anti-malarial

Here, we used surrogate T cell activation markers to identify and track whole-parasite, RAS-vaccine-induced effector and memory CD8 T cell responses. Our data show that the differential susceptibility of RAS-immune inbred mouse strains to Plasmodium berghei or P. yoelii sporozoite challenge does not result from host- or parasite-specific decreases in the CD8 T cell response.

A system of this type would allow users to answer several questions. Is this medicine what it is supposed to be? Can it be used to treat locally encountered malaria?

Malaria remains the most prevalent vector-borne infectious disease and has the highest rates of fatality. Current antimalarial drug strategies cure malaria or prevent infections but lack a sustained public health impact because they fail to expedite the acquisition of protective immunity.

We have purified the recombinant Pv 6-oxopurine (PRTase) and compared its properties with the human and Pf enzymes. The Pv enzyme uses hypoxanthine and guanine with similar catalytic efficiency to the Pf enzyme but xanthine is not a substrate, hence we identify this enzyme as PvHGPRT.

Radiation-attenuated Plasmodium sporozoites (RAS) are the only vaccine shown to induce sterilizing protection against malaria in both humans and rodents.

A series of dimeric 1,3-cyclohexanedione oxime ethers were synthesized and found to have significant antiplasmodial activity with IC50’s in the range 3–12 μM.

The public health and private retail sector are important complementary sources of treatment in rural Tanzania. Ensuring the availability of ALu in the private retail sector is important for its successful uptake.

Genotypes and gene copy number were assessed for pfcrt, pfmdr1, pfmdr2, pfmrp genes. In addition, the number of DNNND, DDNHNDNHNN repeats in pfnhe-1 ms4760 and the ms4760 profile were determined for each strains of P. falciparum.

Anti-plasmodial activities of extracts of B. elegans and S. surattense are reported for the first time.

A new phenylpropanoid conjugated iridoid together with four known congeners was isolated from Morinda morindoides, used for the therapy of malaria traditionally in some African countries, as anti-malarial principles through bioassay-guided separation.
