The immunobiology of Leishmania braziliensis infection [PDF]
Frontiers in Immunology, 2012 Leishmaniases are a group of diseases caused by protozoa of the genus Leishmania that affect millions of people worldwide. These diseases are caused by distinct Leishmania species, of which L.

Protection and Pathology in Leishmania braziliensis Infection
Pathogens, 2022 Leishmania killing is mediated by IFN-γ-activated macrophages, but IFN-γ production and macrophage activation are insufficient to control L. braziliensis infection. In American tegumentary leishmaniasis (ATL), pathology results from an exaggerated inflammatory response.

Experimental canine mucocutaneous leishmaniasis (Leishmania braziliensis braziliensis) [PDF]
Memorias do Instituto Oswaldo Cruz, 1988 Four mongrel dogs were intradermically inoculated with 3 x 10**6 Leishmania braziliensis braziliensis promastigotes. Three out of the four animals developed cutaneous lesions respectively 4, 7, and 8 months after. The fourth dog did not develop lesion at

Persistent Infections by Leishmania (Viannia) braziliensis [PDF]
Memorias do Instituto Oswaldo Cruz, 1997 Here we review the phenomenon of persistency in Leishmania (Viannia) braziliensis infections. In other Leishmania species where appropriate animal models exist, considerable advances in the understanding of basic immunologic mechanisms of persistency ...

Histone post-translational modifications of Leishmania braziliensis. [PDF]
Sci DataHistone post-translational modifications (hPTMs) constitute an epigenetic mechanism that plays a fundamental role in the regulation of gene expression in eukaryotic cells. In trypanosomatid parasites, such as Trypanosoma brucei, T. cruzi and Leishmania spp., gene regulation occurs mainly at the post-transcriptional level.

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

Identification of Serine Proteases from Leishmania braziliensis
Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 2007 Leishmania (V.) braziliensis is one of the most important ethiologic agents of the two distinct forms of American tegumentary leishmaniasis (cutaneous and mucosal). The drugs of choice used in leishmaniasis therapy are significantly toxic, expensive and are associated with frequent refractory infections.
