interferons
a class of antiviral proteins that interfere with viral multiplication
yes
are interferons host-cell specific?
NO
are interferons virus-specific?
gamma
INF that causes macrophages to produce nitric oxide, kills bacteria, and tumor cells by inhibiting ATP production
gamma
INF that increases expression of class I and class II molecules and increase antigen presentation
alpha and beta
INF produced by virus-infected host cells. they react with plasma or nuclear membrane receptors, inducing synthesis of AVPs
antiviral proteins
proteins that disrupt various stages of viral multiplication
iron binding proteins
proteins that transport and store iron
transferrin, lactoferrin, ferritin, hemoglobin
4 types of iron binding proteins
siderophores
proteins secreted by pathogenic bacteria to obtain iron
antimicrobial peptides
short peptides that inhibit cell wall synthesis, form pores in plasma membranes, destroy DNA and RNA
dermicidin, defensins, cathelicidins, thrombocidin
four examples of antimicrobial peptides
