In a somewhat narrow diagnostic lens, Alzheimer disease (AD) has been considered a brain-specific disease characterized by the presence of Aβ (β-amyloid) plaques and tau neural fibrillary tangles and neural inflammation; these pathologies lead to neuronal death and consequently clinical symptoms, such as memory loss, confusion, and impaired cognitive function. However, for decades, researchers have noticed a link between various cardiovascular abnormalities and AD-such as heart failure, coronary artery disease, atrial fibrillation, and vasculopathy. A considerable volume of work has pointed at this head to heart connection, focusing mainly on associations between cerebral hypoperfusion and neuronal degradation. However, new evidence of a possible systemic or metastatic profile to AD calls for further analysis of this connection. Aβ aggregations-biochemically and structurally akin to those found in the typical AD pathology-are now known to be present in the hearts of individuals with idiopathic dilated cardiomyopathy, as well as the hearts of patients with AD. These findings suggest a potential systemic profile of proteinopathies and a new hypothesis for the link between peripheral and central symptoms of heart failure and AD. Herein, we provide an overview of the cardiovascular links to Alzheimer disease.

The development of multifunctional therapeutic agents is crucial for addressing complex diseases such as Alzheimer's disease. Herein, we report a ruthenium-rhenium (Ru-Re) complex that combines photodynamic therapy (PDT) and carbon monoxide (CO) generation capabilities. The Ru-Re complex shows promising photophysical property and significant therapeutic potential.

Palmitoylethanolamide (PEA) is emerging as a promising therapeutic agent for neuropathic and other pain-related conditions. This naturally occurring fatty acid has drawn interest because of its ability to regulate pain and inflammation. Initially identified in food sources, PEA has been the subject of extensive research to elucidate its properties, efficacy, and clinical applications.

Lung adenocarcinoma (LUAD) is a common histologic lung cancer with high morbidity and mortality, and most patients have distant metastases at diagnosis. RasGEF Domain Family Member 1C (RASGEF1C) could regulated Alzheimer's disease. However, its function in various cancers, including LUAD, is poorly understood.

Microglial phagocytosis is a highly energy-consuming process that plays critical roles in clearing neurotoxic amyloid-β (Aβ) in Alzheimer's disease (AD). However, microglial metabolism is defective overall in AD, thereby undermining microglial phagocytic functions. Herein, we repurpose the existing antineoplastic drug lonidamine (LND) conjugated with hollow mesoporous Prussian blue (HMPB) as a "microglial energy modulator" (termed LND@HMPB-T7) for safe and synergistic Aβ clearance.
