Special Issue Information

Dear Colleagues,

Increasing evidence highlights the crucial role of inflammation in pregnancy, influencing maternal and fetal health through complex immune interactions and molecular pathways. Recent studies indicate that dysregulated inflammatory responses contribute to various pregnancy complications, including preeclampsia, preterm birth, and fetal growth restriction, with potential long-term effects on maternal and offspring health, such as cardiovascular, renal, and neurocognitive disorders. Advances in multiomic technologies, including genomics, transcriptomics, proteomics, and metabolomics, have provided new insights into the mechanisms underlying these conditions. The maternal–fetal interface, a key site of immune crosstalk, is now being explored through single-cell and spatial technologies, uncovering dynamic interactions that shape pregnancy outcomes. Moreover, epigenetic modifications and microbiome alterations have emerged as critical regulators of fetal programming, linking maternal immune status to offspring disease susceptibility. This Special Issue will focus on the molecular mechanisms behind, as well as multiomic insights into, pregnancy-induced inflammation, welcoming studies that explore inflammatory pathways, immune regulation, and precision medicine approaches aimed at mitigating pregnancy-related complications.

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 250 words) can be sent to the Editorial Office for assessment.

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.

Preeclampsia (PE), new-onset hypertension during pregnancy, is associated with chronic inflammation both in the placenta and systemically. PE is characterized by placental ischemia, which then results in the production and release of anti-angiogenic factors and inflammatory mediators. Inflammation in PE leads to placental, renal, and vascular damage, which contribute to the phenotype of hypertension and organ dysfunction during pregnancy. T cells, B cells, Natural Killer cells, and macrophages have all been shown to play a role in the inflammation present in the disease. T helper cells contribute to the chronic inflammation in PE. They also activate B cells, which produce agonistic autoantibodies against the angiotensin II type 1 receptor. Natural Killer cells are activated in PE and shift away from decidual Natural killer cells, which produce angiogenic factors, and toward cytotoxic Natural Killer cells, which contribute to tissue damage. Macrophages are polarized towards proinflammatory subtypes and contribute to tissue damage and inflammatory signaling in PE patients. As the immune system plays a role in the pathophysiology of the disease, it may be a potential target for therapeutic intervention to improve maternal and fetal outcomes during and following a PE pregnancy.
