Background: Neuropsin (NP, kallikrein 8, KLK8) - a kallikrein gene-related (KLK) endoprotease - plays a key role in neuroplasticity processes, since intracellular signal cascades and regulation of gene expression are engaged in long-term synaptic plasticity. The main aim of this paper is to compare expression of the human neuropsin gene on the mRNA level in a group of patients diagnosed with depression and in a group of healthy subjects who have never been treated psychiatrically.
Subjects And Methods: 291 people, aged 18-67, were qualified to participate in the experiment: major recurrent depression group (MRD) and the control group (CG).

The cytokine theory of depression no longer brings about any doubts. Experiments and research studies conducted in the last ten years have confirmed that both physical and psychological (emotional) stress increases the likelihood of occurrence of mental disorders (including depressive disorders) owing to the action of a series of hormonal and biochemical mechanisms. Selective serotonin reuptake inhibitors (SSRI) as well as serotonin and norepinephrine reuptake inhibitors (SNRIs) are some of the most commonly applied drugs in the world during pharmacotherapy of recurrent depressive disorder.

Background: A recurrent depressive disorder is one of the most commonly diagnosed disease entities among psychiatric disorders. The prevalence and morbidity of depression are constantly increasing. Numerous studies have demonstrated the role of genetic factors in the etiology of depressive disorders.

As an object of our analysis we have selected the miRNAs which - due to the profile of their activity - may be significant in the aetiology and course of recurrent depressive disorders, i.e.

According to the authors for clinical practice, both psychiatric and psychological, it is also important to effectively differentiate between these disease entities. The aim of this study is to compare the implementation of the Trail Making Test (TMT) in patients diagnosed with depressive disorders and those with organic depressive disorders.
