Modulation of fibroblast behavior by Leishmania: a pathway to understanding disease progression in cutaneous leishmaniasis [PDF]

BMC Microbiology
Leishmaniasis is a parasitic infection caused by obligatory intracellular protozoa of the Leishmania genus. Macrophages are the main cell for Leishmania parasites that play a key role in immune response against it.
