Summary: Cerebral malaria, the deadliest complication of Plasmodium parasite infection, may be caused by neuroinflammation leading to cerebral edema and blood-brain barrier dysfunction. Plasmodium MIF can enhance inflammatory response by signaling through host MIF receptor CD74, contributing to the development of cerebral malaria. Studies using CD74 deficient hosts and PMIF deficient parasites suggest a potential mechanism for the onset of experimental cerebral malaria and liver stage Plasmodium development.

Summary: Hundreds of thousands of lives are lost each year due to brain damage caused by malaria. The majority of these deaths occur in sub-Saharan African children. Host genetic background plays a crucial role in determining the course and outcome of the disease.

Summary: An untargeted metabolomics approach was used to identify the changes in metabolic pathways and metabolites in the serum of mice with different pathological stages of malaria. The study provides insights into the host biology during malaria and could be helpful for the selection of animal models for evaluating diagnostic and therapeutic interventions against malaria.

Summary: Chloroquine remains the most effective drug for malaria treatment, although resistance to it has emerged. This study focuses on the synthesis of quinoline derivatives to develop new antimalarials. Compound 3 showed promising activity against malaria, inhibiting parasite growth and protecting against severe malaria development.

Summary: Cerebral malaria is a severe complication of malaria infection, with a high mortality rate. This study found that a combination of a statin and an angiotensin II receptor blocker as adjunctive therapy to conventional antimalarial drugs reduced endothelial activation and improved survival rates in a mouse model of CM.

Summary: This study validated the use of optical clearing technique for comprehensive 3D cellular-level analysis of dental pulp cells, revealing unique 3D spatiotemporal changes in normal and pathological conditions. Specifically, an increase in CD11c+ dendritic cells was observed in the dental pulpitis model, showing a distinct spatial 3D arrangement within 12 hours after irritation.

Summary: This study reveals that the microbiota colonizing the lung can promote respiratory distress syndrome and mortality during malaria infections. Parasite sequestration in the lung results in sustained immune activation and production of anti-inflammatory cytokine compromises microbial control, leading to severe lung disease. Clearance of bacteria prevents MA-ARDS-associated lethality. Hence, the balance between the host's anti-inflammatory response and microbial control should be considered when intervening against respiratory complications.

Summary: This study reveals the crucial role of XAF1 in enhancing interferon-induced apoptosis and combating RNA virus infections. XAF1 stabilizes IRF1 protein and induces the expression of antiviral genes, thereby strengthening the host's antiviral innate immunity.

Summary: The discovery of a Dicer isoform called antiviral Dicer provides protection for tissue stem cells against RNA viruses, shedding light on the molecular regulation of antiviral RNAi in mammalian innate immunity. Different cell-intrinsic antiviral pathways can be tailored to the differentiation status of cells.

Summary: Regions with endemic helminth infections have lower COVID-19 severity and mortality. Research shows that lung remodeling caused by previous infection with a lung-migrating helminth, Nippostrongylus brasiliensis, enhances viral clearance and survival in mice infected with SARS-CoV-2. This protection is linked to increased accumulation of specific CD8(+) T cells and is dependent on the presence of macrophages with a type 2 transcriptional and epigenetic signature.

Summary: The study found that endothelial CD146 plays a crucial role in experimental cerebral malaria, with its overexpression leading to the aggregation of infected red blood cells and lymphocytes, thereby disrupting BBB integrity. Deletion of endothelial CD146 or treatment with anti-CD146 antibody can prevent severe symptoms of cerebral malaria, and combined treatment with anti-CD146 antibody and antiparasitic drugs can improve cognition and memory in patients with cerebral malaria.
