Structure and dynamics of dynorphin peptide and its receptor [PDF]

arXiv, 2019
Dynorphin is a neuropeptide involved in pain, addiction and mood regulation. It exerts its activity by binding to the kappa opioid receptor (KOP) which belongs to the large family of G-protein coupled receptors. The dynorphin peptide was discovered in 1975, while its receptor was cloned in 1993.

Efficacy and Safety of Dupilumab in Glucocorticoid‐Dependent Severe Asthma

New England Journal of Medicine, 2018
BACKGROUND Dupilumab is a fully human anti–interleukin‐4 receptor α monoclonal antibody that blocks both interleukin‐4 and interleukin‐13 signaling. Its effectiveness in reducing oral glucocorticoid use in patients with severe asthma while maintaining ...

LncRNA‐MEG3 Regulates Muscle Mass and Metabolic Homeostasis by Facilitating SUZ12 Liquid–Liquid Phase Separation

Advanced Science, EarlyView.
This study has identified lncRNA‐MEG3 as a key regulator of muscle mass, promoting slow‐twitch muscle fibers and preventing muscle atrophy. By stabilizing the SUZ12/PRC2 complex through liquid–liquid phase separation (LLPS), lncRNA‐MEG3 influences mitochondrial function and lipid metabolism.

Oxytocin‐Mediate Modulation of Splenic Immunosuppression in Chronic Social Stress Through Neuroendocrine Pathways

Advanced Science, EarlyView.
Chronic social stress elevates oxytocin levels, leading to immunosuppression by enhancing regulatory T‐cell activity and promoting anti‐inflammatory macrophage polarization in the spleen. Blocking oxytocin signaling reverses these effects but worsens stress‐induced behavioral disorders and reduces survival rates. This highlights oxytocin's dual role in

From Receptor Balance to Rational Glucocorticoid Therapy

, 2014
Corticosteroids secreted as end product of the hypothalamic-pituitary-adrenal axis act like a double-edged sword in the brain. The hormones coordinate appraisal processes and decision making during the initial phase of a stressful experience and promote ...

Is there a role for glucocorticoid receptor beta in asthma?

Respiratory Research, 2000
Glucocorticoids (GCs) are routinely used as anti-inflammatory drugs in the treatment of asthma. They act through binding to glucocorticoid receptor α (GRα), which represses numerous genes encoding pro-inflammatory mediators.

Multiple Routes for Glutamate Receptor Trafficking: Surface Diffusion and Membrane Traffic Cooperate to Bring Receptors to Synapses [PDF]

Science's STKE (electronic resource) : signal transduction knowledge environment 327 (21/03/2006) 13, 2007
Trafficking of glutamate receptors into and out of synapses is critically involved in the plasticity of excitatory synaptic transmission. Endocytosis and exocytosis of receptors have initially been thought to account alone for this trafficking. However, membrane proteins also traffic through surface lateral diffusion in the plasma membrane. We describe

Comprehensive genetic analysis of poorly differentiated gastric cancer in young females

Annals of Gastroenterological Surgery, EarlyView.
Although the involvement of female sex hormones in the development of poorly differentiated gastric cancer in young females is controversial, our detailed analysis using RNA‐seq suggested that the female sex hormone, β‐estradiol plays a role in the development of poorly differentiated gastric cancer in young females. Abstract Aim The reasons behind the

Causal Mediation Analysis for Sparse and Irregular Longitudinal Data [PDF]

arXiv, 2020
Causal mediation analysis seeks to investigate how the treatment effect of an exposure on outcomes is mediated through intermediate variables. Although many applications involve longitudinal data, the existing methods are not directly applicable to settings where the mediator and outcome are measured on sparse and irregular time grids.
