Kinsenoside Targets IDH1 to Restore Microglial Immune‐Metabolic Homeostasis for Alzheimer's Disease Therapy

open access: yesAdvanced Science, EarlyView.
Dysregulated TCA cycle contributes to Alzheimer's disease (AD) pathogenesis. Here, we show that microglial isocitrate dehydrogenase 1 (IDH1) is a critical driver. Elevated IDH1 disrupts citrate metabolism and mitochondrial function, exacerbating AD pathology.

Interactive impacts of social deprivation and intranasal oxytocin administration on oxytocin receptor density in prairie vole brains

open access: yesFrontiers in Behavioral Neuroscience
IntroductionEarly-life social experiences have a profound impact on the development of the brain and behavior. Previous work has shown that prairie voles (Microtus ochrogaster) raised in a socially limited environment (raised by a single mother and ...

Repeated Clozapine Increases the Level of Serotonin 5-HT1AR Heterodimerization with 5-HT2A or Dopamine D2 Receptors in the Mouse Cortex

open access: yesFrontiers in Molecular Neuroscience, 2018
G-protein–coupled receptor (GPCR) heterodimers are new targets for the treatment of schizophrenia. Dopamine D2 receptors and serotonin 5-HT1A and 5-HT2A receptors play an important role in neurotransmission and have been implicated in many human ...

Fosl2 Regulates FSH‐Dependent Follicle Maturation Through Feedback Amplification of FSH/FSHR Signaling

open access: yesAdvanced Science, EarlyView.
This study identifies a FOSL2‐driven positive feedback loop that amplifies FSH/FSHR signaling. During FSH‐dependent follicle maturation, FSH induces Fosl2 expression via the cAMP‐PKA‐CREB cascade. FOSL2 in turn binds the promoters of Fshr and estrogen‐biosynthesis genes to enhance their transcription, thereby increasing Fshr mRNA level and amplifying ...

Decoding the Mechanism of Action of a Parasite TGFβ Antagonist Inspires the Creation of Cell‐Type‐Specific TGFβ Modulators

open access: yesAdvanced Science, EarlyView.
The mammalian TGFβ interacts with ubiquitously expressed TGFBR1 and TGFBR2, and current TGFβ‐targeting agents are non‐cell‐selective. The cooperative interaction of the modular parasite TGFβ antagonist with multiple host (co‐)receptors empowers the design of TGM chimeras and bispecific antibodies that activate or inhibit TGFβ signaling in a cell ...

11C-Autoradiographs to Image Phloem Loading

open access: yesFrontiers in Forests and Global Change, 2019
Generally, tree species load photoassimilates passively into the phloem, while herbaceous species load actively. These phloem loading strategies have implications for phloem sugar concentration and growth potential.

Prenatal betamethasone–postnatal N‐methyl‐D‐aspartic acid model of spasms: Update on mechanisms and treatments

open access: yesEpilepsia Open, EarlyView.
Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...

Mitochondrial DNA synthesis studied autoradiographically in various cell types in vivo

open access: yesBrazilian Journal of Medical and Biological Research, 1998
It is generally accepted that mitochondria are able to proliferate even in postmitotic cells due to their natural turnover and also to satisfy increased cell energy requirements.

Epilepsy surgery: From bench to the clinics

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Recent advances in epilepsy surgery in patients with intractable epilepsy make it possible to study the mechanism of epilepsy in human brains. However, the true extent and propagation of each epileptogenic area from the epileptogenic focus in each patient is still difficult to perform “epilepsy cure” by surgery.

Ultrastructural, autoradiographic and electrophoretic examinations of Chara tomentosa spermiogenesis

open access: yesActa Societatis Botanicorum Poloniae, 2014
Ultrastructure of a spermatid nucleus changes many times during spermiogenesis. Condensed chromatin forms irregular clusters during phases I-II, a continuous ring adjacent to a nuclear envelope during phases III-V and a network occupying the whole ...
