Cellular Immunology

Cellular immunology is the study of the immune system's cellular components, which are crucial in defending the body against infections and diseases. Key cells include T cells, which attack infected or cancerous cells, and B cells, which produce antibodies that identify and neutralize foreign pathogens like viruses and bacteria. These cells communicate and work together to orchestrate an immune response, providing the body with the ability to remember past infections and respond more effectively in the future. This process is vital for maintaining health and preventing illnesses.
