Pharmacological blockade of the chemokine receptor CCR1 protects mice from systemic candidiasis of hematogenous origin

Abstract

Systemic candidiasis is a leading cause of nosocomial bloodstream infection with a high mortality rate despite treatment. Immune-based strategies are needed to improve outcomes. We previously reported that genetic deficiency in the chemokine receptor CCR1 improves survival and ameliorates tissue damage in Candida-infected mice. Here, we found that treatment of immunocompetent Candida-infected mice with the CCR1-selective antagonist BL5923 improves survival, decreases the kidney fungal burden, and protects from renal tissue injury.
