Transcriptomic landscapes of STING-mediated DNA-sensing reveal cellular response heterogeneity.

Transfection of plasmid DNA (pDNA) encoding target genes is a routine tool in gene function studies and therapeutic applications. However, nucleic acid-sensing-mediated innate immune responses influence multiple intracellular signaling pathways. The stimulator of interferon genes (STING) is a crucial adapter protein for DNA sensors in mammalian cells.

B7H6 is the predominant activating ligand driving natural killer cell-mediated killing in patients with liquid tumours: evidence from clinical, in silico, in vitro, and in vivo studies.

Background: Natural killer (NK) cells are a subset of innate lymphoid cells that are inherently capable of recognizing and killing infected or tumour cells. This has positioned NK cells as a promising live drug for tumour immunotherapy, but limited success suggests incomplete knowledge of their killing mechanism. NK cell-mediated killing involves a complex decision-making process based on integrating activating and inhibitory signals from various ligand-receptor repertoires.

Understanding nucleic acid sensing and its therapeutic applications.

Nucleic acid sensing is involved in viral infections, immune response-related diseases, and therapeutics. Based on the composition of nucleic acids, nucleic acid sensors are defined as DNA or RNA sensors. Pathogen-associated nucleic acids are recognized by membrane-bound and intracellular receptors, known as pattern recognition receptors (PRRs), which induce innate immune-mediated antiviral responses.

The infusion of ex vivo, interleukin-15 and -21-activated donor NK cells after haploidentical HCT in high-risk AML and MDS patients-a randomized trial.

Clinical effect of donor-derived natural killer cell infusion (DNKI) after HLA-haploidentical hematopoietic cell transplantation (HCT) was evaluated in high-risk myeloid malignancy in phase 2, randomized trial. Seventy-six evaluable patients (aged 21-70 years) were randomized to receive DNKI (N = 40) or not (N = 36) after haploidentical HCT. For the HCT conditioning, busulfan, fludarabine, and anti-thymocyte globulin were administered.

The antiaging effects of a product containing collagen and ascorbic acid: In vitro, ex vivo, and pre-post intervention clinical trial.

Various substances, including collagen (Naticol®) and ascorbic acid, that inhibit and prevent skin aging have been studied. Collagen prevents skin aging, has anti-inflammatory effects, and assists in normal wound healing. Ascorbic acid is a representative antioxidant that plays a role in collagen synthesis.

Stepwise transmigration of T- and B cells through a perivascular channel in high endothelial venules.

High endothelial venules (HEVs) effectively recruit circulating lymphocytes from the blood to lymph nodes. HEVs have endothelial cells (ECs) and perivascular sheaths consisting of fibroblastic reticular cells (FRCs). Yet, post-luminal lymphocyte migration steps are not well elucidated.

Transforming Growth Factor β Inhibits MUC5AC Expression by Smad3/HDAC2 Complex Formation and NF-κB Deacetylation at K310 in NCI-H292 Cells.

Airway mucus secretion is an essential innate immune response for host protection. However, overproduction and hypersecretion of mucus, mainly composed of the gel- forming MUC5AC protein, are significant risk factors for patients with asthma and chronic obstructive pulmonary disease (COPD). The transforming growth factor β (TGFβ) signaling pathway negatively regulates MUC5AC expression; however, the underlying molecular mechanism is not fully understood.

A three-dimensional hyaluronic acid-based niche enhances the therapeutic efficacy of human natural killer cell-based cancer immunotherapy.

Adoptive transfer of natural killer (NK) cells is becoming one of the most important parts of cancer immunotherapy. However, recent accomplishments have focused on the improvement of the targeting effects based on the engineering of chimeric antigen receptors (CARs) on cell surfaces. Despite the large quantity of therapeutic cells required for clinical applications, the technology for ex vivo expansion is not well developed.

Macrophage migration inhibitory factor interacts with thioredoxin-interacting protein and induces NF-κB activity.

The nuclear factor kappa B (NF-κB) pathway is pivotal in controlling survival and apoptosis of cancer cells. Macrophage migration inhibitory factor (MIF), a cytokine that regulates the immune response and tumorigenesis under inflammatory conditions, is upregulated in various tumors. However, the intracellular functions of MIF are unclear.

Effects of amoxicillin/clavulanic acid on the pharmacokinetics of valproic acid.

Valproic acid (VPA) is mainly metabolized via glucuronide, which is hydrolyzed by β-glucuronidase and undergoes enterohepatic circulation. Amoxicillin/clavulanic acid (AMC) administration leads to decreased levels of β-glucuronidase-producing bacteria, suggesting that these antibiotics could interrupt enterohepatic circulation and thereby alter the pharmacokinetics of VPA. This study aimed to evaluate the effects of AMC on the pharmacokinetics of VPA.

Bioequivalence evaluation of two amlodipine salts, besylate and orotate, each in a fixed-dose combination with olmesartan in healthy subjects.

A fixed-dose combination of amlodipine and olmesartan is used to treat high blood pressure in patients whose hypertension is not sufficiently controlled with either drug alone. The objective of this study was to evaluate the bioequivalence of two fixed-dose combinations, ie, amlodipine orotate/olmesartan medoxomil 10/40 mg and amlodipine besylate/olmesartan medoxomil 10/40 mg, in healthy subjects. A randomized, open-label, single-dose, two-sequence, two-period, crossover study was conducted in 30 healthy adult volunteers.

A pharmacokinetic and pharmacodynamic drug interaction between rosuvastatin and valsartan in healthy subjects.

The Atopic Dermatitis Antecubital Severity score: validity, reliability, and sensitivity to change in patients with atopic dermatitis.

Background: The Atopic Dermatitis Antecubital Severity (ADAS) score is a new objective scale for the assessment of the severity of atopic dermatitis (AD). It is calculated by multiplying the intensity of inflammatory signs by the size of an antecubital eczema lesion.

Aim: To test the validity, reliability, and sensitivity to changes of the ADAS score compared with those of the Eczema Area and Severity Index (EASI) score.

Protective effects of skin permeable epidermal and fibroblast growth factor against ultraviolet-induced skin damage and human skin wrinkles.

Background: Epidermal and fibroblast growth factor (EGF and FGF1) proteins play an important role in the regeneration and proliferation of skin cells. EGF and FGF1 have considerable potential as possible therapeutic or cosmetic agents for the treatment of skin damage including wrinkles.

Objectives: Using protein transduction domains (PTD), we investigated whether PTD-EGF and FGF1 transduced into skin cells and tissue.

HSV-1 ICP27 suppresses NF-kappaB activity by stabilizing IkappaBalpha.

Nuclear factor kappaB (NF-kappaB) is associated with the transcriptional activation of genes encoding chemokines, adhesion molecules, cytokines, and anti-apoptotic proteins, which are key components in immune responses and viral infection. Many viruses modulate NF-kappaB through numerous viral gene products to allow productive infections and immune escape. Here we report that herpes simplex virus-1 infected cell protein 27 (HSV-1 ICP27), an immediate early protein of HSV-1, represses NF-kappaB activity through binding to inhibitor of kappaB (IkappaBalpha), blocking phosphorylation and ubiquitination of IkappaBalpha, and stabilizing IkappaBalpha.
