6. Immunity Infection and Forensics Flashcards
(3 cards)
1
Q
phagocytosis
A
phagocytes engulf and destroy pathogens
2
Q
explain why macrophages play a role in in the antigen specific immune response to viruses but neutrophils do not
A
macrophages phagocytose pathogens
macrophages present antigens to T cells
macrophages produce cytokines involved in the immune response
3
Q
How does m.tuberculosis bacteria evade the immune system
A
- M. tuberculosis survive inside macrophages by having a thick waxy coat/ cell wall
- m tuberculosis remain dormant in tubercules
- they inhibit T helper cells and suppress the acquired immune response. Antigen presentation is disrupted
