malaria/tyrosine

Microcrystalline Tyrosine (MCT®) is a widely used proprietary depot excipient in specific immunotherapy for allergy. In the current study we assessed the potential of MCT to serve as an adjuvant in the development of a vaccine against malaria. To this end, we formulated the circumsporozoite protein

Cerebral malaria induced by Plasmodium berghei ANKA infection is dependent on the sequestration of cytotoxic T cells within the brain and augmentation of the inflammatory response. Herein, we demonstrate that inhibition of protein tyrosine phosphatase (PTP) activity significantly attenuates T cell

The innate immune system uses inflammation to respond to infection of humans by various parasitic organisms and in some individuals can produce a hyperinflammatory response to infection by the human malaria parasites Plasmodium falciparum and vivax, leading to a more severe form of the

The levels of nuclear transcription factor-kappa B (NF-kappaB) subunits p65 and p50 and its associated kinase, inhibitory kappa B kinase (IKK) alpha and beta were monitored in cytosolic and nuclear fraction of mice cerebral cortex and cerebellum using an experimental model of fatal murine cerebral

Eukaryotic parasites of the genus Plasmodium cause malaria by invading and developing within host erythrocytes. Here, we demonstrate that PfShelph2, a gene product of Plasmodium falciparum that belongs to the Shewanella-like phosphatase (Shelph) subfamily, selectively hydrolyzes phosphotyrosine, as

Protein tyrosine kinases (PTKs) are believed to be implicated in the parasite growth, maturation and differentiation functions. Protein tyrosine kinase activity was found to be distributed in all the stages of P. falciparum parasite maturation. Membrane bound PTK activity was found to be increased

Over the last decade, several protein kinases inhibitors have reached the market for cancer chemotherapy. The kinomes of pathogens represent potentially attractive targets in infectious diseases. The functions of the majority of protein kinases of Plasmodium falciparum, the parasitic protist

A relatively high-affinity inhibitor of FIKK kinase from the malaria parasite Plasmodium vivax was identified by in vitro assay of recombinant kinase. The FIKK kinase family is unique to parasitic organisms of the Apicomplexan order and has been shown to be critical in malaria parasites. The

OBJECTIVE Recent work with the yeast model revealed that the antiprotozoal drug quinine competes with tryptophan for uptake via a common transport protein, causing cellular tryptophan starvation. In the present work, it was hypothesized that similar interactions may occur in malaria patients

Malaria is a devastating disease caused by a unicellular protozoan, Plasmodium, which affects 3.7 million people every year. Resistance of the parasite to classical treatments such as chloroquine requires the development of new drugs. To gain insight into the mechanisms that control Plasmodium cell

Proliferating Cell Nuclear Antigen (PCNA) undergoes several post-translational modifications including phosphorylation leading to its regulation in mammalian and yeast systems. Plasmodium falciparum possesses two PCNAs (PCNA1 & PCNA2) with an edge of PfPCNA1 over PfPCNA2 for DNA replication. Recent

1. Culex females are fed on C14-phenylalanine or C14-tyrosine in sugar solution. Autoradiographic studies on homogenated females 1 or 4 days after feeding, show that the labeled amino acids are metabolized on the first day and are not detectable on the fourth day. 2. After increase of the amino acid

Falcipain-2 (FP2) is an important hemoglobinase from the malaria parasite Plasmodium falciparum and a suitable target for the development of an antimalarial chemotherapy. Many reports have indicated that radical nitrogen species (RNS) including nitric oxide (NO) are inhibitors of P. falciparum
