    The impact of intermittent preventive treatment in school aged children with dihydroartemisinin piperaquine and artesunate amodiaquine on IgG response against six blood stage Plasmodium falciparum antigens. by Eric Lyimo, Geofrey Makenga, Louise Turner, Thomas Lavstsen, John P A Lusingu, Jean-Pierre Van Geertruyden, Daniel T R Minja, Christian W Wang, Vito Baraka

    Published 2025-01-01
    “…However, the implementation IPT strategies raises a genuine concern, intervening the development of naturally acquired immunity to malaria which requires continuous contact with parasite antigens. This study investigated whether dihydroartemisinin-piperaquine (DP) or artesunate-amodiaquine (ASAQ) IPT in schoolchildren (IPTsc) impairs IgG reactivity to six malaria antigens. …”

    Production and characterization of nervous necrosis virus vaccine antigens in wild type and CRISPR/Cas9 genome edited Nicotiana benthamiana and edible crop lettuce Lactuca sativa by Iva Andrasevic, Hang Su, Espen Rimstad, Jihong Liu Clarke

    Published 2025-03-01
    “…Plant platforms have several advantages and have been proposed as an alternative biomanufacturing method for vaccine antigens. In the present study, we report: (1) selection and design of recombinant plasmids encoding the capsid proteins (CPs) of two genotypes of NNV, red-spotted grouper nervous necrosis virus (RGNNV) and striped jack nervous necrosis virus (SJNNV); (2) design and optimization of plasmids for transient expression of NNV vaccine antigens in wild type Nicotiana benthamiana, CRISPR/Cas9 genome edited Nicotiana benthamiana and Lactuca sativa; (3) test of different Agrobacterium strains (LBA4404 and AGL1) for effective production of NNVCPs; (4) the expression patterns of NNVCPs over time post infiltration for different plants and cultivars; (5) successful production of NNV antigens in N. benthamiana lines and lettuce cultivars, indicating the potential of the plants as antigen producers in the development of a plant-based vaccine against VNN.…”

    Cloning, expression, and purification of fusion antigens MPT83 and ESAT6 from the local strain of Mycobacterium tuberculosis in Escherichia coli as a seed vaccine candidate against tuberculosis by Rusdina Bte Ladju, Ahyar Ahmad, Abdul Karim, Rugaiyah Arfah, Rosana Agus, Najdah Hidayah, Muhammad Nasrum Massi, Astutiati Nurhasanah, Harningsih Karim, Irda Handayani

    Published 2025-03-01
    “…The existence of the appropriate recombinant Rv2873 + Rv3875 fusion genes was confirmed through the observation of a band of 948 base pairs in the colony PCR product containing fusion antigens. A band measuring 3966 base pairs was observed in the recombinant plasmid pGEM-T Easy- Rv2873+Rv3875, supporting the presence of the desired fusion genes target. …”
