Sacré bleu! Congratulations to Dr. Christine Olver who has been awarded a Fulbright Scholarship. The Fulbright Program is the US government's flagship international exchange program designed to increase mutual understanding between the peoples of US and other countries. Fulbright Scholars are chosen for their academic merit and leadership potential. Christine and her savior-faire will be going to the Universite de Montpellier in Montpellier, France (which is situated in the southern part of the country on the Mediterranean Coast). We'll be saying au revoir to her for ~ 7 months on January 1, 2010.

Callahan New Book Signing

"Every year in the United States, more than two thousand children are born with an intersex condition or disorder of sex development. What makes someone a boy or a girl? Is it external genitalia, chromosomes, DNA, environment, or some combination of these factors? Not even doctors or scientists are entirely clear. What is clear is that sex is not an either-or proposition: not girl/boy, XX/XY, switching between two poles like an on-off switch on a radio. Rather, sex is like the bass and treble knobs on that radio."

MIP's Gerry Callahan has just published through Chicago Review Press his latest book entitled Between XX and XY: Intersexuality and the Myth of Two Sexes The book provides an absorbing analysis of what makes people male or female and why those who do not fit into society's preconceived notions about sex often face a difficult path in life. Dr. Callahan also examines our obsession with sex and sexual intercourse through the ages.

Gerry Callahan will be at the Reader's Cove Bookstore on Thursday, July 23, 6:30pm for a book reading/signing.

Localized Immunosuppressive Environment in the Foreign Body Response to Implanted Biomaterials

David Higgins, Randy Basaraba, April Hohnbaum, Eric Lee, David Grainger and Mercedes Gonzalez-Juarrero

The American Journal of Pathology 175: 161-170

Among most medical specialists, including dentists, orthopaedic surgeons and ‘nip and tuck’ physicians, the implantation of medical devices is fairly common. With the development of stem cell tissue rebuilding technologies on the horizon, this trend is very likely to increase. A key factor related to the success of medical implants is how the body responds to it. Major problems to date include the encapsulation of the implant in fibrous deposits or degradation of the implant by a variety of secreted enzymes. Thus predicting/manipulating how a patient will react to an implant is of major medical importance. In their spare time when they aren't unraveling the intricacies of how the human immune system reacts to Mycobacterium tuberculosis, an MIP research team led by Mercedes Gonzalez-Juarrero has started a foray into this area of medical research which is commonly called the ‘Foreign Body Response’.

In this study, Dave Higgins, Mercedes and the rest of the gang implanted a 4 x5 mm nylon mesh into the back of C57BL/6 mice to establish an experimentally tractable in vivo system to observe the temporal and spatial patterns of cell migration, cytokine gene expression and encapsulation responses to this mesh over a 10 week period. Their data supported three major conclusions. First, they confirmed what has been observed in numerous in vitro and in vivo studies over the years thus supporting the validity of their mouse-mesh model system. Basically there was the expected initial inflammatory response to the nylon mesh after two weeks that subsided fairly quickly thereafter. In terms of a cellular response, there was a focal distribution of macrophages and granulocytes readily observed around the mesh by 4 weeks. About 30% of these macrophages fused to form multinucleated giant cells. The second major conclusion they made was that the Foreign Body Response is primarily a macrophage response. The macrophages that accumulate around the nylon mesh appear to be the key cells in terms of producing lysozyme and cytokines (particularly IL4, IL10, IL13 and TGF-B. Dendritic cells don't appear to be recruited and there was no data to support a role for the handful of lymphocytes in the area in cytokine production. The third and final major conclusion of the study is that the cytokines appear to be acting in combinations (rather than on their own) to contribute to aspects of the foreign body response. These data provide valuable in vivo confirmation for previous work done in tissue culture model systems and extend our understanding of immune cell-implant relationships. The next key steps in the study will likely be to assess how the mice react to a range of biomaterials and understand the potential contribution of the immunosuppressive cytokines (IL-10 and TGF-B) that are produced to opportunistic infections of implants.

We picked this study for our coveted ‘highlight of the month’ for three reasons. First, it establishes what may be a valuable new in vivo model system to study a very important aspect of human medicine. Second, it nicely shows the awesome power of MIP immunologists and pathologists when they get together in a collaborative effort to tackle a research question. Finally, it begs the question as to whether or not Mercedes’ future research direction will involve ‘TB or not TB’ ...

MIP sends its collective condolences to Dwayne Hamar who lost his grandson in a tragic rodeo accident on June 28th

End of Trail Sculpture

“We won't be dancing together on the high wire
Facing the lions with you at my side anymore
We won't be breathin' the smoke and the fire
On a midway

Hanging from the trapeze
My wrists waiting for your wrists
Two daredevils high up on the wall of death
You throwin' the knife that lands inches from my heart

Moonrise, moonrise
The light that was in your eyes has gone away
Daybreak, daybreak
The thing in you that made me ache has gone to stay”

Quote of the Month

“If you enter this world knowing you are loved and you leave this world knowing the same, then everything that happens in between can be dealt with. ”

 ~ Michael Joseph Jackson 1958-2009


Ever notice that a good sized chunk of the name plate that hangs over Dr. Roxann Karkhoff-Schweizer's office has been blacked out?

A little speculation on why the black patch is up there..

  1. Due to historic tensions between England and Germany, the UK monarchy forced Roxann to give up the title "Dame" when she married Herbert
  2. The black patch is just a souvenir of Roxann's days as a pirate before she took her current position in MIP
  3. Roxann suffers from micromarginaphobia - fear that the left margin of your pages is too small
  4. It covers up “Don't mess with..”
  5. Submit your own

Look Great In

Your MIP



Looking for something to spice up your Monday nights? Why not consider getting a team together to compete in the CSU Bowling league at Chipper's Lanes. It's a handicapped league so you can bowl Obama-esque and still be competitive and have a great time. The MIP Dept already has one team in the league - so a little inter-lab, inter-office, or inter-MIP facility competition could be fun.

NIH Happenings
  • Is there Life After Challenge Grants?

    Don't be surprised if your ARRA Challenge grant wasn't funded, based on the huge number of submissions you'll have lots of company. On the bright side, you might consider trying to salvage all of the hard work that you put into the application by re-submitting it after considering the following three points:

    1. Under NIH policy, you can submit your Challenge Grant application again if you follow procedures for a new application (Check the "New" box on the face page; Do not include a progress report or introduction; Use the reviewer's feedback to improve the application but do not highlight reviewer comments in the research plan).

    2. Pick a new funding opportunity announcement (you cannot use the Challenge Grant announcement) and modify the application to meet its requirements.

    3. Revise your research plan to suit a four- to five-year award, rather than the two-year grant you originally applied for.

MIP Roadtrip

75 members of the extended MIP family will be watching from behind first base as the red hot Colorado Rockies take on the Chicago Cubs on Saturday, August 8th at 6:10PM at Coors Field in Denver. If you'll be attending the game, a few helpful hints:

  • Car Pooling: If you need a ride or are driving and have room for more bodies, please email Jeff Wilusz so that we can coordinate car pools.
  • Bring a hat/sunglasses. Home plate is due west from where we'll be sitting and there's a good chance of glare from the setting sun during the first couple of innings.
  • Backpacks (1 per person) are permitted but hard sided coolers, glass bottles and cans are not.
  • Don't forget to look for the MIP Dept name on the main centerfield scoreboard during the top of the 5th inning.
