    Lysosomal trafficking regulator Lyst links membrane trafficking to toll-like receptor-mediated inflammatory responses.
    J Exp Med 2017 Jan 23;214(1):227-244. Epub 2016 Nov 23.
    Institute of Clinical Chemistry, Inflammation Research Group, Hannover Medical School, 30625 Hannover, Germany
    Subcellular compartmentalization of receptor signaling is an emerging principle in innate immunity. However, the functional integration of receptor signaling pathways into membrane trafficking routes and its physiological relevance for immune responses is still largely unclear. In this study, using Lyst-mutant beige mice, we show that lysosomal trafficking regulator Lyst links endolysosomal organization to the selective control of toll-like receptor 3 (TLR3)- and TLR4-mediated proinflammatory responses.

    NK cell effector functions in a Chédiak-Higashi patient undergoing cord blood transplantation: Effects of in vitro treatment with IL-2.
    Immunol Lett 2016 Dec 2;180:46-53. Epub 2016 Nov 2.
    Department of Molecular Medicine, Istituto Pasteur-Fondazione Cenci Bolognetti, "Sapienza" University of Rome, Italy.
    NK cell cytotoxicity in Chédiak-Higashi syndrome (CHS) is strongly impaired as lytic granules are not released upon NK-target cell contact, contributing to several defects typical of this severe immunodeficiency. Correction of NK cell defects in CHS should improve the outcome of hematopoietic stem-cell transplantation, proposed as therapy. We investigated NK cell functions in a CHS patient before and after cord-blood transplantation, and the ability of in vitro IL-2 treatment to restore them. Read More

    Neutrophil functional disorder in childhood.
    Pril (Makedon Akad Nauk Umet Odd Med Nauki) 2015 ;36(1):183-90
    Department of immunology, University Clinic for Children`s Diseases, Medical Faculty, Skopje, R. Macedonia.
    Neutrophil functional disorders thought to be uncommon, yet important as a cause of morbidity and mortality in infants and children. During the first years of life, when the immune system is still not completely mature, when the viral infections are frequent and antibiotic overuse can damage and alter the immune response, the inadequate nutrition followed with iron deficient anemia and malnutrition can lead the child`s organism in state of immunodeficiency. Sometimes is difficult to distinguish at the beginning weather the cause of patient suffering from frequent infections is existing of primary immunodeficiency disorder or the cause of the immunodeficiency state is just from exogenous factors.

    Peripheral neuropathy and parkinsonism: a large clinical and pathogenic spectrum.
    J Peripher Nerv Syst 2014 Dec;19(4):333-42
    University of Bordeaux, Bordeaux, France; CNRS, Institut des Maladies Neurodégénératives, Bordeaux, France; Department of Pathology, Bordeaux University Hospital, Bordeaux, France.
    Peripheral neuropathy (PN) has been reported in idiopathic and hereditary forms of parkinsonism, but the pathogenic mechanisms are unclear and likely heterogeneous. Levodopa-induced vitamin B12 deficiency has been discussed as a causal factor of PN in idiopathic Parkinson's disease, but peripheral nervous system involvement might also be a consequence of the underlying neurodegenerative process. Occurrence of PN with parkinsonism has been associated with a panel of mitochondrial cytopathies, more frequently related to a nuclear gene defect and mainly polymerase gamma (POLG1) gene. Read More
