    Abstract Eukaryotic parasites (including parasitic protozoans, worms and arthropods) are more complex and heterogeneous organisms than pathogenic bacteria and viruses. This notion implies different evolutionary strategies of host exploitation. Typically, parasites establish long-term infections and induce relatively little mortality, as they often limit pathological changes by modulating host cells and downregulating adverse immune responses. Their pattern of distribution tends to be endemic rather than epidemic. Despite these seemingly benign traits, parasites usually cause substantial chronic morbidity, thus constituting an enormous socioeconomic burden in humans, particularly in resource poor countries, and in livestock worldwide. Parasite-induced fitness costs are an evolutionary force that can shape populations and contribute to species diversity.-

    Therefore, a thorough understanding of parasites and parasitic diseases requires detailed knowledge of the respective biochemical, molecular and immunological aspects as well as of population genetics, epidemiology and ecology. This Research Topic (RT) bridges disciplines to connect molecular, immunological and wildlife aspects of parasitic infections. The RT puts emphases on four groups of parasites: Plasmodium, Toxoplasma, Giardia and intestinal helminths. Co-infections are also covered by the RT as they represent the most common form of parasite infections in wildlife and domestic animal populations. Within the four types of parasites the following topics are addressed: (1) Experimental models: hypothesis testing, translation and limits. (2) Critical appraisal of experimental models. (3) Natural systems: Technological advances for investigations in natural parasite-host systems and studies in natural systems.-

    (4) The urgent need for better models and methods in natural parasite systems. Hence, the RT covers and illustrate by the means of four main parasitic infections the parasite-host system at the molecular, cellular and organismic level

    Abstract The molecular arms race between humans and Plasmodium falciparum in Africa resulted in selection of sickle-cell disease, which, on balance, protects heterozygote carriers against severe malaria. Band et al. discovered that parasites counter-adapt and can overcome disease resistance by identifying parasite genome signatures, termed P. falciparum sickle-associated (Pfsa) variants.

    Abstract Several species of Plasmodium cause a broad spectrum of human disease that range from nausea and fever to severe anemia, cerebral malaria, and multiorgan failure. In malaria-endemic countries, continuous exposure to Plasmodium sporozoite inoculations and subsequent blood infections elicit only partial and short-lived immunity, which gradually develops over many years of parasite exposure and multiple clinical episodes. The ambitious goal of malaria vaccinology over the past 70 years has been to develop an immunization strategy that mounts protection superior to naturally acquired immunity. Herein, three principal concepts in evidence-based malaria vaccine development are compared. Feasible leads are typically stand-alone subunit vaccine approaches that block Plasmodium parasite life cycle progression or parasite/host interactions, and they constitute the majority of candidates in preclinical research and early clinical testing. Integrated approaches incorporate malaria antigen(s) into licensed or emerging pediatric vaccine formulations. This strategy can complement the malaria control portfolio even if the antimalarial component is only partially effective and has led to the development of the only candidate vaccine to date, namely RTS,S-AS01. Experimental whole parasite vaccine approaches have been repeatedly shown to elicit sterile and lasting protection against identical parasite strains, but mass production, proof of broad protection against different parasite strains, and routes of vaccine delivery remain significant translational road blocks. Global access to an effective and affordable malaria vaccine will critically depend on innovative translational research that builds on a better molecular understanding of Plasmodium biology and host immunity.

    Abstract The liver is a major entry point and gatekeeper for invasive pathogens. However, high-resolution, spatiotemporal transcriptomic analysis of host-pathogen interactions has remained challenging. Afriat et al. have deconvoluted Plasmodium berghei liver-stage maturation at an unprecedented scale and discovered molecular signatures of heterogeneity during pre-erythrocytic development of malarial parasites.

    Abstract Eukaryotic pathogens with an intracellular parasitic lifestyle are shielded from extracellular threats during replication and growth. In addition to many nutrients, parasites scavenge host cell lipids to establish complex membrane structures inside their host cells. To counteract the disturbance of the host cell plasma membrane they have evolved strategies to regulate phospholipid asymmetry. In this review, the function and importance of lipid asymmetry in the interactions of intracellular protozoan parasites with the target and immune cells of the host are highlighted. The malaria parasite Plasmodium infects red blood cells and extensively refurbishes these terminally differentiated cells. Cholesterol depletion and an altered intracellular calcium ion homeostasis can lead to disruption in erythrocyte membrane asymmetry and increased exposure of phosphatidylserine (PS). Binding to the PS receptor on monocytes and macrophages results in phagocytosis and destruction of infected erythrocytes. Leishmania parasites display apoptotic mimicry by actively enhancing PS exposure on their surface to trigger increased infection of macrophages. In extracellular Toxoplasma gondii a P4-type ATPase/CDC50 co-chaperone pair functions as a flippase important for exocytosis of specialised secretory organelles. Identification and functional analysis of parasite lipid-translocating proteins, i.e. flippases, floppases, and scramblases, will be central for the recognition of the molecular mechanisms of parasite/host interactions. Ultimately, a better understanding of parasitic diseases, host immunity, and immune escape by parasites require more research on the dynamics of phospholipid bilayers of parasites and the infected host cell.

    Abstract Naturally acquired anti-Plasmodium falciparum immunity protects first and foremost against severe disease. Raj et al. have established a tantalizing path towards an anti-disease vaccine by identifying glutamic acid-rich protein (GARP) antibodies as signatures of protection against severe malaria in Tanzanian children and demonstrating efficacy in blood cultures and monkey trials.
