Dose-Dependent Regulation on Prefrontal Neuronal Working Memory by Dopamine D1 Agonists: Evidence of Receptor Functional Selectivity-Related Mechanisms

Frontiers in Neuroscience, 2022
Low doses of dopamine D1 agonists improve working memory-related behavior, but high doses eliminate the improvement, thus yielding an ‘inverted-U’ dose-response curve.

Location bias contributes to functionally selective responses of biased CXCR3 agonists

Nature Communications, 2022
Subcellular signaling is critical to generating cellular responses that modulate inflammatory pathways at the chemokine receptor CXCR3. Eiger et al.

The negation bias: When negations signal stereotypic expectancies. [PDF]

Journal of Personality and Social Psychology, 2010
Research on linguistic biases shows that stereotypic expectancies are implicitly reflected in language and are thereby subtly communicated to message recipients. We examined whether these findings extend to the use of negations (e.g., not smart instead of stupid). We hypothesized that people use more negations in descriptions of stereotype-inconsistent

Kinetics of cytokine receptor trafficking determine signaling and functional selectivity

eLife, 2019
Cytokines activate signaling via assembly of cell surface receptors, but it is unclear whether modulation of cytokine-receptor binding parameters can modify biological outcomes.

Bias Detection via Signaling

Advances in Neural Information Processing Systems 37
We introduce and study the problem of detecting whether an agent is updating their prior beliefs given new evidence in an optimal way that is Bayesian, or whether they are biased towards their own prior. In our model, biased agents form posterior beliefs that are a convex combination of their prior and the Bayesian posterior, where the more biased an ...

High-resolution deep mutational scanning of the melanocortin-4 receptor enables target characterization for drug discovery

eLife
Deep Mutational Scanning (DMS) is an emerging method to systematically test the functional consequences of thousands of sequence changes to a protein target in a single experiment.

BIAS IN SELF‐EVALUATION: SIGNAL PROBABILITY EFFECTS [PDF]

Journal of the Experimental Analysis of Behavior, 1994
Two experiments examined apparent signal probability effects in simple verbal self‐reports. After each trial of a delayed matching‐to‐sample task, young adults pressed either a “yes” or a “no” button to answer a computer‐presented query about whether the most recent choice met a point contingency requiring both speed and accuracy. A successful matching‐

The Differentiation Balance of Bone Marrow Mesenchymal Stem Cells Is Crucial to Hematopoiesis. [PDF]

, 2018
Bone marrow mesenchymal stem cells (BMSCs), the important component and regulator of bone marrow microenvironment, give rise to hematopoietic-supporting stromal cells and form hematopoietic niches for hematopoietic stem cells (HSCs).

Escherichia coli Remodels the Chemotaxis Pathway for Swarming

mBio, 2019
Many flagellated bacteria “swarm” over a solid surface as a dense consortium. In different bacteria, swarming is facilitated by several alterations such as those corresponding to increased flagellum numbers, special stator proteins, or secreted ...
