This paper outlines how microRNA- (miR-)155 regulates the immune response to S. pneumoniae colonization in the nasal passages of mice by stimulating the differentiation of Th17 cells.

This paper demonstrates that there are host- and strain- specific responses to isolates of the Streptococcus milleri/anginosis group and that isolates from invasive disease appear to be more immunostimulatory than those from commensal relationships.
Funding from the province of Ontario supports two new graduate students!
Bowdish lab receives funding from the province of Ontario to train two new graduate students! Avee Naidoo (MSc) and Dessi Loukov, who will be starting a PhD in Sept 2013, will be studying how age-associated inflammation predisposes older adults to pneumonia.

“Immunosenescence & novel vaccination strategies for the elderly” 2013. Dorrington et al. Frontiers in Immunology
What is the best way to reduce infectious disease in the elderly? Vaccination! Unfortunately the aging immune system presents a number of challenges for vaccine development. Bowdish lab PhD candidate Mike Dorrington discusses them in this review and presents a case for developing novel vaccines that work within the constraints of the aging immune system.
