Special Issue Information
Dear Colleagues,
Long COVID, a persistent multisystem condition following COVID-19 infection, poses significant challenges for medical practitioners and researchers. Despite the growing number of affected individuals, the mechanisms underlying long COVID's pathophysiology remain unclear. While organ damage from the acute infection phase likely accounts for some symptoms, specific long-lasting inflammatory mechanisms have also been proposed.
This Special Issue aims to explore the enigmatic pathophysiological mechanisms of long COVID, focusing on different levels of the relationship between the nervous and immune systems and analyzing broader categories that may offer insights into potential therapeutic interventions. Researchers are invited to contribute their work on diverse aspects of long COVID to advance our understanding and management of this challenging condition.
Key Points:
- Immunological dysregulation: investigating the immune system's role in long COVID, including acquired immune deficiency, auto-immunity, and potential persistent viral presence;
- Persistent inflammatory processes: addressing the potential mechanisms of organ damage from the acute infection phase and investigating persistent inflammatory processes as contributors to long COVID;
- Neurological aspects of the pathogenesis of long COVID associated with an imbalance in the action of various neurotransmitters and inflammatory mediators in the central nervous system;
- The relationship between disturbances of the gut microbiome, gut barrier function and blood-brain barrier dysfunction in the pathogenesis of long COVID;
- Molecular mechanisms of dysfunction of the limbic–reticular–hypothalamic complex and the hypothalamic–pituitary–adrenal axis in the manifestations of long COVID and its complications;
- Autonomic nervous system dysfunction: Investigating autonomic nervous system damage as a possible explanation for various long COVID symptoms, even without clear evidence of organ damage;
- Multisystem nature of long COVID: the role of comorbidities and low-grade chronic systemic inflammation in the development of multiple organ dysfunction as manifestations of post-COVID syndrome.
This Special Issue seeks to consolidate research on these broader mechanisms underlying long COVID, offering a comprehensive understanding of the condition's complexities and paving the way for potential therapeutic avenues. Researchers are invited to contribute their work on these topics to advance our comprehension and management of this challenging condition.

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.
