Interferon-gamma (IFN-gamma) has been suggested to play an important role in the pathogenesis of malaria. To examine possible association of the IFN-gamma receptor 1 (IFNGR1) polymorphisms with cerebral malaria, 312 adult patients with Plasmodium falciparum malaria (203 mild and 109 cerebral malaria patients) living in northwest Thailand were genotyped for six single nucleotide polymorphisms (SNPs) including -56T/C (rs2234711) and a microsatellite marker in IFNGR1. A case-control association analysis failed to detect significant association between the IFNGR1 polymorphisms and cerebral malaria, thus implying that the IFNGR1 polymorphism may not be a major genetic factor influencing the development of cerebral malaria in the Thai population. These data also provide useful information for future genetic studies of IFNG polymorphisms in Thai patients.

Background: Malaria is responsible for 580,000 deaths among children under 5, or 95% of all malaria deaths per year globally. Seasonal Malaria Chemoprevention (SMC) is a malaria control intervention in Togo and other African countries targeting children under 5 years old during the peak malaria transmission season. Delaying access to healthcare for children with malaria can result in serious health problems, including heightened morbidity and mortality, complications related to cerebral malaria and anemia, as well as impaired cognitive development.

The application of neuroimaging techniques to patients with Plasmodium falciparum infection has uncovered a wide range of brain changes not only in cerebral malaria but also in noncomatose patients. We propose several hypotheses to unify findings across the spectrum of clinical malaria in adults and highlight the urgent need to evaluate potential long-term effects of cerebral alterations on neurocognition in this understudied age group.

The aim of this review is to highlight the biological potential of the aporphine class of alkaloids, crebanine, oxocrebanine and dehydrocrebanine and their molecular mechanisms, in order to understand their therapeutic potential in medicine. Using the phrases herbal medicine, aporphine, crebanine, oxocrebanine, dehydrocrebanine, and phytochemical, all of the scientific data on crebanine, oxocrebanine, and dehydrocrebanine used in this review was gathered from Google, Google Scholar, PubMed, Scopus, and Science Direct. Nevertheless, analytical techniques for the isolation, separation, and identification of crebanine, oxocrebanine, and dehydrocrebanine are also covered in this study.

Malaria remains a global health crisis, with the World Health Organization (WHO) reporting 241 million cases and 627,000 deaths worldwide in 2020, predominantly affecting Sub-Saharan Africa. The region accounted for 95% of cases and 96% of deaths, reflecting the immense challenges in malaria prevention and treatment. Schizont Egress Antigen-1 (PfSEA-1) is crucial in facilitating immune evasion and promoting the sequestration of infected red blood cells (RBCs), contributing to severe malaria symptoms, including cerebral malaria, and necessitates the urgent identification of novel or repurposed drugs targeting PfSEA1.

Cerebral malaria (CM), a life-threatening complication of Plasmodium falciparum infection, is characterized by the sequestration of infected erythrocytes in the brain microvasculature. Our study investigated the potential of repurposing anti-cancer BCR-ABL drugs, also known to be effective against P. falciparum blood-stage parasites, for mitigating inflammation and blood-brain barrier breakdown in CM.
