Over the past five years, published issues of PPAR Research have covered a broad expanse of physiological functions and clinical importance of PPARs. Topics spanned reviews of PPARs function in specific cell and tissue types, their roles in a host of diseases, and their rich pharmaceutical potential. Yet, no issue so far has been dedicated to the role of PPARs in parasitic infections. Clearly, the immunomodulatory capacity of PPARs can be influential in the delicate balance between host defense and parasite survival.

Accordingly, this issue will focus on different aspects of PPARs in relationship to protozoan and metazoan parasites: biology, immunology, pathology, and therapy.

We invite authors to present original research articles or reviews that address any aspect of the role of PPARs and parasitic diseases. Potential topics include, but are not limited to:

• PPAR expression during infections by parasitic protozoans and helminthes
• Intracellular survival of pathogens in relation to PPAR status
• PPAR protection and elimination of parasites
• Lipid mediators and their modulation of antiparasitic immune response
• PPAR ligands and parasitic diseases
