The role of amylin in Alzheimer’s disease remains an open question. As
reviewed in this paper, numerous studies show that amylin can misfold and aggregate, and
can cause or exacerbate pathophysiological changes associated with AD [e.g., (Fu et al., 2012; Jhamandas et al., 2011; Jhamandas and Mactavish,
2012)]. However, other data indicate that exogenous administration of amylin
receptor agonists can ameliorate AD symptoms [e.g., (Adler
et al., 2014; Zhu et al., 2015; Zhu et al., 2017b)], suggesting that amylin-based
pharmacotherapies may be useful in the treatment of AD. There are currently several gaps
in the literature that limit our understanding of the effects of amylin in AD, a few of
which are represented in the gray diamonds.
