Why Is IFN-λ Less Inflammatory? One IRF Decides.

Type I and type III interferons (IFNs) activate similar antiviral transcriptional programs, but the type I IFN response is more inflammatory. In this issue of Immunity, Forero et al. find that selective induction of the transcription factor IRF1 promotes proinflammatory chemokine expression downstream of type I IFN signaling.


Shared and Distinct Functions of Type I and Type III Interferons.

Type I interferons (IFNs) (IFN-α, IFN-β) and type III IFNs (IFN-λ) share many properties, including induction by viral infection, activation of shared signaling pathways, and transcriptional programs. However, recent discoveries have revealed context-specific functional differences. Here, we provide a comprehensive review of type I and type III IFN activities, highlighting shared and distinct features from molecular mechanisms through physiological responses. Beyond discussing canonical antiviral functio...

The role of type I interferons in CD4 T cell differentiation.

Type I interferons (IFNs) released upon viral infections play different and opposing roles in disease outcome. This pleiotropic effect is mainly influenced by the cellular sources, timing and target cells for these molecules. The effect of type I IFN signaling on the activation and differentiation of antiviral CD4 T cells remains ill defined, with studies reporting either a beneficial or a detrimental role, depending on the context of infection. This review will highlight several recent studies that have in...


Maternal high-fructose intake increases circulating corticosterone levels via decreased adrenal corticosterone clearance in adult offspring.

Global fructose consumption is on the rise; however, maternal high-fructose intake may have adverse effects on offspring. We previously demonstrated that excessive fructose intake by rat dams altered steroidogenic gene transcription in the hippocampus of offspring. Herein, we examined how maternal high-fructose intake influences the regulation of adrenal glucocorticoid levels in offspring. Rat dams received 20% fructose solution during gestation and lactation. After weaning, the offspring were provided norm...

Digesta passage in nondomestic ruminants: Separation mechanisms in 'moose-type' and 'cattle-type' species, and seemingly atypical browsers.

Ruminants have been classified as having a 'moose-type' or 'cattle-type' digestive physiology. 'Cattle-type' ruminants have a clear difference in the mean retention time (MRT) of fluid vs. small particles in the reticulorumen (RR), with a high 'selectivity factor' (SF = MRT/ MRT, >1.80), and are typically grazers and intermediate feeders. 'Moose-type' ruminants have lower SF (

Circulating Serum Myonectin Levels in Obesity and Type 2 Diabetes Mellitus.

Myonectin is one of the myokines and has gained interest as a potential new strategy to combat obesity and its associated disorders, such as type 2 diabetes mellitus (T2DM).The objective of this study was to investigate circulating serum myonectin levels in nondiabetes and T2DM and elucidate possible relationships between serum myonectin levels and metabolic parameters in patients with T2DM.

Circulating metabolites in progression to islet autoimmunity and type 1 diabetes.

Metabolic dysregulation may precede the onset of type 1 diabetes. However, these metabolic disturbances and their specific role in disease initiation remain poorly understood. In this study, we examined whether children who progress to type 1 diabetes have a circulatory polar metabolite profile distinct from that of children who later progress to islet autoimmunity but not type 1 diabetes and a matched control group.

Methods for type I interferon detection and their relevance for clinical utility and improved understanding of rheumatic diseases.

Type I interferons (IFN) are a class of inducible and protective cytokines best known for immune defence against viruses and intracellular bacteria. Inappropriate stimulation or defective negative regulation of type I IFN expression however can lead to persistent type I IFN activity with detrimental effects. This is particularly relevant for a class of monogenic autoinflammatory diseases ("type I interferonopathies"), along with many other complex rheumatic diseases such as systemic lupus erythematosus (SLE...

Type-Specific Crosstalk Modulates Interferon Signaling in Intestinal Epithelial Cells.

Intestinal epithelial cells (IECs) are the primary target of enteric viruses. Their infection by viruses leads to the upregulation of both type I and type III interferons (IFNs). These IFNs then act in an autocrine and paracrine manner to protect IECs from viral propagation. To date, whether both IFNs use similar signaling pathways and whether these 2 cytokines can act synergistically to protect against viral infection remain unclear. Using human IECs depleted of either the type I or type III IFN receptor, ...

Type I interferon signature in Sjögren's syndrome: pathophysiological and clinical implications.

Type I interferons (IFN) have long been recognised as mediators of innate immune defense mechanisms against viral threats. Robust evidence over the last 15 years revealed their significant role in the pathogenesis of systemic autoimmune diseases, including systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS). Despite the progress, methods of detection, initial triggers, biological functions and clinical associations in the setting of autoimmunity remain to be fully clarified. As therapeutic optio...

Circulating antibodies against M-type phospholipase A2 receptor and thrombospondin type-1 domain-containing 7A in Chinese patients with membranous nephropathy.

M-type phospholipase A2 receptor (PLA2R) and thrombospondin type-1 domain-containing 7A (THSD7A) have recently been identified as target antigens for patients with idiopathic membranous nephropathy (IMN). The prevalence of PLA2R and THSD7A in the serum of MN patients deserves further investigation.

Cytomorphologic comparison of type 1 and type 2 papillary renal cell carcinoma: A retrospective analysis of 28 cases.

Papillary renal cell carcinoma (pRCC) is classified as type 1 or type 2 on the basis of histomorphologic features. Type 1 pRCC typically carries a better prognosis, and renal cell carcinoma is often diagnosed by fine-needle aspiration (FNA). Thus, this study was designed to characterize cytomorphologic features present in FNA cases that could be used to discriminate between type 1 and type 2 pRCC.

High risk endometrial cancer: clues towards a revision of the therapeutic paradigm.

Endometrial cancer (EC) is a major cause of mortality worldwide with nearly 200 000 cases diagnosed annually. The recent ESMO-ESGO-ESTRO guidelines include a new classification defining a heterogeneous high-risk group of recurrence (HR) comprising: (i) endometrioid (type 1) FIGO stage IB grade 3 tumors (type 1/G3ECs), (ii) non-endometrioid tumors (type 2) and (iii) advanced stages whatever the histological type (Colombo et al., 2016).

Systematic Review and Meta-Analysis of Randomized Controlled Trials on the Effect of SGLT2 Inhibitor on Blood Leptin and Adiponectin Level in Patients with Type 2 Diabetes.

Sodium glucose cotransporter 2 (SGLT2) inhibitors are a new kind of hypoglycemic drugs that improve glucose homeostasis by inhibiting renal glucose reabsorption. Recent studies have shown that SGLT2 inhibitors can also mediate body metabolism through regulation of adipokines level, but the effects of SGLT2 inhibitors on the concentration of adipokines (leptin and adiponectin) remains controversial. This meta-analysis was set out to evaluate the changes in circulating leptin and adiponectin levels in patient...

Topical Applications of an Emollient Reduce Circulating Pro-Inflammatory Cytokine Levels in Chronically Aged Humans: A Pilot Clinical Study.

While increased levels of circulating inflammatory cytokines in chronologically aged humans have been linked to the development of aging-associated chronic disorders (e.g., cardiovascular disease, type II diabetes, osteoporosis and Alzheimer's disease), approaches that reduce circulating cytokines are not yet available. In chronologically aged mice, we recently demonstrated that epidermal dysfunction largely accounts for age-associated elevations in circulating cytokine levels, and that improving epidermal ...

Enhanced T-cell maturation and monocyte aggregation are features of cellular inflammation in human T-lymphotropic virus type-1-associated myelopathy.

Human T-lymphotropic virus type-1 (HTLV-1) associated myelopathy (HAM), is an inflammatory condition characterised by severe disability and high levels of infected white blood cells. The circulating cellular inflammatory changes that distinguish this condition from asymptomatic infection are not well understood.

Type 1 diabetes defined by severe insulin deficiency occurs after 30 years of age and is commonly treated as type 2 diabetes.

Late-onset type 1 diabetes can be difficult to identify. Measurement of endogenous insulin secretion using C-peptide provides a gold standard classification of diabetes type in longstanding diabetes that closely relates to treatment requirements. We aimed to determine the prevalence and characteristics of type 1 diabetes defined by severe endogenous insulin deficiency after age 30 and assess whether these individuals are identified and managed as having type 1 diabetes in clinical practice.

N-terminal pro-B-type natriuretic peptide and outcomes in type B aortic dissection in China: a retrospective multicentre study.

N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) is an unfavourable factor responsible for poor outcomes in the cardiovascular diseases. Nevertheless, the prognostic role of NT-pro-BNP in type B aortic dissection (TBAD) remains unclear. The aim of the current study was to investigate the relationship between NT-pro-BNP levels and in-hospital and long-term adverse prognosis in patients with TBAD.

Hippocampal Gene Expression is Increased in Late-Stage Alzheimer's Disease.

Lamins are fibrillary proteins that are crucial in maintaining nuclear shape and function. Recently, B-type lamin dysfunction has been linked to tauopathies. However, the role of A-type lamin in neurodegeneration is still obscure. Here, we examined A-type and B-type lamin expression levels by RT-qPCR in Alzheimer's disease (AD) patients and controls in the hippocampus, the core of tau pathology in the brain. , and genes showed moderate mRNA levels in the human hippocampus with highest expression for the ...

Alterations in the metabolism of phospholipids, bile acids and branched-chain amino acids predicts development of type 2 diabetes in black south African women: a prospective cohort study.

South Africa (SA) has the highest global projected increase in diabetes risk. Factors typically associated with insulin resistance and type 2 diabetes risk in Caucasians are not significant correlates in black African populations. Therefore, we aimed to identify circulating metabolite patterns that predict type 2 diabetes development in this high-risk, yet understudied SA population.

Investigation of the relationship between IL-6 and type 2 biomarkers in severe asthma.

Combination of IL-6 (non-Type 2 asthma) and FeNO or blood eosinophil count (Type 2 asthma) identified asthma endotypes related to asthma severity, exacerbations, and responsiveness to corticosteroids and potential for response to anti-Type 2 and anti-IL-6 treatment.

An anatomical study on lumbar arteries related to the extrapedicular approach applied during lumbar PVP (PKP).

To observe the regional anatomy of the lumbar artery (LA) associated with the extrapedicular approach applied during percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP), we collected 78 samples of abdominal computed tomography angiography imaging data. We measured the nearest distance from the center of the vertebral body puncture point to the LA (distance VBPP-LA, DVBPP-LA). According to the DVBPP-LA, four zones, Zone I, Zone II, Zone III and Zone IV, were identified. LAs that passed throu...

Toward a better understanding of type I interferonopathies: a brief summary, update and beyond.

This review briefly summarized the recent progresses of type I interferonopathy focusing on the clinical and molecular features, pathogeneses, diagnoses and potential therapies.

IFN-λ3 as a host immune response in acute hepatitis E virus infection.

Hepatitis E virus (HEV) is mainly transmitted orally, either waterborne or zoonotic foodborne. Intestinal viruses such as rotavirus are known to induce type III interferon (IFN) in the gastrointestinal (GI) tract where type III IFN dominantly functions in comparison with type I IFN. Therefore, the aim of this study is to investigate the significance of type III IFN (IFN-λ3) in acute hepatitis E.

Pyruvate carboxylase deficiency type A and type C: characterization of 5 novel pathogenic variants in PC and analysis of the genotype-phenotype correlation.

Pyruvate carboxylase deficiency (PCD) is caused by bi-allelic mutations of the PC gene. The reported clinical spectrum includes a neonatal form with early death (type B), an infantile fatal form (type A), and an late onset form with isolated mild intellectual delay (type C). Apart from homozygous stop-codon mutations leading to type B PCD, a genotype-phenotype correlation has not otherwise been discernible. Indeed, patients harboring bi-allelic heterozygous variants leading to PC activity near zero can pres...
