Project description:ALS is a complex neurodegenerative disease influenced by genetic, epigenetic, and environmental factors, resulting in dysfunction in cellular and molecular pathways. The limited efficacy of current treatments highlights the need for combination therapies targeting multiple aspects of the disease. Niclosamide, an anthelminthic drug listed as an essential medicine, has been repurposed in clinical trials due to its anti-inflammatory and anti-fibrotic properties. Niclosamide can inhibit various molecular pathways (such as STAT3 and mTOR) that are dysregulated in ALS, suggesting its potential to disrupt these altered mechanisms associated with the pathology. Our recent findings have demonstrated that niclosamide can effectively inhibit inflammatory and fibrotic molecular pathways in ALS models. We administered niclosamide intraperitoneally to two transgenic murine models, FUS and SOD1-G93A mice, which replicate key pathologies and biological processes of ALS. The treatment was initiated at the onset of symptoms, and we assessed the progression of the disease by neurological scores, rotarod and grip tests, as well as monitoring survival. Additionally, we examined the effects of the treatment on spinal cord and muscle degeneration in the treated mice. In both models, the administration of niclosamide resulted in a slowdown of disease progression, an increase in survival rates, and an improvement in tissue pathology. This was characterized by a reduction in gliosis, motor neuron loss, muscle atrophy, and inflammatory markers. Based on these results, our findings demonstrate that niclosamide can impact multiple pathways involved in ALS. This multi-targeted approach leads to a slowdown in the progression of the disease, thereby positioning niclosamide as a promising candidate for repurposing in the treatment of ALS.

Project description:Importance: Amyotrophic lateral sclerosis demonstrated changes in peripheral immune cells and proteins. However, the relationship between comprehensive immune profiles and clinical progression remained unclear. Objective: To identify the immune cells and proteins related to amyotrophic lateral sclerosis progression rate. Design: This case-control study enrolled healthy volunteers and patients with amyotrophic lateral sclerosis from March 29, 2021, to October 31, 2022. Setting: Tokushima University Hospital and Takeda Pharmaceutical Company Limited in Japan. Participants: This study screened 46 subjects to enroll 30 patients with amyotrophic lateral sclerosis within 2 years from onset and 10 healthy volunteers. Patients with rapid and non-rapid amyotrophic lateral sclerosis were those with Revised Amyotrophic Lateral Sclerosis Functional Rating Scale decreases of ≥1.0/month and <1.0/month, respectively. Exposure(s): Peripheral blood samples were collected. Main Outcome(s) and Measure(s): The progression rate as assessed with the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale decrease/month and the immune cell and protein profiles via single-cell RNA sequencing and immunoproteomics. Results: Samples of 7 (mean [standard deviation] age: 69.8 [14.4] years; male, 3) and 23 (60.7 [10.8] years; male, 17) patients with rapid and non-rapid amyotrophic lateral sclerosis, respectively, and 10 healthy volunteers (63.6 [10.2] years; male, 7) were analyzed. The ratios of T helper 17/regulatory T cells, mature/naïve CD8 T cells, and mature/naïve natural killer cells were significantly higher in rapid than in non-rapid amyotrophic lateral sclerosis. The ratio of T helper 17/regulatory T cells was significantly correlated with the progression rate. The immunoproteomics identified killer cell lectin-like receptor D1, trefoil factor 2, keratin 19, interleukin-17A, YTH N6-methyladenosine RNA binding protein F3, and neutrophil cytosolic factor 2 as significantly elevated in rapid amyotrophic lateral sclerosis. Cell type frequency and protein expression, such as T helper 17 cell–interleukin-17A and mature CD8 T cell–killer cell lectin-like receptor D1, were significantly correlated. Conclusions and Relevance: The progression rate was related to the increase of T helper 17 cells versus regulatory T cells and titers of T helper 17 cell- and CD8 T cell-related immunoproteins in patients with amyotrophic lateral sclerosis. These results provide promising biomarkers and targets for amyotrophic lateral sclerosis disease-modifying therapies.
