Vacatures - PhD tumor immunology of peritoneal metastasis - Amsterdam UMC Colorectal cancer with peritoneal metastases has a particularly poor prognosis. In this KWF-funded project, you will investigate how glycan structures affect immune responses in peritoneal metastasis and whether glycan inhibition can restore anti-tumor immunity.

Our lab is hiring a PhD student to investigate how glycans affect antitumor immune responses in metastases and how this can be modulated to improve immunotherapy! More info here πŸ‘‡

Shigella was the leading cause of diarrheal disease during World War One; and more than 100 years later, it continues to cause approximately 200 million cases and 216,000 deaths per year around the globe. Shigella is a leading cause of moderate to severe diarrhea in children less than five years of age in low- and middle-income nations, and significant disease occurs throughout Europe and North America due to sexual transmission, food borne and water borne outbreaks, and high incidence in homeless populations. The lack of a licensed vaccine, coupled with alarming increases in antimicrobial resistance, has led the World Health Organization to declare Shigella a priority pathogen for which research into new therapeutics are urgently needed.
