Question
Identify the cell that is responsible for the primary and secondary immune response. Describe, in details, how each process occurs. Give the normal percentage range expected in a normal CBC report.Then, discuss the importance of the relationship of primary and secondary immune response in reference to the detection, the treatment, and vaccine development for parasitic infections.

Explanation / Answer
The cells responsible for primary immune response are Antigen presenting cells, helper T cells and B cells. When an antigen is encountered by an APC, it processes it and present it on the surface with the help of MHCII complex. It is recognized by helper T cells. Helper T cells secrete lymphokines and stimulate B cells. B cells divide into Plasma cells and memory cells. Plasma cells secrete antibodies against the antigen and special reactions take place to eradicate the antigens. This is called as primary immune response. When ever in future same antigen is encountered with in the body, the memory B and T cells launch a strong attack against the pathogen. This is called as secondary response. The B and T cells are commonly called as lymphocytes. Their normal percentage range in a normal CBC is 2--10%
The development of various vaccines against different diseases is based on the mechanism of working of immune systems. When ever a vaccine is given to a baby, it stimulates the primary immune response and formation of memory cells. So, when a disease causing agent attacks the body, the trained immune system launches a vigorous attack on the pathogen.
