We studied the molecular composition of the neurotrophic/growth factor cocktail synthesized, stored and liberated by adrenomedullary chro

The human malaria parasite,Plasmodium falciparum, is currently being actively studied by molecular biologists. It is hoped that the use of recombinant DNA techniques in this area will give new insights into the biology of the organism and, at the same time, provide new approaches to diagnosis and vaccine development.Our own studies employ the blood stages of the parasite and cover three main areas: enzymes of importance in parasite metabolism; antigens of potential use in a subunit vaccine; and repetitive DNA as a probe able to distinguish genetically different isolates ofP. falciparumand as a species-specific diagnostic tool in human and mosquito infections.
