title: Amphiphile-induced erythrocyte shape change and simultaneous tetraethylammonium ion uptake.
abstract: Amphiphile-induced tetraethylammonium ion (TEA+) uptake into human erythrocytes was examined along with cell shape change. A TEA(+)-sensitive electrode was used to determine the amount of uptake. TEA+ was preferentially incorporated into erythrocytes when amphiphiles changed cell shape to an invaginated form. This was contrasted with the release of acetylcholinesterase outside cells which occurred markedly with the amphiphiles, causing the crenated form. It was suggested that the invagination of erythrocyte membrane stimulated the formation of vacuoles, in which TEA+ existing in an external medium was entrapped.
