Mechanistic insights into allosteric regulation of the A2A adenosine G protein-coupled receptor by physiological cations. [PDF]

, 2018
Cations play key roles in regulating G-protein-coupled receptors (GPCRs), although their mechanisms are poorly understood. Here, 19F NMR is used to delineate the effects of cations on functional states of the adenosine A2A GPCR.

Differential sensitivity of antinociceptive tests to opioid agonists and partial agonists [PDF]

British Journal of Pharmacology, 1988
The antinociceptive activity of a range of opioid agonists and agonist‐antagonist analgesics was determined in mice by use of the 55°C hot plate and abdominal constriction assays. Opioid agonists were approximately 10 times more effective in the abdominal constriction assay. The agonist‐antagonists produced analgesia only in the abdominal constriction

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

Advanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

Tetrahydrocannabivarin (THCV) Dose Dependently Blocks or Substitutes for Tetrahydrocannabinol (THC) in a Drug Discrimination Task in Rats

Biomolecules
Delta-9-Tetrahydrocannabivarin (THCV), a naturally occurring cannabinoid and structural analog of THC, exhibits a dual pharmacological profile as a CB1 receptor agonist/antagonist and a partial CB2 agonist.

Controlled Movement of Soft Actuators using Multi‐Responsive Microgel Arrays and Microcirculatory Systems

Advanced Functional Materials, EarlyView.
Microscale hydrogels (microgels) feature improved mass transport characteristics supportive of fast actuation and chemical tunability amenable to programmed stimuli response. A unique soft actuator architecture is realized by encapsulating microgels in soft microcirculatory systems which enable the convenient delivery of liquid stimuli for powering and

A fluorophore attached to nicotinic acetylcholine receptor beta M2 detects productive binding of agonist to the alpha delta site [PDF]

, 2004
To study conformational transitions at the muscle nicotinic acetylcholine (ACh) receptor (nAChR), a rhodamine fluorophore was tethered to a Cys side chain introduced at the beta-19' position in the M2 region of the nAChR expressed in Xenopus oocytes ...

The melanocortin receptors and their accessory proteins. [PDF]

, 2013
The five melanocortin receptors (MCRs) named MC1R-MC5R have diverse physiological roles encompassing pigmentation, steroidogenesis, energy homeostasis and feeding behavior as well as exocrine function.

MagPiezo: A Magnetogenetic Platform for Remote Activation of Endogenous Piezo1 Channels in Endothelial Cells

Advanced Functional Materials, EarlyView.
MagPiezo enables wireless activation of endogenous Piezo1 channels without genetic modification using 19 nm magnetic nanoparticles and low‐intensity magnetic fields. It generates torque forces at the piconewton scale to trigger mechanotransduction in endothelial cells, standing as a novel platform to interrogate and manipulate Piezo1 activity in vitro.

Distinct immune signatures in directly treated and distant tumors result from TLR adjuvants and focal ablation. [PDF]

, 2018
Both adjuvants and focal ablation can alter the local innate immune system and trigger a highly effective systemic response. Our goal is to determine the impact of these treatments on directly treated and distant disease and the mechanisms for the ...
