Abstract:

Objective  To observe the distribution of mesencephalic astrocyte derived neurotrophic factor (MANF) within the brain in human, mice and rats and the comparison across the species.     Methods  An immunohistochemical method  was applied to investigate the expression of MANF and to compare the differences among species in the brain of human specimens (n=5), mice (n=6), and rats (n=6).     Results  The expression of MANF varied in different brain regions in human, mice and rats. In human, in the cortex, the expression of MANF was the highest among all brain regions. In the subcortical areas or the nucleus, brainstem and cerebellum expression level of MANF were relatively lower. The distribution of MANF in mouse and rat brain were slightly different from that in human brain, but generally consistent.    Conclusion  The distribution pattern of MANF is similar across the species, however, within a species, MANF expression levels varies in different brain regions.
