Article Synopsis
- The "Promoting Responsible Research and Innovation" (RRI) initiative, part of the EU Horizon 2020 program, aligns research with societal values through public engagement, open access, and ethics, involving 6 European and 6 international institutions.
- The STARBIOS2 project aims to foster structural change in RRI at participating institutions by implementing action plans and creating guidelines for biosciences research.
- The project is structured around 6 core and 5 supporting work packages, focusing on institutional changes, technical assistance, and monitoring, and will run for four years with funding from Horizon 2020.
Objective: Therapeutic options for the tuberous sclerosis complex (TSC) syndrome showed varying outcomes. Malfunctional tsc1/tsc2 genes leave mTOR uninhibited, a positive downstream modulator of the innate proinflammatory immune system, which has not yet been described in pediatric patients with TSC.
Methods: Using polymerase chain reaction (PCR) gene expression levels of monocytes after cultivation with lipopolysaccharide (LPS) or with LPS + mTOR inhibitor rapamycin, patients with TSC (n = 16) were compared with healthy subjects (n = 20).
Background: Interleukin-27 (IL-27) has been described to be highly expressed during the very first days after birth, but secretion of IL-27 by dendritic cells during the course of childhood has not been described.
Findings: In our present study we enrolled children (n = 55) in the range from 1 day of to 18 years of age and asked for a small whole blood sample. The capacity of dendritic cells to produce IL-27 during childhood was measured after whole blood culture with or without inflammatory stimuli.
Interleukin (IL)-27 is known to be increased considerably in cord blood (CB) dendritic cells (DCs) after TLR ligation. Previously, we demonstrated that also basal IL-27 levels are higher in CB DCs. Here, we examined effects of IL-27 on monocyte derived dendritic cells (moDCs) to approach its particular role in the specialized immune system of the human neonate.

As a pleiotropic cytokine, IL-21 acts on both innate and adaptive immune responses, suggesting that IL-21 may be a master regulator of the T-cell-dependent adaptive immune response. Although IL-21 is described as mostly promoting inflammation, evidence also suggests inhibitory effects of IL-21.
