Polymerisation underlies alpha1-antitrypsin deficiency, dementia and other serpinopathies
We review here the molecular mechanisms that underlie α1-antitrypsin deficiency and show how an understanding of this mechanism has allowed us to explain the deficiency of other members of the serine proteinase inhibitor or serpin superfamily. These include the deficiency of antithrombin, C1-inhibitor and α1-antichymotrypsin in association with thrombosis, angio-oedema and emphysema respectively. Moreover the accumulation of mutant neuroserpin within neurones causes the novel dementia familial encephalopathy with neuroserpin inclusion bodies (FENIB). We have grouped these conditions together as the serpinopathies as recognition of their common pathophysiology provides a platform to develop strategies to treat the associated clinical syndromes.
