    ..Amylin receptor antagonists may thus serve as potentially useful therapeutic agents in treatment of AD. ..

    ..Furthermore, the two peptides may share a common mechanism of action. The ability of an amylin antagonist to block the responses evoked by hAmylin and A beta may provide a novel therapeutic approach for Alzheimer's disease. ..

  7. Jhamandas J, MacTavish D. ?-Amyloid protein (A?) and human amylin regulation of apoptotic genes occurs through the amylin receptor. Apoptosis. 2012;17:37-47 pubmed publisher
    ..These data allow us to identify key elements in the A?-induced apoptosis that are blocked by antagonism of the amylin receptor and further support the potential for amylin receptor blockade as a potential therapeutic avenue in AD. ..

    ..Furthermore, MMP-9 appears to cleave soAβ into less toxic monomeric species. Given the key role of histamine in MMP-9 release, this neurotransmitter may serve as a potential therapeutic target for AD. ..
  9. Fu W, Patel A, Kimura R, Soudy R, Jhamandas J. Amylin Receptor: A Potential Therapeutic Target for Alzheimer's Disease. Trends Mol Med. 2017;23:709-720 pubmed publisher
    ..Here, by discussing available evidence, we posit that the amylin receptor could be considered a potential therapeutic target for AD, and present the rationale for using amylin receptor antagonists to treat this debilitating condition. ..
