Background: To explore the triggering mechanism of interstitial lung disease (ILD), we established the effects of immunogenic and neurogenic calcitonin gene-related peptide (CGRP) imbalance on the regulation of aquaporin 5 (AQP5) expression and the repair responses that promote the transition from alveolar epithelial cell (AEC) apoptosis to pulmonary fibrosis.

The current pandemic of COVID-19 and the identification of accessible biomarkers of disease progression is of clinical importance in the management of this novel and serious disease. This study was completed to provide information regarding 1 possible uniquely upregulated marker in this illness, eosinophil-derived neurotoxin (EDN-1). A literature search was undertaken to provide medical data regarding

Multiple myeloma (MM) remains an intractable hematological malignancy, despite recent advances in anti-MM drugs. Here, we show that role of PDZ binding kinase (PBK) in MM tumor growth. We identified that interleukin-6 (IL-6) readily increases PBK expression. Kaplan–Meier analysis showed that the MM patients with higher expression of PBK have a significant shorter survival time compared with those with

Chemotherapy resistance is one of the main reasons for tumor-related death. In particular, ovarian cancer patients often acquire drug resistance after chemotherapy. In this study, we found that the histone chaperone, nucleosome assembly protein 1-like 3 (NAP1L3), was significantly upregulated in tissues with cisplatin resistance compared with cisplatin-sensitive tissues. Patients with high NAP1L3 levels

Children with leukemia treated with methotrexate (MTX) may develop MTX-induced leukoencephalopathy, which can present as seizures or focal neurological deficits.

However, understanding of human cell-specific responses to different doses of stimuli including lipopolysaccharide (LPS) is limited. This study investigated the monocyte and classical DC (cDC)-specific, as well as the overall inflammatory response after exposure to varying doses of

Bone marrow mesenchymal stem cells (BM-MSCs) are cells with the potential to differentiate into adipocytes in oxidative stress. In this study, tert-butyl hydroperoxide is used as a stimulator that promotes reactive oxygen species in BM-MSCs. The results demonstrate that knockdown of LKB1 inhibits the transformation of BM-MSCs into adipocytes in the presence of oxidative stress. In addition, β3 adrenergic

LncRNA HOTTIP is a new lncRNA that is strictly linked to the susceptibility, growth, propagation, and prognosis of several human cancers together with colorectal cancer. lncRNA HOTTIP rs1859168 may confer colorectal cancer susceptibility through regulating its gene expression level. To elucidate its role in colorectal cancer risk, we genotyped rs1859168 A>C and measured serum HOTTIP expression level

Hepatitis C virus (HCV) causes persistent infection and invades host's innate and adaptive immune systems. During the eradication of this pathogen, the components of immune system may cause bystander damage to host, which might be even worse than the viral pathogenesis. Thus, the therapy should not only eliminate primary virus infection but also improve the inflammatory immune responses. The breakthrough

The study aimed to investigate whether recombinant human elafin can prevent hyperoxia-induced pulmonary inflammation in newborn mice, and to explore the mechanism underlying the inhibitory effects of elafin on nuclear factor-kappa B (NF-κB) signaling pathway. Neonatal C57BL/6J mice were exposed to 85% O2 for 1, 3, 7, 14, or 21 days. Then, elafin was administered daily for 20 days through intraperitoneal

Human immunodeficiency virus-tuberculosis (HIV-TB) co-infection poses a challenge to the immunologists in developing new diagnostic and therapeutic tools. Mechanisms behind the breakdown of the immune defense of the co-infected individual are poorly known. Numerous studies in HIV alone have revealed the role of PD1, TAP, and IL-10, but not in co-infection. The interaction of the 2 distinct bugs, which

Interferon-λ (IFN-λ) plays an important role in mucosal immunity, but reliable information regarding the expression of the IFN-λ receptor in individual cells is still missing. One reason for this knowledge gap is the lack of antibodies that specifically recognize the unique IFNLR1 subunit of the dimeric IFN-λ receptor complex. In this study, we investigated whether a reporter mouse carrying a bacterial

Sedentary behavior increases the risk of many chronic disorders, in addition, these chronic diseases are associated with elevated markers interleukin-6 (IL-6).

Immunohistochemistry and a DeadEnd colorimetric TUNEL

Tumor necrosis factor alpha (TNF-α) plays a paramount role in homeostasis by inducing tumor cytotoxicity and activating immune system. The signaling complexes formed by TNFR1 to activate JNK, p38, and nuclear factor-kappa B pathways and to subsequently induce apoptosis and necroptosis are well known. However, this “canonical TNF-α signaling” does not explain how ERK, AKT, and STAT3 can be activated

Bladder growth and development require continuous mechanical stimuli; however, abnormal mechanical conditions caused by partial bladder outlet obstruction (PBOO) result in detrusor smooth muscle hypertrophy and extracellular matrix accumulation. Our previous study demonstrated that PBOO induced an increase in monocyte chemotactic protein-1 (MCP-1) expression. To extensively illustrate whether and how

In this study, we investigated serum interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) after ingestion of aflatoxin B1 (AFB1) in rats. We also studied the effects of nitric oxide (NO) on the stomach after consumption of AFB1. Therefore, we hypothesized that a standard anti-inflammatory agent-melatonin (MEL), and the flavonoid-rich fractions from Chromolaena odorata (FRFC) could counteract

It is assumed that high lipid profile (HLP) causes chronic systemic inflammation, which ultimately leads to inflammatory diseases and cancers. The aim of the study was to investigate the serum concentration of proinflammatory/tumor markers of interleukin-17 (IL-17), carcinoembryonic antigen (CEA), and prostate-specific antigen (PSA) in HLP.

Prior studies have shown that HIV patients develop permanent pulmonary dysfunction following an episode of community-acquired pneumonia (CAP). However, the mechanism causing pulmonary dysfunction remains an enigma. HIV patients experience chronic inflammation. We hypothesized that CAP exacerbates inflammation in HIV patients resulting in an accelerated decline in lung function. A prospective cohort

Virus-like vesicles (VLV) are infectious, self-propagating alphavirus-vesiculovirus hybrid vaccine vectors that can be engineered to express foreign antigens to elicit a protective immune response. VLV are highly immunogenic and nonpathogenic in vivo, and we hypothesize that the unique replication and structural characteristics of VLV efficiently induce an innate antiviral response that enhances immunogenicity

Acute lung injury (ALI) is characterized by acute lung inflammation and apoptosis of alveolar epithelial cells (AECs) with a high morbidity and mortality. Procyanidin B2 (PCB2) is a naturally occurring flavonoid with anti-inflammatory activity.

Premature infants are prone to repeated lung infections after birth, which can disrupt the development of lung structure and function. However, the effects of postnatal pulmonary inflammation on lung development in newborn mice have not been reported and may play an important role in the development of bronchopulmonary dysplasia (BPD). This study aimed to establish a BPD model of postnatal pulmonary

Interferon (IFN), the first ever-described cytokine, has a potent activity against viruses. Soon since its discovery, quantification of IFN has been an important issue. Most of the traditional methods to measure IFN biological activity rely on indirect methods that quantify dyes retained by IFN-protected cells against a lytic virus, or by techniques that indirectly quantify viral replication by measuring

Hepatitis C virus (HCV) genotype 3 is very prevalent in Europe and Asia and is associated with worst outcomes than other genotypes. Genetic factors have been associated with HCV infection; however, no extensive genome-wide study has been performed among HCV genotype 3 patients. In this study, using a large cohort of 1,759 patients infected with HCV genotype 3, we explore the role of genetic variants

Since its discovery in 2013, interferon lambda 4 (IFN-λ4) has received a reputation as a paradoxical type III IFN. Difficulties in detecting IFN-λ4, especially in secreted form even led to questions about its existence. However, the genetic ability to generate IFN-λ4, determined by the presence of the rs368234815-ΔG allele, is the strongest predictor of impaired clearance of hepatitis C virus (HCV)

The retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) are a family of cytosolic pattern recognition receptors that play a critical role in binding viral RNA and triggering antiviral immune responses. The RLR LGP2 (or DHX58) is a known regulator of the RIG-I signaling pathway; however, the underlying mechanism by which LGP2 regulates RIG-I signaling is poorly understood. To better understand

The risk of hepatocellular carcinoma (HCC) is not completely eliminated in chronic hepatitis C (CHC) patients even after viral eradication. There are few studies in predicting the development of HCC using biomarker in CHC patients with sustained virologic response (SVR). We evaluated the role of the aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis-4 index (FIB-4) in predicting

Adipose tissue stores energy and is the largest endocrine organ in the body, producing several adipokines. However, among these adipokines, few play a role in the positive metabolism that promotes good health. Secreted frizzled-related protein (Sfrp)-5, an antagonist that directly binds to Wnt, has attracted interest due to its favorable effects on atherosclerotic cardiovascular disease (ASCVD). This
