Dr Bowdish is the Canadian Lung Association’s spokesperson for World Pneumonia Day (November 12, 2018). Here she discusses the importance of being vaccinated for pneumonia….
She also speaks to Zoomer Magazine about pneumonia, vaccinations and the aging immune system here…

Myeloid-Derived Suppressor Cells in Aged Humans
Myeloid-derived suppressor cells (MDSCs) are immature myeloid cells whose
immunosuppressive activities contribute to cancer and other diseases. MDSCs
appear to increase with age, and this presumably contributes to immunosuppression
and the increased incidence of certain diseases. Why MDSCs increase with
age is not entirely clear. Herein we present evidence that MDSC expansion is due
in part to age-related changes in hematopoiesis, including the acquisition of
mutations that favor myelopoiesis, which are compounded by changes in the
aging microenvironment that favor the production of MDSCs.
Congratulations to the newly minted Dr. Loukov on successfully defending her thesis entitled “Age-Associated Inflammation impairs Myeloid Development and Monocyte & Macrophage Function”!
The newly minted Dr. Loukov drinks from the chalice.
Dessi celebrates her thesis defence with one of her mentors Dr. Mark McDermott.
Two doctors.
The Bowdish lab was very proud to host Anika Gupta, a high school student, for her Bay Area Science and Engineering Fair (BASEF) project.
Her project was entitled “Quantifying Lung Macrophages to Understand Increased Susceptibility to Bacterial Pneumonia with Age.”
Anita won the Dr. Doyle Biology Award for the best Biology project, a Gold merit award as well as the Pinnacle Award for the Third Best in Fair and a sponsored Trip Award to compete in the Intel International Science and Engineering Fair in Pittsburgh, Pennsylvania in May!
Way to go Anika!

It’s a very serious illness, especially for #Zoomers @libbyznaimer talks with expert @MsMacrophage Dawn Bowdish, Chair of #Aging & Immunity @McMasterU to find out everything we need to know about #Pneumonia at 12 and we take your calls as well at: 416-360-0740 or 1-866-740-4740

Listen to the interview here.
Dr. Dawn Bowdish and her PhD student Dessi Loukov collaborated with Dr. Monica Maly and Sara Karampatos (Rehabilitation Science) and found that monocytes were more activated and pro-inflammatory in women with osteoarthritis, and that elevated inflammation and body mass index were associated with increased monocyte activation. Further, the team found that women with osteoarthritis and more activated monocytes experienced worse pain than individuals with less activated monocytes. These findings highlight the importance of modulating inflammation and body mass to manage osteoarthritis and open up new avenues for therapeutic research.
