Agonist-directed desensitization of the β2-adrenergic receptor. [PDF]
The β(2)-adrenergic receptor (β(2)AR) agonists with reduced tachyphylaxis may offer new therapeutic agents with improved tolerance profile. However, receptor desensitization assays are often inferred at the single signaling molecule level, thus ligand ...

To clarify the determinants of agonist efficacy in pentameric ligand-gated ion channels, we examined a new compound, aminomethanesulfonic acid (AMS), a molecule intermediate in structure between glycine and taurine.

Evaluation of partial ?-adrenoceptor agonist activity [PDF]
A partial β‐adrenoceptor (β‐AR) agonist will exhibit opposite agonist and antagonist activity depending on the prevailing degree of adrenergic tone or the presence of a β‐AR agonist with higher intrinsic activity. In vivo partial β‐AR agonist activity will be evident at rest with low endogenous adrenergic tone, as for example with chronotropicity (β1 ...

Hematopoietic (stem) cells—The elixir of life?
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

BU10038 as a safe opioid analgesic with fewer side-effects after systemic and intrathecal administration in primates [PDF]
© 2019 British Journal of Anaesthesia. Published by Elsevier Ltd. All rights reserved.Background: The marked increase in mis-use of prescription opioids has greatly affected our society. One potential solution is to develop improved analgesics which have

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization
CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

The NMDA agonist D-cycloserine facilitates fear memory consolidation in humans [PDF]
Animal research suggests that the consolidation of fear and extinction memories depends on N-methyl D-aspartate (NMDA)- type glutamate receptors.

Agonists and Partial Agonists of Rhodopsin: Retinals with Ring Modifications [PDF]
Activation of the visual pigment rhodopsin is initiated by isomerization of its retinal chromophore to the all-trans geometry, which drives the conformation of the protein to the active state. We have examined by FTIR spectroscopy the impact of a series of modifications at the ring of retinal on the activation process and on molecular interactions ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in
