Feeling Every Bit of Winter – Distributed Temperature Sensitivity in Vernalization

open access: yesFrontiers in Plant Science, 2021
Temperature intrinsically influences all aspects of biochemical and biophysical processes. Organisms have therefore evolved strategies to buffer themselves against thermal perturbations.

Hydrogen‐Bonded Cholesteric Liquid Crystals—A Modular Approach Toward Responsive Photonic Materials

open access: yesAdvanced Photonics Research, 2022
A supramolecular approach for photonic materials based on hydrogen‐bonded cholesteric liquid crystals is presented. The modular toolbox of low‐molecular‐weight hydrogen‐bond donors and acceptors provides a simple route toward liquid crystalline materials

Engineering vanilloid-sensitivity into the rat TRPV2 channel

open access: yeseLife, 2016
The TRPV1 channel is a detector of noxious stimuli, including heat, acidosis, vanilloid compounds and lipids. The gating mechanisms of the related TRPV2 channel are poorly understood because selective high affinity ligands are not available, and the ...

Structural insights into the mechanism of activation of the TRPV1 channel by a membrane-bound tarantula toxin

open access: yeseLife, 2016
Venom toxins are invaluable tools for exploring the structure and mechanisms of ion channels. Here, we solve the structure of double-knot toxin (DkTx), a tarantula toxin that activates the heat-activated TRPV1 channel. We also provide improved structures

What Temperature of Coffee Exceeds the Pain Threshold? Pilot Study of a Sensory Analysis Method as Basis for Cancer Risk Assessment

open access: yesFoods, 2018
The International Agency for Research on Cancer (IARC) evaluates “very hot (>65 °C) beverages” as probably carcinogenic to humans. However, there is a lack of research regarding what temperatures consumers actually perceive as &ldquo ...

RNA thermosensors facilitate Streptococcus pneumoniae and Haemophilus influenzae immune evasion.

open access: yesPLoS Pathogens, 2021
Bacterial meningitis is a major cause of death and disability in children worldwide. Two human restricted respiratory pathogens, Streptococcus pneumoniae and Haemophilus influenzae, are the major causative agents of bacterial meningitis, attributing to ...

Injury Threshold of Oral Contact with Hot Foods and Method for Its Sensory Evaluation

open access: yesSafety, 2018
Epidemiological studies indicate an increased risk of esophageal cancer from the consumption of very hot foods and beverages. The contact time and the contact temperature are decisive for the risk of injury.

Transmembrane Prolines Mediate Signal Sensing and Decoding in Bacillus subtilis DesK Histidine Kinase

open access: yesmBio, 2019
Environmental awareness is an essential attribute of all organisms. The homeoviscous adaptation system of Bacillus subtilis provides a powerful experimental model for the investigation of stimulus detection and signaling mechanisms at the molecular level.

Structural basis for intrinsic thermosensing by the master virulence regulator RovA of Yersinia [PDF]

open access: yes, 2012
Pathogens often rely on thermosensing to adjust virulence gene expression. In yersiniae, important virulence-associated traits are under the control of the master regulator RovA, which uses a built-in thermosensor to control its activity.
