Studies on the glycosylation of metacyclic trypanosomes

LSTM |

The development of Trypanosoma brucei within the tsetse vector is accompanied by the expression of several stage-specific families of GPI-anchored surface glycoproteins. We recently discovered that saliva from T.brucei-infected tsetse flies is enriched with Brucei Alanine-Rich Proteins (BARP), VSG and a novel family of GPI-anchored surface glycoproteins. The latter are phylogenetically grouped within the Clade IV of family 50 of trypanosome surface proteins and are encoded by five paralogs, whose products are over 90% identical in sequence. Immunofluorescence and transcript analysis showed that Clade IV proteins are expressed on the surface of metacyclic trypanosomes and also on epimastigotes and pre-metacyclic forms although in lower abundance. This expression pattern opposes that of BARP, which is highly expressed in the epimastigote stage and diminishes during differentiation to metacyclics. Because Clade IV proteins are almost identical in sequence and are heavily expressed in the metacyclic stage, we named them Metacyclic Invariant.

Evaluation and Control of Cutaneous Leishmaniasis in KSA

LSTM |

Cutaneous Leishmaniasis (CL) is exclusively transmitted by the bite of a female sand fly. In collaboration with the Saudi Arabian Ministry of Health, we have developed a programme aiming to prevent and control CL in this country. The programme focuses, among other aspects, in developing a rapid diagnostic test based on the patient’s anti-alpha-Gal response, and in identifying markers for disease exposure. We recently found evidence that treatment efficacy against Old World CL varies with parasite species, geographical locations and the development of secondary infections. This has implications on the treatment of this debilitating disease. The severity of a leishmaniasis ulcer partly depends on the patient’s previous exposure to sand fly bites. This explains the increased protection against CL in individuals living in CL-endemic areas and supports development of potential vaccine models based on sand fly salivary proteins. Furthermore, Old World CL patients produce high levels of anti-Gal antibodies (i.e. recognise terminal alpha-galactosyl epitopes). This discovery is currently being exploited for the making of rapid diagnostic tools and a potential protective glycovaccine model against CL. We hope that these tools can soon be applied in other CL-endemic countries, including refugee settings.

Field Validation of Wb123 monoplex, Haiti

To compare the performance of antigen (FTS) and antibody (Wb123 monoplex) tools in programmatic settings (TAS).

Preliminary Findings and Lessons Learned

The goal of this study is to compare the performance of antigen (FTS) and antibody (Wb123 monoplex, Wb123 ELISA, multiplex) tools in programmatic settings (TAS). In order to strengthen the existing TAS platform we need to better understand which diagnostic indicator(s) are best-suited for making programmatic decisions. The TAS was conducted in Trou de Nord and Plaisance EUs.  Both EUs passed the TAS, but positive FTS were identified (4 and 2, respectively). However the Wb123 RDT found ZERO positive children, of the over 2000 tested. While the Wb123 ELISA testing is still ongoing, this initial result agrees with findings from other studies, all of which suggest that the Wb123 RDT is too insensitive a tool to be of programmatic use.
