Monocytes play an important part in the clearance of pathogens during infection. Yasmine Belkaid and her colleagues now report that inflammatory monocytes can also have a regulatory role. Specifically, these cells can mitigate the tissue damage induced by neutrophils during infection of mice with Toxoplasma gondii by releasing prostaglandin E2 in response to commensal bacteria.
