Histamine research advancements in the second year of the COVID-19 pandemic: report of the European Histamine Research Society (EHRS)

In the light of cancellation of the 50th Annual Meeting of the European Histamine Research Society (EHRS) due to continuing challenges and restrictions imposed by the coronavirus disease 2019 (COVID-19) outbreak, the EHRS Council decided to organize a series of online events spread in 2021 to allow dissemination of histamine research progress and advancement among the Society members and beyond. This report summarizes the outcomes of the EHRS Council initiative that comprised the organization of four webinars, each focusing on a highly relevant histamine research scientific area. These included insights into novel therapeutic targets related to the histaminergic system in the eye, histamine intolerance, and the role of histamine and the histaminergic system in the regulation of the nervous system, as well as an update on studies leading to the development of novel methods for histamine detection. The outcome of this series of virtual events conformed that histamine research continued to develop despite the pandemic, and we witnessed stimulating advancements in 2021. Importantly, the EHRS Council brought histaminologists together in this unprecedented time.
