Inside our cells there is a humungous number of proteins which all interact in very complicated pathways to direct the cell to do things – like release chemical messages (cytokines) or divide into more cells (proliferate).
No one is very clear on how some of these proteins work, what other proteins they interact with and how some of them are needed for important cell functions.  What happens if we don’t have these proteins in the cell?  or we have a broken version of a protein that can’t do its job?  what makes very similar proteins different?  if one isn’t there can another one step in and take over?  These are the sorts of questions I am trying to answer about a family of proteins called the Class 1A phosphoinositide-3-kinases (catchy huh?!)…at least one of them appears to be very important for the functioning of white blood cells in our bodies.

This picture shows some of these proteins inside a cell and how they talk to each other – check it out – its soooo confusing!!!

White blood cells are what fight for us to stop us getting sick – so its pretty important to know whats going on inside them to make them work!  This picture shows a type of white blood cell called a dendritic cell (in blue) “talking” to a T cell (another white blood cell – shown in yellow in the picture).  Dendritic cells travel around the body looking for bacterial invaders and when they find a bad guy they swallow him and present bits of him on their surface to T cells – this tells the T cells that there’s an invasion and they get activated and ready to fight!

So….a typical day in the life of me!  I get up (its a good start) and make myself an amazing smoothie…okay this morning it was just strawberries, bananas, milk and cranberry juice so I’m not exactly giving Innocent a run for their money!  Then I head out to catch the “Anne taxi” from the top of my street (this sounds intriguing but actually its not a taxi for people named Anne …or a taxi firm owned by Anne…its just my friend Anne – in her boyfriend’s car). 
We get to work about 8:30am (keen beans!!) and I head off to my office and then into the lab.  I usually do lab work for a big proportion of the day – extracting DNA, running gels, labelling cells, southern blotting etc. but also do some computer work and write up my lab book at my desk in the office too.
Oh, in case you’re interested, Southern blotting is a very long drawn out sort of experiment which is doing my head in…I am having a “Southern Blot-off” with the research assistant in my lab.  I am totally going to win – and keep writing so on the whiteboard mwahahahaha!!
At about 10:15am my friends Hema, Sam, Patrick and Rachel come to my office and dance around outside …this means its time for tea!  …this bit of the day is A-M-A-Z-I-N-G!!  We go down to the cafe and get tea and freshly baked scones from Luigi the cafe guy.  His name isn’t actually Luigi but he looks like Mario’s brother and acts all Italian so thats what we call him.  He is a dude and gives us free cake when no one’s watching!   
The rest of the day I carry on with lab work – stopping for lunch about 12:45pm.  If its a nice day we can eat outside because our research institute is out in the country surrounded by fields of sheep and trees so its kinda pretty!  In the afternoons we quite often have group or departmental meetings where a scientist in the lab talks about the experiments they have been doing and shows us their results.  Other days we have journal clubs where somebody explains in more detail a scientific paper that has just been published, or we have institute-wide talks on science topics that are not necessarily exactly what we work on.  Here are all the scientists in our little group (after having a picnic one day!)
Because I am doing a PhD I am expected to work pretty long hours so I generally don’t leave work till after 6pm – but some days this can be 9pm depending on how experiments are going…and what exciting after-work activities I have planned!!
