LAMB2 and amyotrophic lateral sclerosis: Examination of fluorescence of these antigens revealed significant (p = 0.001) decreases of capillary pericyte and laminin immunoexpressions in media-treated ALS mice (pericyte: 3.35 ± 0.18%; laminin: 2.54 ± 0.11%) versus controls (pericyte: 8.16 ± 0.28%; laminin: 9.38 ± 0.15%; Fig. 2B).
