Microglial Galectin3 enhances endothelial metabolism and promotes pathological angiogenesis via Notch inhibition by competitively binding to Jag1.

Microglia were considered as immune cells in inflammation until their angiogenic role was widely understood. Although the pro-inflammatory role of microglia in retinal angiogenesis has been explored, little is known about its role in pro-angiogenesis and the microglia-endothelia interaction. Here, we report that galectin-3 (Gal3) released by activated microglia functions as a communicator between microglia and endothelia and competitively binds to Jag1, thus inhibiting the Notch signaling pathway and enhancing endothelial angiogenic metabolism to promote angiogenesis.

Tripartite motif 16 ameliorates nonalcoholic steatohepatitis by promoting the degradation of phospho-TAK1.

Nonalcoholic steatohepatitis (NASH)-related hepatocellular carcinoma and liver disorders have become the leading causes for the need of liver transplantation in developed countries. Lipotoxicity plays a central role in NASH progression by causing endoplasmic reticulum stress and disrupting protein homeostasis. To identify key molecules that mitigate the detrimental consequences of lipotoxicity, we performed integrative multiomics analysis and identified the E3 ligase tripartite motif 16 (TRIM16) as a candidate molecule.

Translationally controlled tumor protein exerts a proinflammatory role in acute rejection after liver transplantation.

Background: Translationally controlled tumor protein (TCTP), which has been verified to have a proinflammatory activity, plays an important role in allergy. However, it remains unclear whether TCTP has an impact on the acute rejection (AR) after liver transplantation.

Methods: Three protocols were used to delineate the role of TCTP in AR after liver transplantation.

Increased Group 2 Innate Lymphoid Cells Are Correlated with Eosinophilic Granulocytes in Patients with Allergic Airway Inflammation.

The T helper 2 (Th2)-type response was considered the hypostasis of allergic airway diseases, including asthma and allergic rhinitis (AR). However, more recent studies have suggested that allergic airway inflammation also depends on innate immunity and is closely related to group 2 innate lymphoid cells (ILC2s). This study evaluated the ILC2 levels of asthma subjects, patients with asthma and AR, and healthy individuals, regarding how to investigate the relationship between clinical data and ILC2 levels.

Clinical Characteristics and Allergen Sensitization Patterns of Patients with Local Allergic Rhinitis in Southern China.

Background: Local allergic rhinitis (LAR) is characterized by the production of specific IgE (sIgE) in the nasal mucosa without evidence of systemic atopy. The characteristics of LAR in Caucasians have been well documented. LAR is understudied in China, with prevalence, patient demographics, symptomatology, and the allergen sensitization profile being poorly understood.

Suppression of the production of transforming growth factor β1, interleukin-10, and vascular endothelial growth factor in the B16F10 cells by Ganoderma lucidum polysaccharides.

Transforming growth factor β (TGF-β), interleukin-10 (IL-10), and vascular endothelial growth factor (VEGF) are three of the commonly studied cytokines playing an important role in tumor initiation and progression. Besides their promotional effects on tumor progression, the three cytokines have immunosuppressive effects that facilitate tumor initiation and progression as well. Ganoderma lucidum polysaccharides (Gl-PS) with multiple bioactivities may have the effect on B16F10 melanoma cells to induce stronger antitumor immune response that has been demonstrated.

In vivo and in vitro studies of Th17 response to specific immunotherapy in house dust mite-induced allergic rhinitis patients.

Unlabelled: T helper (Th)17 cells have been implicated in the development of allergic rhinitis (AR), but their response to specific immunotherapy (SIT) remains unclear. We investigated the impact of SIT on Th17 response and Th1/Th2 changes in AR patients. Blood samples from AR patients (n = 20) who were monosensitized to house dust mite (HDM) were collected before the initiation of SIT (SIT-untreated) and after the end of 2-year SIT (SIT-treated) treatment.

Protection against lung cancer patient plasma-induced lymphocyte suppression by Ganoderma lucidum polysaccharides.

Background/aims: This study was conducted to determine the potential of Ganoderma lucidum polysaccharides (Gl-PS) in protection against lung cancer patient plasma-induced suppression of lymphocytes. Lung cancer is a major cause of disease and loss of life in the United States and worldwide. Cancer cells release immunosuppressive mediators, such as PGE2, TGF-β, IL-10, and VEGF, to inhibit the immune response to escape from immune surveillance.

polysaccharides counteract inhibition on CD71 and FasL expression by culture supernatant of B16F10 cells upon lymphocyte activation.

Immune responses to tumor-associated antigens are often detectable in tumor-bearing hosts, but they fail to eliminate malignant cells or prevent development of metastases. Tumor cells produce factors such as interleukin-10, transforming growth factor-β1 and vascular endothelial growth factor (VEGF) that suppress the function of immune cells or induce apoptosis of immune cells. Culture supernatant of tumor cells may contain these immunosuppressive factors which suppress lymphocyte activation.

Long-term efficacy of specific immunotherapy on house dust mite-induced allergic rhinitis in China.

Objective: Although the effect of specific immunotherapy (SIT) on allergic rhinitis (AR) has been well documented in developed countries, its long-term efficacy in patients in developing countries (such as China) is poorly understood. This study investigated the long-term therapeutic and preventive effects of SIT on house dust mite (HDM)-induced AR in patients from China.

Design: Historical cohort study.

Antagonism by Ganoderma lucidum polysaccharides against the suppression by culture supernatants of B16F10 melanoma cells on macrophage.

It is well-documented that macrophages have the functions to regulate antitumor immune response. Antitumor response can be launched by a series of events, starting with inflammation mediated by monocyte/macrophages, which stimulates natural killer and dendritic cells and finally activates the cytotoxic lymphoid system. Monocytes/macrophages may be the first line of defense in tumors.

Antitumor and Immunomodulatory Effects of Polysaccharides from Broken-Spore of Ganoderma lucidum.

The antitumor and immunomodulatory activity of broken-spore of Ganodermalucidum polysaccharides (Gl-BSP) were investigated in vivo and in vitro. It was showed that Gl-BSP (50, 100, and 200 mg kg(-1)) exhibited antitumor effect against Sarcoma 180 (S180) in BALB/c mice. The Gl-BSP was not cytotoxicity in S180 cells and PG cells (human lung carcinoma cell) in vitro.

Enhanced MHC class I and costimulatory molecules on B16F10 cells by Ganoderma lucidum polysaccharides.

Purpose: It is obvious that malignant cells evade from immune system in patients with manifest malignancy. Deficient major histocompatibility complex (MHC) class I and costimulatory molecules on malignant cells partially consist of evasion strategy since antigen bond MHC and costimulatory molecules provide two signals necessary for T cell activation. Therefore, enhancement of MHC-I and costimulatory molecules may favor restraint of the evasion.
