[ 11 C] BU99008 PET [ 11 C] BU99008 was developed as a PET tracer with high affinity and reversible binding to imidazol I 2 BS localized in the outer mitochondrial membranes and expressed mainly in astrocytes, with lower neuronal presence 361

S7).It is possible that, on human NK cells, although IGF-2 can exert its effects by binding to the IGF-2R, IGF-2 may also bind to the IGF-1R activating downstream effectors that are only partly similar to those induced by IGF-1
