Neutrophils are abundant in the circulation and are one of the immune system's first lines of defense against infection. There has been substantial work carried out investigating the role of neutrophils in malaria and it is clear that during infection neutrophils are activated and are capable of clearing malaria parasites by a number of mechanisms. This review focuses on neutrophil responses to human malarias, summarizing evidence which helps us understand where neutrophils are, what they are doing, how they interact with parasites as well as their potential role in vaccine mediated immunity. We also outline future research priorities for these, the most abundant of leukocytes.

Purpose: Malaria remains a major global health challenge, particularly in sub-Saharan Africa and low- and middle-income countries (LMICs), contributing substantially to mortality and morbidity rates. In resource-limited settings, access to specialized diagnostic tests is often restricted, making basic blood analysis a valuable diagnostic tool. This study investigated the correlation between malaria infection and full blood count values in a rural region of Ghana during the 2022 rainy season, aiming to highlight diagnostic insights available from routine blood analyses.

In this study, outbred pregnant CD1 mice with semi allogeneic fetuses were infected with transgenic or mock-inoculated by mosquito bite at either embryonic day (E) 6 (first trimester-equivalent) or 10 (second trimester- equivalent) and compared with non-pregnant females. -infected mosquitoes had greater biting avidity for E10 dams than uninfected mosquitoes, which was not apparent for E6 dams nor non-pregnant females.

Malaria remains a significant health threat in tropical and subtropical regions. The immune response to Plasmodium falciparum involves both humoral and cellular components, including phagocytosis by neutrophils. However, observing phagocytosis through light microscopy is uncommon.

Most deaths among children under 5 years occur within the first 24 hours of hospital admission from preventable causes such as diarrhea, pneumonia, malaria, and HIV/AIDS. The predictors of these deaths are not yet well documented in our setting. This study aimed to describe the patterns and predictors of these mortalities among children aged 1-59 months at a regional hospital in South Western Uganda.

Interferon γ-induced protein 10 kDa (IP-10) or C-X-C motif chemokine 10 (CXCL10) is produced and secreted from specific leukocytes such as neutrophils, eosinophils, and monocytes, which play key roles in the immune response to Plasmodium infections. This systematic review aimed to collate and critically appraise the current evidence on IP-10 levels in malaria patients. It provided insights into its role in malaria pathogenesis and potential as a biomarker for Plasmodium infections and disease severity.
