Rapid induction of allergen-blocking IgG in dogs vaccinated with plant-based, Der f 2-expressing bioparticles.

Background: Allergen-carrying virus-like particles are effective and safe means of allergen immunotherapy (AIT) in rodent models.

Objective: To study the development of allergen-blocking immunoglobulin (Ig)G in dogs injected with Der f 2-carrying enveloped plant-based bioparticles (eBPs).

Materials And Methods: Laboratory beagle dogs were injected intradermally (ID) or subcutaneously (SC) with Der f 2-eBP three times at 2-week intervals.

Exploring the Potentiality of a Plant Platform for Monoclonal Antibody Production in Veterinary Medicine.

Canine atopic dermatitis (CAD) is an allergic, inflammatory, and pruritic skin disease associated with the production of IgE antibodies against environmental allergens and mainly house dust mite allergens. This complex dermatological pathology involves Interleukin 31 (IL-31) as a central itch mediator. One of the most effective CAD treatments is a caninized monoclonal antibody (mAb) called Lokivetmab.

A novel peanut allergy immunotherapy: Plant-based enveloped Ara h 2 Bioparticles activate dendritic cells and polarize T cell responses to Th1.

Introduction: As the only market-authorized allergen immunotherapy (AIT) for peanut allergy is accompanied by a high risk of side effects and mainly induces robust desensitization without sustained efficacy, novel treatment options are required. Peanut-specific plant-derived Bioparticles (BPs) surface expressing Ara h 2 at high density have been shown to be very hypoallergenic. Here, we assessed the dendritic cell (DC)-activating and T cell polarization capacity of these peanut-specific BPs.

Cerebral MRI abnormalities associated with vigabatrin therapy.

Purpose: Investigate whether patients on vigabatrin demonstrated new-onset and reversible T(2)-weighted magnetic resonance imaging (MRI) abnormalities.

Methods: MRI of patients treated during vigabatrin therapy was reviewed, following detection of new basal ganglia, thalamus, and corpus callosum hyperintensities in an infant treated for infantile spasms. Patients were assessed for age at time of MRI, diagnosis, duration, and dose, MRI findings pre-, on, and postvigabatrin, concomitant medications, and clinical correlation.

Down-regulated expression of plant-specific glycoepitopes in alfalfa.

Compared with other plant expression systems used for pharmaceutical protein production, alfalfa offers the advantage of very homogeneous N-glycosylation. Therefore, this plant was selected for further attempts at glycoengineering. Two main approaches were developed in order to humanize N-glycosylation in alfalfa.

Engineering of a sialic acid synthesis pathway in transgenic plants by expression of bacterial Neu5Ac-synthesizing enzymes.

Plants are a low-cost and contamination-free factory for the production of recombinant pharmaceutical proteins. However, plant-made pharmaceuticals differ from their mammalian homologues by the structure of their N-linked glycans. For instance, most mammalian glycoproteins harbour terminal sialic acids that control their half-life in the bloodstream.
