  2. 1. Signaling determinants in Trojan horse-mediated dissemination of Toxoplasma gondii

    Author : Einar B. Ólafsson; Antonio Barragan; Eva Frickel; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apicomplexa; leukocyte motility; dendritic cell; amoeboid migration; host-parasite interactions; podosome; integrin; ITGB1; ECM; MAT; TIMP; MMP; MAPK; Erk; RTK; HGFR; Ras; calcium; VDCC; VGCC; calmodulin; CaMkII; CD63; FAK; SRC; Pi3k; hypermigration; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Toxoplasma gondii is an obligate intracellular parasite that infects all warm-blooded vertebrates including one third of the global human population. While infection is typically asymptomatic in healthy human hosts, reactivated and acute infection in immunosuppressed or immunecompromised individuals can lead to lethal toxoplasmic encephalitis After ingestion, the parasite crosses the intestinal epithelium and rapidly achieves systemic dissemination, ultimately establishing chronic infection in the brain.

  4. 2. Phosphoinositides control insulin secretion through multiple routes

    Author : Phuoc My Nguyen; Christina Bark; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phosphoinositides; PI 4 P; PI 4; 5 P2; Ca2 ; optogenetics; VDCC; Sac2; OSBP; OSW-1; cholesterol; membrane contact sites;

    Abstract : Glucose-stimulated insulin secretion from pancreatic beta cells is the sequence of events that starts with glucose uptake and ends with the fusion of insulin granules with the plasma membrane through Ca2+-triggered exocytosis. Phosphoinositides are minor components of all cellular membranes, yet play fundamental roles as regulators of many cellular processes. READ MORE

  5. 3. Virus mediated induction of antibody independent cytotoxicity (VDCC) and enhancement of antibody dependent cytotoxicity (ADCC) in human lymphocytes in vitro

    Author : Abdul-Razzak Alsheikhly; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Addition in vitro of small amounts of paramyxoviruses (Mumps or Sendai) to lymphocytes from healthy human donors induces a strong and non-selective cytotoxicity against a variety of target cells (VDCC, virus dependent cellular cytotoxicity). VDCC-like reactions are believed to play a role in vivo in the defense against virus infection and/or the causation of the tissue lesions associated with virus disease. READ MORE

  6. 4. Apoptosis And Excitotoxicity In The Death of Cultured And Grafted Dopaminergic Neurones

    Author : Gabriele Schierle; Institutionen för experimentell medicinsk vetenskap; []

    Abstract : Over the past two decades, grafting of embryonic nigral tissue has developed into a feasible therapeutic strategy for Parkinson's disease (PD). It has become apparent that the degree of restoration of dopaminergic neurotransmission by the transplanted cells is highly correlated to the symptomatic relief. READ MORE
