main stages.
First, they start as common lymphoid progenitor cells, which become early pro-B cells, then late pro-B cells, next large pre-B cells, then small pre-B cells, and finally, immature B cells.30 mar. 2018To complete development, immature B cells migrate from the bone marrow into the spleen as transitional B cells, passing through two transitional stages: T1 and T2.
Throughout their migration to the spleen and after spleen entry, they are considered T1 B cells.
Within the spleen, T1 B cells transition to T2 B cells.
What are the steps of B-cell activation?
B cells carry a unique B-cell antigen receptor (BCR) on their cell surface.
The BCR has two roles in B-cell activation.
First, BCR will bind to its specific antigen.
Second, it delivers the cellular message from the binding site through the cell to the nucleus and intracellular sites.
A Highlight of The Vital Processes During The 7 B Cell Development Stages
It is important that we try to highlight what goes on through the seven stages of B cell development before your body has mature functional B cells. The goal of this whole process is to have a mature B cell (Stage 7) that has all the necessary “tools” needed to recognize and fight an attacker (Microorganisms). The most important marker that a matur
The 7 Stages of B Cell Development
We shall now discuss the seven B cell development stages here. Beginning with the most primitive stage we shall walk through to the most advanced that gives rise to the mature B cells. The mature functional B cells protect you as part of the adaptive immune system. immunostudies.com
Regulation of B Cell Development
This process must be regulated to ensure the mature naïve B cellsthat will finally be released into your peripheral circulation are not harmful. Being harmful means that they can attack your own cells and destroy them (autoimmunity). That is obviously not what they are meant to do. The B cells should only protect you against foreign bodies in an id
Positive Selection of The Developing B Cells
In positive selection, your developing B cells are selected for survival if the pre-B receptor binds its ligand successfully. What this means is that those B cells have receptors that can recognize and respond to foreign antigens. These are considered helpful cells. The process of removal of inappropriate cells here is similar to what happens with
Negative Selection of The Developing B Cells
This involves the developing B cells that interact with your own cells in the bone marrow through their pre-B cell receptor. If they do so with high affinity, that means that those cells are potentially autoreactive (can cause autoimmunity). They are killed to avert that situation in the future – what an intelligent system Therefore, the B cells t
Conclusion
The development of B cells in a normal human body goes through seven important stages. Each stage is characterized by several activities that make it unique and something that scientists can map in the laboratory. That means it is possible to analyze your bone marrow sample or blood sample and tell how many B cells are in what stages of development
