Special Issue Information

Dear Colleagues,

Previously, the pathogenic mechanism of allergy was thought to be an acquired immune response to antigens. However, Moro et al. discovered group 2 innate lymphoid cells (ILC2), which are leukocytes of the innate immune system and are activated by alarmins rather thanantigens, producing type 2 cytokines such as IL-4, IL-5, IL-13 and IL-31, which are involved in the pathogenesis of various type 2 inflammatory and allergic diseases, including atopic dermatitis. Antibody therapy against type 2 cytokines and alarmins has been applied in clinical practice. However, the mechanisms that regulate alarmin itself and how to effectively suppress ILC remain to be elucidated. In addition, the number of papers on ILC and alarmin is still small, despite the attention they have attracted. In this Special Issue, we would like to publish articles that may provide new discoveries, hopes and surprises regarding ILCs, alarmins and allergic diseases.

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. Biomolecules 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 2700 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.

Asthma is defined as a chronic respiratory disease, the processes of which are mainly related to the hyperreactivity of the immune system. Airway hyperresponsiveness and remodeling are other hallmarks of asthma that are strongly involved in the progression of the disease. Moreover, asthma is associated with the occurrence of atopic dermatitis, chronic sinusitis, allergic rhinitis, and a high profile of T2-type cytokines, such as IL-4, IL-5 and IL-13. The hyperresponsiveness of the immune system is a consequence of aberrant levels of alarmins, endogenous molecules that induce pro-inflammatory responses. They are released as a result of a defect or cell death, leading to the initiation of an inflammatory reaction. High-mobility group box 1 (HMGB1), S100 proteins, interleukin-33 (IL-33), thymic stromal lymphopoietin (TSLP), and IL-25 bind to various receptors, influencing the behavior of immune cells, resulting in stimulated migration and activation of these cells. In this review, we will discuss the potential role of alarmins in the pathogenesis of asthma. Full article
