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

Department of Food, Agriculture and Bioresources, School of Environment, Resources and Development, Asian Institute of Technology, 58 Moo 9, Km. 42, Paholyothin Highway, Klong Luang, Pathumthani 12120, Thailand. Electronic address:

A novel, sensitive and selective electrochemical sensor based on epitope-imprinted polydopamine (PDA) was developed for ovalbumin (OVA) detection. Molecularly imprinted polydopamine was synthesized on an AuNP-coated screen-printed carbon electrode (SPCE) via electropolymerization in the presence of OVA IgE-binding epitope as the template. Key process parameters including template concentration, electropolymerization cycle, pH, time required for template removal and rebinding were optimized. Read More

T cell memory in tissues.

Eur J Immunol 2021 Apr 10. Epub 2021 Apr 10.

Viral Immunobiology, University of Zurich, Zurich, Switzerland.

Immunological memory equips our immune system to respond faster and more effectively against reinfections. This acquired immunity was originally attributed to long-lived, memory T and B cells with body wide access to peripheral and secondary lymphoid tissues. In recent years, it has been realized that both innate and adaptive immunity to a large degree depends on resident immune cells that act locally in barrier tissues, including tissue resident memory T cells (Trm).

The role of mast cells in the gut and brain.

Giovanna Traina

J Integr Neurosci 2021 Mar;20(1):185-196

Department of Pharmaceutical Sciences, University of Perugia, 06126 Perugia, Italy.

Mast cells are the major effectors in allergic reactions through degranulation and release of inflammatory, vasoactive and nociceptive mediators associated with the pathogenesis of a variety of inflammatory disorders. Mast cells are strategically positioned as gatekeepers at host/environment interfaces, like the skin, airways, gastrointestinal and urogenital tracts, and their presence also in the brain allows them to act not only as sentinels of invading microorganisms but also as targets to respond to different allergens, pathogens and other dangerous agents that can be ingested, inhaled or encountered after the breakdown of the epithelial barrier. Mast cells can respond to any change in the environment by communicating with the different cells involved in the immune response and giving rise to an amplification signal network through feedback loops.

Association of interleukin-12B rs6887695 with susceptibility to allergic rhinitis.

Immunol Res 2021 Apr 8. Epub 2021 Apr 8.

Department of Immunology, School of Medicine, Kermanshah University of Medical Sciences, Kermanshah, Iran.

Interleukin-12 (IL-12) is a heterodimeric cytokine encoded by two separate genes, IL12A and IL12B, which may play a regulatory role in allergen-induced inflammation through CD4 T-cell subsets polarization. The aim of this study was to investigate the association of single-nucleotide polymorphisms (SNPs) in the IL12B gene with susceptibility to allergic rhinitis (AR). We performed a case-control study including 130 AR patients and 130 healthy controls to evaluate the possible association between IL12B gene SNPs (rs3212227, rs6887695) and the risk of AR using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.

Effect of fexofenadine hydrochloride on allergic rhinitis aggravated by air pollutants.

ERJ Open Res 2021 Apr 6;7(2). Epub 2021 Apr 6.

Air Pollution Exposure Laboratory, University of British Columbia, Vancouver, BC, Canada.

In recent decades, seasonal allergic rhinitis (SAR) prevalence has increased and recent studies have shown that air pollutants, such as diesel exhaust particles (DEP), can increase inflammatory and allergic biomarkers. The aim of this study was to investigate the effects of DEP on SAR symptoms induced by ragweed and to evaluate the efficacy and safety of fexofenadine HCl 180 mg placebo. This phase 3, single-centre, sequential, parallel-group, double-blind, randomised study (NCT03664882) was conducted in an environmental exposure unit (EEU) during sequential exposures: Period 1 (ragweed pollen alone), Period 2 (ragweed pollen+DEP), and Period 3 (ragweed pollen+DEP+single-dose fexofenadine HCl 180 mg or placebo).
