Using our new and previously generated pSer129 αS antibodies and the new pSer473 NFL antibody 4F8, we performed IHC analyses on a cohort of mouse tissue derived from αS transgenic and WT mice (Table 2) and human autopsy cases with a diagnosis of PD, DLB or MSA (Table 3). The gene discussed is NEFL; the disease is Lewy body dementia.
