• PTGER4–HDAC Signaling in Rectal Epithelium

  2026-08-31

  Anbazhagan et al. identify a signaling route in which mesenchymal stromal cell-derived PGE2 activates PTGER4 in rectal epithelial organoids, alters class IIa HDAC phosphorylation, and increases SPINK4 mRNA. The work connects stromal–epithelial communication with an epigenetic regulatory mechanism relevant to mucosal repair and inflammatory bowel disease research.

• H5N1 mRNA Vaccine Protects Lactating Dairy Cows

  2026-08-30

  A hemagglutinin-encoding mRNA–lipid nanoparticle vaccine protected lactating dairy cows against a high-dose H5N1 challenge and maintained meaningful protection into a late follow-up period.
