Nelle donne che soffrono di anoressia è stata riscontrata un'elevata percentuale di una molecola, non ancora ben identificata, che sembra agire sui meccanismi che regolano l’appetito.

Lo rivela una ricerca realizzata di alcuni medici inglesi dell’Imperial College di Londra che è stata presentata nel corso del meeting annuale della British Endocrine Societies a Glasgow.
Secondo i ricercatori la molecola sospetta, un peptide che è stato battezzato CART, potrebbe aiutare a definire una nuova strada terapeutica per combattere non solo l’anoressia, ma anche l’obesità .

"Nel sangue delle donne anoressiche - ha detto una delle autrici della ricerca, Sarah Stanley - abbiamo registrato livelli fino al 50 per cento superiori di questa molecola rispetto alle donne che invece non sogffrono di alcun disturbo alimentare".

Tuttavia il ruolo di questa molecola non è ancora chiaro "Noi conosciamo ancora poco del suo funzionamento - ha spiegato Stanley -. Non sappiamo , per esempio, se la CART è la causa della perdita di peso o il suo risultato".
