Frequent concomitant manifestation of type 2 diabetes
mellitus (T2DM) and Alzheimer’s disease (AD) has
been recently demonstrated by epidemiological studies.
This might be due to functional similarities between
β-cells and neurons, such as secretion on demand of
highly specific molecules in a tightly controlled fashion.
An additional
similarity represents the age-related
alteration of hyperphosphorylated tau in AD patients.
Similarly, alterations have been identified in β-cells of
T2DM patients. The islet amyloid polypeptide has been
associated with β-cell apoptosis. As a consequence of
increasing age, the accumulation of highly modified proteins
together with decreased regenerative potential
might lead to increasing rates of apoptosis. Moreover, reduction
of β-cell replication capabilities results in reduction
of β-cell mass in mammals, simultaneously with
impaired glucose tolerance. The new challenge is to
learn much more about age-related protein modifications.
This can lead to new treatment strategies for
reducing the incidence of T2DM and AD.
