Overactivation of inflammatory signaling in keratinocytes is critical for psoriatic skin inflammation, but its regulatory mechanisms remain incompletely understood. Here, we demonstrate that the cytokine CSBF inhibits both individual and synergistic proinflammatory signaling induced by IL-17A and TNF-α (IL-17A/TNF-α) in keratinocytes, playing a protective role in psoriatic inflammation. The expression of CSBF was increased in the skin lesions and serum of psoriatic patients, and IL-17A/TNF-α enhanced its production.

Background: Kawasaki disease (KD) is an acute pediatric vasculitis with significant implications for coronary arteries and myocardium, potentially leading to long-term myocardial fibrosis. With the advancements in speckle tracking echocardiography (STE), ultrasound parameters have been shown to be reliable in the early detection of structural and functional myocardial abnormalities, thus mitigating some limitations of cardiac magnetic resonance imaging (MRI). Despite its gold standard status for assessing myocardial fibrosis, the application of cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE) in pediatrics is restricted.

Article Synopsis
  • The choline kinase beta (CHKB) gene is vital for mitochondrial function and choline metabolism, and mutations can cause conditions like megaconial congenital muscular dystrophy (MCMD), leading to severe cardiac and neurological issues.
  • A case study involving a 13-year-old boy revealed a homozygous nonsense variant (c.598delC) in the CHKB gene, resulting in significant heart problems and neurological symptoms, while whole exome sequencing confirmed the pathogenic effect.
  • This research enhances our understanding of CHKB mutations' effects on patients and suggests that cardiac resynchronization therapy could be beneficial for those with choline metabolic disorders linked to heart complications.
