Alzheimer's disease is an age-related neurodegenerative disorder with increasing prevalence. Current treatments are limited to symptomatic medication, and there is a need for a better understanding of the underlying mechanisms to develop more rational therapies. Peripheral inflammation has been identified as a detrimental factor in AD, and this review provides an overview of the link between peripheral inflammation and AD initiation and progression, contributing to a broader understanding of the disease pathology.
Alzheimer's disease (AD) is a devastating age-related neurodegenerative disorder with an alarming increasing prevalence. Except for the recently FDA-approved Aducanumab of which the therapeutic effect is not yet conclusively proven, only symptomatic medication that is effective for some AD patients is available. In order to be able to design more rational and effective treatments, our understanding of the mechanisms behind the pathogenesis and progression of AD urgently needs to be improved. Over the last years, it became increasingly clear that peripheral inflammation is one of the detrimental factors that can contribute to the disease. Here, we discuss the current understanding of how systemic and intestinal (referred to as the gut-brain axis) inflammatory processes may affect brain pathology, with a specific focus on AD. Moreover, we give a comprehensive overview of the different preclinical as well as clinical studies that link peripheral Inflammation to AD initiation and progression. Altogether, this review broadens our understanding of the mechanisms behind AD pathology and may help in the rational design of further research aiming to identify novel therapeutic targets.
