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). The gene discussed is MT-CO2; the disease is amyotrophic lateral sclerosis.
