Their specificity arises due to the recombination of Variable, Diversity, and Joining genes.
One type of them secretes perforin and granzymes, and another type was discovered in birds in an organ called Bursa of Fabrisius. Their specificity arises due to the recombination of Variable, Diversity, and Joining genes. All receptors on their surface are identical and contain light and heavy chains. Basophil and Neutrophil are granulocytes which are examples of these cells which bind to antigens. Consisting of NK, B, and T cells, for 10 points, identify these cells that are sometimes called lymphocytes.
