Abstract

Depression is a common mental disorder that affects millions of individuals worldwide. Available monoaminergic antidepressants are far from ideal since they show delayed onset of action and are ineffective in approximately 40% of patients, thus indicating the need of new and more effective drugs. ATP signaling through P2 receptors seems to play an important role in neuropathological mechanisms involved in depression, since their pharmacological or genetic inactivation induce antidepressant-like effects in the forced swimming test (FST). However, the mechanisms involved in these effects are not completely understood. The present work investigated monoamine involvement in the antidepressant-like effect induced by non-specific P2 receptor antagonist (PPADS) administration. First, the effects of combining sub-effective doses of PPADS with sub-effective doses of fluoxetine (FLX, selective serotonin reuptake inhibitor) or reboxetine (RBX, selective noradrenaline reuptake inhibitor) were investigated in mice submitted to FST. Significant antidepressant-like effect was observed when subeffective doses of PPADS was combined with subeffective doses of either FLX or RBX, with no significant locomotor changes. Next, the effects of depleting serotonin and noradrenaline levels, by means of PCPA (p-Chlorophenylalanine) or DSP-4 (N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine hydrochloride) pretreatment, respectively, was investigated. Both, PCPA and DSP-4 pretreatment partially attenuated PPADS-induced effects in FST, without inducing relevant locomotor changes. Our results suggest that the antidepressant-like effect of PPADS involves modulation of serotonin and noradrenaline levels in the brain.

  • The antidepressant-like effect in mice induced by systemic treatment with PPADS was blocked by 5-HT or NA depletion, implicating these monoamines in the drug effect.

    “In a recent study, it was shown that the antidepressant-like effect in mice induced by systemic treatment with PPADS (P2R inhibitor) was blocked by 5-HT or NA depletion, implicating these monoamines in the drug effect [96].”

  • Co-treatment with sub-effective doses of PPADS and serotonergic (fluoxetine) or noradrenergic (desipramine) antidepressants had synergistic effects.

    “Indeed, co-treatment with sub-effective doses of PPADS and serotonergic (fluoxetine) or noradrenergic (desipramine) antidepressants had synergistic effects [96].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
