Gene mutations and gene copy number variants are associated with autism spectrum disorders (ASDs). Affected gene products are often part of signaling networks implicated in synapse formation and/or function leading to alterations in the excitation/inhibition (E/I) balance. Although the network of parvalbumin (PV)-expressing interneurons has gained particular attention in ASD, little is known on...

Transient receptor potential vanilloid subtype 1 (TRPV1) receptor is a pain-sensing, ligand-gated, non-selective cation channel expressed in peripheral sensory neurons. Prolonged activation of TRPV1 by capsaicin leads to cell swelling and formation of membrane blebs in rat dorsal root ganglion (DRG) neurons. Similar results were obtained in NIH3T3 fibroblast cells stably expressing TRPV1. Here,...

Menthol is a naturally occurring monoterpene alcohol possessing remarkable biological properties including antipruritic, analgesic, antiseptic, anti-inflammatory and cooling effects. Here, we examined the menthol-evoked Ca2+ signals in breast and prostate cancer cell lines. The effect of menthol (50–500µM) was predicted to be mediated by the transient receptor potential ion channel...

Aims: Parenchymal microcalcification in the brain coincides with neurodegenerative diseases, but is also frequently found in neurologically normal individuals. The origin and role of this process are still under debate. Parvalbumin (PV) is a protein acting as a Ca2+ buffer and Ca2+ shuttle towards intracellular Ca2+ sinks, like mitochondria and the endoplasmic reticulum. Constitutively, it is...

Malignant mesothelioma (MM) is an aggressive asbestos-linked neoplasm, characterized by dysregulation of signaling pathways. Due to intrinsic or acquired chemoresistance, MM treatment options remain limited. Calretinin is a Ca2+-binding protein expressed during MM tumorigenesis that activates the FAK signaling pathway, promoting invasion and epithelial-to-mesenchymal transition. Constitutive...

It is generally thought that transmitter release at mammalian central synapses is triggered by Ca²⁺ microdomains, implying loose coupling between presynaptic Ca²⁺ channels and Ca²⁺ sensors of exocytosis. Here we show that Ca²⁺ channel subunit immunoreactivity is highly concentrated in the active zone of GABAergic presynaptic terminals of putative parvalbumin-containing basket cells in...

Following nerve injury in neonatal rats, a large proportion of motoneurons die, possibly as a consequence of an increase in vulnerability to the excitotoxic effects of glutamate. Calcium-dependent glutamate excitotoxicity is thought to play a significant role not only in injury-induced motoneuron death, but also in motoneuron degeneration in diseases such as amyotrophic lateral sclerosis (ALS)....

The Ca2+-binding protein parvalbumin (PV) and mitochondria play important roles in Ca2+ signaling, buffering and sequestration. Antagonistic regulation of PV and mitochondrial volume is observed in in vitro and in vivo model systems. Changes in mitochondrial morphology, mitochondrial volume and dynamics (fusion, fission, mitophagy) resulting from modulation of PV were investigated in MDCK...
