Similar to what has been observed in human PD retinas, the analysis of the (Thy-1)- hu-A30P- α-Syn transgenic mouse showed the expression of the α-SYN transgene in the inner retinal layers while phospho-α-Syn was found in INL cells, in the cell bodies of the GCL, and in neurites in the IPL (Veys et al., 2019). The gene discussed is THY1; the disease is Parkinson disease.
