Reactive oxygen species (ROS) are formed by myeloid cells as a defense strategy against microorganisms. ROS however also trigger poly(ADP-ribose) polymerase 1- (PARP-1) dependent cell death (parthanatos) in adjacent lymphocytes, which has been forwarded as a mechanism of immune escape in several forms of cancer. The present study assessed the role of(More)
OBJECTIVES To describe a population-based material of patients with recurrent Guillain-Barré syndrome (RGBS), examine the long time course, and search for factors predisposing to recurrence. MATERIALS AND METHODS We performed a follow-up study of the neurology and neurophysiology and a systematic study of the acute microbial serology of patients with(More)
BACKGROUND The formylpeptide receptor family members FPR and FPRL1, expressed in myeloid phagocytes, belong to the G-protein coupled seven transmembrane receptor family (GPCRs). They share a high degree of sequence similarity, particularly in the cytoplasmic domains involved in intracellular signaling. The established model of cell activation through GPCRs(More)
This study investigated the relationship between the formation of NADPH oxidase-dependent oxygen radicals in peripheral blood leukocytes ('respiratory burst') and disease severity in patients with multiple sclerosis (MS). Oxygen radical production was induced by formyl-Met-Leu-Phe (fMLF), Trp-Lys-Tyr-Met-Val-Met-NH2 (WKYMVM) or phorbol myristate acetate(More)
The NADPH oxidase-dependent formation of reactive oxygen species ("oxygen radicals") by phagocytic cells constitutes an important part of the innate immune defence against microorganisms. Recent studies in animal models imply that a deficient function of the NADPH oxidase may be linked to the development of autoimmunity, but a link between oxygen radical(More)
BACKGROUND The recurrent Guillain-Barré syndrome (RGBS) is characterized by at least two GBS episodes with intervening remission. In a previous study of monophasic GBS, we reported that the magnitude of oxygen radical production ("respiratory burst") in peripheral blood leukocytes was inversely correlated to disease severity. The present study sought to(More)
