The Concept of Pathogenic TH2 Cells: Collegium Internationale Allergologicum Update 2021.

Int Arch Allergy Immunol 2021 Apr 12;182(5):365-380. Epub 2021 Apr 12.

Department of Dermatology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland.

T helper (TH) cells have evolved into distinct subsets that mediate specific immune responses to protect the host against a myriad of infectious and noninfectious challenges. However, if dysregulated, TH-cell subsets can cause inflammatory disease. Emerging evidence now suggests that human allergic disease is caused by a distinct subpopulation of pathogenic TH2 cells.

T helper 2-driven immune dysfunction in chronic arsenic-exposed individuals and its link to the features of allergic asthma.

Toxicol Appl Pharmacol 2021 Apr 9:115532. Epub 2021 Apr 9.

Department of Biochemistry and Molecular Biology, University of Rajshahi, Rajshahi 6205, Bangladesh. Electronic address:

Limited information is available regarding the effects of arsenic exposure on immune function. We have recently reported that chronic exposure to As was associated asthma, as determined by spirometry and respiratory symptoms. Because T helper 2 (Th2)-driven immune responses are implicated in the pathogenesis of allergic diseases, including asthma, we studied the associations of serum Th1 and Th2 mediators with the As exposure markers and the features of asthma among individuals exposed to As.

Sapropterin (BH4) Aggravates Autoimmune Encephalomyelitis in Mice.

Neurotherapeutics 2021 Apr 12. Epub 2021 Apr 12.

Institute of Clinical Pharmacology, Medical Faculty, Goethe-University, Frankfurt, Germany.

Depletion of the enzyme cofactor, tetrahydrobiopterin (BH4), in T-cells was shown to prevent their proliferation upon receptor stimulation in models of allergic inflammation in mice, suggesting that BH4 drives autoimmunity. Hence, the clinically available BH4 drug (sapropterin) might increase the risk of autoimmune diseases. The present study assessed the implications for multiple sclerosis (MS) as an exemplary CNS autoimmune disease. Read More

Boosting Nitric Oxide in Stress and Respiratory Infection: Potential Relevance for Asthma and COVID-19.

Brain Behav Immun Health 2021 Apr 5:100255. Epub 2021 Apr 5.

Department of Psychology and Neuroscience, Baylor University, One Bear Place, 97334, Baylor Sciences Building, Suite B.309, Waco, TX, USA.

Nitric oxide (NO) is a ubiquitous signaling molecule that is critical for supporting a plethora of processes in biological organisms. Among these, its role in the innate immune system as a first line of defense against pathogens has received less attention. In asthma, levels of exhaled NO have been utilized as a window into airway inflammation caused by allergic processes. Read More

RhoA and Cdc42 in T cells: Are they targetable for T cell-mediated inflammatory diseases?

Authors:
Fukun Guo

Precis Clin Med 2021 Mar 7;4(1):56-61. Epub 2021 Jan 7.

Division of Experimental Hematology and Cancer Biology, Children's Hospital Medical Center, Cincinnati, OH 45229, USA.

Many inflammatory diseases are not curable, necessitating a better understanding of their pathobiology that may help identify novel biological targets. RhoA and Cdc42 of Rho family small GTPases regulate a variety of cellular functions such as actin cytoskeletal organization, cell adhesion, migration, proliferation, and survival. Recent characterization of mouse models of conditional gene knockout of RhoA and Cdc42 has revealed their physiological and cell type-specific roles in a number of cell types. Read More

Innovative Systems to Deliver Allergen Powder for Epicutaneous Immunotherapy.

Front Immunol 2021 26;12:647954. Epub 2021 Mar 26.

Wellman Center for Photomedicine, Department of Dermatology, Massachusetts General Hospital, Harvard Medical School, Boston, MA, United States.

Allergy is a disorder owing to hyperimmune responses to a particular kind of substance like food and the disease remains a serious healthcare burden worldwide. This unpleasant and sometimes fatal allergic disease has been tackled vigorously by allergen-specific immunotherapy over a century, but the progress made so far is far from satisfactory for some allergies. Herein, we introduce innovative, allergen powder-based epicutaneous immunotherapies (EPIT), which could potentially serve to generate a new stream of technological possibilities that embrace the features of super safety and efficacious immunotherapy by manipulating the plasticity of the skin immune system sufficient delivery of not only allergens but also tolerogenic adjuvants.

IgE antibodies increase honeybee venom responsiveness and detoxification efficiency of mast cells.

Allergy 2021 Apr 11. Epub 2021 Apr 11.

Dept. of Pathology, Stanford University School of Medicine, Stanford, CA, 94305-5176, USA.

Background: In contrast to theirclearly defined rolesin allergic diseases, the physiologic functions of Immunoglobulin E antibodies (IgEs) and mast cells (MCs) remainenigmatic. Recent research supports the toxin hypothesis,showing thatMCs and IgE-related type 2 immune responses can enhance host defense against certain noxious substances, including honeybee venom (BV).

Relevance of Major Allergens in Weed Pollen Allergy.

Int Arch Allergy Immunol 2021 Apr 9:1-5. Epub 2021 Apr 9.

Department of Otorhinolaryngology, Head and Neck Surgery, Ludwig-Maximilians-University of Munich, Munich, Germany.

Introduction: Weed pollen allergy is an important and in prevalence increasing cause of pollinosis in Europe and across the world. In this study we focus on the value of common diagnostic tools for detection of a sensitization to mugwort and English plantain, especially with regard to the clinical relevance of the sensitization.

Methods: Eighty weed pollen sensitized patients (41 to mugwort and 39 to English plantain) were assessed retrospectively regarding their clinical anamnesis, in-vivo tests (skin prick test [SPT] and allergen specific provocation) and in-vitro tests (immunoglobulin E [IgE] reactivity to purified natural allergen extract and specific allergen components in serum).

Surgery 2021 Apr 8. Epub 2021 Apr 8.

University of Colorado Anschutz Medical Campus, Skaggs School of Pharmacy and Pharmaceutical Sciences, Aurora, CO. Electronic address:

Background: Cefazolin is routinely recommended as the first-line agent for surgical antibiotic prophylaxis because it prevents more surgical site infections than second-line antibiotics. Clinicians often avoid administering cefazolin to patients who are labeled as penicillin allergic due to concerns of cross-reactivity. The aim of this study was to compare the incidence of hypersensitivity reactions between cefazolin and the second-line antibiotics vancomycin and clindamycin. Read More

The high affinity IgE receptor: a signaling update.

Curr Opin Immunol 2021 Apr 7;72:51-58. Epub 2021 Apr 7.

Laboratory of Allergic Diseases, Center for Autoimmunity and Inflammation, La Jolla Institute for Immunology, La Jolla, CA 92037, USA; Department of Dermatology, School of Medicine, University of California San Diego, La Jolla, CA 92093, USA.

Here we update receptor proximal and distant signaling events of the mast cell high affinity IgE receptor (FcεRI) launching immediate type I hypersensitivity and an inflammatory cytokine-chemokine cascade. Different physiologic antigen concentrations, their affinity, and valency for the IgE ligand produce distinct intracellular signaling events with different outcomes. Investigating mast cell degranulation has revealed a complex molecular machinery that relays proximal signaling to cytoskeletal reorganization, granule transport and membrane fusion. Read More
