Dr. Bowdish gives a lecture for kids “Who’s got more cooties – boys or girls?”

Dr. Bowdish explains what cooties are, how the microbes that live on and in us can be friends and foes and describes how differences in infections and health between boys and girls, men and women are sometimes due to biology and sometimes due to behaviour.

To see Dr. Bowdish put on a macrophage cape and teach the school kids the difference between a commensal, a pathobiont and a pathogen by dressing up their teachers, watch here…..

Children wrote down questions they had during the lecture and got answers back to them the next day. Had to break out the dictionary to find the etiology of the word “cooties”.

Dawn speaks on “Undergraduate Research Opportunities” for the McMaster Undergraduate Research S

Dawn was delighted to be invited to speak at an information night organized by the McMaster Undergraduate Research in Science Association (MURSA). She presented her perspectives on what she might be looking for in an undergraduate student, why PIs/Professors take on undergraduates and once an undergraduate gets a position, what they need to do to be successful. For her presentation, click here. To learn more about the MURSA see their webpage or Facebook page

Dawn presents her perspectives on why a PI might take an undergraduate researcher and what an undergraduate might do to obtain a research position and be successful in research.


Dawn to talk at the Dept. of Chemical Engineering, Nov. 26, 2009

I am looking forward to presenting some recent, unpublished data at the Department of Chemical Engineering at McMaster. This will be a very different audience than usual but I suspect that there will be many overlapping interests as macrophages are involved in biopolymer and nanoparticle recognition and detrimental host responses. Below is the title & abstract of the talk.

Macrophage scavenger receptors: role in adhesion, uptake & migration.
Macrophages are tissue-resident white blood cells that are essential for detection of pathogens, clearance of modified host products and recognition of foreign bodies. Macrophages recognize both host and foreign ligands via surface expressed receptors. The result of this recognition may be a pro-inflammatory response, phagocytosis, or differentiation & adhesion. Although macrophage responses are essential for host defence and tissue homeostasis, they can also be detrimental when the macrophage is unable to clear foreign particles such as implants or environmental and synthetic particles. The scavenger receptors are macrophage receptors that have the unusual capacity of recognizing modified self proteins, pathogens and foreign particulates. We aim to determine how these receptors transmit signals to the cell and how this signaling affects macrophage adhesion, phagocytosis & endocytosis (uptake) and migration.
