Which of the following cell types does NOT engulf and degrade pathogens?
a. macrophages
b. B cells
c. dendritic cells
d. neutrophils
e. T cells
Homework Answers
e.T cells.
The neutophils,B cells, dendritic cells and macrophages degrade the pathogen by the process of phagocytosis.But, when the macrophage engulf the pathogen, breaks them into the peptide and its antigen.The antigen is presented on the MHCs which makes them the antigen presenting cell.Then, the CD4 macrophage antigen presenting cell binds with the CD4 T helper cells and with the CD4 receptors.Following to that, clonal expansion occurs and T helper cells divides into the active T helper cells and T memory cells, which acts upon the pathogen to kill them.
