Input: Consider Input:  To increase the number of circulating polymorphonuclear neutrophils , the patient was treated with recombinant granulocyte - macrophage colony - stimulating factor ( GM - CSF ) at a dose of 2 micrograms protein / kg bodyweight s . c . / 12 h .

Output: GM - CSF


Input: Consider Input:  Presently , we made chain pair switch , chimeric , and site mutant gamma delta TCRs and transfected them into TCR - mutant Jurkat T cells to examine the effects of changing the TCR gamma junctional region sequences on reactivity to prenyl pyrophosphate Ags .

Output: prenyl pyrophosphate Ags


Input: Consider Input:  Strains carrying a snf1 mutation are unable to grow on sucrose , galactose , maltose , melibiose , or nonfermentable carbon sources ; utilization of these carbon sources is regulated by glucose repression .


Output: snf1 mutation
