L'attività scientifica di L.A. ha affrontato problemi di biologia dello sviluppo e cellulare.
In particolare, le tematiche affrontate riguardano: a) l'immunologia comparata e dello sviluppo in Teleostei e Uccelli, b) l'anatomia, fisio-farmacologia e sviluppo dei neuroni sensitivi primari nei mammiferi, c) l'endocrinologia comparata in pesci e mammiferi.
Le ricerche condotte sul sistema immunitario dei pesci Teleostei, iniziate nei primi anni '90, sono oggi focalizzate nelle seguenti sottotematiche: sviluppo, meccanismi di trasferimento di anticorpi materni alle uova e agli embrioni, caratterizzazione funzionale e molecolare delle popolazioni linfocitarie, immunità mucosale, analisi morfo-funzionale e molecolare delle modulazioni neuro-immunitarie nell’intestino, immunità specifica in specie di allevamento intensivo: effetti di stress e integrazione dietetica con immunostimolanti o batteri probiotici, studio morfo-funzionale e molecolare degli adattamenti del sistema immunitario in condizioni ambientali estreme (teleostei antartici e teleostei mesopelagici).
Tali ricerche si avvalgono di consolidate collaborazioni con laboratori EU (Olanda, UK, Spagna), americani (Canada, USA) e nazionali (Università, CNR, ENEA, ICRAM, industria).
L.A. è co-autore di 85 articoli in extenso pubblicati da riviste scientifiche internazionali(IF totale >150; JCR-SCI), citati piu' di 1500 volte (fonte ISI), è membro di numerose società scientifiche e da 1997 membro fondatore della Società Italiana di Immunologia Comparata e dello Sviluppo.
