A new cytokine: the possible effect pathway of methionine enkephalin

Table 2 Antagonism of different of concentrations of monoclonal antibody (MAb) to methionine enkephalin (MENK) at 1 × 10^-6 mol·L^-1 on the intracellular activity of PKC in NS-1 cells. n = 3 from 3 independent experiments. ^bP < 0.05 vs control, ^eP < 0.05 and ^fP < 0.05 vs group 2

Control	3.06 ± 0.19
MENK	2.26 ± 0.03b
MENK+10-11 mol·L-1 MAb	2.92 ± 0.02e
MENK+10-10 mol·L-1 MAb	2.80 ± 0.4e
MENK+10-9 mol·L-1 MAb	3.13 ± 0.45ff
