PhDIt is clear that the voltage-‐gated proton channel HVCN1 plays an essential role in
a range of cell types, in particular immune cells. Previous published work
has confirmed the existence of proton
channels in both murine and human macrophages. However, the role of HVCN1 in
macrophages has not been investigated.
Given that the current literature on
voltage-‐gated proton channels in immune
cells has found HVCN1 to be involved in
several cellular processes (such as the
respiratory burst and signalling events)
it is important to establish its
functional role in macrophages, which are
a crucial constituent of the immune system. The aim of my thesis was to investigate the function of voltage-‐gated proton channels in macrophages with the use of mice with a disrupting mutation within the Hvcn1 gene, which results in HVCN1 loss. In particular, I wanted to address how Hvcn1-‐/-‐ macrophages responded to LPS activation. I hypothesised that HVCN1 regulates the respiratory burst of macrophages and
that it potentially modulates mitochondrial ROS production, and in doing so, may affect several functional aspects of macrophage biology
