Ornithine 142-151 interleukin 4 Mus musculus 170-174 22865229-2 2012 IL-4-induced activation of macrophages produced arginase-1, which converts arginine into ornithine, a precursor of polyamines and proline. Ornithine 89-98 interleukin 4 Mus musculus 0-4 15638127-13 2004 High levels of ornithine were induced only upon IL-4 activation. Ornithine 15-24 interleukin 4 Mus musculus 48-52
