Ellen has finished her time here last week, and Josh, Vanetta, Joe, and Megan have all been getting ready to head off for an annual conference in Australia at the end of this week. I helped Josh work on his presentation and slideshow that he'll be presenting next week, and later shadowed Carrie as she showed me how to do DNA extraction. We started with mRNA, made cDNA, then converted back to RNA and then DNA once again. Tuesday, we ran the PCR for this, and irradiated the mice for Wednesday's bone marrow transplant.
Journal Club was led by Josh this week, and I spent some time really trying to understand the article before the meeting. Surprisingly, I found that it was pretty straightforward, and that I really was understanding most of the data just reading it through myself. The article dealt with an immunostimulatory T cell Ig mucin (Tim)-1 specific antibody that deprograms Tregs. T-regs are a type of CD4+ helper T-cells that are resonsible for immunosuppression and anti-inflammation, which make them key players in tolerance studies as they do their best to prevent a graft-vs-host immune response. With the T-regs "deprogrammed" - or not completely functional in the presence of this 3B3 anti-Tim-1 mAb, transplant tolerance is not possible. I ended up presenting a couple of the figures, which was an initially uncomfortable but altogether rewarding experience. It's really hard to sit in front of PhDs and MDs and attempt explain a scientific figure, but I'm glad I did. Explaining the figures to others also helped me realize exactly how much of the material I had understood.
Reflecting back on everything, I can't even imagine how everything was at the lab eight weeks ago. Time has definitely moved fast. Science, and research in particular, has tremendous potential in so many different areas of study. To think that in a few years, we may have gotten much closer to finding different alternatives and better success rates for organ transplants, or cured autoimmune diseases, is an amazing thing. Although research will inevitably lead to a lot of failure, it also leads to great success, and with more breakthroughs that will follow in time to come, we are sure to progress in treatment and care of humans. Everything here starts in the mouse, but success at the smaller animal level is what leads to clinical trials and success in people. I will really miss coming here and learning something new every single day. I've realized that what I love most is talking about the science behind the lab work, and how that thought process can generate new hypotheses that we can look forward to testing and growing on. It was a wonderful experience that I'm very grateful for, and I can only hope to come back to later on. Thank you!
