Clone Selection

Clone selection is a process in the immune system where specific immune cells, called B-cells, are identified and multiplied to fight a particular threat, like a harmful virus or bacteria. When the body detects an invader, it activates the B-cell that best recognizes it, then duplicates that cell many times to produce enough antibodies to neutralize the threat. This targeted amplification ensures a strong, efficient response, creating many identical clones specialized for the specific invader, ultimately helping the body recover and remember the pathogen for future protection.
