Amyotrophic lateral sclerosis (ALS) is a fatal disease characterized by the death of motor neurons in conjunction with neuroinflammation and deposition of protein aggregates, such as TDP-43, in these neurons and oligodendrocytes. Progranulin is a growth factor that is essential for neuron survival and a regulator of anti-inflammatory responses.
At the 2024 Alzheimer’s & Parkinson’s Diseases Conference this week, Michel Goedert from the MRC Laboratory of Molecular Biology in Cambridge gave the Donald L. Price Memorial Plenary Lecture entitled, “Cryo-EM structures of disease filaments from human brains.” Donald Price was particularly well-known for his work on plaques and tangles in nonhuman aged primate brains and for the development of several animal models of neurodegenerative diseases.
Charcot-Marie-Tooth (CMT) disease is a common neuropathy affecting the peripheral nerves. Compared to Type I, type 2 CMT presents as a slower and more progressive disease tied to axonal dysfunction, accompanied by distal muscle weakness and atrophy, sensory loss and reduced nerve conduction velocity, among others.
China State Institute of Pharmaceutical Industry and Jiangsu Nhwa Pharmaceutical Co. Ltd. have jointly described aromatic heterocyclic cyclohexyl aminoalkyl piperidine derivatives acting as serotonin 5-HT1A and/or dopamine D2 and/or D3 receptor agonists reported to be useful for the treatment of Parkinson’s disease.
The long-term use of corticosteroids for treating Duchenne muscular dystrophy (DMD) is tied to several undesired effects, compromising the patient’s quality of life; hence, the use of nonsteroidal drugs is highly desirable in the treatment of DMD. Metriopharm AG is investigating the nonsteroidal drug MP-1032 for DMD and recently presented data from studies in a model of DMD.
Iron-sulfur clusters are co-factors that are involved in several biological processes, such as oxidative phosphorylation, enzymatic reactions, and DNA replication and repair. Scientists from the National Institutes of Health (NIH) have presented a study regarding the clinical manifestations associated with a novel neuromuscular disease gene – CIAO1 – which encodes probable cytosolic iron-sulfur protein assembly protein CIAO1 and is an essential member in the cytoplasmic iron-sulfur assembly machinery.
On March 4, 2024, several groups of scientists discussed the challenges of investigating the effects of HIV in the central nervous system (CNS) at the oral abstract session on neuropathogenesis of HIV held during the 31st Conference on Retroviruses and Opportunistic Infections (CROI), in Denver. A cure for HIV will require eliminating the virus in all its reservoirs, those tissues where HIV remains latent but retains the capacity for reactivation and replication. However, despite antiretroviral therapy (ART), the virus could continue to replicate continuously at a low level in some reservoirs, including the CNS.
Suzhou Lexbio Pharm Co. Ltd. has patented macrocyclic triazole derivatives acting as high-affinity nerve growth factor receptor (NTRK1; TRKA) inhibitors reported to be useful for the treatment of cancer, multiple sclerosis, neuropathic pain, Alzheimer’s and Parkinson’s diseases.
A male patient who harbored a deletion in the intron 7-exon 8 region of the dystrophin gene, DMD, was showing symptoms that matched with Becker muscular dystrophy.
