Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

Advanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

Nicotinic Receptor Function in Schizophrenia [PDF]

Schizophrenia Bulletin, 1996
Schizophrenia can be partially characterized by deficits in sensory processing. Biochemical, molecular, and genetic studies of one such endophenotype, the P50 auditory-evoked potential gating deficit, suggest that one of the neuronal nicotinic receptors, the alpha 7 nicotinic receptor, may function in an inhibitory neuronal pathway involved in this ...

Activation of Lysosomal Retrograde Transport Triggers TPC1‐IP3R1 Ca2+ Crosstalk at Lysosome‐ER MCSs Leading to Lethal Depleting of ER Calcium

Advanced Science, EarlyView.
The flavonoid compound LW‐213 exerts its antitumor effects through a novel mechanism involving lysosomal‐ER calcium regulation. Specifically, LW‐213 binds to LIMP2, which induces perinuclear clustering of lysosomes and facilitates calcium‐mediated lysosome‐ER interactions.

Simultaneous Comparison of Nicotinic Receptor Antagonists on Three Nicotinic Acetylcholine Receptors

Journal of Pharmacy and Pharmacology, 1995
AbstractThe relative potencies of several nicotinic cholinoceptor antagonists in producing tetanic fade and reduction of striated muscle contraction were investigated in the isolated guinea-pig oesophagus as well as the guinea-pig and rat phrenic nerve-diaphragm preparations.

Minimally Invasive Chemical Biopsy Needle with Self‐Wettable Extraction Phase For In Vivo Tissue Sampling During Medical Procedures

Advanced Science, EarlyView.
A new tissue sampling device using an acupuncture needle with bio‐compatible extraction sorbents in the recessed section is developed. The coating material using self‐wettable particles doesn't require solvent activation after sterilization. This device is applied for the anti‐cancer drug concentration monitoring during the in vivo lung perfusion ...

Systemic injection of nicotinic acetylcholine receptor antagonist mecamylamine affects licking, eyelid size, and locomotor and autonomic activities but not temporal prediction in male mice

Molecular Brain, 2022
Nicotinic acetylcholine receptors are thought to be associated with a wide range of phenomena, such as movement, learning, memory, attention, and addiction. However, the causal relationship between nicotinic receptor activity and behavior remains unclear.

Sleep Deprivation Aggravates Periodontitis Through Trigeminal‐Periodontal Neuroimmune Pathway Mediated by the AChE‐ACh‐α7nAChR Axis

Advanced Science, EarlyView.
Sleep deprivation (SD) exacerbates ligature‐induced periodontitis (LIP) through the trigeminal nerve‐periodontal neuroimmune pathway mediated by the acetylcholinesterase (AChE)‐acetylcholine (ACh)‐α7 nicotinic receptor (α7nAChR) axis. While electroacupuncture (EA) alleviates the condition of LIP combined with SD by activating the α7nAChR.

Structural principles of distinct assemblies of the human α4β2 nicotinic receptor

Nature, 2018
Fast chemical communication in the nervous system is mediated by neurotransmitter-gated ion channels. The prototypical member of this class of cell surface receptors is the cation-selective nicotinic acetylcholine receptor.

Gut Metabolite Indole‐3‐Propionic Acid Regulates Macrophage Autophagy Through PPT1 Inhibiting Aging‐Related Myocardial Fibrosis

Advanced Science, EarlyView.
IPA is an intestinal tryptophan metabolite whose effects decline with decreased heart function. Supplementing IPA can alleviate the aging‐related myocardial fibrosis through PPT1. PPT1 is a key protein localized to lysosomes, and IPA can restore macrophage autophagy function by regulating PPT1 expresssions, thereby reducing aging‐related myocardial ...
