Special Issue Information

Dear Colleagues,

Inflammasomes are a topic of growing interest today, as they are biologic entities transversely implicated in the pathogenesis of many acute and chronic inflammation-related diseases. The constitution and cleavage actions of such multi-protein complexes underlie the functioning of the innate response to various inflammatory stimuli. The final result is a particular form of programmed cell death, namely, pyroptosis. In the absence of relevant disorders, inflammasomes such as NLRP3, NAIP/NLRC4, and others act as intracellular ‘sensors’ of exogenous or endogenous aggressions via PAMPs and DAMPs. In autoimmune and oncohaematological diseases, they are perpetually involved and might feed mechanisms of clinical aggravation and progression. Interestingly, there is an undeniable signaling crosstalk linking cytokines activated by inflammasomes to injury-response mechanisms such as coagulation and fibrosis. Recently, inflammasomes have also attracted the attention of researchers because of their relevance in causing acute alveolar damage during SARS-CoV-2 infection. Silencing or mitigating aberrant over-functioning of these complexes could be a turning point for several pathological conditions. For this reason, targeted therapies that may interfere with inflammasome signaling deserve to be thoroughly developed. This Special Issue aims to bring together the main scientific proposals on the subject, covering everything from normal pathophysiology to the most recent clinical and translational findings in inflammatory 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. 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.

Dysregulated inflammatory signaling is a key feature of myeloproliferative neoplasms (MPNs), most notably of myelofibrosis (MF). Indeed, MF is considered the prototype of onco-inflammatory hematologic cancers. While increased levels of circulatory and bone marrow cytokines are a well-established feature of all MPNs, a very recent body of literature is intriguingly pinpointing the selective overexpression of cytokine receptors by MF hematopoietic stem and progenitor cells (HSPCs), which, by contrast, are nearly absent or scarcely expressed in essential thrombocythemia (ET) or polycythemia vera (PV) cells. This new evidence suggests that MF CD34+ cells are uniquely capable of sensing inflammation, and that activation of specific cytokine signaling axes may contribute to the peculiar aggressive phenotype and biological behavior of this disorder. In this review, we will cover the main cytokine systems peculiarly activated in MF and how cytokine receptor targeting is shaping a novel therapeutic avenue in this disease. Full article
