B-cells fight infection with the help of antibodies.
B-cells, which are found throughout the body and are part of the immune system, produce antibodies, which are Y-shaped proteins that attack and defend the body against viruses and bacteria.
Antibodies against pathogens are pathogen-specific.
They can latch on to the invading cell's surface and recognize it, allowing them to destroy immune cells.
As a result, B cells are thought to constitute the adaptive humoral immune system that regulates the synthesis of antigen-specific immunoglobulins in response to foreign particles and pathogens.
