IT IS IL-12


  #4

I guess it is IL 1 because IL 1 is produced by macrophages , ,,,, IL 12 I guess helps T Helper cells Subset 1 to differnetiate into Cytotoxic T cells and Macrophages which are activated by IL2 and Interferon gamma respectively.
But I am not sure , let me knwo the correct answer


  #5

I was wrong I guess it is IL 12, may be I will have to check it , it is so confusing.......... :shock:
but I think it is IL 12 :oops:
finally I will put my money on IL 12 :wink:


  #6

Think of it like this when you want to know about the interleukins!
"HOT T-Bone stEAk"
IL-1:fever(hot)
IL-2:stimulates Tcells
IL-3:stimulates Bone marrow
IL-4:stimulates IgE production
IL-5:stimulates IgA production
This is from the USMLE Step 1 First Aid


  #7

IL-1 is secreted by macrophages whereas IL-2 is secreted by helper T cells


  #8

yes it is IL 12. which stimulates TH1 cells to produce IL 2 and IFN alpha.


  #9

how do you recognize what is deficient in piogene infections, especially/ or infection with Str pneumoniae and Haemophilus


  #10

Low Ig M.

Steptococcus pneumoniae and Haemophilus have the polysaccharide capsule in common which is protecting them from phagocytosis.
In Wiskott-Aldrich syndrome,the patient has a deficient IgM response to infections with bacteria that have a polysaccharide capsule.


  #11

yes, i am agree with that explanation, polysaccharide is un antigen recognize only limphocyte b. But you can have a recurent infection with the same critter, in deficit in acting of neutrophil ( NADPH oxidase), no? I think is better to have un algorithm to judge, but i don't know it is correct. 1. CBC with complete formula
2. after that immunograme
probably i am tired and all it so confusing right know
i'll repeat this chapter tomorrow


  #12

No you are all wrong it is Luke son of Darth Vador King of darkness master of evil loverof all death :evil:


  #13

Yes you are correct but i like to think of this anology

Ex-Lax
1) drink goes down smooth :wink:
2) Instant releif :P
3) an hoiur Later firey hell flowing from pooper :cry: :roll:


  #14

cytokine-- IL12
major source- Macrophage
major target cells-- helper t cell (Th1) and NK cell
major effect-- activation
:wink:


  #15

cytokine-- IL12
major source- Macrophage
major target cells-- helper t cell (Th1) and NK cell
major effect-- activation
