Effect of inherited red cell defects on growth of : An study.

Background & Objectives: High prevalence of certain polymorphic alleles of erythrocytes in malaria endemic area has been linked to the resistance provided by these alleles against parasitic infestations. Numerous studies undertaken to demonstrate this correlation have generated conflicting results. This study was undertaken to investigate the abilities of various polymorphic erythrocytes to support in vitro growth of Plasmodium falciparum parasites.

Plasmodium falciparum malaria skews globin gene expression balance in in-vitro haematopoietic stem cell culture system: Its implications in malaria associated anemia.

Understanding the pathophysiology and associated host parasite interactions of the malaria infection is the prerequisite for developing effective prevention and treatment strategies. The exact mechanism underlying malaria associated ineffective and dyserythropoiesis is not yet fully understood. Being an important protein, haemoglobin serves as the main amino acid reservoir available to the intra-erythrocytic plasmodium.

Comparison of protein expression pattern between the chloroquine-resistant RKL9 and chloroquine-sensitive MRC2 strains.

Objective: The objective of this study was to compare the protein expression patterns of extracellular and intracellular proteins separated by two-dimensional electrophoresis (2-DE) from the chloroquine-sensitive (CQS) MRC2 strain and chloroquine-resistant (CQR) RKL9 strain. Materials and Methods: Both the extracellular protein (ECP) and intracellular protein (ICP) were extracted and solubilized. The proteins were separated by 2-DE, first based on their charges using isoelectric focusing and then their sizes by electrophoresis.

Transcriptomic Analysis of Chloroquine-Sensitive and Chloroquine-Resistant Strains of Plasmodium falciparum: Toward Malaria Diagnostics and Therapeutics for Global Health.

Increasing drug resistance in Plasmodium falciparum is an important global health burden because it reverses the malarial control achieved so far. Hence, understanding the molecular mechanisms of drug resistance is the epicenter of the development agenda for novel diagnostic and therapeutic (drugs/vaccines) targets for malaria. In this study, we report global comparative transcriptome profiling (RNA-Seq) to characterize the difference in the transcriptome between 48-h intraerythrocytic stage of chloroquine-sensitive and chloroquine-resistant P.

Whole transcriptome expression analysis and comparison of two different strains of Plasmodium falciparum using RNA-Seq.

The emergence and distribution of drug resistance in malaria are serious public health concerns in tropical and subtropical regions of the world. However, the molecular mechanism of drug resistance remains unclear. In the present study, we performed a high-throughput RNA-Seq to identify and characterize the differentially expressed genes between the chloroquine (CQ) sensitive (3D7) and resistant (Dd2) strains of Plasmodium falciparum.

Correlation between 'H' blood group antigen and Plasmodium falciparum invasion.

The ABO blood group system is the most important blood group system in clinical practice. The relationship between Plasmodium falciparum and ABO blood groups has been studied for many years. This study was undertaken to investigate the abilities of different blood group erythrocytes to support in vitro growth of P.

Erythropoiesis in Malaria Infections and Factors Modifying the Erythropoietic Response.

Anemia is the primary clinical manifestation of malarial infections and is responsible for the substantial rate of morbidity. The pathophysiology discussed till now catalogued several causes for malarial anemia among which ineffective erythropoiesis being remarkable one occurs silently in the bone marrow. A systematic literature search was performed and summarized information on erythropoietic response upon malaria infection and the factors responsible for the same.

Tyrosine kinase inhibitors: New class of antimalarials on the horizon?

Development of the antimalarial drug resistant strains has currently become a major public health challenge. There is an urgent need to develop new antimalarial drugs. Tyrosine kinase inhibitors (TKIs) are receiving increasing attention as anticancer therapy.
