Allergic rhinitis, caused by airborne pollen, is a common disease with a great impact on the quality of life for patients and high costs for society. Prevention of high pollen concentrations in the air is relevant for creating a safe environment for allergic patients. Due to climate change, the heat in cities during the summer is a recurring problem. The local climate can be improved by using the cooling properties of trees, providing shade and cooling by evapotranspiration. When deciding which tree species will be planted, it is important to take into account the allergenicity of the pollen that the tree produces. Available guides, used all over the world, on the allergenicity of pollen are very divers in content and interpretation and not applicable for the Netherlands. In this study a method is described to develop a guide for the allergenic potential of tree pollen in a region, in this case the Netherlands. For the most common tree species in the Netherlands the scientific knowledge on the allergenicity of the pollen was collected, followed by an inventory on regional pollen abundance. Subsequently, the sensitization pattern in a patient group with possible inhalation allergy was analyzed. Based on these data allergenicity of the tree pollen was classified into five classes. Eight tree species/genera of the 61 most planted tree species in the Netherlands are considered to have a very strong to moderate allergenic potential. We propose to use this methodology to develop regional-specific guides classifying the allergenic potential of tree pollen.

Parvalbumin (PV), a thermostable and digestion-resistant fish allergen, has been shown to retain its allergenic potential following traditional treatments, thus posing a persistent allergic risk. The study investigated the digestive kinetics and IgE immunoreactivity of Trachinotus ovatus PV, a major fish allergen, under different treatments (untreated; DPCD treatment-15 MPa, 30 min, 50 °C; heat treatment), to evaluate its allergenic potential alterations. The analysis was conducted using a combination of techniques to assess the proteolytic stability and IgE-binding capacity of PV, including Tris-Tricine-SDS-PAGE, Western blot (WB), indirect enzyme-linked immunosorbent assay (ELISA), and free amino group quantification.

Purpose: This review and case report address ligneous conjunctivitis (LC), a rare ocular condition caused by plasminogen deficiency type 1 (PLGD-1), which manifests as wood-like fibrin-rich membranes on the palpebral conjunctiva. The goal is to provide ophthalmologists-often the first physicians to encounter the condition-with a robust understanding of its systemic manifestations and to highlight current therapeutic strategies, with particular emphasis on the administration of intravenous plasminogen concentrate.
Methods: We present a clinical LC case alongside a narrative review of published cases, etiology, and treatment approaches.

There is no vaccine for severe malaria. STEVOR antigens on the surface of -infected red blood cells are implicated in severe malaria and are targeted by neutralizing antibodies, but their epitopes remain unknown. Using computational immunology, we identified highly immunogenic overlapping B- and T-cell epitopes (referred to as multiepitopes, 7-27 amino acids) in the semiconserved domain of four STEVORs linked with severe malaria and clinical immunity.

NSG-SGM3 humanized mouse models are well-suited for studying human immune physiology but are technically challenging and expensive. We previously characterized a simplified NSG-SGM3 mouse, engrafted with human donor CD34 hematopoietic stem cells without receiving prior bone marrow ablation or human secondary lymphoid tissue implantation, that still retains human mast cell- and basophil-dependent passive anaphylaxis responses. Its capacities for human antibody production and human B cell maturation, however, remain unknown.

Animal allergens, particularly those from cats, dogs, and horses, are significant risk factors for the development of allergic diseases in childhood. Managing animal allergies requires allergen avoidance and, when this is not feasible, specific immunotherapy. Patient history remains the cornerstone of diagnosis, providing the foundation for diagnostic algorithms.
