Hi, there, I am reading papers about a certain membrane protein.
This molecule is expressed in platelets.
To address the function of this molecule in platelets, they analyzed global KO mice's platelets.
Then, to see whether KO's phenotype is rescued by WT's platelet, they infused WT platelet into global KO mice.
Beautifully, WT platelets rescued KO mice's phenotypes.
I think these kinds of experiments are widely used in immunology field etc.
But this molecule is expressed in platelet's surface because of membrane protein.
So I am curious why in this case, infused platelets was NOT rejected by KO's immune system.
Because KO's immune system is immunologically naive to that molecule, so it is reasonable to imagine rejection to WT's platelets.
To infuse platelets, they did not irradiation on host.
So host's immune system should be functional.
Would you please give me your comments?
Sincerely,
bM |
