Concept explainers

Immunology

Immunology is the division of science involved with the immune reactions occurring in living organisms. The organisms are accustomed to evolving internal defense mechanisms to evade the invasion of microbial pathogens. Diverse cells are connected with stimulating the immune responses, which produce inhospitable conditions to the microbes prompting their lysis and thus inhibits the multiplication of the pathogens. The immune system can distinguish the pathogens through the aid of cellular intercommunication and launch responses to destroy them.

Question

Cytotoxic T Cells kill:
Bacteria that are free floating in the blood stream
O Natural Killer Cells
O Viruses that are moving from one host cell to another host cell
O Helper T Cells
O Body cells that are presenting pathogenic antigens

[Select all answers that apply.]. The MHC (also known as the HLA on human cells) is a set of proteins on the surfaces of cells that:
O can signal cytotoxic T cells that the body cell is infected and should be killed.
O present the antigens of foreign invaders
O can signal that the cell is uninfected.
