Special Issue Information

Dear Colleagues,

Although Alzheimer's disease (AD) and other dementias are being intensively investigated, there is not yet a drug that efficiently interferes with disease pathogenesis. Most cases of AD are sporadic and less than 5%, among them carrying mutations that affect beta amyloid, are early‐onset familial AD that occur before the age of 65 years. Unfortunately, thus far, most of the newly developed drugs for AD treatment have failed in clinical trials. There is an urgent need for new therapies for treating dementias, particularly AD. Otherwise, this disease will continue to attack 5% of people aged over 65 and more than 40% of those aged over 85. Genetic risk factors, such as the presence of ApoE4 or mutations in inflammatory markers, such as TREM2, have been shown to affect disease development and progress. However, preventive approaches, such as maintaining good health (e.g., reducing cardiovascular and metabolic risk factors, enhancing physical and mental activities), seem to have a major impact on reducing disease incidence and delaying its onset. Many research approaches may be suitable for combating dementias, such as identifying disease-causing compounds (toxins), finding new targets, developing new drugs (mono/multi-target) by drug screening or by drug design, cell or organelle therapy, and device development, as well as other creative and innovative unconventional approaches.

This Special Issue will be dedicated to gathering novel therapeutic approaches to treat Alzheimer's disease and other dementias. We welcome submissions, including original papers and reviews, on these essential topics.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

N-methyl-d-aspartate receptors (NMDARs) are the main class of ionotropic receptors for the excitatory neurotransmitter glutamate. They play a crucial role in the permeability of Ca2+ ions and excitatory neurotransmission in the brain. Being heteromeric receptors, they are composed of several subunits, including two obligatory GluN1 subunits (eight splice variants) and regulatory GluN2 (GluN2A~D) or GluN3 (GluN3A~B) subunits. Widely distributed in the brain, they regulate other neurotransmission systems and are therefore involved in essential functions such as synaptic transmission, learning and memory, plasticity, and excitotoxicity. The present review will detail the structure, composition, and localization of NMDARs, their role and regulation at the glutamatergic synapse, and their impact on cognitive processes and in neurodegenerative diseases (Alzheimer’s, Huntington’s, and Parkinson’s disease). The pharmacology of different NMDAR antagonists and their therapeutic potentialities will be presented. In particular, a focus will be given on fluoroethylnormemantine (FENM), an investigational drug with very promising development as a neuroprotective agent in Alzheimer’s disease, in complement to its reported efficacy as a tomography radiotracer for NMDARs and an anxiolytic drug in post-traumatic stress disorder.
