Mapping brain circuits and studying the neural signals that are activated during post-traumatic stress could provide an answer to the generalized fear associated with this disorder. Scientists at the University of California, San Diego have identified a change in the expression of neurotransmitters as an adaptive response that could trigger this effect.
Xgene Pharmaceutical Pty Ltd., a subsidiary of Xgene Pharmaceutical Co. Ltd., has received approval in Australia to initiate a phase I trial of the selective TRPM8 blocker XG-2002 (RQ-00434739).
Genzyme Corp. (dba Sanofi Genzyme) has disclosed isoxazolidine compounds acting as receptor-interacting serine/threonine-protein kinase 1 (RIPK1; RIP-1) inhibitors reported to be useful for the treatment of Alzheimer’s disease and multiple sclerosis, among others.
Alterations in mitochondrial dynamics are hallmarks of Parkinson’s disease (PD) and other neurodegenerative disorders such as Alzheimer’s disease (AD).
Sangamo Therapeutics Inc. has reported data from nonhuman primate (NHP) studies showing the potential of its proprietary AAV capsid variant, STAC-BBB, as a neurotropic capsid when administered intravenously at clinically relevant doses. STAC-BBB outperformed results for other evaluated neurotropic capsid variants.
Advances in understanding the processes underlying brain neurodegeneration have allowed lots of new treatment and prevention strategies to begin to flourish. Several presentations at the 2024 Alzheimer’s & Parkinson’s Diseases Conference recently held in Lisbon reflect that eyes are now on some individuals who, despite showing pathological signs in their brains, stay cognitively healthy across several endogenous mechanisms of resilience.
Agenebio Inc. has identified benzodiazepine derivatives acting as GABA(A) receptor subunits α5β3γ2 (GABRA5) positive allosteric modulators reported to be useful for the treatment of mild cognitive impairment, amyotrophic lateral sclerosis, schizophrenia, post-traumatic stress, autism, substance abuse and dependence, Alzheimer’s disease and Parkinson’s disease, among others.
In a new study, researchers from Harvard Medical School and Regulus Therapeutics Inc. further investigated the role of miR-155 in Alzheimer's disease (AD).
The activation of the NLRP3 inflammasome exacerbates neuronal dysfunction in several neurological diseases such as Alzheimer’s and Parkinson’s diseases, as well as multiple sclerosis. Targeting NLRP3 is an approach to overcome brain inflammation, among others.
In cell and animal models of amyotrophic lateral sclerosis (ALS), the expression of toxic dipeptides in neurons led to changes in the extracellular matrix (ECM) as a protective response. The authors wrote that their findings, which appeared in Nature Neuroscience on Feb. 29, 2024, could suggest new strategies for how to approach ALS.
