The immune checkpoint receptor, programmed cell death 1 (PD-1, encoded by PDCD1), mediates the immune escape of cancer, but whether PD-1 splicing isoforms contribute to this process is still unclear. Here, we identify an alternative splicing isoform of human PD-1, which carries a 28-base pairs extension retained from 5' region of intron 2 (PD-1^28), is expressed in peripheral T cells and tumor infiltrating lymphocytes. PD-1^28 expression is induced on T cells upon activation and is regulated by an RNA binding protein, TAF15.

Continuous fermentation processes increasingly emphasized cell recycling, utilization, and renewal. In this study, to improve the sustainability of the immobilized Saccharomyces cerevisiae, the cells were recovered on the surface of the glucose-responsive supports through manipulating the competitive interactions of phenylboric acid groups between glycoproteins on the cells and glucose. Through a dopamine (DA)-assisted deposition approach, 3-acrylamidophenylboronic acid (APBA) was integrated to design the saccharide-sensitive cotton fibers (APBA@PDA-CF).

Article Synopsis
  • Microvascular hyperpermeability, which is a key characteristic of inflammation, can have harmful effects if it lasts too long, leading to the proposal of targeted therapies to manage its duration.
  • The study tested how inflammatory signals like platelet-activating factor (PAF) and vascular endothelial growth factor (VEGF) cause hyperpermeability and whether activating the cAMP-dependent pathway through Epac1 could help reverse this process.
  • Results showed that stimulation of Epac1 effectively reduced hyperpermeability in both mouse tissues and human cells, with the mechanism involving the translocation of eNOS and a delayed increase in cAMP levels linked to nitric oxide production.

Article Synopsis
  • Vascular calcification (VC) is linked to aging and is worsened by a lack of Klotho, a protein that can be restored to alleviate VC symptoms.
  • Research shows that low Klotho levels correlate with increased aortic calcification, and Klotho-deficient mice experience VC that improves with Klotho protein supplementation.
  • Increased autophagy is observed in Klotho-deficient mice, protecting them from VC, and Klotho aids in reducing calcification by enhancing autophagy in both these mice and vascular smooth muscle cells.

Graphene-based materials are widely used in the field of immobilized enzymes due to their easily tunable interfacial properties. We designed amphiphilic nanobiological interfaces between graphene oxide (GO) and lipase TL () with tunable reduction degrees through molecular dynamics simulations and a facile chemical modulation, thus revealing the optimal interface for the interfacial activation of lipase TL and addressing the weakness of lipase TL, which exhibits weak catalytic activity due to an inconspicuous active site lid. It was demonstrated that the reduced graphene oxide (rGO) after 4 h of ascorbic acid reduction could boost the relative enzyme activity of lipase TL to reach 208%, which was 48% higher than the pristine GO and 120% higher than the rGO after 48 h of reduction.

  • The intestinal microenvironment consists of gut microbiota that plays a significant role in human health and is linked to various diseases, including pancreatic cancer (PC), which has a low 5-year survival rate.
  • PC is difficult to diagnose early, often leading patients to miss out on potentially life-saving surgery; its causes are not fully understood but can be influenced by factors like diet, lifestyle, and existing health conditions.
  • Research indicates that the gut microbiota's imbalance and certain metabolic processes are closely associated with PC development and prognosis, making it crucial to explore these correlations for better diagnosis and treatment strategies.

Introduction: Pulmonary artery pressure (PAP) is increased and right ventricular (RV) function is well preserved in healthy subjects upon exposure to high altitude (HA). An increase in PAP may trigger notching of the right ventricular outflow tract Doppler flow velocity envelope (RVOT notch), which is associated with impaired RV function in patients with pulmonary hypertension. However, whether HA exposure can induce RVOT notch formation and the subsequent impact on cardiac function in healthy subjects remains unclear.
