Involvement of nigral oxytocin in locomotor activity: A behavioral, immunohistochemical and lesion study in male rats.

Angioni L, Cocco C, Ferri G, Argiolas A, Melis M, Sanna F (2016) Involvement of nigral oxytocin in locomotor activity: A behavioral, immunohistochemical and lesion study in male rats. Horm Behav 83:23-38. doi: 10.1016/j.yhbeh.2016.05.012

Summary: Oxytocin is well known for its hormonal role in lactation and parturition, but also exerts widespread actions in central nervous system. Previous experiments revealed the existence of a correlation between the changes in locomotor activity found in Oxytocin-SAP-treated rats and the extent of the changes in nigral TH and vesicular glutamate transporters immunoreactivity, provide support for a modulatory role of oxytocin on locomotor activity at the level of the substantia nigra. The day after a prior assessment of spontaneous locomotor activity, rats were randomly injected bilaterally with 0.3 μL of Oxytocin-SAP (Cat. #IT-46, 60 ng/μL/site), or with the same amount of Blank-SAP (Cat. #IT-21, 60 ng/μL/site) or with vehicle (0.3 μL/site of PBS, pH 7.4). Whether oxytocin may be considered as a target for controlling motor disturbances, as those occurring in Parkinson’s disease and/or in other motor disturbances related to basal ganglia dysfunctions, remains to be evaluated
