Inhalation of airborne pollen causes irritative symptoms in humans, known as pollinosis. The changing global climate and increased pollution contribute to enhance the release of pollen, thereby increasing the number of people suffering from allergies. We examined the effect of spraying weak alkaline solutions onto cedar trees, the main allergenic culprit in Japan, on pollen release. Weak alkali...

Seasonal Allergies in a Changing Climate Several intertwined factors influence how a plant grows and how much pollen it produces. Projected rises in two of these—regional temperatures and atmospheric CO 2 levels—could mean an increase in the number of people affected by seasonal allergies.

Pollen is responsible for seasonal allergies, such as allergic rhino-conjunctivitis (AR), and has become a growing public health concern. Climate change affects the range of allergenic species well timing length pollen season. In Egypt, data on pollinosis are scarce. This study aimed to identify most prevalent causing allergies among Egyptian patients with respiratory allergies. A total 200 dis...

Pollen is one of the most common causes of allergy worldwide, making the study of their molecular composition crucial for the advancement of allergy research. Despite substantial efforts in this field, it is not yet clear why some plant pollens strongly provoke allergies while others do not. However, proteases and protease inhibitors from allergen sources are known to play an important role in ...

It is estimated that pollen allergies affect approximately 40% of allergic individuals. In general, tree pollen allergies are mainly elicited by allergenic trees belonging to the orders Fagales, Lamiales, Proteales, and Pinales. Over 25 years ago, the gene encoding the major birch pollen allergen Bet v 1 was the first such gene to be cloned and its product characterized. Since that time, 53 tre...

Introduction: Climate change may have an impact of prevalence and severity of respiratory allergies causing changes in the concentrations, distribution, dispersion patterns, and allergenic potential of aeroallergens in the environment. Objective: To assess the prevalence of atopy, sensitization to common pollen allergens, and respiratory allergies (allergic rhinitis and asthma) among adult popu...

weed pollen grains belonging to  the  asteraceae  family contain  a variety of  allergens inducing type i  and iv allergies in susceptible people. the  aim of this research was to compare  the  allergenic properties  of  immature  and  mature  shasta  daisy pollen  grains (chrysanthemum maximum ramond) to define the potential role of the maturation process on the allergenicity of asteraceae pol...

Both humans and their most important domestic animals harbor IgE and a similar IgE receptor repertoire and expression pattern. The same cell types are also involved in the triggering or regulation of allergies, such as mast cells, eosinophils or T-regulatory cells. Translational clinical studies in domestic animals could therefore help cure animal allergies and at the same time gather knowledge...
