Special Issue Information

Dear Colleagues,

Since the discovery of the main phytocannabinoids of the cannabis plant and then of the main components of the endocannabinoid system (ECS) (cannabinoid receptors (CB1r and CB2r), endogenous ligands (anandamide and 2-arachidonylglycerol) and both synthetic and metabolic enzymes) the wide distribution of this neuromodulatory system and its crucial involvement in the functional regulation of the central nervous system have become apparent. In this sense, there has been significant interest in recent decades in identifying and understanding the role of the ECS in physiological conditions and how it is altered in various psychiatric, neurological and addictive disorders. Similarly, emphasis has been placed on understanding the effects of functional manipulation of this system through phytocannabinoids and synthetic cannabinoids, focusing on the potential therapeutic benefits that could be derived for treating brain diseases.

Thus, it is crucial to learn more about the ECS-related molecular mechanisms involved to identify the targets that could play a relevant role, as well as the opportunities that this knowledge would offer in developing new therapeutic strategies based on the modulation of the different components that make up the ECS. In this sense, this Special Issue aims to collect original articles (basic or clinical) and reviews (narrative or systematic) that focus on molecular research, providing new insights about the role of the ECS in physiological or pathological conditions from a translational point of view through preclinical and/or clinical data.

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.

Given the high prevalence of cannabis use among people with HIV (PWH) and its potential to modulate immune responses and reduce inflammation, this systematic review examines preclinical evidence on how tetrahydrocannabinol (THC), a key compound in cannabis, affects gene and micro-RNA expression in simian immunodeficiency virus (SIV)-infected macaques and HIV-infected human cells. Through a comprehensive search, 19 studies were identified, primarily involving SIV-infected macaques, with a pooled sample size of 176, though methodological quality varied across the studies. Pathway analysis of differentially expressed genes (DEGs) and miRNAs associated with THC revealed enrichment in pathways related to inflammation, epithelial cell proliferation, and adhesion. Notably, some DEGs were targets of the differentially expressed miRNAs, suggesting that epigenetic regulation may contribute to THC’s effects on gene function. These findings indicate that THC may help mitigate chronic immune activation in HIV infection by altering gene and miRNA expression, suggesting its potential immunomodulatory role. However, the evidence is constrained by small sample sizes and inconsistencies across studies. Further research employing advanced methodologies and larger cohorts is essential to confirm THC’s potential as a complementary therapy for PWH and fully elucidate the underlying mechanisms, which could inform targeted interventions to harness its immunomodulatory effects.
