Professor Jon Lane
My lab work studies autophagy and other cellular responses to stress. We use transformed human cells and human iPSC-derived neurons and glia to understand how autophagy shapes neuronal responses to stress Parkinson's.

Professor of Cell BiologySchool of Biochemistry
I graduated with a BSc in Biology from Southampton University, and then studies for a PhD in Exeter on the cell cycle regulation of microtubule dynamics. This led to PostDoctoral work in Manchester on developmental microtubule motor control, and organelle disruption and altered protein trafficking in apoptosis. A Wellcome Trust Career Development Fellowship brought me to Bristol, where I have continued researching cellular responses to stress, with a focus on membrane trafficking and dynamics.
Over recent years, my group has concentrated on the process of autophagy - a crucial cellular stress response pathway that plays important roles in a variety of human diseases. We study how autophagy influences neuronal resilience in Parkinson's, using human induced pluripotent stem cells (hiPSCs) from which we grow human neurons and glia in the lab.
My lab is interested in autophagy - the regulated recycling of cytoplasmic material through delivery and degradation in the lysosome.

Autophagy (macroautophagy) is characterised by the formation of double membrane-bound organelles that sequester regions of cytoplasm including misfolded protein aggregates and organelles.The autophagosome membrane is decorated with a protein known as Atg8 (commonly known as LC3), which plays roles in autophagosome assembly and cargo selection.
We use live-cell imaging as well as fixed cell microscopy (including electron microscopy) to explore how and where autophagosomes are assembled. Through the application of cell-lines expressing GFP-tagged autophagy proteins (such as Atg5; Atg14; Atg16L; DFCP1), we can determine how the sequential recruitment of autophagy factors influences autophagosome assembly.
In our studies we used various human and mouse cell culture lines, primary human erythroid precursors and induced pluripotent stem cells from human patients. The latter we differentiate into specific neural lineages to understand how autophagy is regulated in neurons for research into the causes of neurodegenerative diseases (Parkinson’s disease; Alzheimer’s disease).

I teach on all years of the Biochemistry BSc/MSci programmes, covering mitosis and the cell cycle, apoptosis, and autophagy in health and disease. I also contribute to teachng on MSc and PhD programmes, including through lectures, Journal clubs, tutorials, and workshops.
