Gut Region-Specific Interleukin 1β Induction in Different Myenteric Neuronal Subpopulations of Type 1 Diabetic Rats.

Interleukin 1β (IL1β) is a pro-inflammatory cytokine that may play a crucial role in enteric neuroinflammation in type 1 diabetes. Therefore, our goal is to evaluate the effects of chronic hyperglycemia and insulin treatment on IL1β immunoreactivity in myenteric neurons and their different subpopulations along the duodenum-ileum-colon axis. Fluorescent immunohistochemistry was used to count IL1β expressing neurons as well as the neuronal nitric oxide synthase (nNOS)- and calcitonin gene-related peptide (CGRP)-immunoreactive myenteric neurons within this group.

Change of Circulating Vascular Endothelial Growth Factor Level and Reduction of Anhedonia Are Associated in Patients With Major Depressive Disorder Treated With Repetitive Transcranial Magnetic Stimulation.

Aim: Vascular endothelial growth factor (VEGF) has been implicated in mediating the effect of antidepressant therapies as it plays a significant role in the neurogenesis. Anhedonia, an endophenotype of major depressive disorder (MDD), is related to the dorsolateral prefrontal cortex, the major focus of brain stimulation in MDD. The aim of our study was to analyze the change of serum VEGF level after rTMS treatment in association with anhedonia.

Peripheral endocannabinoid serum level in association with repetitive transcranial magnetic stimulation (rTMS) treatment in patients with major depressive disorder.

Repetitive transcranial magnetic stimulation (rTMS) is an effective and well tolerable biological intervention in major depressive disorder (MDD) contributing to rapid symptom improvement. Molecular mechanisms underpinning the therapeutic effects of rTMS have still not been clarified. Recently published animal data implicated relevant associations with changes in endocannabinoid (eCB) brain levels during rTMS treatment, human studies, however, have not been published.

[Investigation of the acute effect of bilateral repetitive transcranial magnetic stimulation (rTMS) in therapy resistant major depression patients].

Introduction: There is a 20-year history of rTMS treatment, however, is not available in Hungary in routine clinical practice for therapy resistant depression (TRD). In this study we analysed the change of symptom profile of a Hungarian cohort with TRD using bilateral rTMS treatment.

Methods: A cohort of 22 patients suffering from TRD was enrolled in the study.

[Vascular endothelial growth factor (VEGF) as a potential biomarker in major depressive disorder].

Background: There is growing evidence that vascular endothelial growth factor (VEGF) plays a crucial role in neurodevelopment and regeneration. Several data support that intact VEGF pathway is indispensable for therapeutic effect of antidepressants, any disruption of VEGF signaling can result treatment resistance. In our study we investigated the peripherial blood VEGF level before and 4-week after antidepressant treatment in patients with major depressive episode and we compared VEGF levels between responders and non-responders.
