On November 5, Patrick Brennan received an Honor Alumni Award for lifetime achievement from the institution where he received his PhD degree, Trinity College, Dublin University. He was one of only 4 recipients of the award. In the typical Trinity style (it was founded at the same time as Oxford and Cambridge Universities by Queen Elizabeth I) the award was bestowed with a lot of pomp and circumstance (which Pat's family attempted to fracture by the attendance of his 4-year-old and 2-month-old grandchildren). In the end, the kids behaved very well and looked splendid in their black tie and velvet cocktail dress.
On October 22-23, ~60 hearty microbiologists congregated on the campus of the University of Wyoming in Laramie for the Fall meeting of the Rocky Mountain Branch of the American Society for Microbiology. Attendees heard outstanding plenary presentations from Drs. Naomi Ward and Rachel Watson, 18 talks from submitted abstracts and mulled over a slew of interesting posters. Several awards were doled out for student and postdoc presentations, but alas MIP was shut out of the bling for the first time in recent memory (foretelling the performance of the CSU football team in the Bronze Boot border war game I guess). No worries though – another opportunity for MIP undergrads, grad students and postdocs to present their research is just around the corner. The Spring meeting of the RM-ASM will take place April 1-2, 2011 on the CU-Boulder campus.

MIP Researchers Receive Funds to Support Undergrad Research Opportunities
12 MIP faculty were awarded $500 allocations from the CVMBS College Council to support undergraduate research projects next semester. Demonstrating the strong commitment to undergraduate research in MIP, two-thirds of the funds awarded by the Council at its Nov. 16th meeting went to applications from our department. Congratulations to Drs. Chatterjee, Eckstein, Gonzalez-Juarrero, Inamine, Izzo, Klein, Olver, Ordway, Quackenbush, Schenkel, C. Wilusz and J. Wilusz for submitting successful applications. Looks like we should expect a strong contingent of micro majors presenting their research at the CURC once again this April!
Michael Wiseman, DVM, presented his MS Defense entitled, "Flow cytometry in the diagnosis and prognosis of canine lymphoma and leukemia", on Tues, Nov 2. Dr. Paul Avery is his advisor

BluePort: a platform to study the eosinophilic response of mice to the bite of a vector of Leishmania parasites, Lutzomyia longipalpis sand flies.

PLoS One. 2010 Oct 27;5(10):e13546
Anyone who has spent long hours in the cold room doing column chromatography knows how it can really get under your skin at times. Perhaps this was the inspiration for Santiago et al to take cibracron blue agarose beads - a common column matrix for separating albumin from blood samples – and literally injecting the beads into the dermis of mice. Interestingly (and pardon the upcoming bad pun), the mice didn't ‘dye’, but rather the beads remained in place for months, inducing a highly vascularized, macrophage-rich tissue compartment around a collagen-rich extracellular matrix. The beads also produced an easy to recognize blue nodule in the skin under the fur of our four-legged little lab friends.
While turning regions of mouse skin Duke blue is pretty cool in and of itself given that we're now into college basketball season, the five MIP amigos in the author line set out to do a few other neat things with these nodules. They used this region to assess the localized immune reaction to the saliva in sandfly bites, an important mediator of Leishmania transmission. In a series of well-documented experiments, they demonstrated that a switch in the inflammatory response from the typical invasion of neutrophil cells towards a more eosinophil-centric response occurred faster in the cibacron blue nodular areas. This switch to the recruitment of pink-staining white blood cells is strongly associated with acquired immunity to sandfly saliva delivery of Leishmania, implying that the beads could help with vaccine development. The other interesting aspect of this study is that the authors demonstrate that the cibacron dye beads may be setting up a type of ectopic lymph node. If this is indeed true, it may have far-reaching implications in terms of antigen delivery for vaccine development and a novel way to study immunological reactions to pathogens delivered through the skin.
So why did we chose this PLoS One-of-a-kind article for our coveted MIPublication of the month? First, it represents an interesting, and as far as we can tell fairly novel technique for studying and inducing immune reactions to antigens injected subcutaneously. Second, with three different MIP labs involved, the paper is a great example of the outstanding synergy that we've grown accustomed to seeing among departmental research teams. Finally, it gives us an opportunity to reinforce the fact that MIP parasitology research is not just a fad anymore, it's Leish-mania!

MIP is adopting 3 families this year through the Salvation Army – each family has 4 kids. Like last year, there will be Christmas trees with tags listing suggestions for gifts and $ amounts located in the departmental offices at Pathology, Microbiology and out at the foothills. We will take only new items as this is the only time many of these kids receive anything brand new. We will also accept Walmart Gift Cards, cash donations and wrapping supplies.
Gifts/donations must be returned to the Department Offices or to Carol Wilusz by December 14 so they can be delivered to the families in time for the holidays.
Once again, the Annual Thanksgiving Potluck was a well-attended gathering of the MIP Family filled with delicious foods and friendly conversation. A BIG THANKS to John Spencer, Carol Blair, and Susan Deines for providing Turkey's and to RoxAnn Karkhoff-Schweizer for providing the Ham. Also, a HUGE THANKS to Karen Hofmaier, Corrine Lindstadt, and Heidi Runge for all their hard work at coordinating and setting-up the event.

MIP 700 - Topics Course
This class will examine the mechanisms and pathogenesis of autoimmune diseases. The first 2 – 3 weeks of the semester will be devoted to understanding the mechanisms protecting us from autoimmune disease, including central and peripheral T and B cell tolerance, and regulatory T cell biology. For the remainder of the semester we will examine individual autoimmune diseases with an emphasis on how they develop despite tolerance mechanisms, and how autoimmune results in clinical disease.
On October 29, various members of the MIP Family enjoyed Halloween by wearing costumes, ‘putting for treats’ in Jim Frantz' office, or eating some of Susan Deines' yummy spider cupcakes. The MIP Office staff also participated in a Chili contest where Ida Tieman won the "Hottest Chili", Jeanette Fritzler won the "Best Chili", and Cathy Griffin won "Best Costume". In addition, witnesses have reported that Dr. Hoover was seen consulting with the Great Pumpkin....
Be sure to check out all the great costumes at our MIP 2010 Halloween Photo Gallery.
