An endoplasmic reticulum and lipid droplets dual-localized strategy to develop small molecular photosensitizers that induce ferroptosis during photodynamic therapy.

Organelle-localized photosensitizers have been well-developed to enhance the photodynamic therapy (PDT) efficacy through triggering given cell death. The endoplasmic reticulum (ER) and lipid droplets (LDs) are two key organelles mutually regulating ferroptosis. Thus, in this study, small molecular photosensitizer CAR PSs were developed through fragment integration strategy and the heavy-atom modification.

Hyper-Interferon Sensitive Influenza Induces Adaptive Immune Responses and Overcomes Resistance to Anti-PD-1 in Murine Non-Small Cell Lung Cancer.

Despite recent advances in immunotherapy with immune checkpoint inhibitors, many patients with non-small cell lung cancer (NSCLC) fail to respond or develop resistance after an initial response. In situ vaccination (ISV) with engineered viruses has emerged as a promising antigen-agnostic strategy that can both condition the tumor microenvironment and augment antitumor T-cell responses to overcome immune resistance. We engineered a live attenuated viral vaccine, hyper-IFN-sensitive (HIS) virus, by conducting a genome-wide functional screening and introducing eight IFN-sensitive mutations in the influenza genome to enhance host IFN response.

Design and synthesis of 7-membered lactam fused hydroxypyridinones as potent metal binding pharmacophores (MBPs) for inhibiting influenza virus PA endonuclease.

Since influenza virus RNA polymerase subunit PA is a dinuclear Mn dependent endonuclease, metal-binding pharmacophores (MBPs) with Mn coordination has been elucidated as a promising strategy to develop PA inhibitors for influenza treatment. However, few attentions have been paid to the relationship between the optimal arrangement of the donor atoms in MBPs and anti-influenza A virus (IAV) efficacy. Given that, the privileged hydroxypyridinones fusing a seven-membered lactam ring with diverse side chains, chiral centers or cyclic systems were designed and synthesized.

Exogenous extracellular polymeric substances as protective agents for the preservation of anammox granules.

The preservation of anammox granules is of great significance for the rapid start-up of the anammox process and improvement of performance stability. Therefore, it is necessary to explore an economical and stable preservation strategy. Exogenous extracellular polymeric substances (EPS) were used as protective agents for the preservation of anammox granules in this study.

Olmesartan inhibits the expression of monocyte chemoattractant protein-1 and tumor necrosis factor-alpha and improves vascular remodeling after vascular injury in mouse.

Objective: To investigate the neointima formation and the expression of monocyte chemoattractant protein-1 (MCP-1) and tumor necrosis factor-alpha (TNF-alpha) in cuff-induced vascular injury in mouse model, and to examine the effect of angiotensin II type 1 receptor (AT1) blocker, olmesartan, on MCP-1 and TNF-alpha expression and consequently vascular remodeling.

Methods: Vascular injury was induced by polyethylene cuff-placement around the mouse femoral artery. Some mice were treated with AT1 receptor blocker, olmesartan, at the dose of 3 mg.
