Project description:Schistosoma japonicum is one of the remarkable platyhelminths that are endemic in the South Asian countries. The parasite is dioecious and can parasitize inside host blood stream for many years. Rapid reproduction by producing large number of eggs and count-react or active manipulating host anti-parasite responses are the strategies that benefit the long term parasitization of the parasite. Currently, Praziquantel is the only commercial drug that is effective against the worms but not the eggs of parasite in the host and no vaccine available to prevent human or animal schistosomiasis. Development of novel antiparasite reagents and immune-prevention measures rely on the deciphering of parasite biology. The decoding of the genomic sequence of the parasite has made it possible to dissect the biological functions of genes that govern the development of the parasite inside the hosts. In this study, the polyadenylated RNA from male and female S. japonicum was isolated and deep sequenced. By comparative analysis on the transcriptomic differences of the two sexes of the parasite, potential genes or gender-specific biological pathways can be targeted.

By comparative analysis on the transcriptomic differences of the two sexes of the parasite, potential genes or gender-specific biological pathways can be targeted. Messenger RNA from male and female S. japonicum parasite was selectively purified from total RNA using oligo-(dT) conjugated magnetic beads. Complementary DNA (cDNA) was synthesized guided by oligo-(dT) as a primer.

Project description:Parasite biology, by its very nature, cannot be understood without integrating it with that of the host, nor can the host response be adequately explained without considering the activity of the parasite. However, due to experimental limitations, molecular studies of parasite-host systems have been predominantly one-sided investigations focusing on either of the partners. Here we conduct a joint dual RNA-seq time course analysis of filarial parasite and host mosquito to better understand the parasite processes underlying development in, and interaction with, the host tissue from the establishment of infection to the emergence of infective-stage larva. Using the Brugia malayi-Aedes aegypti system, we report the parasite gene transcription dynamics, which exhibit a highly ordered developmental program consisting of a series of cyclical and state-transitioning temporal patterns. And, we contextualize these parasite data in relation to the concurrent dynamics of the host transcriptome. Comparative analyses using uninfected tissues and different host strains reveal the influence of parasite development on the host gene transcription as well as the influence of host environment on the parasite gene transcription. Furthermore, we critically evaluate the life-cycle transcriptome of B. malayi by comparing developmental stages in the mosquito relative to those in the mammalian host, providing insight into gene expression changes underpinning the mosquito-borne parasitic lifestyle of this heteroxenous parasite. Time-course mRNA profiles of filarial parasite Brugia malayi and host mosqutio Aedes aegypti were generated by deep sequencing using Illumina GAIIx.

Project description:Cerebral Malaria (CM), the deadliest complication of Plasmodium infection, is a complex and unpredictable disease. Currently, our understanding of the factors that trigger progression of malaria to CM is limited. Here, by infecting experimental CM (ECM) resistant (Balb/c) and ECM susceptible (C57BL/6) mice with ECM causing (ANKA) and non-ECM causing (NK65) Plasmodium berghei (Pb) parasite strains, we revealed that in resistant host, infection by ECM causing parasite develops similar to infection by non-ECM causing parasite in susceptible host in terms of parasite growth in host, disease course and host immune response against parasite. Our comparative gene expression analysis revealed that in Balb/c host, gene expression of Pb ANKA parasite is remarkably different from, the gene expression of Pb ANKA in C57BL/6 but similar to the gene expression of non-ECM causing Pb NK65 in C57BL/6. Thus, host has a critical influence on parasite behavior which ultimately determines the course of malaria disease.

Project description:Liver stage of malaria parasite exports SLTRiP and PB268 to the cytosol of parasite infected host cell. To know the host genes perturbed by WT-PBANKA, SLTRiP-KO and PB268-KO parasite growth, we did transcriptomic sequencing of infected host cells. We did mRNA sequencing of four samples for comparative analysis of WT and PB-knockout parasites infected host cells at 22 hours of post sporozoites infection.

Project description:Intracellular pathogens develop elaborate mechanisms to survive within the hostile environments of host cells. Theileria parasites infect bovine leukocytes and cause devastating diseases in cattle in developing countries. Theileria spp. have evolved sophisticated strategies to hijack host leukocytes, inducing proliferative and invasive phenotypes characteristic of cell transformation. Intracellular Theileria parasites secrete proteins into the host cell and recruit host proteins to induce oncogenic signaling for parasite survival. It is unknown how Theileria parasites evade host cell defense mechanisms, such as autophagy, to survive within host cells. Here, we show that Theileria annulata parasites sequester the host eIF5A protein to their surface to escape elimination by autophagic processes. We identified a small-molecule compound that reduces parasite load by inducing autophagic flux in host leukocytes, thereby uncoupling Theileria parasite survival from host cell survival. We took a chemical genetics approach to show that this compound induced host autophagy mechanisms and the formation of autophagic structures via AMPK activation and the release of the host protein eIF5A which is sequestered at the parasite surface. The sequestration of host eIF5A to the parasite surface offers a strategy to escape elimination by autophagic mechanisms. These results show how intracellular pathogens can avoid host defense mechanisms and identify a new anti-Theileria drug that induces autophagy to target parasite removal.
