ABSTRACT: Chronic psychosocial stress at workplace is an important factor in the development of physical and mental illness. Objective biological measures of chronic stress are still lacking, but inflammatory response and growth factors are increasingly considered as potential stress biomarkers. Therefore, we investigated the relationship between psychophysical strain and serum levels of 48 chemokines, cytokines and growth factors measured using a multiplex immunoassay, and serum brain-derived neurotrophic factor (BDNF) measured by ELISA. Severity of psychophysical strain was scored in 115 healthy hospital workers using specific scales for anxiety, depression-like emotion, gastrointestinal or cardiac disturbances, and ergonomic dysfunction. Multivariate analysis revealed that higher anxiety scale scores were correlated with lower serum chemokine C-C motif ligand-2 (CCL2/MCP-1), chemokine C-C motif ligand-5 (CCL5/RANTES), chemokine C-C motif ligand-27 (CCL27/CTACK), chemokine C-C motif ligand-11 (CCL11/Eotaxin) and interleukin-6 (IL-6); gastrointestinal disturbances correlated with increased levels of interleukin-17 (IL-17) and reduced CCL11/Eotaxin, CCL27/CTACK and CCL2/MCP-1; while cardiac dysfunctions associate only to reduced CCL27/CTACK, and ergonomic dysfunction correlated with increased BDNF and reduced CCL11/Eotaxin and CCL5/RANTES. Thus, these 7 serum factors may provide a distinct signature for each different stress-related psychophysical outcome giving indications on individual vulnerabilities.

Project description:Pityriasis rubra pilaris (PRP) is a rare inflammatory skin disorder associated with significant patient morbidity. To further characterize the molecular landscape of PRP, we conducted a transcriptomic analysis of epidermis and dermis collected from patients with moderate-to-severe PRP compared to matched healthy controls, on no systemic therapy and then following 24 weeks of treatment with the IL17A inhibitor, ixekizumab. Patients with PRP not only experienced clinical improvements, but also correction of their cutaneous transcriptome dysregulation after therapy. Moreover, those who has >50% improvement in PASI score after treatment demonstrated distinct transcriptomic profiles when compared to those who failed to respond, despite the lack of a discernable phenotypic difference. Pathway enrichment was strongest among DEGs belonging to inflammatory processes for patients with PRP – in particular, enrichment of the Th17 immune response was seen both prior to and following treatment with IL17A inhibition. Positive regulation of natural killer cell chemotaxis was also seen pre- and post-treatment, however, the pathway’s odds of enrichment decreased following treatment in both epidermis and dermis. Additionally, negative regulation of IL-12 production was highly enriched following therapy, suggesting decreased activity of the Th1 axis. Several individual genes of interest similarly displayed marked differential expression by response status. In parallel with their overall normalization in gene expression, responders had a greater normalization toward healthy control skin than non-responders in the Th17 family genes IL17C, IL23A, CCL20, as well as IL36A and IL36F (implicated in pustular psoriasis), Phospholipase A2 group IVD, and the antimicrobial protein S100A7, all of which remained elevated in non-responders. Intriguingly, responders had higher baseline levels of IL17A and IL17F than non-responders. Whereas dermal IL17A/F levels improved in responders, epidermal expression remained high despite the clinical response to IL17A inhibition. In contrast, non-responder IL17A/F epidermal levels normalized and dermal levels were significantly suppressed compared to healthy controls, despite the lack of clinical improvement. This suggests alternative pathways such as specific targeting of IL17C or IL36 may be preferred in some subsets of PRP.
