Transient receptor potential canonical (TRPC) proteins constitute a group of receptor-operated calcium-permeable nonselective cationic membrane channels of the TRP superfamily. They are largely expressed in the hippocampus and are able to modulate neuronal functions. Accordingly, they have been involved in different hippocampal functions such as learning processes and different types of memories, as well as hippocampal dysfunctions such as seizures. This review covers the mechanisms of activation of these channels, how these channels can modulate neuronal excitability, in particular the after-burst hyperpolarization, and in the persistent activity, how they control synaptic plasticity including pre- and postsynaptic processes and how they can interfere with cell survival and neurogenesis.

Brain ischemia is a major global cause of disability, frequently leading to psychoneurological issues. This study investigates the effects of 4-aminopyridine (4-AP) on anxiety, cognitive impairment, and potential underlying mechanisms in a mouse model of medial prefrontal cortex (mPFC) ischemia. Mice with mPFC ischemia were treated with normal saline (NS) or different doses of 4-AP (250, 500, and 1000 µg/kg) for 14 consecutive days.

Background: The protective function of the tetrandrine (TET)-mediated transient receptor potential vanilloid 2 (TRPV2) channel in myocardial ischemia/reperfusion injury (MI/RI) has been established in numerous investigations. The objective of the current study was to explain how TRPV2 further modulates downstream factors to influence the progression of MI/RI.
Methods: To this end, an MI/RI model in rats and a hypoxia-reoxygenation (H/R) cell model in H9c2 cells were constructed.

G protein-coupled receptors (GPCRs) engage multiple transducers to regulate distinct physiological processes. These transducers include various G proteins subtypes, GPCR kinases (GRKs), and β-arrestins. In addition to promoting receptor desensitization, β-arrestins serve as scaffolds for signaling via non-G protein pathways.

The thermosensitive transient receptor potential (Thermo-TRP) channel proteins comprise TRPA1, TRPV1-V4, and TRPM8. TRP channels are mainly situated on cellular surfaces and react to a range of external factors, including heat, cold, acidity, osmotic pressure, chemical signals, and flavors, as well as intracellular signals such as Ca, Na, and cytokines. The thermo-TRP channels are associated with many physiological signal pathways, with their distinct molecular structure making them promising drug targets for respiratory diseases.
