These polymorphonuclear leukocytes have a very active metabolism and contain numerous intracellular secretory granules that enable multiple effects on both health and disease status. Classically, eosinophils have been considered important immune cells in the pathogenesis of inflammatory processes (eg, parasitic helminth infections) and allergic or pulmonary diseases (eg, asthma) and are always associated with a type 2 immune response. Furthermore, in recent years, eosinophils have been linked to the immune response by conferring host protection against fungi, bacteria, and viruses, which they recognize through several molecules, such as toll-like receptors and the retinoic acid-inducible gene 1-like receptor. The immune protection provided by eosinophils is exerted through multiple mechanisms and properties. Eosinophils contain numerous cytoplasmatic granules that release cationic proteins, cytokines, chemokines, and other molecules, all of which contribute to their functioning. In addition to the competence of eosinophils as effector cells, their capabilities as antigen-presenting cells enable them to act in multiple situations, thus promoting diverse aspects of the immune response. This review summarizes various aspects of eosinophil biology, with emphasis on the mechanisms used and roles played by eosinophils in host defence against viral infections and response to vaccines.

ARADyAL has proposed a research program organized into 3 different areas focusing on precision medicine, as follows: Program 1, Mechanisms and prediction of adverse drug reactions and allergic diseases; Program 2, Toward a precise diagnosis of allergic diseases; and Program 3, Predicting interventions in allergic diseases. There is also 1 common program dedicated to training.

{"title":"Is Environmental Pollen Concentration a Risk Factor for SARS-CoV-2 Infection?","authors":"A J Moral de Gregorio, R Guzmán Rodríguez, C J Senent Sánchez, J A Lemus Calderón, A Valero Santiago","doi":"10.18176/jiaci.0743","DOIUrl":"https://doi.org/10.18176/jiaci.0743","url":null,"abstract":"To the Editor: Since the new betacoronavirus SARS-CoV-2 [1] emerged in Wuhan, People's Republic of China, in late 2019 and the World Health Organization declared COVID-19 a pandemic on March 11, 2020, the number of cases increased progressively, reaching 153 632 235 million infected and 3 215 270 million dead as at April 30, 2021 [2]. In this context, various publications have linked the SARS-CoV-2 infection rate to the pollen concentration in a specific area, the most recent being that of Damialis et al [3], who reported data on 31 countries around the world. This theory is supported by studies indicating that pollens, regardless of their allergenic potential, possess the ability to suppress antiviral immunity by weakening the immune system’s response to respiratory viruses [4]. At cellular level, the eosinophil, especially in eosinopenia, has been reported to be a relevant factor in COVID-19, although further studies are needed to confirm and clarify its role in this emerging disease [5]. Other articles have also appeared. Hoogeveen et al [6] concluded that pollen is an inverse predictor of respiratory infections, including COVID-19. In our opinion, the statement made by Damialis et al [3] at a global level does not bear any relation to what we have observed in Spain, since, as COVID-19 occurs in waves, a period of pollination may coincide at some point with a certain increase in cases. Therefore, we believe that chance plays a greater role in this relationship than increased pollen concentrations in the environment. In addition, Damialis et al only assess 1 month of pollination, thus potentially inviting bias. Data from a whole year would make for a more interesting assessment. For this reason, we proposed a retrospective longitudinal study to interpret the relationship between daily cases of SARS-CoV-2 infection and the total daily pollen concentration in Spain. To this end, we collected the total daily pollen concentration and the daily incidence of COVID-19 cases in 14 Spanish cities (Madrid, Barcelona, Valencia, Sevilla, La Coruña, Oviedo, Burgos, San Sebastian, Logroño, Zaragoza, Pamplona, Murcia, Toledo, and Cáceres) from March 1, 2020 to February 28, 2021. We chose these cities to ensure a heterogeneous sample of the Spanish population; the dates chosen cover the first year of the pandemic in Spain. Pollen data were collected from the website www.polenes. com of the Aerobiology Network of the Spanish Society of Allergology and Clinical Immunology (SEAIC); the data on infections per city per day were obtained from the website of the Spanish Ministry of Health, Consumption, and Social Welfare. Once these data were available, a Spearman correlation was performed to determine whether there was a significant relationship between total pollen concentrations and cases of SARS-CoV-2 infection. Comparison of the daily cases of COVID-19 with the daily pollen concentration in the cities analyzed yielded a negative correlation coefficient, thus rul","PeriodicalId":520676,"journal":{"name":"Journal of investigational allergology & clinical immunology","volume":" ","pages":"79-80"},"PeriodicalIF":7.2,"publicationDate":"2021-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39392464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
