Article Synopsis
  • - Atopic dermatitis (AD) involves chronic inflammation and a weakened skin barrier, worsened by factors like scratching, and this study looks into how extracellular ATP affects AD.
  • - The research found that ATP reduces filaggrin, a protein vital for skin barrier strength, and heightens inflammation by stimulating immune cell activity when released due to IL-4 and mechanical triggers.
  • - Clodronate, which inhibits ATP release, shows promise in restoring filaggrin levels and reducing inflammation in a mouse model of AD, suggesting that targeting ATP could be a new way to treat this condition.

Inflammatory stimuli cause a state of emergency myelopoiesis leading to neutrophil-like monocyte expansion. However, their function, the committed precursors, or growth factors remain elusive. In this study we find that Ym1Ly6C monocytes, an immunoregulatory entity of neutrophil-like monocytes, arise from progenitors of neutrophil 1 (proNeu1).

Homeobox A9 (HOXA9) is a transcription factor that is overexpressed in acute myeloid leukemia (AML). It is associated with the pathogenesis and progression of AML, and is a factor responsible for a poor prognosis. Therefore, the development of HOXA9-targeting molecules may contribute to not only better understanding of the mechanism of HOXA9 regulation, but also the development of therapeutic applications.

Although surgical resection is the only available treatment to achieve long-term survival in biliary tract cancer, many cases are often identified at an advanced stage at the time of diagnosis. Radiotherapy may be an alternative option to prolong survival in cases with locally advanced unresectable disease. While there are some reports of long-term survival after radiotherapy for unresectable biliary tract cancer, it is rare that clinical symptoms are exhibited by peritoneal dissemination more than 8 years after radiotherapy and that resection can be performed.
