Information About B Cells
B cells belong to a group of white blood cells known as lymphocytes, making them a vital part of the immune system
The human body makes millions of different types of B cells each day that circulate in the blood and lymphatic system performing the role of immune surveillance. They do not produce antibodiesuntil they become fully activated. Each B cell has a unique receptor protein (referred to as the B cell receptor (BCR)) on its surface that will bind to one particular antigen.

If the pathogens are able to get past the first line of defence, for example, through a cut in your skin, and an infectiondevelops, the second line of defence becomes active. Through a sequence of steps called the immune response, the immune system attacks these pathogens.
The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system.
T helper cells: These cells are like the bosses. They give instructions to other cells by producing signals. Each T helper cell only looks out for one type of pathogen. Many T helper cells are needed to watch for many different diseases or invaders.
B cells: These produce antibodies, which lock onto the antigen of invading bacteria and immobilise them until the macrophage consumes them. Some B cells become memory cells after being activated by the presence of antigen. These cells are able to live for a long time and can respond quickly following a second exposure to the same

    They recognise the same protein that activated T cells. B cells produce antibodies that are the same as T cell receptors as they precisely recognise the protein belonging to the pathogen. The antibodies are then released from the B cells into the blood. They will then meet the pathogen and attach themselves onto it. Killer T cells activate as well if the pathogen is a virus. This enables another series of events which will destroy bacteria. When the bacteria are destroyed, the activated dendritic cells remain in lymph nodes and the B cells remain in contact with it, co-operating with it to ensure that the immunity is conserved. When the human body is healthy, the immune system has many cells ready to activate in case of an infection. When the battle is done, the cells will then deactivate slowly and some…

    The immune system is a network of cells, tissues, and organs that work together to fight off diseases and protect the body from infection and foreign antigens. Some examples of these antigens are: microbes, viruses, cancer cells, and toxins. The immune system has both innate immunity and adaptive immunity. Innate immunity is non-specific defense mechanism that is activated immediately when it encounters an antigen. Innate immunity has no memory system and therefore is unable to determine if an antigen is being encountered for the first time or if the body has already fought off the same antigen before. Adaptive immunity on the other hand, is a specific defense mechanism that has memory capacity which allows the body to recognize antigens…
