“…Concomitantly, lithium elevates the concentration of circulatory TNF-α (Beyaert, Schulze-Osthoff, Roy, & Fiers, 1991;El-Twab & Abdul-Hamid, 2016;Matsebatlela, Gallicchio, & Becker, 2012). This elevation might be attributed to the activation of the extracellular signal-regulated kinase (ERK) pathway (Kim et al, 2012;Sung et al, 2019), mitogen-activated protein kinases (MAPK)-ERKdependent pathway (Hull et al, 2014), nuclear factor-kappa B (NF-κB)-independent pathway (Schotte, Loo, Carpentier, Vandenabeele, & Beyaert, 2001;Sung et al, 2019), protein kinase C (PKC) (Young, Wang, Woods, & Robb, 1999), CD4 helper T-cell/CD8 suppressor (Wahlin, Knorring, & Roos, 1984) or initiation of granulocytosis (Kleinerman, Knowles, Blick, & Zwelling, 1989). Thus, lithium stimulates TNF-mediated cytotoxicity (Gallicchio, Hughes, Tse, Ling, & Birch, 1995).…”
