they are samewhat's the difference between IL-1 and IL_1??
I guess it it is GM-CSF
Fever and chills, so most probably neutropenia..
ok i got it later , infact i was confusing its mechanism with MTX that is DHF inhibitor (MTX will dec activation of the folic acid thats way we give leucoverin, already activated for of folic acid )but 5-FU is a thyamidylate synthase inhibitor dont reduce the activated form ,so answer is GM CSF , you are right ,
