Article Abstract

Hypomyelinating leukodystrophies (HLD) are a group of heterogeneous genetic disorders characterized by a deficit in myelin deposition during brain development. Specifically, 4H-Leukodystrophy is a recessive disease due to biallelic mutations in the POLR3A gene, which encodes one of the subunits forming the catalytic core of RNA polymerase III (PolIII). The disease also presents non-neurological signs such as hypodontia and hypogonadotropic hypogonadism. Here, we report the generation of a human induced pluripotent stem cell (hiPSC) line from fibroblasts of the first identified carrier of the biallelic POLR3A variants c.1802 T > A and c.4072G > A.

Phosphodiesterase 9 (PDE9) is an enzyme that hydrolyzes cyclic guanosine monophosphate (cGMP)-a second messenger that regulates neuronal plasticity and memory function. PDE9 inhibition has been shown to enhance cognitive function in rodents, underlining the potential of PDE9 inhibitors (PDE9Is) as novel therapeutics for cognitive dysfunction. Considering the critical role of nitric oxide (NO)-cGMP signaling cascade in acetylcholine (ACh) release, the combination of PDE9Is and acetylcholinesterase inhibitors may synergistically elevate ACh levels in the brain.

Cardiovascular disease (CVD) is a leading cause of death worldwide. CVD includes conditions such as myocardial infarction (MI), arrhythmias, valvular heart disease, and cardiomyopathy. The limitations of heart treatment are related to the inability of damaged cells to regenerate, which leads to an increasing demand for new therapies.

Enterovirus D68 (EV-D68) is an emerging respiratory virus associated with extra-respiratory complications, especially acute flaccid myelitis. However, the pathogenesis of acute flaccid myelitis is not fully understood. It is hypothesised that through infection of skeletal muscles, the virus further infects motor neurons via the neuromuscular junction.

Amino acid (AA) detection is fundamental for cellular function, balancing translation demands, biochemical pathways, and signaling networks. Although the GCN2 and mTORC1 pathways are known to regulate AA sensing, the global cellular response to AA deprivation remains poorly understood, particularly in non-transformed cells, which may exhibit distinct adaptive strategies compared with cancer cells. Here, we employed murine pluripotent embryonic stem (ES) cells as a model system to dissect responses to AA stress.
