Neurodegenerative disease and cognitive decline cannot be explained by a single process. Beta-amyloid plaques, hyperphosphorylated tau, alpha-synuclein, activated microglia and astrocytes, altered receptors such as TREM2, mitochondrial dysfunction, epigenetic changes and cerebrovascular alterations all seem to contribute to the development of dementia in Alzheimer’s disease (AD). While scientists attempt to address each of these elements, prevention is growing as a primary goal.

Facioscapulohumeral muscular dystrophy (FSHD) is a muscle wasting disease caused by aberrant expression of double homeobox protein 4 (DUX4). When DUX4 is activated in skeletal muscle, it triggers myocyte cell death after several transcriptional changes, thus genetic DUX4 silencing arises as a promising approach for treating FHSD.

Entering a cell and watching its entire inner machinery at work, how DNA is copied, how proteins are assembled, or how it splits in two, has been, for decades, an impossible dream. Now, scientists at the University of Illinois have recreated everything that happens inside a cell at molecular scale in an unprecedented computational model. Syn3A is the first 4D digital cell, capable of combining time and space to simultaneously represent all the internal processes that drive the life cycle of a minimal prokaryotic organism.

Researchers from Chemicare Srl and the University of Piemonte Orientale have presented preclinical results regarding their (SOCE) negative regulator CIC-39. Researchers evaluated the dysregulation of SOCE in both ex vivo and in vivo models of Duchenne muscular dystrophy (DMD), as well as evaluated the therapeutic potential of CIC-39 in DMD.

GM1 gangliosidosis is a lysosomal storage disease caused by mutations in the human GLB1 gene, encoding the ubiquitous lysosomal β-galactosidase. GM1 causes a rapidly progressing neurodegeneration, which can be lethal in the first 2 years of life in the most severe cases.

Glucocerebrosidase (GCase), encoded by the gene GBA1, is a ubiquitous lysosomal enzyme that breaks down lipid substrates, glucosylceramide (GL-1) and glucosylsphingosine (Lyso-GL1), into glucose and ceramide. Loss-of-function mutations in GBA1 reduce GCase activity, resulting in lipid accumulation within lysosomes and subsequent lysosomal dysfunction.

A therapeutic strategy based on alternative splicing of the MECP2 gene could restore protein levels in Rett syndrome, a neurological disorder caused by mutations in that gene. Scientists at Baylor College of Medicine have successfully tested this approach both in vitro in neurons from Rett patients that produce some functional protein, correcting the altered gene expression and improving neuronal functions, and in vivo in mice.

Beam Therapeutics Inc. has added a new program to its liver-targeted genetic disease franchise, BEAM-304, for the treatment of phenylketonuria (PKU).
