Nervous System

The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal and transmit signals between different parts of its body. In most animals the nervous system consists of two parts, central and peripheral. The central nervous system contains the brain and spinal cord.

Cancer and the Nervous System: Tumor Growth, Metastasis, and Neurobiology

Cancer neuroscience reveals a bidirectional relationship in which neural circuits, neurotransmitters, neurotrophic factors, and immune signaling can shape tumor growth, invasion, and metastasis. Tumors can, in turn, remodel nerves and exploit neural pathways, creating new opportunities and challenges for cancer therapy.

Genomics and AI identify a candidate gene behind rare neurodevelopmental disorder

Researchers at Baylor College of Medicine, the Duncan Neurological Research Institute (Duncan NRI) at Texas Children's Hospital, the Texome Project and collaborating institutions have identified variants in gene BRSK1 as a likely diagnosis for individuals with a rare and complex neurodevelopmental disorder who until now had not received an explanation for their condition.

Could the Mediterranean diet protect the brain through the gut?

A narrative review finds that the Mediterranean diet may support brain health through gut microbiome, immune, metabolic, and barrier-related pathways, but direct human evidence that microbiome remodeling mediates neuroprotection remains limited. The proposed mechanisms involve microbial metabolites, reduced inflammatory signaling, stronger intestinal and blood-brain barrier function, and possible effects on processes linked to Alzheimer’s and Parkinson’s diseases.

Heated tobacco users had more hypertension, but the story is not that simple

A large Japanese real-world cohort study found that current heated tobacco product users had a higher risk of developing hypertension than never-smokers in the primary adjusted analysis. However, the association weakened in several sensitivity analyses, and the observational study could not separate the effects of current heated tobacco use from previous cigarette exposure.

Neuromedin U drives immune suppression in aggressive prostate cancer

A new study from The Wistar Institute has found a link between the nervous system and the rapid development of neuroendocrine prostate cancer (NEPC), an aggressive form of the disease.

Kidney rhythm mismatch linked to dangerous nighttime high blood pressure

Most people's blood pressure falls by 10 to 20 per cent while they sleep, giving the heart and blood vessels a chance to recover. But for some people, that nighttime dip never happens.

Advances in chemistry and delivery are taking oligonucleotide medicines beyond rare diseases

A review in Cell Reports Medicine examines how advances in oligonucleotide chemistry and delivery have established ASOs and RNA interference therapies as a class of genetic medicines, with 21 oligonucleotides approved at the time of writing. It also identifies extrahepatic delivery, safety, target validation, individualized treatment, and data quality as priorities as the field expands into common diseases and explores AI-assisted development.

Menopause leaves a blood protein signature linked to brain aging and Alzheimer’s risk

Researchers identified a 16-protein blood signature associated with menopause that tracked more strongly with reproductive hormones than chronological age and was largely replicated in an independent UK Biobank cohort. Higher menopause proteomic scores were also associated with less favorable proteomic aging estimates and poorer cognitive outcomes in older women, including incident Alzheimer’s dementia, although the observational evidence does not establish causality.
