Appearance of antidepressant-like effect by sildenafil in rats after central muscarinic receptor blockade: evidence from behavioural and neuro-receptor studies
(Springer, 2008)The phosphodiesterase (PDE) 5 inhibitor sildenafil has been shown to display psychotropic actions in humans and animals, and has been used for the treatment of antidepressant-associated erectile dysfunction. However, its ... -
Azure B and a synthetic structural analogue of methylene blue, ethylthioninium chloride, present with antidepressant-like properties
(Elsevier, 2014)Aims: The phenothiazinium compound, methylene blue (MB), possesses diverse pharmacological actions and is attracting attention for the treatment of bipolar disorder and Alzheimer's disease. MB acts on both monoamine oxidase ... -
Azure B, a metabolite of methylene blue, is a high-potency, reversible inhibitor of monoamine oxidase
(Elsevier, 2012)Methylene blue (MB) has been shown to act at multiple cellular and molecular targets and as a result possesses diverse medical applications. Among these is a high potency reversible inhibition of monoamine oxidase A ... -
Chronic mild stress induces anhedonic behavior and changes in glutamate release, BDNF trafficking and dendrite morphology only in stress vulnerable rats. The rapid restorative action of ketamine
(Elsevier, 2019)Depression is a debilitating mental disease, characterized by persistent low mood and anhedonia. Stress represents a major environmental risk factor for depression; the complex interaction of stress with genetic factors ... -
Exploring a post-traumatic stress disorder paradigm in Flinders sensitive line rats to model treatment-resistant depression. I. Bio-behavioural validation and response to imipramine
(Cambridge Univ Press, 2017)Co-morbid depression with post-traumatic stress disorder (PTSD) is often treatment resistant. In developing a preclinical model of treatment-resistant depression (TRD), we combined animal models of depression and PTSD to ... -
The expression of plasticity-related genes in an acute model of stress is modulated by chronic desipramine in a time-dependent manner within medial prefrontal cortex
(Elsevier, 2017)It is well established that stress plays a major role in the pathogenesis of neuropsychiatric diseases. Stress-induced alteration of synaptic plasticity has been hypothesized to underlie the morphological changes observed ... -
Investigating the role of protein kinase-G in the antidepressant-like response of sildenafil in combination with muscarinic acetylcholine receptor antagonism
(Elsevier, 2010)The cGMP/PK-G pathway plays a crucial role in neuroprotection and neurotrophin support, and is possibly involved in antidepressant action. Recently we reported on a novel antidepressant-like response following simultaneous ... -
Is major depressive disorder a metabolic encephalopathy?
(Wiley, 2008)Metabolic encephalopathy is an acute disturbance in cellular metabolism in the brain evoked by conditions of hypoxia, hypoglycaemia, oxidative stress and/or inflammation. It usually develops acutely or subacutely and is ... -
Ketamine and rapidly acting antidepressants: breaking the speed of sound or light?
(Sage, 2018)There is an urgent need for rapidly acting antidepressants. Current therapies share a delayed onset of action, contrasting with drugs of abuse that have rapid psychotropic effects but cause tolerance and dependence. A key ... -
Neurovascular plasticity of the hippocampus one week after a single dose of ketamine in genetic rat model of depression
(Wiley, 2016)Glutamatergic system and the structural plasticity hypothesis are principal components for rapid and sustained antidepressant effects of novel antidepressant therapeutics. This study represents the first investigation of ...
