Chemosensors in the Nose: Guardians of the Airways

Physiology, 2013
The G-protein-coupled receptor molecules and downstream effectors that are used by taste buds to detect sweet, bitter, and savory tastes are also utilized by chemoresponsive cells of the airways to detect irritants. Here, we describe the different cell types in the airways that utilize taste-receptor signaling to trigger protective epithelial and ...

Drafting the calmodulation playbook: Emerging structural insights into transient receptor potential channel regulation by calmodulin

The Journal of Physiology, EarlyView.
Abstract figure legend Calmodulin (CaM) is a ubiquitous calcium (Ca2+) sensor that translates intracellular Ca2+ signals into modulation of hundreds of effector proteins including ion channels. CaM is increasingly recognized as a key regulator of the transient receptor potential (TRP) channel family, yet the underlying ‘calmodulation playbook’ is only ...

Probing the Architecture of Organic Heterojunctions Based on Zn(Salen)‐Type/Lu(Bis‐phthalocyanine) Complexes and Their Potential Application as Gas Sensors

Advanced Materials Interfaces, Volume 13, Issue 19, 6 October 2026.
Planar bilayer heterojunctions are fabricated from two molecular materials and compared to solution‐processed bulk heterojunctions. Raman spectroscopy and conductive AFM studies reveal the formation of conductive pillar‐like structures within a poorly conductive matrix.
