Researchers discovered vitamin D's mechanism to inhibit inflammation by binding to DNA and activating the MKP-1 gene. Vitamin D levels above 30 ng/ml significantly reduced inflammatory responses.
A new study reveals that bee swarms use inhibitory 'stop signals' to inhibit competing sites and choose the best option, similar to how neurons in human brains make decisions. This mechanism helps avoid costly dithering and ensures a single site is chosen.
Researchers identified a brain-circuit defect that triggers absence seizures, the most common form of childhood epilepsy. The study showed defective signaling between the cerebral cortex and thalamus can produce absence seizures in experimental mice.
Researchers identify pheromone blend that prevents termites from becoming queens, balancing colony population. The discovery reveals crucial role of chemical compounds in regulating termite castes, advancing understanding of insect social behavior and colony management.
Researchers at Burnham Institute for Medical Research discovered that the REDD1 protein is degraded under hypoxic conditions, enabling cells to rapidly restore mTOR signaling. This regulation mechanism plays a crucial role in cellular stress response and may be linked to tumor growth in cancer.
Researchers found that simultaneously inhibiting the mTOR and MAPK signaling pathways enhanced antitumor effects in mouse models of prostate and breast cancer. This dual inhibition was particularly effective against aggressive forms of the disease, leading to a potential breakthrough for combination therapy.
Simultaneous inhibition of two signaling pathways, mTOR and MAPK, resulted in enhanced antitumor effects in mouse models of prostate and breast cancer. This combination therapy may improve the treatment of human cancers, particularly for patients with advanced, hormone-refractory prostate cancer.
Researchers at the University of Texas Medical Branch have developed a potential new therapy for uveitis, an inflammatory eye condition causing 5-15% of all cases of total blindness in the US. The treatment uses an aldose reductase inhibitor to reduce inflammation and is currently being tested in clinical trials.
Scientists at Karolinska Institutet have discovered a mechanism controlling how the brain maintains equilibrium in neuronal activity. A rare cell type, Martinotti cell, acts as a safety device by sending inhibitory signals to surrounding pyramid cells when activated excessively.
Researchers found that adult-born hippocampal neurons have similar properties to mature neurons, including excitatory and inhibitory input responses. This suggests that these cells can form connections indistinguishable from those developed in early life, potentially leading to new treatments for brain disorders.
A study by Martyn Goulding and colleagues reveals that the Notch receptor protein determines whether a single progenitor cell produces excitatory or inhibitory neurons. The researchers found that activated Notch promotes excitatory neuron formation, while low levels of Notch lead to inhibitory neuron development.
Researchers discovered a new way to stop smallpox by inhibiting host cell signaling pathways. Inhibitors already used in human cancer therapy may have widespread applications in treating viral infections and protecting against smallpox.
A defect in neuroligin genes disrupts neuronal connections and results in an imbalance of neuronal function, providing a possible explanation for autistic children's neurodevelopmental defects. Understanding this cellular defect is crucial towards developing therapies for autism-spectrum disorders.
Researchers found B-vitamins to be effective in treating various painful conditions, including neuropathic pain. The study suggests that B1, B6, and B12 inhibit chemical- and heat-induced pain and activate the cGMP-PKG signaling pathway, which contributes to their analgesic effects.
A Cedars-Sinai Medical Center study has discovered a molecular mechanism behind hormonal responses to stress, involving leukemia inhibitory factor (LIF) and its regulation of the pituitary gland. This finding provides new insights into the body's response to stress and sepsis.
Mathematicians at Ohio State University discovered two new electrochemical activity patterns in brain cells, which may help explain normal sleep changes and nervous system disorders like epilepsy. The research reveals that inhibitory signals can produce smooth waves, contrary to previous assumptions.
Researchers have discovered that individual neurons in the brain can be compared to tiny computers that analyze and integrate information from different sources. These findings have implications for improving hearing aids, sonar devices, and speech recognition systems.
