Lung tumor-initiating cells (TICs) exhibit a unique ability to switch from glucose to ketone metabolism when faced with glucose deprivation. This metabolic adaptation allows TICs to thrive in nutrient-stressed environments, promoting tumor initiation and growth. Ketone supplementation or adherence to a ketogenic diet enhances TIC growth and their tumor-initiating capacity. Metabolomic, genomic, and flux analyses demonstrate that ketones support ketolysis, fatty acid synthesis, and de novo lipogenesis. Interestingly, the ketogenic diet also exposes TICs to metabolic vulnerabilities, particularly through the inhibition of the monocarboxylate transporter 1 (MCT1) and fatty acid synthase (FASN). Disruption of CD147, the chaperone protein regulating MCT1, leads to the loss of TICs under glucose-limited conditions both in vitro and in vivo. These findings reveal a nutrient-responsive metabolic switch in lung TICs, highlighting the potential of dietary interventions to influence cancer progression and enhance targeted therapy efficacy.

Autologous haematopoietic stem cell transplantation (AHSCT) significantly impacts long-term progression independent of relapse activity (PIRA) in aggressive relapsing-remitting multiple sclerosis (RR-MS). A retrospective propensity-score matched study analyzed 30 RR-MS patients who underwent BEAM/ATG AHSCT compared to 30 controls treated with natalizumab (NTZ) from 2007 to 2018. The median follow-up duration was 106 months. While the cumulative proportion of patients experiencing PIRA during the NTZ treatment epoch showed no significant difference between the two groups (p=0.990), AHSCT demonstrated a lower cumulative proportion of PIRA during the entire follow-up period. These findings highlight the potential of AHSCT to address the unmet need for effective treatment of PIRA in MS, which is only modestly influenced by conventional disease-modifying treatments targeting peripheral adaptive immunity.

A second blood test, Elecsys pTau181, has received approval to assist in diagnosing Alzheimer’s disease. This test measures phosphorylated tau protein levels in blood plasma and demonstrates a 97.9% accuracy in ruling out Alzheimer’s in individuals with cognitive impairments. Developed by Roche and Eli Lilly, the test is the first of its kind approved for primary-care settings. It focuses on negative predictive value, helping to exclude Alzheimer’s rather than confirm it. Another blood test, Lumipulse, was approved earlier and measures the ratio of pTau217 and amyloid-β proteins. Lumipulse has shown a 97% confirmation rate for negative results and 92% for positive results in follow-up diagnostics. Despite their high accuracy, both tests may yield uncertain results in cases where cognitive symptoms are ambiguous, necessitating further testing for a definitive diagnosis.

A second blood test has been been approved by the US Food and Drug Administration to assist in diagnosing Alzheimer’s disease. Will these tests change how cognitive decline is measured?

Intercellular nanotubular networks facilitate material exchange in neurons. Long, thin dendritic filopodia form direct dendrite–dendrite nanotubes (DNTs) in the mammalian cortex. Super-resolution microscopy reveals that DNTs possess an actin-rich composition and dynamic properties, allowing for long-range calcium ion (Ca2+) propagation. Imaging and machine learning analysis confirm that DNTs are anatomically distinct from synaptic spines. DNTs actively transport small molecules and human amyloid-β (Aβ), with DNT density increasing prior to plaque formation in the medial prefrontal cortex of APP/PS1 mice. This suggests a potential role for the dendrite-DNT network in Alzheimer’s disease pathology. Computational models demonstrate that DNT-mediated Aβ propagation can recapitulate early amyloidosis, predicting selective intracellular accumulation. These findings reveal a novel nanotubular connectivity layer in the brain, extending neuronal communication beyond traditional synapses.

Intercellular nanotubular networks mediate material exchange, but their existence in neurons remains to be explored in detail. We identified long, thin dendritic filopodia forming direct dendrite–dendrite nanotubes (DNTs) in mammalian cortex. Super-...

Degenerative disc disease (DDD) is an age-related condition characterized by the breakdown of intervertebral discs, leading to significant pain and reduced quality of life. DDD primarily affects the lower lumbar region, causing discomfort in various areas, including the back, hips, knees, shoulders, and neck. The degeneration process occurs due to micro-injuries from daily activities such as walking, lifting heavy objects, and repetitive movements. These activities lead to damage in chondrocytes and synovial cells, resulting in ineffective lubrication of the joints over time. Consequently, this damage manifests as asymmetric joint space narrowing, osteophyte formation, and subchondral sclerosis. The spinal disc structure includes the nucleus pulposus at its center, encased by the annulus fibrosus. While disc degeneration is a normal aspect of aging, it can become problematic for some individuals, necessitating effective treatment options. Stem cell therapy emerges as a potential intervention to address the underlying causes of DDD and alleviate associated pain.
