launch in mice without STAT1 because there weren’t enough macrophages in the liver for the parasite to infect, and these are the very immune cells that are essential for successful survival and replication of Leishmania parasites in the host,’ Satoskar said.

The researchers aren’t suggesting that STAT1 activation should be stopped in order to prevent visceral leishmaniasis. However, they want to figure out how this protein’s absence keeps macrophages from flooding into the liver during the early stages of infection.

If they can do that, it may be possible to create a drug to prevent L. donovani from infecting the liver and the spleen. Although there are medications available to treat the symptoms of visceral leishmaniasis, they can be toxic and sometimes expensive for the people who need them the most.

Satoskar conducted the study with colleagues from Ohio State, Montreal General Hospital in Montreal, Canada, and with the Harvard School of Public Health and Harvard Medical School.

This work was supported by grants from the National Institutes of Health, the National Institute of Dental and Cranial Research, the National Science Foundation and the Ellison Medical Foundatin.
