Researchers develop unique approach to calpain inhibition

Calpain, a calcium-regulated enzyme, is essential to a host of cellular processes, but can cause severe problems in its overactivated state. It has been implicated as a factor in muscular dystrophy, AIDS, Alzheimer's disease, multiple sclerosis, and cancer. As such, finding and exploiting calpain inhibitors is an important area of research.

New low-cost combined therapy shows promise against malaria

Malaria brings misery and death to millions in the developing world each year, and fighting it keeps medical researchers up at night because the mosquito-borne parasite Plasmodium falciparum, which causes the deadliest form of the disease, has developed resistance to every drug thrown at it. Resistance has cut short the useful life of nearly every therapy tried so far, experts say.

Ancient algae may hold key to treating malaria and related parasites

Researchers have discovered that parasites of the Apicomplexa taxon, such as Plasmodium falciparum and Toxoplasma gondii, reproduce within host cells using a structure that evolved from a flagellum.

Study finds important links between Pf malaria and endemic Burkitt Lymphoma

New research, presented this morning at the 54th Annual Meeting of the American Society of Hematology (ASH), has identified important associations between Plasmodium falciparum (Pf) malaria and endemic Burkitt Lymphoma (eBL) that may help researchers identify young children who are more susceptible to eBL.

Hebrew University researchers pave way for development of new approaches to cure malaria

More than a million people die each year of malaria caused by different strains of the Plasmodium parasite transmitted by the Anopheles mosquito. The medical world has yet to find an effective vaccine against the deadly parasite, which mainly affects pregnant women and children under the age of five. By figuring out how the most dangerous strain evades the watchful eye of the immune system, researchers from the Hebrew University of Jerusalem have now paved the way for the development of new approaches to cure this acute infection.

Interim results from RTS,S vaccine on-going phase III trial on malaria

According to the World Health Organization (WHO), more than 250 million clinical malaria cases are attributed to Plasmodium falciparum (Pf) annually, with over 1.1 million deaths in sub-Saharan Africa alone.

Combination of mosquito nets and deltamethrin does not lead to decline in malaria

Some develop resistance. Others alter their behaviour. Mosquitoes of the genus Anopheles, the vectors of malaria, always find a way to foil human attempts to protect themselves from this disease. Researchers from the IRD and their partners have revealed their great capacity for adaptation, which weakens the strategies to combatting their presence, recommended by the WHO.

Researchers identify new means to eradicate malaria infections

Researchers have identified a new means to eradicate malaria infections by rapidly killing the blood-borne Plasmodium parasites that cause the disease.

First demonstration of newly developed dual humanized FRGTM KO system against malaria

A novel human liver-chimeric mouse model developed at Oregon Health & Science University and Yecuris Corporation has made possible a research breakthrough at Seattle Biomedical Research Institute that will greatly accelerate studies of the most lethal forms of human malaria.

Scientists identify specific role of RESA protein in modulating blood circulation

When the parasite responsible for malaria infects human red blood cells, it launches a 48-hour remodeling of the host cells. During the first 24 hours of this cycle, a protein called RESA undertakes the first step of renovation: enhancing the stiffness of the cell membranes.

New book on malaria tells story of Plasmodium falciparum Genome Project

Few infectious diseases can rival malaria's ability to kill and cripple. Each year the disease causes hundreds of millions of people to be sickened and more than a million - mostly African children under the age of five - die.

Article describes novel technique to study interactions between HIV-1 and P. falciparum

The World Health Organization estimates that in 2011 there were 216 million cases of malaria and 34.2 million people living with HIV. These diseases particularly afflict sub-Saharan Africa, where large incidence of co-infection result in high mortality rates. Yet, in spite of this global pandemic, interactions between the parasite that causes malaria, Plasmodium falciparum, and HIV-1 are poorly understood.

NIH awards ADi Phase II SBIR grant to scan Plasmodium falciparum proteome for protective antigens

Antigen Discovery, Inc. today announced that it has received a Phase II Small Business Innovation and Research award from the National Institute of Allergy and Infectious Diseases of the National Institutes of Health. The three-year award, totaling approximately $ 2.5 million, is a continuation of a Phase I SBIR grant to scan the Plasmodium falciparum proteome for protective antigens.

BioDiem granted European patent for antimicrobial drug

Australian vaccine development company BioDiem Ltd (ASX: BDM) announced today the successful granting of a key European patent for its synthetic antimicrobial compound BDM-I. BDM-I is a novel compound active against a range of pathogenic micro-organisms including bacteria, fungi and protozoa. The patent provides protection around BDM-I as a treatment for vulvovaginitis, a general term for inflammation of the vulva or vagina.

Scientists decode stability blueprint of rhomboid enzyme

Johns Hopkins scientists have decoded for the first time the "stability blueprint" of an enzyme that resides in a cell's membrane, mapping which parts of the enzyme are important for its shape and function.

Malaria misdiagnosis: an interview with Dr Toby Leslie

Malaria is caused by a multi-staged parasite which is transmitted by the bite of infected female anopheles mosquitoes. It affects millions of people and kills more than 500,000 people throughout the world every year.

Malaria commonly misdiagnosed and mistreated in Afghanistan

Findings published in the BMJ suggest that malaria is being significantly misdiagnosed in Afghanistan, with many patients with fever alone being given antimalarial drugs and antibiotics despite having negative laboratory results for the disease.

BioDiem presents positive findings of their eye disease drug at international conference

Australian infectious disease therapy and vaccine development company BioDiem Ltd (ASX: BDM) today announced positive results from formal studies of its BDM-E eye disease drug, presented over 21 – 22 July at the International Society for Eye Research (ISER) meeting in Berlin, Germany. The ISER convenes leading researchers and clinicians in the area of eye disease.

Scientists identify inhibitors of key enzyme involved in survival of malaria parasite

An international team of scientists, led by researchers from the Department of Pediatrics at the University of California, San Diego School of Medicine, have identified the first reported inhibitors of a key enzyme involved in survival of the parasite responsible for malaria. Their findings, which may provide the basis for anti-malarial drug development, are currently published in the online version of the Journal of Medicinal Chemistry.
