The Essential Role of B Cells in Human Immune Defense
B cells are vital in our fight against many pathogens. They help keep us safe from infections. But, if they don’t work right, we can get sick with immune-related problems.
B Lymphocytes and Humoral Immunity Fundamentals
B lymphocytes, or B cells, are key for humoral immunity. They make antibodies that fight off pathogens and toxins. This is how our body stays safe from infections. Adoptive cell therapy uses B cells to boost our immune system.
When B cells meet specific antigens, they get activated. They then turn into plasma cells, which make lots of antibodies. These antibodies find and mark pathogens for destruction.
| B Cell Stage | Function |
|---|---|
| Naive B Cell | Recognizes antigens through surface-bound antibodies |
| Activated B Cell | Proliferates and differentiates into plasma cells or memory B cells |
| Plasma Cell | Produces large quantities of antibodies |
How Natural B Cells Recognize Pathogens
Natural B cells find pathogens with their surface-bound antibodies. This is a key step in fighting off infections. It lets B cells target specific pathogens.
“The ability of B cells to recognize and respond to antigens is fundamental to the adaptive immune response, providing a critical defense against infection.”
This specific recognition helps our immune system fight off many pathogens. It works against viruses, bacteria, toxins, and more.
What Are CAR B Cells and How Do They Work?
CAR B cells are a new way to fight cancer. They use the power of antibodies and the strength of cellular therapy. B cells are changed to find and attack cancer cells.
Engineering Process of Chimeric Antigen Receptors
To make CAR B cells, several steps are taken. First, B cells are taken from the patient. Then, they are changed to carry a special receptor. This receptor finds and attacks cancer cells.
The CAR construct has three parts: an outside part that finds the cancer, a middle part that connects it to the B cell, and an inside part that tells the B cell to act. The outside part finds the cancer, and the inside part tells the B cell to attack.
Comparing Natural vs. Engineered B Lymphocytes
Natural B cells help fight off infections by making antibodies. But, they might not always get cancer cells. CAR B cells are made to find and attack cancer cells better.
Engineered B cells are better at fighting cancer than natural ones. They can give the body a strong defense against cancer coming back.
