LAMB2 and amyotrophic lateral sclerosis: These observations were supported by significant (p = 0.001) decreases of capillary pericyte and laminin immunoexpressions in media-treated ALS mice (pericyte: 2.96 ± 0.13%; laminin: 1.99 ± 0.08%) versus controls (pericyte: 8.36 ± 0.26%; laminin: 9.14 ± 0.14%; Fig. 3B).
