“…This view is supported by studies showing that PEA levels change in settings of tissue injury, especially in situations associated with inflammatory and neurodegenerative processes (Franklin et al, 2003 ; Petrosino et al, 2007 , 2010 ; Bisogno et al, 2008 ; Loría et al, 2008 ; Garcia-Ovejero et al, 2009 ; Iannotti et al, 2016 ; Petrosino and Di Marzo, 2017 ). This hypothesis is supported by a large body of evidence showing that the systemic administration of PEA elicits anti-inflammatory, antinociceptive, and neuroprotective effects, both in vivo and in vitro (Mazzari et al, 1996 ; Costa et al, 2008 ; Genovese et al, 2008 ; Esposito et al, 2011 ; D'Agostino et al, 2012 ; Esposito and Cuzzocrea, 2013 ; Abramo et al, 2017 ; Skaper, 2017 ; Scuderi et al, 2018 ), as well as in man (Truini et al, 2011 ; Gatti et al, 2012 ; Marini et al, 2012 ; Paladini et al, 2016 ; Artukoglu et al, 2017 ; Passavanti et al, 2017 ; Chirchiglia et al, 2018 ) and companion animals (Scarampella et al, 2001 ; Noli et al, 2015 ).…”
