Special Issue Information

Dear Colleagues,

Increasing evidence has been accumulating over the past years which supports a pivotal role for inflammation in the pathogenesis of several neurological diseases, even those classically regarded as purely “neurodegenerative”. Microglia, monocytes, astrocytes, and neurons have been shown to play major roles in AD-associated inflammation and recent studies have shown that the role of both T and B lymphocytes may be important too. Inflammatory changes also occur in the brains of Parkinson's disease patients and these aspects are becoming matters of intense research. The immune response has also been involved in the pathogenesis of amyotrophic lateral sclerosis and fronto-temporal dementia.

The importance of the immune response in the pathogenesis of these diseases is highlighted by the number of molecules involved in inflammation which are associated with an increased risk of neurodegenerative disease in genome-wide association studies.

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. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.

This review analyzes the role of TNF-α and its increase in biological fluids in mild cognitive impairment, and Alzheimer’s disease (AD). The potential inhibition of TNF-α with pharmacological strategies paves the way for preventing AD and improving cognitive function in people at risk for dementia. We conducted a narrative review to characterize the evidence in relation to the involvement of TNF-α in AD and its possible therapeutic inhibition. Several studies report that patients with RA and systemic inflammatory diseases treated with TNF-α blocking agents reduce the probability of emerging dementia compared with the general population. Animal model studies also showed interesting results and are discussed. An increasing amount of basic scientific data and clinical studies underscore the importance of inflammatory processes and subsequent glial activation in the pathogenesis of AD. TNF-α targeted therapy is a biologically plausible approach for cognition preservation and further trials are necessary to investigate the potential benefits of therapy in populations at risk of developing AD.
