| Abstract |
We previously identified a Leishmania (L.) major large RAB GTPase (LmlRAB), a new atypical RAB GTPase protein. It is highly conserved in Leishmania species while displaying low level of homology with mammalian homologues. Leishmania small RAB GTPases proteins have been involved in regulation of exocytic and endocytic pathways whereas the role of large RAB GTPases proteins has not been characterized yet. We report here the immunogenicity of both recombinant rLmlRAB and rLmlRABC, in individuals with immunity against L. major or L. infantum. PBMC were isolated from individuals cured of L. major (CCLm) or from healthy individuals. The latter were subdivided into high or low IFN-γ responders. Healthy high IFN-γ responders, considered as asymptomatics, were living in an endemic area for L. major (HHRLm) or L. infantum (HHRLi). Healthy low IFN-γ responders (HLR) were considered as naïve controls. Cells from all volunteers were stimulated with rLmlRAB or rLmlRABC. Cytokines were analysed by CBA and ELISA and phenotypes of IFN-γ-producing cells were analysed by flow cytometry. Both rLmlRAB and rLmlRABC induced high significant levels of IFN-γ in CCLm, HHRLm and HHRLi groups. Phenotype analysis of rLmlRAB and rLmlRABC-stimulated T cells in CCLm individuals showed a significant increase in the percentage of specific IFN-γ-producing CD4+ and CD8+ T cells. rLmlRAB induced significant granzyme B levels in CCLm and HHRLm. Low but significant granzyme B levels were detected in naïve group. IL-10 was detected in immune and naïve individuals. We showed that rLmlRAB protein and its divergent carboxy-terminal part induced a predominant Th1 response in individuals immune to L. major or L. infantum. Our results suggest that rLmlRAB and rLmlRABC proteins are potential cross-species vaccine candidates against cutaneous and visceral leishmaniasis. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 April 2017.
All research outputs
#17,886,132
of 22,963,381 outputs
Outputs from Parasites & Vectors
#3,839
of 5,485 outputs
Outputs of similar age
#220,768
of 310,087 outputs
Outputs of similar age from Parasites & Vectors
#127
of 158 outputs
Altmetric has tracked 22,963,381 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 5,485 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.7. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 310,087 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 24th percentile – i.e., 24% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 158 others from the same source and published within six weeks on either side of this one. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
