The purpose of this article was to study the immunotropic effects of the new neurotrophic heptapeptide selank. The experiments in vitro revealed that the drug in concentration 10-7 M completely suppressed gene expression by peripheral blood IL-6 of patients with depression but not of the healthy controls. At the same time, the significant increase (p<0,05) of IL-6 concentration was observed in the cell culture of peripheral blood of patients in the presence of selank. The changes of the Th1/Th2 cytokine balance in vivo were found in the serum of patients with generalized anxiety disorder and neurasthenia who received Selank during 14 days. The dynamics of these changes had the significant inverse correlation dependence. The cytokine regulating effects revealed in the study suggest that selank can be used as a novel immunomodulator in patients with anxiety-asthenic disorders. Additionally, the adaptogenic properties of selank may be beneficial to its use in elderly people and people exposed to environmental stressors for the prevention of infectious diseases.

Background: Inflammation is a driver of thrombosis, but the phenomenon of thromboinflammation has been defined only recently, bringing together the multiple pathways involved. models can support the development of new therapeutics targeting the endothelium and also assess the existing immunomodulatory drugs, such as hydroxychloroquine, in modulating the inflammation-driven endothelial prothrombotic phenotype.
Objectives: To develop a model for thrombin generation (TG) on the surface of human endothelial cells (ECs) to assess pro/antithrombotic properties in response to inflammation.

Human milk oligosaccharides (HMOs) are abundant, diverse and complex sugars present in human breast milk. HMOs are well-characterized barriers to microbial infection and by modulating the human microbiome they are also thought to be nutritionally beneficial to the infant. The structural variety of over 200 HMOs, including neutral, fucosylated and sialylated forms, allows them to interact with the immune system in various ways.

Introduction: Crohn's disease (CD) is a chronic inflammatory condition of the intestines with a rising global incidence. Traditional diagnostic and therapeutic methods have limitations, necessitating the exploration of more effective strategies.
Methods: In this study, we employed the Gene Expression Omnibus database to identify genes that are differentially expressed in CD.
