Aim: Treatment of inflammatory disorders relies on the intervention in immune responses thereby restoring homeostasis. IL-10 is a cytokine with therapeutic potential, but until now has not been as successful as previously anticipated. A reason for this may be that IL-10 responsiveness depends on the environment of the inflamed tissue. In this study we investigated whether GM-CSF is able to influence IL-10-mediated responses.

Methodology: Dendritic cells and macrophages were differentiated from mouse bone marrow and treated or depleted from GM-CSF prior to analyze their response to IL-10. Activity was assessed by measuring cytokine expression upon lipopolysaccharide stimulation, IL-10-induced signaling and down-stream gene expression.

Conclusion: This study describes that GM-CSF negatively regulates IL-10-mediated responses.

Background: Children diagnosed with Attention-deficit/hyperactivity disorder (ADHD) have greater difficulty in regulating their own media usage and are inclined to spend more time engaging in video games compared to neurotypical children. This study aimed to investigate the effects of ADHD severity, digital parenting awareness, and accompanying psychiatric symptoms on children's problematic media (PMU) use in children with ADHD.

Methods: The study included 95 ADHD patients aged between 6 and 11 years and 90 age-and gender-matched healthy controls.

Background: Component-resolved diagnostics are used to diagnose food allergies. Currently, reports on sensitization profiles using peach-allergen components in a multicenter setting are lacking. In this study, sensitization profiling of peach allergy was performed to evaluate the clinical utility of each component specific-immunoglobulin E antibody (sIgE ab) test.
