Abstract:Alzheimer's disease (AD) is a neurodegenerative disease and the main form of
dementia, characterized by progressive cognitive decline and detrimental consequences
in both personal-family and global level. Within this narrative review, we provide recent
molecular aspects of Tau, a microtubule AD-associated protein, as well as amyloid beta,
involved in AD pathophysiology. Moreover, we provide additional emerging data from
basic research as well as clinical studies indicating an implicating role of gastrointestinal
microbiota (GI-M), including Helicobacter pylori infection (Hp-I), in AD pathophysiology.
Likewise, we identified through a molecular prism the current evidence of AD
pathogenesis as well as its linkage with GI-M and emphasizing the role of Hp-I. All in all,
additional large-scale studies are required for the further clarification of AD
pathophysiology and its connection with GI-M and Hp-I, so as novel therapies on
molecular basis become available.
