Psoriasis localization patterns in the Swiss Psoriasis Registry (SDNTT) over 11 years: an analysis by sex and age.

Real-world data on anatomically localized psoriasis and its response to systemic therapy across different age-groups and sexes is limited. This study aimed to evaluate the severity and distribution of psoriasis over time in female and male patients receiving systemic therapies, categorized by age within the Swiss psoriasis registry (SDNTT). Patient-data was obtained over 11 years through the SDNTT.

Synthetic mRNAs Containing Minimalistic Untranslated Regions Are Highly Functional In Vitro and In Vivo.

Synthetic mRNA produced by in vitro transcription (ivt mRNA) is the active pharmaceutical ingredient of approved anti-COVID-19 vaccines and of many drugs under development. Such synthetic mRNA typically contains several hundred bases of non-coding "untranslated" regions (UTRs) that are involved in the stabilization and translation of the mRNA. However, UTRs are often complex structures, which may complicate the entire production process.

Differential functionality of fluoropyrimidine nucleosides for safe cancer therapy.

Chemotherapies are standard care for most cancer types. Pyrimidine analogs including 5-fluorouracil, cytosine arabinoside, 5-azacytidine, and gemcitabine are effective drugs that are utilized as part of a number of anticancer regimens. However, their lack of cell-specificity results in severe side effects.

Molecular aspects of Interleukin-36 cytokine activation and regulation.

Interleukin-36 (IL-36) cytokines are structurally similar to other Interleukin-1 superfamily members and are essential to convey inflammatory responses at epithelial barriers including the skin, lung, and gut. Due to their potent effects on immune cells, IL-36 cytokine activation is regulated on multiple levels, from expression and activation to receptor binding. Different IL-36 isoforms convey specific responses as a consequence of particular danger- or pathogen-associated molecular patterns.

A Basic Method for Formulating mRNA-Lipid Nanoparticle Vaccines in the Lab.

During recent years, RNA therapeutics have begun to make a substantial impact in the clinic, with the approval of the siRNA-based therapeutic Patisiran in 2018, and of the two mRNA SARS-CoV-2 vaccines, BNT162b2 and mRNA-1273 in 2021. A key to the success of these therapeutics lies in the lipid-based delivery system. The therapeutic RNAs are encapsulated in lipid nanoparticles (LNPs), which protect against enzymatic degradation and efficiently deliver the RNA across the cell membrane into the cytosol.

Design and Synthesis of Circular RNA Expression Vectors.

The recent success of the synthetic mRNA-based anti-COVID-19 vaccines has demonstrated the broad potential of the mRNA platform for applications in medicine, thanks to the combined efforts of a small community that has vastly improved key determinants such as design and formulation of synthetic mRNA during the past three decades. However, the cost of production and sensitivity to enzymatic degradation are still limiting the broader application of synthetic mRNA for therapeutic applications. The increased interest in mRNA-based technologies has spurred a renaissance for circular RNA (circRNA), as the lack of free 5' and 3' ends substantially increases resistance against enzymatic degradation in biological systems and does not require expensive cap analogs, as translation is controlled by an Internal Ribosome Entry Site (IRES) sequence.

A murine model of peanut-allergic asthma.

Objectives: Peanut allergy is an IgE-mediated food allergy that is associated with asthma in certain patients. With increasing prevalence, its great impact on the quality of life, and a lack of treatment options, the need for new therapy options is a given. Hence, models for research and development are required.

How to hit the allergy target: A critical appraisal of intralymphatic immunotherapy with practical recommendations on ultrasound-guided injections.

Background: Intralymphatic immunotherapy (ILIT) represents a promising novel approach treating allergic diseases. However, no standardized procedures or recommendations have been established or reported, despite the recognized fact that treatment efficacy relies on the ability to inject the allergen intranodally.

Objective: We aim to provide a critical appraisal of ILIT as a method of allergen immunotherapy and to deliver practical recommendations for accurate ILIT.

Quality of life in allergic rhinitis patients treated with intralymphatic immunotherapy (ILIT): A 19-year follow-up.

Background: In 2002-2005, we conducted a phase I/II clinical trial where a new allergy immunotherapy (AIT) route was introduced: intralymphatic immunotherapy (ILIT). Ultrasound guidance allowed injection of allergen directly into inguinal lymph nodes. Grass pollen-allergic patients received 3 injections with 1-month intervals.

Inflammation in acute myocardial infarction: the good, the bad and the ugly.

Convergent experimental and clinical evidence have established the pathophysiological importance of pro-inflammatory pathways in coronary artery disease. Notably, the interest in treating inflammation in patients suffering acute myocardial infarction (AMI) is now expanding from its chronic aspects to the acute setting. Few large outcome trials have proven the benefits of anti-inflammatory therapies on cardiovascular outcomes by targeting the residual inflammatory risk (RIR), i.

Potential Cost Savings by Switching from Subcutaneous to Intralymphatic Insect Venom Immunotherapy.

Introduction: IgE-mediated bee venom allergy can be treated with allergen-specific immunotherapy (AIT). Subcutaneous immunotherapy (SCIT) is time and cost intensive due to the repeated consultations, but the costs are justified by the high risk of potentially life-threatening allergic reactions, including anaphylaxis. However, intralymphatic immunotherapy (ILIT) offers potential to reduce treatment costs due to a significant reduction in injections and a shorter duration of therapy.

Allergen immunotherapy: progress and future outlook.

Introduction: Allergy, the immunological hypersensitivity to innocuous environmental compounds, is a global health problem. The disease triggers, allergens, are mostly proteins contained in various natural sources such as plant pollen, animal dander, dust mites, foods, fungi, and insect venoms. Allergies can manifest with a wide range of symptoms in various organs and be anything from just tedious to life-threatening.

The next generation virus-like particle platform for the treatment of peanut allergy.

Background: Allergy to peanut is one of the leading causes of anaphylactic reactions among food allergic patients. Immunization against peanut allergy with a safe and protective vaccine holds a promise to induce durable protection against anaphylaxis caused by exposure to peanut. A novel vaccine candidate (VLP Peanut), based on virus-like particles (VLPs), is described here for the treatment of peanut allergy.

Targeting Ara h 2 with human-derived monoclonal antibodies prevents peanut-induced anaphylaxis in mice.

Background: Peanut allergy is a type-I hypersensitivity immune reaction mediated by the binding of peanut allergens to IgE-FcεRI complexes on mast cells and basophils and by their subsequent cellular degranulation. Of all major peanut allergens, Ara h 2 is considered the most anaphylactic. With few options but allergen avoidance, effective treatment of allergic patients is needed.

Strain matters in mouse models of peanut-allergic anaphylaxis: Systemic IgE-dependent and Ara h 2-dominant sensitization in C3H mice.

Background: Peanut allergy accounts for the majority of food-induced hypersensitivity reactions and can lead to lethal anaphylaxis. Animal models can provide an insight into the immune mechanisms responsible for sensitization and allergic anaphylaxis. However, different mouse strains and sensitization protocols can influence the successful development of a peanut allergic mouse model.

RNA with chemotherapeutic base analogues as a dual-functional anti-cancer drug.

Nanoparticles of different sizes formulated with unmodified RNA and Protamine differentially engage Toll-like Receptors (TLRs) and activate innate immune responses . Here, we report that similar differential immunostimulation that depends on the nanoparticle sizes is induced in wild type as well as in humanized mice. In addition, we found that the schedule of injections strongly affects the magnitude of the immune response.

Intralymphatic Immunotherapy (ILIT) With Bee Venom Allergens: A Clinical Proof-of-Concept Study and the Very First ILIT in Humans.

Background: Subcutaneous venom immunotherapy (VIT) represents an effective treatment against bee venom allergy. However, it involves long treatment times, high costs, and the risk of adverse events (AEs). Shorter, safer, and cheaper treatment options are therefore pursued.

Photochemically-Mediated Inflammation and Cross-Presentation of BCG Proteins Stimulates Strong CD4 and CD8 T-Cell Responses in Mice.

Conventional vaccines are very efficient in the prevention of bacterial infections caused by extracellular pathogens due to effective stimulation of pathogen-specific antibodies. In contrast, considering that intracellular surveillance by antibodies is not possible, they are typically less effective in preventing or treating infections caused by intracellular pathogens such as . The objective of the current study was to use so-called photochemical internalization (PCI) to deliver a live bacterial vaccine to the cytosol of antigen-presenting cells (APCs) for the purpose of stimulating major histocompatibility complex (MHC) I-restricted CD8 T-cell responses.

Kinetics and persistence of anti-SARS-CoV-2 neutralisation and antibodies after BNT162b2 vaccination in a Swiss cohort.

Introduction: Since the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), substantial effort has been made to gain knowledge about the immunity elicited by infection or vaccination.

Methods: We studied the kinetics of antibodies and virus neutralisation induced by vaccination with BNT162b2 in a Swiss cohort of SARS-CoV-2 naïve (n = 40) and convalescent (n = 9) persons. Blood sera were analysed in a live virus neutralisation assay and specific IgG and IgA levels were measured by enzyme-linked immunoassay and analysed by descriptive statistics.

Dogmas, challenges, and promises in phase III allergen immunotherapy studies.

The concept of treatment of an allergy with the offending allergen was introduced more than a century ago. Allergen immunotherapy (AIT) is the only disease modifying treatment of allergic diseases caused by inhalational allergens and insect venoms. Despite this, only few AIT products have reached licensure in the US or an official marketing authorization status in European countries.
