Antibody Decreases TDP-43 Protein Accumulation Easing ALS Symptoms, Mouse Study Suggests

A potential therapy for amyotrophic lateral sclerosis (ALS) consisting of an antibody that reduces the abnormal accumulation of the TDP-43 protein improved cognitive and motor performance in mice, a study shows. The study, “Viral-mediated delivery of antibody targeting TAR DNA–binding protein 43 mitigates associated neuropathology,” was published in The…

Human-derived Antibody Against SOD1 Aggregates Improves ALS Symptoms in Mouse Model, Study Shows

A human-derived antibody that specifically binds to abnormal superoxide dismutase 1 (SOD1) improved the symptoms and delayed disease progression in a mouse model for amyotrophic lateral sclerosis (ALS), a study shows. The antibody, alpha-miSOD1, could be further developed as a candidate treatment for ALS caused by SOD1 misfolding. The study titled…

Disease Progression Has Significant Effect on Quality of Life of ALS Patients, Study Says

In addition to symptoms of depression, disease progression is one of the strongest influences on health-related quality of life in amyotrophic lateral sclerosis (ALS) patients, a study reports. According to the study, titled Disease progression impacts health-related quality of life in amyotrophic lateral sclerosis,” slower disease progression is linked to…
