However , given that A beta 11 - 42 is converted to [ Pyr ( 11 ) ] A beta 11 - 42 by a glutamyl cyclase in vivo , the potential aggregative and cytotoxic nature of [ Pyr ( 11 ) ] A beta 11 - 42 that was observed in the present study provides valuable insights into the pathological functions of pyroglutamate - modified A beta species in Alzheimer ' s disease .
