"Discussion
The OB has been hypothesized to be one potential starting point for alpha-synuclein pathology and, thus the synucleinopathy disease process1,11. This contention is supported by several observations, including (1) mitral cell loss in PD OB2,5,18,32, (2) high incidence of LP in synucleinopathy OB3,5,33,34,35, and (3) incidental LP in OB3. Our inadvertent observation of PSER129 (which is usually associated with disease) in healthy mitral cells seems to support this hypothesis. "
