Interleukin-1 β Modulates Melatonin Secretion in Ovine Pineal Gland: Ex Vivo Study

Figure 2

The effects of norepinephrine (NE, 10 μM), interleukin- (IL-) 1β (75 pg/mL), and mixture of NE with IL-1β on arylalkylamine-N-acetyltransferase (AA-NAT) relative gene (a) and protein (b) expression (mean ± SEM) in the pineal gland explants collected from saline- and lipopolysaccharide- (LPS-) treated ewes. Different lowercase letters indicate significant () differences within the saline-treated group; different capital letters indicate differences within the LPS-treated group.
