Special Issue Information

Dear Colleagues,

A large body of studies highlight that Alzheimer’s disease (AD), described as a complex neurodegenerative disorder with a multilayered nature leading to a progressive decline in cognitive function and irreversible neuronal loss, continues to present a significant and escalating challenge to global health. As the frequency of cases rises and conventional pharmaceutical treatments, which primarily alleviate symptoms and come with numerous side effects, continue to exhibit a high rate of ineffectiveness, there arises a pressing demand for alternative approaches. Despite extensive knowledge on the molecular basis of AD, advancements in developing therapies that truly modify the progression of the disease have proven to be elusive. The ability of the editing system tools, repurposing current therapeutics or utilizing multi-target-directed ligands, presents a promising opportunity to elucidate the fundamental mechanisms driving AD pathogenesis and to discover new therapeutic pathways. This strategy has the potential to facilitate the identification of target molecules and the development of innovative preclinical disease models, thus providing hopeful prospects for therapeutic intervention.

Authors are invited to submit original research and review articles highlighting recent findings in the pharmacotherapy of Alzheimer’s disease. These includes, but are not limited to, novel molecular mechanisms and potential therapeutic targets, developing or repurposing drugs with the ability to target multiple disease features or exploring the risks and benefits of cannabinoid-based drugs.

Despite decades of rigorous research and numerous clinical trials, Alzheimer’s disease (AD) stands as a notable healthcare challenge of this century, with effective therapeutic solutions remaining elusive. Recently, the endocannabinoid system (ECS) has emerged as an essential therapeutic target due to its regulatory role in different physiological processes, such as neuroprotection, modulation of inflammation, and synaptic plasticity. This aligns with previous research showing that cannabinoid receptor ligands have the potential to trigger the functional structure of neuronal and brain networks, potentially impacting memory processing. Therefore, our study aims to assess the effects of prolonged, intermittent exposure (over 90 days) to JWH-133 (0.2 mg/kg) and an EU-GMP certified Cannabis sativa L. (Cannabixir® Medium Flos, 2.5 mg/kg) on recognition memory, as well as their influence on brain metabolism and modulation of the expanded endocannabinoid system in APP/PS1 mice. Chronic therapy with cannabinoid receptor ligands resulted in reduced anxiety-like behavior and partially reversed the cognitive deficits. Additionally, a reduction was observed in both the number and size of Aβ plaque deposits, along with decreased cerebral glucose metabolism, as well as a decline in the expression of mTOR and CB2 receptors. Furthermore, the study revealed enlarged astrocytes and enhanced expression of M1 mAChR in mice subjected to cannabinoid treatment. Our findings highlight the pivotal involvement of the extended endocannabinoid system in cognitive decline and pathological aspects associated with AD, presenting essential preclinical evidence to support the continued exploration and assessment of cannabinoid receptor ligands for AD treatment.
