In Ethiopia, malaria control has been complicated due to resistance of the parasite and its vectors to the current drugs. Therefore, new drugs are required to avert the problem posed by drug-resistant Plasmodium strains. There is need to investigate alternative sources of antimalarial agents and plants are potential source of antimalarial drugs. This study aimed to investigate the antimalarial activity of the leaves of N. congesta crude extract (hydromethanolic extract) and solvent fractions (n-hexane, chloroform, and aqueous fractions of crude extract) traditionally used to treat malaria in many parts of Ethiopia.
Despite the extensive endeavours, developing an effective malaria vaccine remains as a great challenge. Apical membrane antigen 1 (AMA-1) located on the merozoite surface of parasites belonging to the genus Plasmodium is involved in red blood cell invasion.
The essential and distinct functions of Protein Phosphatase type 1 (PP1) catalytic subunit in eukaryotes are exclusively achieved through its interaction with a myriad of regulatory partners.
More than 200 medicinal plants including Euphorbia abyssinica are utilized for treatment of malaria in Ethiopian traditional medical practices. However, the safety, efficacy and quality of these medicinal plants are largely unknown. Pharmacological and toxicological investigations of these plants are among the prioritized issues in every country. The aim of this study was, therefore, to evaluate the anti-malarial activity of Euphorbia abyssinica root extract against Plasmodium berghei infection in mice.
Reverse genetics approaches have become powerful tools to dissect the biology of malaria parasites. In a previous study, development of an in vitro drug selection method for generating transgenic parasite of Plasmodium berghei was reported. Using this method, two novel and independent selection markers using the P. berghei heat shock protein 70 promoter was previously established. While the approach permits the easy and flexible genetic manipulation of P. berghei, shortcomings include a low variety in promoter options to drive marker gene expression and increased complexity of the selection procedure. In this study, addressing these issues was attempted.
Malaria in pregnancy significantly alters the expression of SLC transporters in maternal and foetal tissues as well as the placenta, regardless of L‐arginine supplementation.
The results suggest that the impact of ITNs may be weaker for malaria-infected than for uninfected mosquitoes.
The effects of the ME on the parasite-host interactions appeared to be mouse strain-dependent, but also related to the ripening stage of the neem fruits, as only the unripe fruit seed kernel extracts displayed appreciable bioactivity.
The use of microbial symbiont to reduce the competence of vectors involved in disease transmission has gained much importance in recent years as an emerging alternative approach towards disease control.
Artemether (ATM) cardiotoxicity, its short half-life and low oral bioavailability are the major limiting factors for its use to treat malaria.
