| imported cutaneous leishmaniasis caused by leishmania major in a chinese laborer who worked in saudi arabia. | we report an imported case of cutaneous leishmaniasis in a 37-year-old man from saudi arabia caused by leishmania major. he presented with non-healing nodulo-ulcerative lesions with a "volcanic crater" on the lower limbs. it was clearly cutaneous leishmaniasis - a rare disease in china - as reflected by the patient's clinical history, the lesions' morphology, histopathological examination, culture and pcr analysis of the lesions. the patient was completely cured after two cycles of sodium stibog ... | 2017 | 27438208 |
| amiodarone triggers induction of apoptosis in cutaneous leishmaniasis agents. | leishmaniasis is a parasitic disease that is an important problem of public health worldwide. the aim of this study was to assess the cytotoxic effects of amiodarone (amd) on leishmania tropica (mhom/af/88/kk27) and l. major (mrho/ir/75/er) promastigotes and to observe the programmed cell death features. the colorimetric mtt assay was used to find l. tropica and l. major viability and the obtained results were expressed as 50% inhibitory concentration (ic50). annexin-v fluos staining was perform ... | 2017 | 27553974 |
| genomic cartography and proposal of nomenclature for the repeated, interspersed elements of the leishmania major sider2 family and identification of sider2-containing transcripts. | the genomes of most eukaryotic organisms contain a large number of transposable elements that are able to move from one genomic site to another either by transferring of dna mobile elements (transposons) or transpose via reverse transcription of an rna intermediate (retroposons). an exception to this rule is found in protists of the subgenus leishmania, in which active retroposons degenerated after a flourishing era, leaving only retroposon remains; these have been classified into two families: ... | 2017 | 28034676 |
| in vitro antileishmanial activity of novel azoles (3-imidazolylflavanones) against promastigote and amastigote stages of leishmania major. | leishmaniasis is a protozoan infectious disease widely distributed all around the world. first line drugs including antimoniales are insufficient due to resistance in endemic areas and high toxicity. azole antifungals like ketoconazole (kcz) are also used as antileishmanial agents for several decades. in the present study, we evaluated in vitro antileishmanial effects of new azole antifungals namely 3-imidazolylflavanones (ifs) and their oximes (ifos) against leishmania major (l. major) parasite ... | 2017 | 28017860 |
| a novel protein coding potential of long intergenic non-coding rnas (lincrnas) in the kinetoplastid protozoan parasite leishmania major. | cutaneous leishmaniasis (cl) is caused by a kinetoplastid protozoan parasite leishmania major, as a skin ulcer at the site of the sandfly bite. cl is curable and in most cases ulcers heal spontaneously within three to six months leaving a scar and disfiguration. complete genome of l. major was reported in 2005 at the very initial phase of kinetoplastid parasite genome sequencing project. presently, l. major genome is most studied and comprehensively annotated genome and therefore, it is being us ... | 2017 | 27988178 |
| parasites dampen dendritic cell activation to ensure their survival. | dendritic cells (dcs) are critical for induction of protective immunity against leishmania major. however, dc activation occurs only several weeks after parasite transmission. parasites synthesize a macrophage-inducible c-type lectin (mincle) ligand. engagement of mincle by the parasite ligand dampens dc activation, thus delaying induction of interferon-γ-producing t cells responsible for parasite eradication. | 2017 | 27988097 |
| interplay between a cytosolic and a cell surface carbonic anhydrase in ph homeostasis and acid tolerance of leishmania. | leishmania parasites have evolved to endure the acidic phagolysosomal environment within host macrophages. how leishmania cells maintain near-neutral intracellular ph and proliferate in such a proton-rich mileu remains poorly understood. we report here that, in order to thrive in acidic conditions, leishmania major relies on a cytosolic and a cell surface carbonic anhydrase, lmca1 and lmca2, respectively. upon exposure to acidic medium, the intracellular ph of the lmca1(+/-), lmca2(+/-) and lmca ... | 2017 | 28062849 |
| leishmania hasp and sherp genes are required for in vivo differentiation, parasite transmission and virulence attenuation in the host. | differentiation of extracellular leishmania promastigotes within their sand fly vector, termed metacyclogenesis, is considered to be essential for parasites to regain mammalian host infectivity. metacyclogenesis is accompanied by changes in the local parasite environment, including secretion of complex glycoconjugates within the promastigote secretory gel and colonization and degradation of the sand fly stomodeal valve. deletion of the stage-regulated hasp and sherp genes on chromosome 23 of lei ... | 2017 | 28095465 |
