Q.
Select the correct statement with respect to disease and immunization :
AIPMTAIPMT 2011Human Health and Disease
Solution:
The primary and secondary immune responses are carried out with the help of two special types of lymphocytes present in our blood, ie, B-lymphocytes and T-lymphocytes. The B-lymphocytes produce an array (a range) of proteins in response to pathogens into our blood to fight with them. These proteins are called antibodies. The T-cells themselves do not secrete antibodies but help B-cells to produce them.
