MAP kinase phosphatase-2 plays a critical role in response to infection by Leishmania mexicana

, 2010
In this study we generated a novel dual specific phosphatase 4 (DUSP4) deletion mouse using a targeted deletion strategy in order to examine the role of MAP kinase phosphatase-2 (MKP-2) in immune responses.

Iron metabolism in trypanosomatids, and its crucial role in infection. [PDF]

, 2010
Iron is almost ubiquitous in living organisms due to the utility of its redox chemistry. It is also dangerous as it can catalyse the formation of reactive free radicals - a classical double-edged sword.

Phlebotomine fauna (Diptera: Psychodidae) of an American cutaneous leishmaniasis endemic area in the state of Mato Grosso do Sul, Brazil

Memorias do Instituto Oswaldo Cruz, 2009
The occurrence of an outbreak of cutaneous leishmaniasis associated with Leishmania (Leishmania) amazonensis in the municipality of Bela Vista, state of Mato Grosso do Sul, Brazil, and the absence of information on its vectors in this area led the ...

CENTRAL NERVOUS SYSTEM INVOLVEMENT IN EXPERIMENTAL INFECTION WITH LEISHMANIA (LEISHMANIA) AMAZONENSIS

The American Journal of Tropical Medicine and Hygiene, 2003
We describe the pathologic alterations of the central nervous system (CNS) observed in experimental tegumentary leishmaniasis in BALB/c and Swiss mice. The mice were subcutaneously infected with 104 amastigotes of Leishmania (Leishmania) amazonensis. Animals were killed and brains were removed for histologic and immunocytochemical studies.

Investigating the role of the Leishmania (Leishmania) major HASP and SHERP genes during metacyclogenesis in the sand fly vectors, Phlebotomus (Phlebotomus) papatasi and Ph. (Ph.) duboscqi [PDF]

, 2013
Leishmania parasites are the causative agents of a diverse spectrum of infectious diseases termed the leishmaniases. These digenetic parasites exist as intracellular, aflagellate amastigotes in a mammalian host and as extracellular flagellated ...

Studies on immunology of Leishmania mexicana

, 2007
Leishmaniasis is a worldwide disease prevalent in many tropical and sub tropical countries. Treatment of Leishmaniasis by chemotherapy is not wholly effective and is usually accompanied by unpleasant side effects.

Leishmania infantum proteophosphoglycans regurgitated by the bite of its natural sand fly vector, Lutzomyia longipalpis, promote parasite establishment in mouse skin and skin-distant tissues

, 2010
We demonstrate that a proteophosphoglycan-rich gel secreted by Leishmania infantum inside the midgut of Lutzomyia longipalpis sand flies (promastigote secretory gel) is regurgitated along with an average dose of 500 L.

Neutrophils Reduce the Parasite Burden in Leishmania (Leishmania) amazonensis-Infected Macrophages

PLoS ONE, 2010
Studies on the role of neutrophils in Leishmania infection were mainly performed with L. (L) major, whereas less information is available for L. (L) amazonensis. Previous results from our laboratory showed a large infiltrate of neutrophils in the site of infection in a mouse strain resistant to L. (L.) amazonensis (C3H/HePas).
