Dimethyl fumarate (DMF) is a well-characterized molecule that exhibits immuno-modulatory, anti-inflammatory, and antioxidant properties and that is currently approved for the treatment of psoriasis and multiple sclerosis. Due to its Nrf2-dependent and independent mechanisms of action, DMF has a therapeutic potential much broader than expected. In this comprehensive review, we discuss the state-of-the-art and future perspectives regarding the potential repurposing of DMF in the context of chronic inflammatory diseases of the intestine, such as inflammatory bowel disorders (i.e., Crohn's disease and ulcerative colitis) and celiac disease. DMF's mechanisms of action, as well as an exhaustive analysis of the in vitro/in vivo evidence of its beneficial effects on the intestine and the gut microbiota, together with observational studies on multiple sclerosis patients, are here reported. Based on the collected evidence, we highlight the new potential applications of this molecule in the context of inflammatory and immune-mediated intestinal diseases.

Osteoarthritis (OA) is a degenerative joint disease associated with imbalanced subchondral bone remodeling, and there is currently no curative treatment available. In OA, excessive osteoclast activity leads to bone loss and inflammatory responses. Dimethyl fumarate (DMF), an Nrf2 activator already used in treating psoriasis and multiple sclerosis, may alleviate OA by suppressing oxidative stress and osteoclastogenesis.

Unlabelled: BackgroundTarget trial emulation (TTE) offers a formal framework for causal inference using observational data, but its validity must be evaluated in each research domain by replicating randomised clinical trials (RCTs). We aimed to replicate eight RCTs evaluating the efficacy of disease-modifying therapies (DMTs) in multiple sclerosis (MS) using French registry data.
Methods: This multicentre, retrospective, observational study was conducted using data extracted in December 2023 from the (OFSEP) database.

Vascular endothelial growth factor (VEGF), a pro-angiogenic molecule, supports blood vessel growth during wound healing but also drives pathological neovascularization in blinding eye diseases such as neovascular age-related macular degeneration (nAMD). Dimethyl fumarate (DMFu), an FDA-approved drug for multiple sclerosis, has previously shown promising anti-inflammatory properties in retinal pigment epithelium, a crucial structure disrupted by nAMD. Here, we extend the multi-phenotypic therapeutic potential of DMFu by discerning the anti-angiogenic capabilities of DMFu in choroidal and retinal endothelial cells.

Background: Radiologically Isolated Syndrome (RIS) is defined as incidentally found MRI abnormalities that are radiographically indistinguishable from multiple sclerosis (MS) and is considered a presymptomatic disease state of MS. Age <37 years, infratentorial or spinal cord lesions, gadolinium-enhancing lesions on index imaging, and positive cerebrospinal fluid oligoclonal bands have been identified as risk factors for conversion to MS. There are no existing guidelines regarding the role of disease-modifying therapy (DMT) in RIS patients.

The treatment of osteoporosis and related bone defects remains challenging. This study identifies pyroptosis-driven inflammation as a key disruptor of bone homeostasis. To address this, we develop a magnesium-gelatin composite microsphere scaffold (GelMa/Mg/DMF MS) that exploit pyroptosis blockade and hydrogen-mediated inflammation regulation for osteoporosis treatment.
