A postdoctoral fellow is studying the immune system. She is focusing on receptors that undergo irreversible genetic recombination of antigen receptor gene segments. Which of the following cells are involved in this process?

A. Neutrophils
B. Macrophages
C. Dendritic Cells
D. Complement
E. B-cells

The correct answer is E.
The adaptive immune system involves receptors that recognize pathogens and undergo VDJ recombination (an irreversible genetic recombination of antigen receptor gene segments) during lymphocyte development. Response is slow on first exposure, but subsequent memory response is faster and more robust. The innate immunity involves neutrophils, macrophages, dendritic cells and complement.
