Q

what are IFNs

A

protein cytokines

induce neighbour antiviral response

26
Q

what do cytokines do

A

induce and support proinflammatory respone

27
Q

what do complimentproteins recognize

A

PAMPSs

28
Q

IFN system

A

two phases

detection through the receptors
activation

29
Q

clearance of dead or dying cells

A

through macrophages that recognize PAMPs (PS or LPC) or DAMPs on apoptotic or necrotic cells

not on healhty cells expressing CD47

30
Q

how are fungal infectinos controlled

A

mostly by innate immunity

31
Q

fungi avoiding immune system

A

through capsules that block PRR binding giving them acquired immunity

32
Q

trypanosoma

A

african sleeping sickenss

have differnt forms of antigen and we remove one and the other grows

through duplication and translation of their genetic material

33
Q

what are the parasties

A

helminth
protozoa

34
Q

mycobacterium tuberculosis

A

forms granuloma inside a tubercle and inhibits phagolysosome fomration

releases lytic enzymes to destroy healthy tissue while infectino is contained

35
Q

bacerial evasion

A

iga degradation

gran +ve and some -ve resistant to compliment lysis

fibrins and m protein avoid phagolysossome

36
Q

N gonorrhea

A

degrade igA antibodies

37
Q

cytokine release syndrom

A

virus induced cytokine storm

38
Q

what disease was eliminated

A

measels but has no treatment

39
Q

HSV infection

A

infects epithelial cells

spreads to sensory cells

infects dorssal root ganglia

dormant in sensory neurons

40
Q

reactivation of HSV

A

sunlight
bact infection
aging
hormone changes
stress

41
Q

influenza

A

point mutations-antigenic drift
gene reassortment- antigenic shift

has segmneted genome

42
Q

orthomyxoviridae

A

infleunza

43
Q

polio symptoms

A

flu like
meningitis
paralysis
post polio syndrome- recover but muscle permantyly changed
no treatment

44
Q

long covid timeline

A

4 weeks persistnat symptoms

45
Q

what inc likelihood and dec likelihood of long covid

A

vaccination dec
reinfection inc

46
Q

masked palm civets

A

not covid resivoir bc no widespread infectino in wild or farmed civets plus they have no immunity to sars cov2

47
Q

intermediate hots for covid

A

wild animals and domestic animals

thought to be masked palm civets

48
Q

sars cov2 types

A

7 members
4 common cold
3 severe

49
Q

why do viruses emerge

A

globalization
air travel
poverty
limate change
mega cities
microbial evolution
deforestation

50

what reponse is for cytosolic and vesucular

A

type 1

56
