Think Twice before Interpreting the Skin Prick Test as Age, Body Mass Index, and Atopy Affect Reaction Time and Size.

Int Arch Allergy Immunol 2021 May 4:1-9. Epub 2021 May 4.

Department of Pediatric Allergy and Immunology, Trakya University School of Medicine, Edirne, Turkey.

Introduction: The skin prick test (SPT) is a reliable method to confirm sensitization in IgE-mediated allergic diseases; however, it has been reported to be affected by several personal and environmental factors. Our objective was to determine the factors affecting the skin reactivity to histamine and allergens and investigate whether it differs according to age in terms of reading time.

Methods: A total of 500 patients, aged 4 months-18 years, were enrolled in the study. Read More

Blood mRNA levels of T cells and IgE receptors are novel non-invasive biomarkers for eosinophilic esophagitis (EoE).

Clin Immunol 2021 May 1:108752. Epub 2021 May 1.

John W. Deming Department of Medicine, Section of Pulmonary Diseases, Tulane Eosinophilic Disorder Center (TEDC), Tulane University School of Medicine, New Orleans, LA, USA. Electronic address:

Eosinophilic esophagitis (EoE) is often misdiagnosed as GERD; therefore, the goal of the current study is to establish a non-invasive diagnostic and monitoring biomarker that differentiated GERD from EoE. Reports indicates that IL-15 responsive iNKT cells and tissue specific IgE have a critical in EoE pathogenesis, not in GERD. Therefore, we tested the hypothesized that the panel of IL-15-responsive T cell and IgE receptors may be novel non-invasive biomarkers for EoE. Read More

J Clin Invest 2021 May 4. Epub 2021 May 4.

Department of Medicine, University of Cape Town, Cape Town, South Africa.

T cells are involved in control of COVID-19, but limited knowledge is available on the relationship between antigen-specific T cell response and disease severity. Here, we assessed the magnitude, function and phenotype of SARS-CoV-2-specific CD4 T cells in 95 hospitalized COVID-19 patients (38 of them being HIV-1 and/or tuberculosis (TB) co-infected) and 38 non-COVID-19 patients, using flow cytometry. We showed that SARS-CoV-2-specific CD4 T cell attributes, rather than magnitude, associates with disease severity, with severe disease being characterized by poor polyfunctional potential, reduced proliferation capacity and enhanced HLA-DR expression.

A positive feedback loop reinforces the allergic immune response in human peanut allergy.

J Exp Med 2021 Jul 4;218(7). Epub 2021 May 4.

Sean N. Parker Center for Allergy & Asthma Research at Stanford University and Division of Pulmonary, Allergy, and Critical Care Medicine, Stanford, CA.

Food allergies are a leading cause of anaphylaxis, and cellular mechanisms involving antigen presentation likely play key roles in their pathogenesis. However, little is known about the response of specific antigen-presenting cell (APC) subsets to food allergens in the setting of food allergies. Here, we show that in peanut-allergic humans, peanut allergen drives the differentiation of CD209+ monocyte-derived dendritic cells (DCs) and CD23+ (FcєRII) myeloid dendritic cells through the action of allergen-specific CD4+ T cells.

J Peter

S Afr Med J 2021 Feb 8;111(4):291-294. Epub 2021 Feb 8.

Division of Allergy and Clinical Immunology, Department of Medicine, Faculty of Health Sciences, University of Cape Town, South Africa; Allergy and Immunology Unit, University of Cape Town Lung Institute, South Africa.

As South Africa continues to battle the second wave of SARS-CoV-2 infections, the imminent arrival of vaccines against COVID-19 offers hope. Vaccine roll-out has been accompanied by heightened media coverage that has created both excitement and anxiety, reporting on the shortened timeline of vaccine trials and approvals, as well as the recent series of anaphylaxis cases associated with the two approved mRNA COVID-19 vaccines. Patients with allergic and other immune-based diseases are subgroups especially concerned about vaccine safety and efficacy. Read More

Emerging role of interleukin-13 in cardiovascular diseases: A ray of hope.

J Cell Mol Med 2021 May 4. Epub 2021 May 4.

Department of Cardiology, The Second Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, China.

Despite the great progress made in the treatment for cardiovascular diseases (CVDs), the morbidity and mortality of CVDs remains high due to the lack of effective treatment strategy. Inflammation is a central pathophysiological feature of the heart in response to both acute and chronic injury, while the molecular basis and underlying mechanisms remains obscure. Interleukin (IL)-13, a pro-inflammatory cytokine, has been known as a critical mediator in allergy and asthma. Read More

Conventional Dorsal Root Ganglion Stimulation in an Experimental Model of Painful Diabetic Peripheral Neuropathy: A Quantitative Immunocytochemical Analysis of Intracellular γ-Aminobutyric Acid in Dorsal Root Ganglion Neurons.

Neuromodulation 2021 May 4. Epub 2021 May 4.

Department of Anesthesiology and Pain Management, Maastricht University Medical Centre (MUMC+), Maastricht, The Netherlands.

Background And Objective: The sensory cell somata in the DRG contain all equipment necessary for extensive GABAergic signaling and are able to release GABA upon depolarization. With this study, we hypothesize that pain relief induced by conventional dorsal root ganglion stimulation (Con-DRGS) in animals with experimental painful diabetic peripheral neuropathy is related to the release of GABA from DRG neurons. With use of quantitative immunocytochemistry, we hypothesize DRGS to result in a decreased intensity of intracellular GABA-immunostaining in DRG somata. Read More

Short and dysfunctional telomeres protect from allergen-induced airway inflammation.

Aging Cell 2021 May 4:e13352. Epub 2021 May 4.

Telomeres and Telomerase Group, Molecular Oncology Program, Spanish National Cancer Centre (CNIO), Madrid, Spain.

Asthma is a chronic inflammatory disease affecting 300 million people worldwide. As telomere shortening is a well-established hallmark of aging and that asthma incidence decreases with age, here we aimed to study the role of short telomeres in asthma pathobiology. To this end, wild-type and telomerase-deficient mice with short telomeres (third-generation (G3 Tert mice)) were challenged with intranasal house dust mite (HDM) extract. Read More

A human-airway-on-a-chip for the rapid identification of candidate antiviral therapeutics and prophylactics.

Nat Biomed Eng 2021 May 3. Epub 2021 May 3.

Wyss Institute for Biologically Inspired Engineering, Harvard University, Boston, MA, USA.

The rapid repurposing of antivirals is particularly pressing during pandemics. However, rapid assays for assessing candidate drugs typically involve in vitro screens and cell lines that do not recapitulate human physiology at the tissue and organ levels. Here we show that a microfluidic bronchial-airway-on-a-chip lined by highly differentiated human bronchial-airway epithelium and pulmonary endothelium can model viral infection, strain-dependent virulence, cytokine production and the recruitment of circulating immune cells.
