Overview in defense against microbes 1

Question 1

microbes does the immune system respond to?

Answer 1

bacteria, extracellular/intracellular (facultative/obligatory)
fungi, extracellular/intracellular
viruses
parasites, protozoan(unicellular)intracellular/extracellular and metazoan(multicellular)
tumors or malignant cells

Question 2

what immune cells respond to extracellular pathogens?

Answer 2

CD4+ T cell response and humoral immune response

Question 3

what immune cells response to intracellular pathogens?

Answer 3

CD8+ T cell response, CD4+ TH1 response

Question 4

what immune cells respond to metazoan parasites?

Answer 4

Th2 type response

Question 5

this is a field of immunology which results in an immune response against the microbe rather than the microbe itself; collateral damage

Answer 5

immunopathology

Question 6

outline the immune response steps?

Answer 6

breach in barrier
entry of pathogen
initial inflammation
recognition of PAMPs by PRRs of innate immune cells, innate immune cells active
cytokines/chemokines
recruitment of inflammatory cells
inflammation 
activation of APCs
different cytokine mileau
adaptive immune response
control of infection
