Calbindin, a decisive factor in differential susceptibility of mice strains to MPTP.
Fewer calbindin expressing neurons in substantia nigra of C57BL/6 than CD-1 mice.
Individual SNpc neuronal calbindin levels of CD-1 mice are higher than C57BL/6 mice.
Sizeable proportion of CD-1 dopaminergic neurons express higher levels of calbindin.
Higher protein expression in VTA, medial and dorsal nigra hint at regional resilience.
