Description | At the onset of the project we have made a good progress in identifying interactions between the ANO1-like protein TMC7 and TRPV1 in mammalian sensory neurons. However, after pandemics started, no further academic exchange was possible. The collaboration that started with the onset of this award has resulted in investigation of the molecular composition of the Kv4 potassium channel complex. This work has been published in the FASEB Journal. Additionally, we characterised the role of Kv7.4 potassium channels in vascular inflammation and remodeling. These findings are now published in Free Radical Biology and Medicine. |
Exploitation Route | The visiting scheme worked excellently before the lockdown and formed a foundation to further collaborations. However, currently the short visit research exchange with China is not possible. |

Title | A correlative super-resolution protocol to visualise structural underpinnings of fast second-messenger signalling in primary cell types |
Description | A correlative imaging protocol which allows the ubiquitous intracellular second messenger, calcium (Ca2+), to be directly visualised against nanoscale patterns of the Ca2+ channels in primary cells. This is achieved by combining total internal reflection fluorescence (TIRF) imaging of the elementary Ca2+ signals, with the subsequent DNA-PAINT super-resolution imaging of the Ca2+ channels. |
Type Of Material | Technology assay or reagent |
Year Produced | 2020 |
Provided To Others? | Yes |
Impact | Most super-resolution microscopy methods require fixed cells/tissue. Here we developed a correlative approach in which live signaling events recorded from the living cells can be matched to the nanoscale structural information obtained with super-resolution imaging. This will further the scope of super-resolution imaging. |
Title | All-optical monitoring of chloride channel activity in living cells |
Description | We developed a triple-wavelength fluorescent imaging approach to simultaneously perform halide-sensitive EYFP quenching (to measure Cl- channel activity) and ratiometric fura-2 Ca2+ imaging. The method can be used as a higher-throughput alternative to patch-clamp for studying Ca2+-activated Cl- channels. |
