Impact of chronic doxycycline treatment in a mouse model of tauopathy

Ramiro Clerici-Delville, Javier Muñiz, Indiana Páez-Paz, Carolina Lucía Facal et autres

Tauopathies are neurodegenerative disorders characterized by the accumulation of hyperphosphorylated tau, leading to synaptic dysfunction, neuroinflammation, and both cognitive and motor impairments. Doxycycline (Doxy), a tetracycline antibiotic commonly used to treat bacterial infections and skin conditions, has also shown some anti-inflammatory and …

DDOX expands the repertoire of tetracyclines for Parkinson’s disease by preventing the cellular uptake and intracellular impact of α-synuclein preformed fibrils

María del Milagro Terán, Rodrigo Hernán Tomas‐Grau, Estefanía Silvana Soliz-Santander, María Laura Guayán et autres

The increasing prevalence of Parkinson's disease (PD) requires innovative multi-targeted disease-modifying therapies to counteract the toxicity associated with the amplification, propagation, and accumulation of alpha-synuclein (α-Syn) aggregates in the brain. Tetracyclines, particularly doxycycline, have demonstrated multimodal neuroprotective effects, both in vitro and …

Protein Coaggregation in Caribbean Atypical Parkinsonism: The Contribution of Annonacin

Florencia González‐Lizárraga, Susana Boluda, José Ruiz Hidalgo, César L. Ávila et autres

AIMS: There is an unexpectedly high proportion of atypical forms of degenerative parkinsonism in the French Caribbean islands. Residents of these islands are thought to be susceptible to Caribbean atypical parkinsonism (CAP) owing to their consumption of Annonaceae plant products containing the …

Uric Acid, the End-Product of Purine Metabolism, Mitigates Tau-Related Abnormalities: Comparison with DOT, a Non-Antibiotic Oxytetracycline Derivative

Bianca Andretto de Mattos, Rodrigo Hernán Tomas‐Grau, T. Fernandes, Florencia González‐Lizárraga et autres

We aimed to simulate tau abnormalities-specifically hyperphosphorylation and aggregation-that are hallmarks of tauopathies, including Alzheimer's disease, to evaluate tau-targeting therapies. To model pathological p-tau accumulation at early disease stages, we exposed mouse cortical cultures to redox-active iron from hemin (Hm), a breakdown …

Description of barriers to the deprescription of inappropriate drugs in French hospitalized geriatric services

Caren Tatiane de David Antoniazzi, X Cnockaert, Patrick P. Michel

In France, drug-related iatrogenesis is considered to be the cause of numerous emergency departments consultations and the onset of many disabling comorbidities in elderly people. Deprescribing potentially inappropriate drugs for the older adults could help prevent this. However studies have shown that …

C9‐Functionalized Doxycycline Analogs as Drug Candidates to Prevent Pathological α‐Synuclein Aggregation and Neuroinflammation in Parkinson's Disease Degeneration

Clémence Rose, Rodrigo Hernán Tomas‐Grau, Brenda Zabala, Patrick P. Michel et autres

Abstract Doxycycline, a semi‐synthetic tetracycline, is a widely used antibiotic for treating mild‐to‐moderate infections, including skin problems. However, its anti‐inflammatory and antioxidant properties, combined with its ability to interfere with α‐synuclein aggregation, make it an attractive candidate for repositioning in Parkinson's disease. …
