LA PRESENZA DI UNA PROTEINA CONTRATTILE MIOSINO-SIMILE A LIVELLO DEL TRABECOLATO CORNEO-SCLERALE DI CANE E DI UOMO (On the presence of a contractile myosin-like protein at the level of the trabecular menswork of dog and man)

Many data of the literature on the argument allow us to presume that the structures of the trabecular meshwork actively partecipate to the complex process of the aqueous outflow. We have considered that the microfilaments present into the cytoplasm of the endotelial cells lining the trabeculae and the inner wall of the canal of Schlemm are very similar to those observed into cells with contractile activity. By means of an hysthochemical technique that uses antimyosin antibodies (AMA) it has been possible to show the presence of a contractile miosin-like protein into the trabeculae (endotelial cells), at the level of the corneal endotelium and of the collector channels. This protein was present in specimens obtained both in dog and in man. Some considerations on the importance of such a results are advanced.
