Molecular determinants of signal transduction in tropomyosin receptor kinases
FEBS Open Bio, EarlyView.Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Involvement of Protein Kinase C and Protein Kinase A in the Enhancement of L-type Calcium Current by GABA\u3csub\u3eB\u3c/sub\u3e Receptor Activation in Neonatal Hippocampus [PDF]
, 2011 In the early neonatal period activation of GABAB receptors attenuates calcium current through N-type calcium channels while enhancing current through L-type calcium channels in rat hippocampal neurons.

ER localized bestrophin1 activates Ca2+ dependent ion channels TMEM16A and SK4 [PDF]
, 2009 Bestrophins form Ca2+ activated Cl- channels and regulate intercellular Ca2+ signaling1. We demonstrate that bestrophin 1 is localized in the endoplasmic reticulum (ER), where it physically interacts with stromal interacting molecule 1 (Stim1), the ER ...

Dual Regulation of Voltage-Sensitive Ion Channels by PIP2
Frontiers in Pharmacology, 2012 Over the past 16 years, there has been an impressive number of ion channels shown to be sensitive to the major phosphoinositide in the plasma membrane, phosphatidilinositol 4,5-bisphosphate (PIP2). Among them are voltage-gated channels, which are crucial

FEBS Open Bio, EarlyView.Light activation of the photoswitchable cannabinoid ligand azo‐HU308 triggers Ca2+ influx in pancreatic β‐cells through TRPC channels, independent of CB2 cannabinoid receptors. This reveals a non‐GPCR pathway for cannabinoid modulation of β‐cell Ca2+ dynamics and establishes azo‐HU308 as an optical tool to study cannabinoid signaling through TRP ...

TMC4 localizes to multiple taste cell types in the mouse taste papillae
FEBS Open Bio, EarlyView.Transmembrane channel‐like 4 (TMC4), a voltage‐dependent chloride channel, plays a critical role in amiloride‐insensitive salty taste transduction. TMC4 is broadly expressed in all mature taste cell types, suggesting a possible involvement of multiple cell types in this pathway.

Age‐Related Changes in Myeloid Cells and Their Impact on Subcutaneous Melanoma Growth in Mice
Aging and Cancer, EarlyView.Our findings reveal that age‐related changes in subcutaneous melanoma growth and immunotherapy response are context‐dependent. In models where tumor growth and treatment resistance increase with age, this effect is partly driven by enhanced immunosuppression from myeloperoxidase‐active Gr‐1⁺ myeloid cells.
