Research News

 
Researchers first turned to neurotrophic factors (NTFs) as a potential treatment strategy for ALS in the early 1990s in hopes to shield motor neurons from destruction. But the clinical translation of these approaches has proved challenging.  Now, a new study suggests that multiple factors may be needed to provide the most therapeutic benefit. The study, led by Georg Haase at the Aix-Marseille University in France, found that NTFs promote the survival of distinct classes of motor neurons in the lumbar spinal cord. The findings suggest that a combination of these neuroprotective substances may be needed to protect motor neurons affected by the disease.  The study appeared on March 16 in the Proceedings of the National Academy of Sciences .

The axon executioner SARM1 is an enzyme and therefore potentially druggable according to a new study published in March 16 in Neuron. The study, led by Washington University St Louis' Jeffrey Milbrandt in Missouri, found that SARM1 catalyzed the cleavage of NAD+, a key cofactor needed for ATP synthesis. Milbrandt's team previously demonstrated that SARM1 triggered axon degeneration by depleting its energy by reducing the availability of NAD+. The findings build on studies in 2012 led by Marc Freeman at the University of Massachusetts Medical School in Worcester which found that injured axons self destruct through a SARM1-mediated mechanism.

About 1-3% of cases of familial ALS are due to mutations in profilin, a key regulator of actin dynamics. How changes in the axonal cytoskeleton could contribute to ALS, however, remains unclear. Now, John Landers and colleagues at the University of Massachusetts in Worcester report that profilin may help keep muscle fibers and motor neurons connected by promoting the remodeling of neuromuscular junctions. The findings add to growing evidence that a reduction in axonal actin dynamics may contribute to ALS, including the most common form of the disease. The study is published on April 3 in Human Molecular Genetics.

 
An emerging biomarker may facilitate the development of potential therapies for C9orf72 ALS, according to a new study led by Mayo Clinic's Leonard Petrucelli in Florida. The study found that patient-derived motor neurons pre-treated with C9orf72 repeat RNA-targeted antisense oligonucleotides (ASOs) exhibited a dose-dependent drop in levels of the C9orf72 dipeptide repeat protein polyGP. What's more, the researchers saw a similar dose-dependent decrease in the C9orf72 ASO-treated brain of a mouse model of the disease. The approach is based on an antibody-based "sandwich" assay previously developed by the Petrucelli lab that rapidly detects polyGP in the CSF. The strategy may help scientists evaluate potential therapies for C9orf72 ALS in the clinic by enabling the monitoring of target engagement. The study is published on March 29 in Science Translational Medicine.

The inflammatory biomarker C-reactive protein (CRP) may help inform the outcomes of patients with ALS according to a study published on April 3 in JAMA Neurology. The study, led by NeuroMuscular Omnicentre's Christian Lunetta in Italy, found that circulating levels of CRP in the blood inversely correlated with functional impairment (ALS-FRS score) and survival (hazard ratio, 1.129; 95% CI, 1.033-1.234; P = .007). 394 patients with ALS participated. The results confirm that the measurement of this inflammatory substance in the blood may help clinicians prognose ALS by identifying patients with a high progression rate.  The approach, which involves a standard blood test which checks for inflammation, may also facilitate the evaluation of potential therapies for ALS by enabling the stratification of patients in clinical trials.

Read more about CRP, including its potential to identify "responders" to anti-inflammatory therapies being evaluated in the clinic including NP001.

 
Biomarkers are desperately needed to expedite the diagnosis and inform the prognosis of ALS. But how to prioritize the potential candidates identified to evaluate in the clinic has proved challenging. Now, using an unbiased data-driven approach that combines genomics with ALS pathology, Johnathan Cooper-Knock and colleagues at the University of Sheffield in England report that CSF soluble TREM2 may be a potential biomarker of ALS progression. Soluble TREM2, which is produced in microglia and may instigate inflammation, is also emerging as an early biomarker of Alzheimer's Disease. The study is published on March 16 in Acta Neuropathologica Communications.
