Special Issue Information
Dear Colleagues,
Eosinophils are both circulating and tissue-resident leukocytes, traditionally regarded as damaging effector cells. Recently, eosinophils have been subdivided into different subpopulations with distinct phenotypes and functions, namely, resident and inflammatory eosinophils. A role for resident eosinophils (rEos) in healthy tissue has been described, including the maintenance of the tissue microenvironment during organ development, along with the modulation of host innate and adaptive immune responses. The other subtype, inflammatory eosinophils (iEos), has been distinguished based on CD62L of membrane expression and is associated with inflammatory responses in patients with severe asthma and nasal polyps. However, growing evidence now reveals a role for eosinophils not only in asthma but also in autoimmune diseases and vasculitis as well as in hypereosinophilic syndromes. Their presence in inflammatory tissues is a hallmark of the type 2 inflammatory response. Eosinophils primed by interleukin (IL)-5, IL-3, granulocyte macrophage colony-stimulating factor (GM-CSF), and eotaxins can express membrane receptors and adhesion molecules involved in activation and tissue migration. Treatment of eosinophilic diseases has traditionally been through nonspecific eosinophil attenuation via the use of glucocorticoids. However, several novel biologic therapies targeting eosinophil maturation factors, such as IL-5 and IL-5R or IL-4/IL-13R, have recently been approved for clinical use. The aim of this Special Issue is to highlight new findings on the physiological and pathophysiological roles of eosinophils in the various pathologies in which they are involved and discuss current and future therapeutic strategies.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biomedicines is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
