Special Issue Information

Dear Colleagues,

The human genome contains around 20,000 genes, which can be translated into over 80,000 proteins through alternative splicing. The maintenance and modification of cellular functions are orchestrated by numerous, complex signaling pathways, regulated through these proteins’ direct or indirect interactions. Disease or infections by a pathogen can cause the dysregulation of protein expressions, post-translational modification, or the impairment of their functional involvement in different signaling pathways. These changes in the cellular proteome are eventually reflected in organ-level dysfunction and may lead to severe illness or death.

This Special Issue aims to delve into the critical role proteomics plays in understanding and combating various human diseases and infections. Proteomics is pivotal in elucidating the mechanisms of diseases at the molecular level, offering insights into protein functions, modifications, and interactions within biological contexts. As we uncover the proteome of cells and tissues in health and disease, we gain valuable information that can lead to the identification of biomarkers, therapeutic targets, and a deeper understanding of disease pathogenesis and host–pathogen interactions.

We also want to welcome research on the innovative applications of proteomics in diagnosing, monitoring, and treating human diseases. We encourage submissions that explore the dynamic proteome in various diseases, the interactions between pathogens and host proteomes, and the potential of proteomics in developing novel diagnostic and 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. 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.

Sepsis poses a significant challenge due its lethality, involving multiple organ dysfunction and impaired immune responses. Among several factors affecting sepsis, monocytes play a crucial role; however, their phenotype, proteomic profile, and function in septic shock remain unclear. Our aim was to fully characterize the subpopulations and proteomic profiles of monocytes seen in septic shock cases and discuss their possible impact on the disease. Peripheral blood monocyte subpopulations were phenotype based on CD14/CD16 expression by flow cytometry, and proteins were extracted from the monocytes of individuals with septic shock and healthy controls to identify changes in the global protein expression in these cells. Analysis using 2D-nanoUPLC-UDMSE identified 67 differentially expressed proteins in shock patients compared to controls, in which 44 were upregulated and 23 downregulated. These proteins are involved in monocyte reprogramming, immune dysfunction, severe hypotension, hypo-responsiveness to vasoconstrictors, vasodilation, endothelial dysfunction, vascular injury, and blood clotting, elucidating the disease severity and therapeutic challenges of septic shock. This study identified critical biological targets in monocytes that could serve as potential biomarkers for the diagnosis, prognosis, and treatment of septic shock, providing new insights into the pathophysiology of the disease.
