Special Issue Information

Dear Colleagues,

Mammalian brain development involves neuronal proliferation, differentiation, apoptosis, migration, neurite formation, axonal wiring, dendritic arborisation, synaptogenesis, and synaptic sculpting. These events are supported by a variety of glial cells and blood vessels, which are themselves undergoing genesis and maturation. This multifaceted process is orchestrated by cell to cell signalling involving many types of molecules including “immune system” communicators. While the bulk of morphological brain changes occur in fetal to early postnatal life, neuromaturation continues well into the postnatal period allowing the external environment to impact brain wiring through one’s experiences. Thus, early life stress and infection can dramatically alter neurodevelopment by modulating “immune” signalling in the body and brain.

In this Special Issue of Biomolecules called “Impact of Inflammation in Neurodevelopment”, we would like to highlight the emerging role of the immune system in normal and abnormal neurodevelopment. Now is the time to address what is known and what remains to be answered with regard to the influence of the immune system on neurodevelopment, including its role in the pathogenesis and pathophysiology of neurodevelopmental disorders. Of particular interest is the more recently accepted role of the immune system in normal neurodevelopment and how it is utilised during critical periods of neurodevelopment across age. We welcome review articles and primary data papers that investigate the role and consequences of inflammation on neurodevelopment from preconception until adulthood. We invite contributions from diverse disciplines including preclinical, post-mortem brain, and epidemiological studies. The topics and scope of review papers should be confirmed with the guest editors prior to submission to avoid redundancy; alternative approaches to review topics may be suggested.

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. Biomolecules 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 2700 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Adversity during early life, a critical period for brain development, increases vulnerability and can have a lasting impact on the brain and behaviour of a child. However, the long-term effects of cumulative early-life stressors on brain and behaviour are not well known. We studied a 2-hit rat model of early-life adversity using maternal separation (MS) and immune activation (lipopolysaccharide (LPS)). Rat pups underwent MS for 15 (control) or 180 (MS) minutes per day from postnatal day (P)2–14 and were administered saline or LPS (intraperitoneal) on P3. Open-field (OFT) and object-place recognition tests were performed on rat offspring at P33–35 and P42–50, respectively. The pre-frontal cortex (PFC) and hippocampus were removed at the experimental endpoint (P52–55) for mRNA expression. MS induced anxiety-like behaviour in OFT in male and reduced locomotor activity in both male and female offspring. LPS induced a subtle decline in memory in the object-place recognition test in male offspring. MS increased glial fibrillary acidic protein (GFAP) and brain-derived neurotrophic factor expression in PFC and ionised calcium-binding adapter molecule-1 expression in male hippocampus. MS and LPS resulted in distinct behavioural phenotypes in a sex-specific manner. The combination of MS and LPS had a synergistic effect on the anxiety-like behaviour, locomotor activity, and GFAP mRNA expression outcomes. Full article
