kn-abstract=Activated factor X (FXa) induces inflammatory response and cell proliferation in various cell types via activation of proteinase-activated receptor-1 (PAR1) and/or PAR2. We thus aimed to investigate the impact of FXa on the development of pulmonary arterial hypertension (PAH) and the mechanisms involved. The effects of edoxaban, a selective FXa inhibitor, on hemodynamic, right ventricular (RV) hypertrophy, and vascular remodeling were evaluated in a monocrotaline (MCT)-exposed pulmonary hypertension (PH) rat model. At 21 days after a single subcutaneous injection of MCT of 60 mg/kg, right ventricular systolic pressure (RVSP) and total pulmonary vascular resistance index (TPRI) were elevated concomitant with the increased plasma FXa and lung interleukin-6 (IL-6) mRNA. Daily administration of edoxaban (10 mg/kg/day, by gavage) starting from the day of MCT injection for 21 days ameliorated RVSP, TPRI, RV hypertrophy, pulmonary vascular remodeling, and macrophage accumulation. Edoxaban reduced nuclear factor-kappa B (NF-ƒÈB) activity and IL-6 mRNA level in the lungs of MCT-exposed rats. mRNA levels of FXa, PAR1, and PAR2 in cultured pulmonary arterial smooth muscle cells (PASMCs) isolated from patients with PAH were higher than those seen in normal PASMCs. FXa stimulation increased cell proliferation and mRNA level of IL-6 in normal PASMCs, both of which were blunted by edoxaban and PAR1 antagonist. Moreover, FXa stimulation activated extracellularly regulated kinases 1/2 in a PAR1-dependent manner. Inhibition of FXa ameliorates NF-ƒÈB-IL-6-mediated perivascular inflammation, pulmonary vascular remodeling, and the development of PH in MCT-exposed rats, suggesting that FXa may be a potential target for the treatment of PAH.
NEW & NOTEWORTHY This study demonstrated that chronic treatment with activated factor X (FXa) inhibitor ameliorated NF-ƒÈB-IL-6-mediated perivascular inflammation in a rat model with pulmonary arterial hypertension, which is associated with elevated FXa activity. FXa may act on pulmonary arterial smooth muscle cells, inducing cell proliferation and inflammatory response via upregulated PAR1, thereby contributing to pulmonary vascular remodeling. Understanding the patient-specific pathophysiology is a prerequisite for applying FXa-targeted therapy to the treatment of pulmonary arterial hypertension.

kn-title=Preventive effects of vasohibin-2-targeting peptide vaccine for diabetic nephropathy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Diabetic nephropathy remains the leading cause of end-stage kidney disease in many countries, and additional therapeutic targets are needed to prevent its development and progression. Some angiogenic factors are involved in the pathogenesis of diabetic nephropathy. Vasohibin-2 (VASH2) is a novel proangiogenic factor, and our previous study showed that glomerular damage is inhibited in diabetic Vash2 homozygous knockout mice. Therefore, we established a VASH2-targeting peptide vaccine as a tool for anti-VASH2 therapy in diabetic nephropathy. In this study, the preventive effects of the VASH2-targeting peptide vaccine against glomerular injury were examined in a streptozotocin (STZ)-induced diabetic mouse model. The mice were subcutaneously injected with the vaccine at two doses 2 wk apart and then intraperitoneally injected with 50 mg/kg STZ for 5 consecutive days. Glomerular injury was evaluated 20 wk after the first vaccination. Treatment with the VASH2-targeting peptide vaccine successfully induced circulating anti-VASH2 antibody without inflammation in major organs. Although the vaccination did not affect blood glucose levels, it significantly prevented hyperglycemia-induced increases in urinary albumin excretion and glomerular volume. The vaccination did not affect increased VASH2 expression but significantly inhibited renal angiopoietin-2 (Angpt2) expression in the diabetic mice. Furthermore, it significantly prevented glomerular macrophage infiltration. The preventive effects of vaccination on glomerular injury were also confirmed in db/db mice. Taken together, the results of this study suggest that the VASH2-targeting peptide vaccine may prevent diabetic glomerular injury in mice by inhibiting Angpt2-mediated microinflammation.

kn-title=Tactile angle discriminability improvement: contributions of working memory training and continuous attended sensory input
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Perceptual learning is commonly assumed to enhance perception through continuous attended sensory input. However, learning is generalizable to performance in untrained stimuli and tasks. Although previous studies have observed a possible generalization effect across tasks as a result of working memory (WM) training, comparisons of the contributions of WM training and continuous attended sensory input to perceptual learning generalization are still rare. Therefore, we compared which factors contributed most to perceptual generalization and investigated which skills acquired during WM training led to tactile generalization across tasks. Here, a Braille-like dot pattern matching n-back WM task was used as the WM training task, with four workload levels (0, 1, 2, and 3-back levels). A tactile angle discrimination (TAD) task was used as a pre- and posttest to assess improvements in tactile perception. Between tests, four subject groups were randomly assigned to four different workload n-back tasks to consecutively complete three sessions of training. The results showed that tactile n-back WM training could enhance TAD performance, with the 3-back training group having the highest TAD threshold improvement rate. Furthermore, the rate of WM capacity improvement on the 3-back level across training sessions was correlated with the rate of TAD threshold improvement. These findings suggest that continuous attended sensory input and enhanced WM capacity can lead to improvements in TAD ability, and that greater improvements in WM capacity can predict greater improvements in TAD performance.
NEW & NOTEWORTHY Perceptual learning is not always specific to the trained task and stimuli. We demonstrate that both continuous attended sensory input and improved WM capacity can be used to enhance tactile angle discrimination (TAD) ability. Moreover, WM capacity improvement is important in generalizing the training effect to the TAD ability. These findings contribute to understanding the mechanism of perceptual learning generalization across tasks.

kn-title=Tactile angle discriminability improvement: roles of training time intervals and different types of training tasks
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Perceptual learning, which is not limited to sensory modalities such as vision and touch, emerges within a training session and between training sessions and is accompanied by the remodeling of neural connections in the cortex. However, limited knowledge exists regarding perceptual learning between training sessions. Although tactile studies have paid attention to between-session learning effects, there have been few studies asking fundamental questions regarding whether the time interval between training sessions affects tactile perceptual learning and generalization across tactile tasks. We investigated the effects of different training time intervals on the consecutive performance of a tactile angle discrimination (AD) task and a tactile orientation discrimination (OD) task training on tactile angle discriminability. The results indicated that in the short-interval training group, AD task performance significantly improved in the early stage of learning and nearly plateaued in the later stage, whereas in the long-interval training group, significant improvement was delayed and then also nearly plateaued in the later stage; additionally, improved OD task performance resulted in improved AD task performance. These findings suggest that training time interval affects the early stage of learning but not the later stage and that generalization occurs between different types of tactile tasks.
