Fig 4. Hypothalamic TH and oxytocin neurons expressing the α4 nicotinic subunit.

Fig 4

A. 50.1% of TH-containing neurons in the A13 were colocalized with α4 (A1,2) while 50.7% of A12 TH-containing neurons in the arcuate nucleus showed α4 nAChR co-expression (A1,A2) (α4-TH, n = 3). There was no difference in colocalization across the different arcuate subdivisions analyzed (A2). B. Within the PVH, 41.3% of oxytocin neurons were also immunolabeled for α4 (α4-oxy, n = 4). Abbreviations: TH, tyrosine hydroxylase; Oxy, oxytocin; PVH, paraventricular nucleus of the hypothalamus; Arc, Arcuate nucleus; 3V, third ventricle. Scale bar: 200 μm.
