Osteopontin in the host response to Leishmania amazonensis [PDF]
BMC Microbiology, 2019 Leishmania (L.) spp are intracellular eukaryotic parasites responsible for cutaneous or visceral leishmaniasis, replicating predominantly in macrophages (MF). In C57BL/6 mice virulence with L. amazonensis has been associated with inhibition of Th1 immune responses and an uncontrolled lesion development, whereas DBA/2 mice control any lesion.

Effect of 3-Carene and the Micellar Formulation on Leishmania (Leishmania) amazonensis
Tropical Medicine and Infectious Disease, 2023 Leishmaniases are neglected tropical diseases caused by obligate intracellular protozoa of the genus Leishmania. The drugs used in treatment have a high financial cost, a long treatment time, high toxicity, and variable efficacy. 3-Carene (3CR) is a hydrocarbon monoterpene that has shown in vitro activity against some Leishmania species; however, it ...

Leishmania (Leishmania) amazonensis Infection in Mice Treated With FTY720
Transplantation Proceedings, 2010 In transplantation, parasite diseases are transmitted from the donor, or appear as de novo infections, or activate from a dormant insource as a consequence of immunosuppression. Clinical findings have shown that an intact immune system is crucial to prevent recurrence of Leishmania infection.

Leishmania amazonensis Infection in Nude Mice.
Experimental Animals, 1999 Leishmania amazonensis is an intracellular protozoan parasite of macrophages. Cutaneous leishmaniasis in an immunocompetent host begins as papules or nodules followed by ulceration at the site of promastigote inoculation. In this study, the pathological changes of cutaneous leishmaniasis lesions in T cell deficient nude mice were examined.

Role of Leishmania (Leishmania) amazonensis amastigote glycosphingolipids in macrophage infectivity [PDF]
Brazilian Journal of Medical and Biological Research, 2007 The role of glycosphingolipids (GSLs) present in amastigote forms of Leishmania (Leishmania) amazonensis during infection of macrophages was analyzed, with particular emphasis on GSLs presenting the terminal Galpss1-3Galpa disaccharide. Macrophage invasion by L.
