AZD 9668, a neutrophil elastase inhibitor, promotes wound healing in the irradiated skin by inhibiting NET-derived vascular dysfunction.

Despite the increasing awareness of the health risks associated with radiation exposure such as radiotherapy and accidents, effective treatments remain limited except for bone marrow damage. Radiation-induced skin damage is a critical concern as it is often accompanied by severe inflammation and delayed wound healing. Endothelial cells have emerged as a promising therapeutic target for addressing such radiation-induced damage.

Virgibacillus saliphilus sp. nov. and Virgibacillus salidurans sp. nov., isolated from kimchi.

This study aimed to provide a taxonomic description of two bacterial strains, NKC19-3T and NKC19-16T, isolated from commercially produced kimchi obtained from various regions within the Republic of Korea. Both strains were rod-shaped, gram-stain-positive, facultatively anaerobic, and displayed positive reactions for oxidase and catalase. Additionally, these bacteria were motile, halophilic (salt-tolerant), and proliferated under alkaline conditions.

A comprehensive review of synbiotics: an emerging paradigm in health promotion and disease management.

Synbiotics are complex preparations of prebiotics that can be selectively utilized by live microorganisms to improve host health. Synbiotics are divided into complementary synbiotics, which consist of probiotics and prebiotics with independent functions, and synergistic synbiotics, which consist of prebiotics that are selectively used by gut microorganisms. Complementary synbiotics used in human clinical trials include Lactobacillus spp.

Complete genome sequence of probiotic 7409N31 isolated from a healthy Hanwoo calf.

7409N31 was isolated from the feces of a healthy 11-day-old Hanwoo calf from a farm in Geochang-gun, Gyeongsangnam-do, Korea. The genome of the strain was completely sequenced using the PacBio RSII sequencing system, and it was confirmed that it was composed of one circular chromosome. The size of the entire genome was 2,198,442 bp, and it had 35.

The Radical Scavenging Activities and Anti-Wrinkle Effects of Soymilk Fractions Fermented with MK1 and Their Derived Peptides.

Soybean-derived peptides exert several beneficial effects in various experimental models. However, only a few studies have focused on the radical scavenging and anti-wrinkle effects of soymilk-derived peptides produced via different processes, such as fermentation, enzymatic treatment, and ultrafiltration. Therefore, in this study, we investigated the radical scavenging and antiwrinkle effects of soymilk fractions produced using these processes.

Monitoring mRNA Expression Patterns in Macrophages in Response to Two Different Strains of Probiotics.

As an initial study to elucidate the molecular mechanism of how probiotics modulate macrophage activity, we monitored mRNA expression patterns in peritoneal macrophages (PMs) treated with two different strains of probiotics. After treatment with either WIKIM28 or WIKIM50, total RNAs from PMs were isolated and subjected into gene chip analyses. As controls, mRNAs from vehicle (phosphate-buffered saline, PBS)-treated PMs were also subjected to gene chip analysis.

Kimchi intake alleviates obesity-induced neuroinflammation by modulating the gut-brain axis.

A high-fat diet (HFD) induces low-grade, chronic inflammation throughout the body including the hypothalamus, a key brain region involved in the control of satiety and energy expenditure in central nervous system (CNS). Kimchi is a traditional fermented Korean food, which is recognized as a healthy food. In this study, we evaluated its ability to suppress the obesity-induced inflammation in mice fed an HFD.

Phc2 controls hematopoietic stem and progenitor cell mobilization from bone marrow by repressing Vcam1 expression.

The timely mobilization of hematopoietic stem and progenitor cells (HSPCs) is essential for maintaining hematopoietic and tissue leukocyte homeostasis. Understanding how HSPCs migrate between bone marrow (BM) and peripheral tissues is of great significance in the clinical setting, where therapeutic strategies for modulating their migration capacity determine the clinical outcome. Here, we identify an epigenetic regulator, Phc2, as a critical modulator of HSPC trafficking.

Monitoring mRNA transcription of genes involved in early pregnancy from endometrium and peripheral blood mononuclear cells of pregnant pigs with different parity.

The reproductive success of mammals is largely dependent on the interaction between maternal and foetal interfaces during early pregnancy. Particularly, immune cells which reside at the maternal endometrium can modulate the conception and placental vascularization. In this study, we analysed the transcription of genes involved in early pregnancy from endometrium and peripheral blood mononuclear cells (PBMCs) of pregnant pigs with different parity.

Autophagy induced by AXL receptor tyrosine kinase alleviates acute liver injury via inhibition of NLRP3 inflammasome activation in mice.

Severe hepatic inflammation is a common cause of acute or chronic liver disease. Macrophages are one of the key mediators which regulate the progress of hepatic inflammation. Increasing evidence shows that the TAM (TYRO3, AXL and MERTK) family of RTKs (receptor tyrosine kinases), which is expressed in macrophages, alleviates inflammatory responses through a negative feedback loop.

Glabretal-type triterpenoid from the root bark of Dictamnus dasycarpus ameliorates collagen-induced arthritis by inhibiting Erk-dependent lymphocyte proliferation.

Ethnopharmacological Relevance: The root bark of Dictamnus dasycarpus Turcz. (Rutaceae) has been used as a traditional herbal medicine to treat various inflammatory diseases in East Asia. We have showed previously that a glabretal type triterpenoid (dictabretol A) from D.

Saponins from soy bean and mung bean inhibit the antigen specific activation of helper T cells by blocking cell cycle progression.

Treatment of helper T (Th) cells with saponins from soy bean and mung bean prevented their activation by inhibiting cell proliferation and cytokine secretion. However, the saponins did not affect the expression of major histocompatibility complex class II (A(b)) and co-stimulatory molecule (CD86) on professional antigen-presenting cells. Instead, the saponins directly inhibited Th cell proliferation by blocking the G(1) to S phase cell cycle transition.

Generation and evaluation of the efficacy of rhesus monkey soluble cytotoxic T lymphocyte-associated antigen-4 in the allogeneic mixed lymphocyte reaction.

Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4; CD152) is a transmembrane protein that is structurally similar to CD28. As CTLA-4 has a much higher binding affinity to B7 than CD28, several approaches using soluble CTLA-4 have been tried to down-regulate T cell activity by blocking the interaction between CD28 and B7. We constructed soluble rhesus monkey CTLA-4 immunoglobulin (CTLA-4Ig) containing a critical binding site to B7 combined with a constant Ig heavy chain region in a mammalian system.
