Phospholipase D2 downregulates interleukin-1β secretion from tumor-associated macrophages to suppress bladder cancer progression.

The tumor microenvironment (TME) modulates therapeutic response and prognosis in patients with bladder cancer (BC). The roles of two phospholipase D (PLD) isoforms, PLD1 and PLD2 (hydrolysis of phosphatidylcholine to phosphatidic acid), in cancer cells have been well-studied in numerous cancer types, but their roles in the TME remain unclear. We used a mouse BC Pld2-KO carcinogenesis model and global transcriptomic analysis to reveal that PLD2 was significantly involved in BC progression through immunosuppressive pathways in the TME.

Aggregation-induced circularly polarized phosphorescence of Pt(II) complexes with an axially chiral BINOL ligand.

A pair of chiral Pt(II) complexes coordinated by simple BINOL and bipyridine ligands displaying aggregation-induced phosphorescence and circularly polarized luminescence were characterized by X-ray crystallography and absorption and emission spectroscopies. The emission of the powder sample was reddish whereas the thin film dispersed in PMMA ( = 1 wt%) exhibited a white emission.

Safety and efficacy of DTaP-IPV vaccine use in healthcare workers for prevention of pertussis.

Pertussis can be fatal for infants. The best way to prevent infant pertussis is to promote adult immunization. However, Tdap has not been licensed in Japan, so we investigated the effect and safety of the DTaP-IPV vaccine instead.

Flow cytometric method for enumeration and classification of reactive immature granulocyte populations.

We developed a flow cytometric method for the enumeration and classification of nonmalignant immature granulocytes (IG). In this study, IG are defined as most immature (IG stage 1: promyelocytes and myelocytes) and as more mature (IG stage 2: metamyelocytes). Blood specimens from 46 patients with documented infectious or inflammatory disease and known presence of IG (by routine manual microscopy) were analyzed.
