key cards Flashcards
CD56
NK cells
CD38/138
plasma cells
influenza virus tx
M2 channel inhibitors, NA inhibitors, vaccines
DHFR inhibitors
- antifungal
- inhibit folate (and thus pyrimidine) synthesis
- ex = TMP-SMX
CD19
B cells
TNF-alpha
pro-inflammatory
azoles
- antifungal
- inhibit ergosterol synthesis via inhibition of cyp p450
- ex = fluconazole, itraconazole
chagas disease dx
amastigotes in cardiac tissue or serology
leishmaniasis dx
skin biopsy or culture
allylamines
- antifungal
- inhibit squalene epoxidase, an earlier step in ergosterol synthesis
- ex = terbinafine
CD80/86
- B7 on APC’s
- Bind CD28 and activate T cells
IL-8
recruits neutrophils
norovirus tx
supportive
leishmaniasis clinical manifestiations
- visceral = kala-azar
- cutaneous = non-healing ulcer
- mucotaneous
IL-4
- promotes B cell growth and class switching to IgE and IgG
- promotes Th2 differentiation and inhibits Th1 differentiation
rotavirus tx
oral rehydration, oral vaccine
IL-13
activates eosinophils
TGF-beta
anti-inflammatory
CMV tx
(val)ganciclovir, foscarnet, cidofovir
CD28
- co-stimulatory T cell protein that binds APC B7 (CD80/86)
- inhibited by CTLA-4
norovirus dx
PCR
TMP-SMX class
DHFR inhibitor
rhinovirus dx
PCR
fluconazole class
azole
nematode
roundworm
human metapneumovirus dx
RT-PCR
cestode
tapeworm (echinococcus)
caspofungin class
echinocandin
trematode
flatworm/fluke (schistosoma)
CD8
cytotoxic T cells
CD4
helper T cells
IL-17
- promotes neutrophils
- produced by Th17 cells
IFN-gamma
- stimulates macrophages
- increases MHC class I and II expression
- promotes Th1 and inhibits Th2
which is more severe: T. b. rhodiense (East African) or T. b. gambiense (West African?
gambiense => meningencephalitis
rhodiense => fever, headache, lymphadenopathy
IL-10
anti-inflammatory
HHV-8 tx
in vitro susceptibility to GCV, foscarnet, and cidofovir but none are effective
CD3
T cells
IL-2
promotes T cells growth and activation; autocrine function
IL-5
- differentiation/activation of eosinophils
- IgA class switching
RSV dx
antigen detection, RT-PCR
IL-1
pro-inflammatory, pyrogen
terbinafine class
allylamine
IL-6
pro-inflammatory, pyrogen
CD20
B cells; target of rituximab
CD40L
- expressed on T cells after activation
- binds CD40 on B cells/APCs
echinocandins
- antifungal
- inhibit cell wall glucan synthesis and impair cell wall stress tolerance
- ex = caspofungin
IL-12
- T cell growth factor
- Stimulates Th1
african sleeping sickness dx
trypomastigotes in blood smear or CSF
schistosoma life cycle (basic)
cercarieae in fresh water penetrate skin => travel upstream through portal circulation in liver => adults migrate to bowel/bladder to lay eggs => excretion of eggs into water through feces/urine => eggs hatch and penetrate snails where they develop into cercariae again
RSV tx
palivizumab prophylaxis, nebulized hypertonic saline
malaria dx
- history
- rapid antigen testing
- blood smear
amphotericin B/nystatin class
polyene
polyenes
- antifungal
- bind ergosterol and disrupt cell membrane
- ex = amphotericin B, nystatin
CMV dx
Owl’s eye inclusions, qPCR
cytokines produced in malaria infection
TNF, IFN-gamma, IL-1
influenza virus dx
rapid antigen test, RT-PCR
