We used immunofluorescence to evaluate the co-localization of lysosome-associated membrane glycoprotein 2 (LAMP2) and MTCO2 in NeuN-positive (NeuN+) neurons in the spinal ventral horn of ALS patients and gender-matched healthy controls from the Netherland brain bank (Table EV1). Here, LAMP2 is linked to amyotrophic lateral sclerosis.
