Figure 3a: Expression of Mella receptor in Teff cells. Differential expression was noted in Mella receptor expression following melatonin and catecholamine (NE, E, DA) (being significantly high with the treatment of (E) epinephrine. No of experiments=5; Teff Mella *P<0.05; **P<0.01; P<0.001 vs. Rest; ##P<0.01; ###P<0.001 vs. Activated; ^^^P<0.001 vs. Mel 10-7. Each histogram represents +SEM. No of experiments=5. (Teffs: Teffector; MEL: Melatonin, (NE: Nor Epinephrine; E: Epinephrine; DA: Dopamine).
