Alpha-synuclein is highly expressed in the central nervous system and plays an important role in pathogenesis of neurodegenerative disorders such as Parkinson's disease and Lewy body dementia. Previous studies have demonstrated the expression of α-synuclein in hematopoietic elements and peripheral blood mononuclear cells, although its roles in hematopoiesis and adaptive immunity are not studied. Using an α-synuclein knock out (KO) mouse model, we have recently shown that α-synuclein deficiency is associated with a mild defect in late stages of hematopoiesis. More importantly, we demonstrated a marked defect in B lymphocyte development and IgG, but not IgM production in these mice. …

Background and Objectives: Thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS) are characterized by microangiopathic hemolytic anemia and thrombocytopenia. Interestingly, markedly different survival rates have been reported despite increases in survivability. We studied TTP-HUS 30-day mortality and relapse rates of patients who received TPE at our institution and compared them to published data. Patients and Methods: Retrospective study analyzed 30-day mortality and relapse rates attributed to TTP-HUS from 01/01/2008 to 12/31/2012 and compared them to comparable literature reporting mortality and survival. Studies describing other etiologies for TPE and different mortality time interval were excluded. Results: Fifty-nine patients were analyzed …
