    The biology of malarial parasite in the mosquito: a review

    No full text
    The purpose of this review is to summarize the biology of Plasmodium in the mosquito including recent data to contribute to better understanding of the developmental interaction between mosquito and malarial parasite. The entire sporogonic cycle is discussed taking into consideration different parasite/vector interactions and factors affecting parasite development to the mosquito

    Mitochondrial Permeability Transition in the CNS - Composition, Regulation, and Pathophysiological Relevance

    No full text
    Mitochondrial permeability transition (MPT) is induced in isolated brain mitochondria by calcium and oxidants and is inhibited by adenine nucleotides. When induced, MPT is associated with equilibration of solutes of <1500 Da across the inner mitochondrial membrane. A persistent induction of MPT depolarizes the inner membrane and causes cessation of ATP synthesis, swelling of the matrix, and bursting of the mitochondrial membranes. The rupture of the membranes releases calcium stored in the mitochondrial matrix and apoptogenic factors from the intermembrane space, leading to cell death. MPT has been implicated in acute brain injury and neurodegenerative disease since inhibitors of MPT such as cyclosporin A (CsA) are brain protective. Whether MPT has a physiological role is unclear, but MPT may be important in calcium homeostasis under conditions of excessive neuronal activity
