To rapidly respond to invading microorganisms, humans call on their innate immune system. This occurs by microbe-detecting receptors, such as CD14, that activate immune cells to eliminate the pathogens. Here, we link the lipopolysaccharide receptor CD14 with Alzheimer's disease, a severe neurodegenerative disease resulting in dementia. We demonstrate that(More)
In Alzheimer's disease (AD), Parkinson's disease (PD), dementia with Lewy bodies (DLB) and amyotrophic lateral sclerosis (ALS), neuroinflammatory responses are considered to contribute to neuronal injury. Recently, the innate immune receptors, toll-like receptors (TLRs) and the LPS receptor (CD14) have been related to neurodegeneration. In this study, we(More)
The amyloid beta peptide 42 (Abeta(42)) plays a key role in neurotoxicity in Alzheimer's disease. Mononuclear phagocytes, i.e. microglia, have the potential to clear Abeta by phagocytosis. Recently, the lipopolysaccharide (LPS) receptor CD14 was shown to mediate phagocytosis of bacterial components and furthermore to contribute to neuroinflammation in(More)
BACKGROUND Only 2-5% of patients who have a stroke receive thrombolytic treatment, mainly because of delay in reaching the hospital. We aimed to assess the efficacy of a new approach of diagnosis and treatment starting at the emergency site, rather than after hospital arrival, in reducing delay in stroke therapy. METHODS We did a randomised single-centre(More)
BACKGROUND Early treatment with rt-PA is critical for favorable outcome of acute stroke. However, only a very small proportion of stroke patients receive this treatment, as most arrive at hospital too late to be eligible for rt-PA therapy. METHODS AND FINDINGS We developed a "Mobile Stroke Unit", consisting of an ambulance equipped with computed(More)
Multiple sclerosis (MS) is pathologically characterized by inflammatory demyelination and neuronal injury. Although phagocytosis of myelin debris by microglia and macrophages in acute MS lesions is well documented, its pathophysiological significance is unclear. Using real-time quantitative PCR, flow cytometry, ELISA, and reactive oxygen species (ROS)(More)
Alzheimer's disease (AD) is a neurodegenerative disease characterized by deposits of amyloid β peptide (Aβ) and microglia-driven inflammatory activation. Tenascin-C (tnc) is an extracellular matrix protein that is upregulated in inflammation and induces further inflammatory responses. We hypothesized that tnc contributes to the inflammatory pathology in AD.(More)
Currently, stroke laboratory examinations are usually performed in the centralized hospital laboratory, but often planned thrombolysis is given before all results are available, to minimize delay. In this study, we examined the feasibility of gaining valuable time by transferring the complete stroke laboratory workup required by stroke guidelines to a(More)
Thrombolysis with alteplase administered within a narrow therapeutic window provides an effective therapy for acute ischaemic stroke. However, mainly because of prehospital delay, patients often arrive too late for treatment, and no more than 1-8% of patients with stroke obtain this treatment. We recommend that all links in the prehospital stroke rescue(More)
Alzheimer's disease is characterized by extracellular deposits of amyloid β peptide in the brain. Increasing evidence suggests that amyloid β peptide injures neurons both directly and indirectly by triggering neurotoxic innate immune responses. Myeloid differentiation factor 88 is the key signalling molecule downstream to most innate immune receptors(More)
