Product Focus: LEXSY gene fusion vaccines

Jena Bioscience GmbH's LEXSY was used for the development of a live tri-gene fusion recombinant L. tarentolae vaccine against experimental murine visceral leishmaniasis, based on L. donovani A2 antigen and cysteine proteinases CPA and CPB (Saljoughian et al., 2013). It was found that immunizations with this vaccine protected BALB/c mice against L. infantum challenge and were associated with a Th1-type immune response.
Cervical cancer is the third most prevalent cause of cancer in women worldwide and associated with human papilloma viruses (HPV). Recombinant LEXSY expressing gene fusions of HPV16 E7 antigen with GFP (Salehi et al., 2012) or chaperone gp96 regions (Hosseinzadeh et al., 2013) were found to significantly induce the levels of IgG2a and IFN╬│ in a C57BL/6 mice model. Furthermore, live L. tarentolae-E7-CT(gp96) vaccine indicated significant protective effects as compared to control groups.
