Special Issue Information
Dear Colleagues,
Psoriatic arthritis (PsA) is a chronic inflammatory immune-mediated disease that usually involves the skin and several musculoskeletal sites (joint, enthesis, and axial skeleton), and can also extend to the eye (uveitis) and the bowel (bowel inflammatory disease). Furthermore, patients with PsA also show an increase in the prevalence of classical (T2 diabetes, hypertension, metabolic syndrome, obesity) and non-classical (systemic inflammation) cardiovascular risk factors, leading to a rise in morbidity and mortality.
Advances in basic and clinical research in the last two decades have improved our understanding of pathogenesis and helped the development of targeted therapies that provide better control of the disease and improve patients’ quality of life. Genomic and immunological studies in biofluids and synovial tissue of PsA patients have demonstrated two main immune-inflammatory pathways in PsA: TNFalfa and IL-23/IL-17. However, while skin has a higher expression of the IL-23/IL-17-related gene, in synovial tissue, there is higher TNFalfa-related gene expression. This discordance in cytokine expression among different tissues explains the differential therapeutic response between skin and joint to those cytokine inhibitors in PsA. Moreover, around 60% of PsA patients do not achieve significant clinical response (ACR50%) with the current targeted biological and synthetic therapies.
Therefore, addressing clinical heterogeneity and tissue pathogenesis diversity is one important step to better understand the molecular pathways resulting in different PsA endotypes. Finally, the definition of endotypes will inform therapy choice.
This Special Issue focused in “Psoriatic Arthritis: Pathogenesis and Targeted Therapies” will welcome revisions and original articles aiming to understand the link between cellular and molecular expression patterns and clinical heterogeneity, including the response to distinct targeted therapies in PsA. Some suggestions are:
- Transcriptomic, proteomic, or single-cell–RNAseq analysis of the different tissues involved in PsA to gain insights on their molecular diversity and potentially reveal new targets;
- Cytokine expression patterns (at the protein and mRNA level) in biofluids and/or involved tissues and its association with response to therapy;
- Epigenetic (DNA methylation, mirRNA), lipidomics, and other -omic techniques looking at differences of translational/clinical relevance between PsA and rheumatoid arthritis or undifferentiated arthritis;
- Other suggested articles related to the topic.

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.
