Estrogen-related genes for thyroid cancer prognosis, immune infiltration, staging, and drug sensitivity.

Background: Thyroid cancer (THCA) has become increasingly common in recent decades, and women are three to four times more likely to develop it than men. Evidence shows that estrogen has a significant impact on THCA proliferation and growth. Nevertheless, the effects of estrogen-related genes (ERGs) on THCA stages, immunological infiltration, and treatment susceptibility have not been well explored.

Protein spectrum changes in exosomes after therapeutic plasma exchange in patients with neuromyelitis optica.

Introduction: Neuromyelitis optica (NMO) is an autoimmune disease with a high rate of blindness and positive for the detection of aquaporin-4 antibody (AQP4) in most patients. NMO acute attacks are managed by high-doses of intravenous methylprednisolone followed by oral taper, and if symptoms fail to resolve, therapeutic plasma exchange (TPE) is added. TPE can remove pathological antibodies and inflammatory factors leading to clinical improvement.

Expression of Dual-Specificity Phosphatase 2 (DUSP2) in Patients with Serous Ovarian Carcinoma and in SKOV3 and OVCAR3 Cells In Vitro.

BACKGROUND Ovarian cancer commonly presents at a late stage and is associated with poor prognosis. The most common histological subtype is serous ovarian carcinoma. Dual-specificity phosphatase 2 (DUSP2) is a protein phosphatase and substrate for mitogen-activated protein kinases (MAPKs) with increased expression levels in malignancy.

Induction of Pluripotent Stem Cell-Derived Cardiomyocyte Toxicity by Supernatant of Long Term-Stored Red Blood Cells in Vitro.

Background/aims: Preserved red blood cells (RBCs) in vitro undergo a series of morphological, functional and metabolic changes during storage. RBC metabolites accumulate over time during storage, the toxicity of the supernatants of RBCs (SSRBCs) on tissue cells is largely unknown. Here, we aimed to study cardiomyocyte toxicity by supernatant of long term-stored RBCs in vitro and to discover elements involved in the mechanism.

Respiratory syncytial virus protects against the subsequent development of ovalbumin-induced allergic responses by inhibiting Th2-type γδ T cells.

Respiratory syncytial virus (RSV) infection has been hypothesized to be a risk factor for the development of allergy and asthma, but epidemiologic studies in humans still remain inconclusive. The association between RSV infection and allergic diseases may be dependent on an atopic background and previous history of RSV infection. It has been reported that RSV infection before sensitization to an allergen decreased the production of Th2-like cytokines in the lung and the levels of allergen-specific Th2-type antibodies in the serum.

A prophylactic effect of an oligodeoxynucleotide containing a cytidine-guanosine motif against Japanese cedar pollen-induced T-helper type 2 allergic response.

Background: Over 10% of entire population in Japan suffer from allergic diseases induced by Japanese cedar pollen (JCP) every spring. In terms of preventive medicine, it has become a matter of urgency to establish successful prophylactic and therapeutic strategies for controlling the disorders. The effect of an oligodeoxynucleotide containing a cytidine-guanosine motif (CpG ODN) on the regulation of immune responses induced by JCP was investigated in this study.

Anti-HLA class I antibody binding to airway epithelial cells induces production of fibrogenic growth factors and apoptotic cell death: a possible mechanism for bronchiolitis obliterans syndrome.

Development of anti-HLA class I antibodies is associated with bronchiolitis obliterans syndrome (BOS) after lung transplantation.

Thus, this study was designed to determine whether anti-HLA class I antibodies can activate AECs to produce growth factors and to undergo apoptosis.

Glucan stimulates human dermal fibroblast collagen biosynthesis through a nuclear factor-1 dependent mechanism.

Glucan, an immunomodulator, has been reported to increase collagen deposition and tensile strength in experimental models of wound repair. Previous data suggest that glucan modulates wound healing via an indirect mechanism in which macrophages are stimulated to release growth factors and cytokines. However, recent data have shown the presence of glucan receptors on normal human dermal fibroblasts, suggesting that glucans may be able to directly stimulate fibroblast collagen biosynthesis.
