Special Issue Information

Dear Colleagues,

AD and diabetes are two age-related diseases, and some studies have shown patients with diabetes to have an increasing risk of developing AD compared with those without the disease. For example, type 2 diabetes (T2D) patients have been observed to have reduced grey matter, white matter, hippocampus, and whole-brain volumes compared with healthy individuals. Although impaired insulin signaling has been found to be a key component of AD pathology and a hallmark of diabetes, the mechanistic pathway that links these two diseases is still not fully understood.

This Special Issue will accept original articles and reviews in the field of neurodegenerative disease. It also welcomes studies investigating age-related diseases’ complex interactions, potential disease biomarkers, and novel drug therapies. Manuscripts focusing on noncoding RNAs in neurodegenerative disease and the underlying biological mechanisms are particularly sought-after.

Alzheimer’s disease (AD) is a neurodegenerative disorder that significantly impacts the lives of patients and their families. The pathological features of AD include the accumulation of amyloid-β (Aβ) and Tau, which disrupt neuronal function and communication, ultimately leading to neuronal loss and brain atrophy. Efforts to understand the molecular mechanisms underlying these pathological changes have led to advancements in diagnostic techniques and potential therapeutic interventions. However, the complexity of AD necessitates further research to develop more effective treatments and, ideally, preventive measures. Extensive research suggests that diminishing mTOR signaling increases lifespan and health span across various species. Increased PI3K/mTOR signaling has been linked to the progression of AD pathology, leading to neuronal degeneration and impairments in cognitive function. In this study, we explored the therapeutic potential of PF-04691502, a dual PI3K/mTOR inhibitor, in Alzheimer’s disease (AD)-like pathology using male and female B6.Cg-Tg(APPswe, PSEN1dE9)85Dbo/Mmjax mice (APP/PS1), a well-established transgenic model of AD. Eighteen-month-old APP/PS1 and wild-type mice received oral administration of PF-04691502 at a dose of 1 mg/kg for 12 weeks. Following the treatment period, spatial learning and memory were evaluated using the Morris water maze. Subsequently, the mice brains were collected for neuropathological and biochemical assessments. Our findings showed that PF-04691502 enhanced cognitive performance in APP/PS1 mice and significantly reduced insoluble Aβ accumulation in the brain. Mechanistically, these effects were associated with enhanced autophagy induction. Treatment with PF-04691502 increased the LC3-II/LC3-I ratio, upregulated Beclin-1, and elevated LAMP-2 levels, indicative of stimulated autophagosome formation and lysosomal activity. Overall, these preclinical results suggest that PF-04691502 holds promise as a potential therapeutic agent for AD and other aging-related neurodegenerative diseases involving mTOR pathway dysregulation.

This study evaluates the effects of hypergravity (HG) on a neurodegenerative model in vitro, looking at how HG influences Tau protein aggregation in Mouse Hippocampal Neuronal Cells (HT22) induced by neurofibrillary tangle seeds. Overall, 50× g significantly, synergistically, reduced the Tau aggregate Area when combined with ERK-inhibitor PD-0325901, correlating with decreased phosphorylation at critical residues pS262 and pS396. These findings suggest HG treatments may help mitigate cytoskeletal damage linked to Tau aggregation. Full article

Neurodegenerative diseases encompass a number of very heterogeneous disorders, primarily characterized by neuronal loss and a concomitant decline in neurological function. Examples of this type of clinical condition are Alzheimer’s Disease, Parkinson’s Disease, Huntington’s Disease and Amyotrophic Lateral Sclerosis. Age has been identified as a major risk in the etiology of these disorders, which explains their increased incidence in developed countries. Unfortunately, despite continued and intensive efforts, no cure has yet been found for any of these diseases; reliable markers that allow for an early diagnosis of the disease and the identification of key molecular events leading to disease onset and progression are lacking. Altered adult neurogenesis appears to precede the appearance of severe symptoms. Given the scarcity of human samples and the considerable differences with model species, increasingly complex human stem-cell-based models are being developed. These are shedding light on the molecular alterations that contribute to disease development, facilitating the identification of new clinical targets and providing a screening platform for the testing of candidate drugs. Moreover, the secretome and other promising features of these cell types are being explored, to use them as replacement cells of high plasticity or as co-adjuvant therapy in combinatorial treatments.
