Special Issue Information

Dear Colleagues,

You are invited to contribute research on calprotectin, a pleiotropic molecule released in both acute and chronic inflammation, is a heterodimer of two mammalian calcium-binding proteins and is released from the cytoplasm of neutrophil granulocytes upon their activation. Calprotectin (S100A9/S100A8) is a member of the S100 protein family. Calprotectin, as a proinflammatory factor of innate immunity, is related to the endogenous damage-associated molecular pattern (DAMP) molecule via Toll-like receptor 4 activation.

Determination of calprotectin is a valuable clinical biomarker of inflammation. In inflammatory gastro-intestinal diseases, colonoscopy and histopathologic evaluation of bowel biopsy specimens are usually regarded as the gold standards for diagnosis and management of such diseases. However, colonoscopy and colon biopsy are not only costly, but occasionally associated with complications. Since fecal calprotectin may serve as a potential surrogate marker for colonoscopy, several clinical studies have focused on this issue. Furthermore, calprotectin may serve as a biomarker of disease activity in rheumatoid arthritis. Plasma calprotectin seems to be a promising biomarker in respiratory infections, allowing more precise diagnosis and selective use of antibiotics compared to other biomarkers. In critically ill patients with bacterial infections, plasma calprotectin seems to be a useful biomarker. Based on these findings, a health economic analysis of the predictive use of plasma calprotectin indicates that this biomarker has cost-saving and life-saving impacts. Calprotectin may rapidly be analyzed turbidimetrically.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

The management of inflammatory bowel disease (IBD), which is characterized by immunodeficiency, has attracted increasing attention, highlighting the necessity for more precise and streamlined diagnostic approaches in clinics. Calprotectin, an immune cell-derived protein with inherent anti-inflammatory and antimicrobial properties, plays a pivotal role in immune regulation and intestinal homeostasis. Its expression levels are intricately linked to IBD activity, enabling differentiation between inflammatory and non-inflammatory states while predicting recurrence risks. As a non-invasive biomarker, fecal calprotectin (FC) and serum calprotectin (SC) analysis offers high reproducibility and clinical utility, facilitating both IBD diagnosis and real-time disease monitoring. Beyond its diagnostic specificity in distinguishing IBD from other gastrointestinal disorders, calprotectin also emerges as a promising therapeutic target, due to its dual role in modulating inflammatory pathways and interacting with the gut microbiota. With collaborative advancements in standardized detection protocols and innovative research methodologies, it is anticipated that calprotectin-based strategies will be integrated into mainstream clinical practice for IBD.
