Abstract
INTRODUCTION Systemic lupus erythematosus (SLE) is complex autoimmune disease with heterogenous manifestations, unpredictable disease course and response to treatment. One of the critical needs in SLE management is the identification of reliable biomarkers that can aid in early diagnosis, accurate monitoring of disease activity, and assessment of treatment response. AREAS COVERED In the current review, we focus on the commonly affected organs (skin, kidney, and nervous system) in SLE to summarize the emerging biomarkers that show promise in disease diagnosis, monitoring and treatment response assessment. The subtitles within each organ domain were determined based on the most relevant and promising biomarkers for that specific organ damage. EXPERT OPINION Biomarkers have the potential to significantly benefit the management of SLE by aiding in diagnosis, disease activity monitoring, prognosis, and treatment response assessment. However, despite decades of research, none has been validated and implemented for routine clinical use. Novel biomarkers could lead to the development of precision medicine for SLE, guide personalized treatment, and improve patient outcomes. Challenges in biomarker research in SLE include defining clear and clinically relevant questions, accounting for the heterogeneity of SLE, and confirming initial findings in larger, multi-center, multi-ethnic, independent cohorts that reflect real-world clinical scenarios.

Abstract
Systemic lupus erythematosus is a complex immunological disease where both environmental factors and genetic predisposition lead to the dysregulation of important immune mechanisms. Eventually, the combination of these factors leads to the production of self-reactive antibodies that can target any organ or tissue of the human body. Autoantibodies can form immune complexes responsible for both the organ damage and the most severe complications. Involvement of the central nervous system defines a subcategory of the disease, generally known with the denomination of neuropsychiatric systemic lupus erythematosus. Neuropsychiatric symptoms can range from relatively mild manifestations, such as headache, to more severe complications, such as psychosis. The evaluation of the presence of the autoantibodies in the serum of these patients is the most helpful diagnostic tool for the assessment of the disease. The scientific progresses achieved in the last decades helped researchers and physicians to discover some of autoepitopes targeted by the autoantibodies, although the majority of them have not been identified yet. Additionally, the central nervous system is full of epitopes that cannot be found elsewhere in the human body, for this reason, autoantibodies that selectively target these epitopes might be used for the differential diagnosis between patients with and without the neuropsychiatric symptoms. In this review, the most relevant data is reported with regard to mechanisms implicated in the production of autoantibodies and the most important autoantibodies found among patients with systemic lupus erythematosus with and without the neuropsychiatric manifestations.

Abstract
INTRODUCTION The aim of this narrative review is to provide an overview of the literature on the possible immunologic pathophysiology of psychiatric manifestations of neuropsychiatric systemic lupus erythematosus (NPSLE). METHODS A systematic search on PubMed was conducted. English studies with full text availability that investigated the correlation between blood-brain barrier (BBB) dysfunction, intrathecal synthesis of antibodies, antibodies, cytokines, chemokines, metalloproteinases, complement and psychiatric NPSLE manifestations in adults were included. RESULTS Both transient BBB-dysfunction with consequent access of antibodies to the cerebrospinal fluid (CSF) and intrathecal synthesis of antibodies could occur in psychiatric NPSLE. Anti-phospholipid antibodies, anti-NMDA antibodies and anti-ribosomal protein p antibodies seem to mediate concentration dependent neuronal dysfunction. Interferon-α may induce microglial engulfment of neurons, direct neuronal damage and production of cytokines and chemokines in psychiatric NPSLE. Several cytokines, chemokines and matrix metalloproteinase-9 may contribute to the pathophysiology of psychiatric NPSLE by attracting and activating Th1-cells and B-cells. DISCUSSION This potential pathophysiology may help understand NPSLE and may have implications for the diagnostic management and therapy of psychiatric NPSLE. However, the presented pathophysiological model is based on correlations between potential immunologic etiologies and psychiatric NPSLE that remain questionable. More research on this topic is necessary to further elucidate the pathophysiology of NPSLE.

Abstract
Is systemic lupus erythematosus (SLE) is occurring more frequently now than in decades past? Despite improvements in the identification of patients with SLE, the development of new classification criteria, and the recognition of several biomarkers used alone or in combination, the diagnosis of SLE is still a challenge for clinicians, in particular early in the course of the disease, which makes the recognition of secular trends difficult to ascertain. Lacking a uniform definition of preclinical lupus or incomplete lupus, it is difficult to predict accurately which patients would go on to develop SLE. We will briefly review the classification criteria, early or preclinical SLE, the epidemiology of SLE, antinuclear antibodies-negative SLE, and biomarkers of the disease.

Abstract
Objective The aim was to investigate the association between autoantibodies (autoAbs) and neuropsychiatric (NP) involvement in patients with SLE and to evaluate whether any autoAb or a combination of these autoAbs could indicate the underlying pathogenic process. Methods Using a multiplexed protein array for 94 antigens, we compared the serum autoAb profiles of 69 NPSLE patients, 203 SLE patients without NP involvement (non-NPSLE) and 51 healthy controls. Furthermore, we compared the profiles of NPSLE patients with clinical inflammatory (n = 38) and ischaemic (n = 31) NP involvement. Results In total, 75 IgG and 47 IgM autoAbs were associated with SLE patients in comparison with healthy controls. Comparing NPSLE with non-NPSLE and healthy control sera, 9 IgG (amyloid, cardiolipin, glycoprotein 2, glycoprotein 210, heparin, heparan sulphate, histone H2A, prothrombin protein and vimentin) and 12 IgM (amyloid, cardiolipin, centromere protein A, collagen II, histones H2A and H2B, heparan sulphate, heparin, mitochondrial 2, nuclear Mi-2, nucleoporin 62 and vimentin) autoAbs were present at significantly different levels in NPSLE. The combination of IgG autoAbs against heparan sulphate, histone H2B and vimentin could differentiate NPSLE from non-NPSLE (area under the curve 0.845, 99.97% CI: 0.756, 0.933; P < 0.0001). Compared with non-NPSLE, four IgG and seven IgM autoAbs were significantly associated with inflammatory NPSLE. In ischaemic NPSLE, three IgG and three IgM autoAbs were significantly different from non-NPSLE patients. Conclusion In our cohort, the presence of high levels of anti-heparan sulphate and anti-histone H2B combined with low levels of anti-vimentin IgG autoAbs is highly suggestive of NPSLE. These results need to be validated in external cohorts.

Autoantibody profiling on human proteome microarray for biomarker discovery in cerebrospinal fluid and sera of neuropsychiatric lupus. PLoS One 2015; 10:e0126643.

Abstract
Autoantibodies in cerebrospinal fluid (CSF) from patients with neuropsychiatric systemic lupus erythematosus (NPSLE) may be potential biomarkers for prediction, diagnosis, or prognosis of NPSLE. We used a human proteome microarray with~17,000 unique full-length human proteins to investigate autoantibodies associated with NPSLE. Twenty-nine CSF specimens from 12 NPSLE, 7 non-NPSLE, and 10 control (non-systemic lupus erythematosus)patients were screened for NPSLE-associated autoantibodies with proteome microarrays. A focused autoantigen microarray of candidate NPSLE autoantigens was applied to profile a larger cohort of CSF with patient-matched sera. We identified 137 autoantigens associated with NPSLE. Ingenuity Pathway Analysis revealed that these autoantigens were enriched for functions involved in neurological diseases (score = 43).Anti-proliferating cell nuclear antigen (PCNA) was found in the CSF of NPSLE and non-NPSLE patients. The positive rates of 4 autoantibodies in CSF specimens were significantly different between the SLE (i.e., NPSLE and non-NPSLE) and control groups: anti-ribosomal protein RPLP0, anti-RPLP1, anti-RPLP2, and anti-TROVE2 (also known as anti-Ro/SS-A). The positive rate for anti-SS-A associated with NPSLE was higher than that for non-NPSLE (31.11% cf. 10.71%; P = 0.045).Further analysis showed that anti-SS-A in CSF specimens was related to neuropsychiatric syndromes of the central nervous system in SLE (P = 0.009). Analysis with Spearman’s rank correlation coefficient indicated that the titers of anti-RPLP2 and anti-SS-A in paired CSF and serum specimens significantly correlated. Human proteome microarrays offer a powerful platform to discover novel autoantibodies in CSF samples. Anti-SS-A autoantibodies may be potential CSF markers for NPSLE.

Abstract
A 39-year-old woman suddenly developed numbness of the left arm following mild weakness of the left upper and lower extremities, blindness in the left visual field, and difficulty finding words. Her symptoms lasted for two hours with no deficit remaining. Six months after the first episode, the first of several more occurred. Two of the episodes were followed by nausea and a non-pulsative headache around the left temporo-parietal regions and the orbit. She had also been suffering recurrent skin eruptions for the previous two years. There was no family history of migraine. Her neurological symptoms fulfilled the criteria of sporadic hemiplegic migraine (SHM). Biopsy of skin eruption revealed lymphocytic infiltration and liquefied degeneration of basal lamina. These findings were compatible with systemic lupus erythematosus (SLE). There were no lesions evident on brain MR. We diagnosed SLE and after administration of aspirin (100 mg/day) and lomerizine hydrochloride (10 mg/day), her neurological symptom completely disappeared. SHM-like headache in patients with SLE is extremely rare. Although an autoimmune or thrombotic mechanism has been suggested for neurological symptoms in SLE, further studies are needed to elucidate the mechanism. We propose that SLE should be considered as one of the differential diagnoses of SHM.

Abstract
Neuropsychiatric (NP) manifestations and brain pathology are poorly understood and potentially fatal concomitants of systemic lupus erythematosus (SLE). For many years, autoantibodies to brain tissue (i.e., brain-reactive antibodies, BRA) were proposed as a key factor in pathogenesis of CNS manifestations. Recent evidence suggests that intrathecal BRA, rather than serum autoantibodies, are a better predictor of disturbed brain morphology and function. We presently test this hypothesis by examining the relationship among BRA in cerebrospinal fluid (CSF), behavioral deficits, and brain pathology in a well-established animal model of CNS lupus. We showed earlier that significant diversity in disease manifestations within genetically homogenous MRL-lpr mice allows for constructive and informative correlational analysis. Therefore, levels of CSF antibodies were presently correlated with behavioral, neuropathological and immune measures in a cohort of diseased MRL-lpr males (N=40). ELISA, Western Blotting, standardized behavioral battery, digital planimetry, HE staining, and immunohistochemistry were employed in overall data collection. The IgG antibodies from CSF were binding to different regions of brain parenchyma, with dentate gyrus, amygdale, and subventricular zones showing enhanced immunoreactivity. High levels of CSF antibodies correlated with increased immobility in the forced-swim test and density of HE(+) cells in the paraventricular nucleus. Peripheral measures of autoimmunity were associated with other deficits in behavior and neuropathology. This correlation pattern suggests that etiology of brain damage in lupus-prone mice is multifactorial. Intrathecal BRA may be important in altering motivated responses and activity of major neuroendocrine axes at the onset of SLE-like disease.

Abstract
Oxidation of cerebrospinal fluid (CSF) causes differential unmasking of autoantibodies in control CSF vs. that obtained from postmortem CSF samples from autopsy confirmed Alzheimer's disease (AD) cases. This study demonstrates that normal CSF from both living patients and from non-demented autopsy cases contains redox-reactive autoantibodies with specificities that include antiphospholipid antibodies (aPL). In contrast, CSF from autopsy confirmed AD subjects contained little or no redox-reactive aPL autoantibodies. Tests using an in vitro rat synaptosome model showed that the oxidized CSF autoantibodies from a normal individual can cause ERK1/2 phosphorylation at a level consistent with reports of pathogenic changes found in brain tissues from AD patients. The decrease or absence of redox-reactive antibodies in CSF from Alzheimer's patients suggests that these antibodies may have been previously unmasked by the oxidative conditions that exist in the CNS in AD patients. These unmasked autoantibodies could then bind to neuronal tissues and possibly participate in the initial cascade leading to the dementia in Alzheimer's. To our knowledge, this is the first description of resident autoantibodies with the potential to cause brain cell damage documented in CSF without a breech in the blood-brain barrier. The untimely and inappropriate physiological unmasking of these redox-reactive autoantibodies in AD patients CSF may represent a valuable biomarker for diagnosis and progression of this and perhaps other neurodegenerative diseases which also have oxidative stress components. These novel autoantibody observations may stimulate thoughts about additional therapeutic approaches and warrant similar studies for other neurodegenerative diseases.

Abstract
In the course of Systemic Lupus Erythematosus (SLE), a variety of neuropsychiatric disturbances is reported with a prevalence ranging from 17% to 75%. The diagnosis of these syndromes is difficult and requires a careful psychiatric evaluation. Distinct autoantibodies detectable in serum or cerebrospinal fluid of patients with SLE are associated with the presence of neuropsychiatric disorders. These autoantibodies may have a pathogenic relevance in neuropsychiatric SLE or they may be merely an epiphenomenon. This review describes the various autoantibodies reported to be associated with neuropsychiatric manifestations in SLE and discusses their possible role.

Abstract
Neuropsychiatric manifestations are commonly observed in systemic lupus erythematosus (SLE) patients; however, cerebellar involvement has rarely been reported. In the presence of acute cerebellar ataxia, etiologies related (focal edema and ischemia) and not related (infections, malignancy and paraneoplastic syndromes) to lupus have to be considered and they imply different treatment strategies. We report the clinical and radiological features of 3 SLE patients who presented with acute cerebellar ataxia. A review of the literature was performed by documenting cases of cerebellar ataxia in SLE and the importance of neuroimaging in the evaluation of these patients.

Abstract
More than 50 different neurological pathologies have a confirmed or suspected autoimmune etiology affecting an estimated number of 75 million people worldwide. Autoantibodies are a useful diagnostic marker for most autoimmune diseases even though their pathological role is not evident, and several tests for their detection are commercially available. However, for autoimmune diseases involving the nervous system, lack of clear information on the identity of antineural antibody targets and the presence of many rare diseases have hampered the development of specific diagnostic assays. This review focuses on the actual knowledge on confirmed and suspected autoimmune diseases that target the CNS and the diagnostic relevance of corresponding antineural autoantibodies.

Abstract
Antiphospholipid antibodies (aPL) have been reported in the cerebrospinal fluids (CSF) of neurology patients but no CSF studies with psychiatric patients exist. We tested serum from 100 hospitalized psychotic patients having hallucinations and/or delusions for aPL. Patients with positive serum aPL findings were asked to submit CSF for aPL testing. Five CSF samples had aPL specificities not found in the patient's serum suggesting the possibility of intrathecal synthesis. Specificity and isotype discordance between CSF and blood aPL in these psychiatric patients implicates a central nervous system independent autoimmune process that may have an underlying association with the pathophysiology of their diseases.

Abstract
OBJECTIVE We sought (1) to identify and (2) to define the association of all reported antibodies (Abs) with neuropsychiatric lupus (NPSLE), (3) to search for possible mechanisms that are involved in NPSLE, and (4) to determine whether we can recognize a panel of Abs associated with specific neuropsychiatric (NP) manifestations. METHODS A MEDLINE search (1975 to 2005) was performed utilizing the following terms: neuropsychiatric lupus, antiphospholipid syndrome, or central nervous system systemic lupus erythematosus matched with the term antibodies. RESULTS Twenty Abs (11 brain-specific and 9 systemic) were described in NPSLE patients. These include Abs that target brain-specific antigens (neuronal, ganglioside, synaptosomes, glia, methyl-d-aspartate receptors, lymphocytotoxic) and systemic antigens (nuclear, cytoplasmic, phospholipid, endothelial cells). Cognitive impairment, psychosis, and depression were associated with many Abs. Elevated titers of anticardiolipin Abs (aCL) were reported most often and found in patients with cognitive impairment, psychosis, depression, seizures, chorea, and migraine. No specificity was encountered among brain-specific or systemic Abs for any single NP manifestation. No studies evaluated a specific NP manifestation with the full panel of 20 Abs. A panel of brain-specific and systemic Abs may be helpful in establishing the diagnosis of NPSLE. Postulated mechanisms in experimental models included vascular occlusion and injury by pathogenic Abs in a disrupted blood brain barrier. CONCLUSIONS NPSLE is associated with brain-specific and systemic Abs. Cognitive impairment, psychosis, and depression were associated with many Abs, including aCL Abs. Possible mechanisms include vascular occlusion and injury by pathogenic Abs in a disrupted blood brain barrier.

Abstract
The evidence supporting a causal relationship between antiphospholipid (aPL) antibodies and cognitive dysfunction is very limited despite a general impression that one exists. Patients with aPL antibodies may complain of cognitive difficulties in their everyday lives, forcing the clinician to examine this issue. As with other non-thrombotic antiphospholipid syndrome (APS) manifestations, cognitive dysfunction in this population should be approached as a diagnosis of exclusion. The complexity in diagnosing and treating various manifestations of rheumatic disease holds true for identifying and addressing cognitive decline in these patients.

Abstract
Brain atrophy, neurologic and psychiatric (NP) manifestations are common complications in the systemic autoimmune disease, lupus erythematosus (SLE). Here we show that the cerebrospinal fluid (CSF) from autoimmune MRL-lpr mice and a deceased NP-SLE patient reduce the viability of brain cells which proliferate in vitro. This detrimental effect was accompanied by periventricular neurodegeneration in the brains of autoimmune mice and profound in vivo neurotoxicity when their CSF was administered to the CNS of a rat. Multiple ionic responses with microfluorometry and protein peaks on electropherograms suggest more than one mechanism of cellular demise. Similar to the CSF from diseased MRL-lpr mice, the CSF from a deceased SLE patient with a history of psychosis, memory impairment, and seizures, reduced viability of the C17.2 neural stem cell line. Proposed mechanisms of cytotoxicity involve binding of intrathecally synthesized IgG autoantibodies to target(s) common to different mammalian species and neuronal populations. More importantly, these results indicate that the viability of proliferative neural cells can be compromised in systemic autoimmune disease. Antibody-mediated lesions of germinal layers may impair the regenerative capacity of the brain in NP-SLE and possibly, brain development and function in some forms of CNS disorders in which autoimmune phenomena have been documented.

Abstract
OBJECTIVE To analyse the available data regarding the presentation of psychosis in diseases of central nervous system (CNS) white matter. METHOD The available neurological and psychiatric literature on developmental, neoplastic, infective, immunological and other white matter diseases was reviewed. RESULTS A number of diseases of the white matter can present as schizophrenia-like psychoses, including leukodystrophies, neoplasms, velocardiofacial syndrome, callosal anomalies and inflammatory diseases. CONCLUSIONS Production of psychotic symptoms may result from functional asynchrony of interdependent regions, due to alterations in critical circuits as a result of pathology. The nature, location and timing of white matter pathology seem to be the key factors in the development of psychosis, especially during the critical adolescent period of association area myelination. Diseases that disrupt the normal formation of myelin appear to cause psychosis at higher rates than those that disrupt mature myelinated structures. Diffuse rather than discrete lesions, in particular those affecting frontotemporal zones, are also more strongly associated with schizophrenia-like psychosis. These illnesses point to the central role that white matter plays in maintaining CNS connectivity and to how pathology of the white matter may contribute to the neurobiology of psychosis.

Abstract
Spontaneous development of lupus-like disease is accompanied by impaired dopamine catabolism and degenerating axon terminals in the mesencephalon of MRL-lpr mice. We presently examine the hypothesis that systemic autoimmunity affects the central dopaminergic system in behaviorally impaired animals. The functional damage of the nigrostriatal pathway was assessed from rotational behavior after a single injection of the D1/D2-receptor agonist apomorphine. Neurodegeneration in the midbrain was estimated by Fluoro Jade B (FJB) staining. The causal role of autoimmunity was tested by comparing asymptomatic and diseased MRL-lpr mice, and by employing the immunosuppressive drug cyclophosphamide. Damage of dopaminergic neurons was assessed by tyrosine-hydroxylase (TH) staining of the midbrain. Apomorphine induced significant asymmetry in limb use, which lead to increased circling in the diseased MRL-lpr group. While FJB-positive somas were not seen in the striatum, increased staining in the substantia nigra (SN) and ventral tegmental area (VTA) were detected in behaviorally impaired MRL-lpr mice, but not in age-matched controls. Reduced brain mass and increased levels of TNF-alpha in their cerebrospinal fluid (CSF) suggested cerebral atrophy and inflammation. In addition, CSF was neurotoxic to a dopaminergic progenitor cell line. Immunosuppression attenuated CSF cytotoxicity, TNF-alpha levels, and midbrain neurodegeneration. Supportive of the notion that dying neurons were dopaminergic, the SN of autoimmune mice showed approximately a 35% reduction in the number of TH-positive cells. A three-fold increase in serum brain-reactive antibodies accompanied this loss. Although the source of toxic mediator(s) remains unknown, present results are consistent with the hypothesis that autoimmunity-induced destruction of mesonigral and mesolimbic dopaminergic pathways contributes to the etiology of aberrant behavior in an animal model of neuropsychiatric lupus.

Abstract
Dementia is a very rare neurological manifestation of systemic lupus erythematosus (SLE) and has a deep link with antiphospholipid antibodies (APL) and cerebral infarction in its development. However, nonvascular dementia irrelevant to APL or cerebral infarction has not been reported in patients with SLE until now. We describe a case of reversible dementia in an SLE patient without APL or cerebral infarction which was successfully treated with corticosteroid and cyclophosphamide. There are two significant points in this case. One is that humoral factors other than APL might be involved in the development of dementia. Secondly, reversible dementia without APL or cerebral infarction may respond more favorably to immunosuppressive therapy.

Abstract
Antiphospholipid antibody syndrome (APS) may present with neurological syndromes. Cerebrovascular disease, chorea/ballismus, epileptic seizures, headache, cognitive impairment, transverse myelopathy, Devic's syndrome and multiple sclerosis-like presentations feature among others. Cerebrovascular disease is one of the most common presenting symptoms of APS, second only to deep vein thrombosis, and accounts for half of neurological manifestations in patients with APS; accelerated atherogenesis and cardioembolism are the most likely mechanisms implicated. Though infrequent, chorea is consistently associated with APS; the pathogenetic role of antiphospholipid antibodies (APLab) in this case might be routed through cerebrovascular disease in some cases and through purely immunological pathways in others. Both ischemic and immunological mechanisms have been demonstrated in the pathogenesis of epileptic seizures, which may account for 7% of neurological manifestations in APS. Although frequent in APS, a causative link between APLab and most common types of headache (migraine and tension-type headache) is more than dubious. Cognitive impairment may derive from a well-defined clinical tableau of multi-infarct dementia. Nevertheless, (highly frequent) less severe cognitive impairment has also been associated with the presence of APLab in the absence of magnetic resonance findings. A relationship between APS and transverse myelopathy seems likely but small numbers in the studies published to date preclude definite statements; routinely testing for APLab patients with neurological manifestations suggestive of multiple sclerosis seems to be unrecommended at the present time.

Abstract
Neuropsychiatric syndromes associated with systemic lupus erythematosus are common, but diverse in etiology and presentation. Cognitive dysfunction is prevalent among these syndromes, but exhibit a significant degree of heterogeneity both within and between patient variability. Earlier studies of SLE-associated cognitive dysfunction addressed its identification and description. Common associations were repeatedly acknowledged, including concomitant or past neuropsychiatric disease, use of corticosteroids, disease activity, emotional disturbance, and antiphospholipid antibodies. The past several years have focused more on elucidating the relative strengths of various risk associations, patterns of cognitive abnormalities, both cross-sectionally and longitudinally (, clinical course), and novel means to identify cognitive impairment, both functionally and biologically.

Abstract
The correct diagnosis of central and peripheral nervous system manifestations in patients with systemic lupus erythematosus (SLE) can be challenging because of many SLE-related and non-SLE-related processes that can be present in a patient. The American College of Rheumatology (ACR) has published case definitions for 19 neuropsychiatric SLE (NPSLE) syndromes, with careful attention to important exclusion criteria. These criteria were developed for research purposes but can be helpful to clinicians with a patient who has nervous system dysfunction. This report reviews the data regarding the application of the ACR NPSLE criteria and the influence of ethnicity and disease duration on the development of NPSLE syndromes. Cognitive dysfunction and psychiatric disorders are the two most common manifestations. The work-up and treatment of nervous system syndromes are also discussed.

Abstract
The aim of the present study was to investigate the role of antinuclear and antiphospholipid antibodies in the pathogenesis of systemic lupus erythematosus (SLE) with demyelinating syndrome and several forms of multiple sclerosis (MS). Paired samples of serum and cerebrospinal fluid (CSF) were investigated using laser nephalometric and enzyme linked immunosorbant assay (ELISA) methods, and the parameters of intrathecal synthesis were calculated. Elevation of the concentrations of antiribosomal P protein antibodies in the CSF and serum, and intrathecal synthesis anticardiolipin (aCL) antibodies were characteristic in all patient groups. The immunoserological changes were more pronounced in the SLE patients. A similar pathogenetic role of antiphospholipid antibodies in central nervous system (CNS) damage in SLE patients with demyelinating syndrome and of MS patients can be assumed.

Abstract
The chronic, lupus-like autoimmune disease in MRL-lpr mice is associated with leucocyte infiltration into the choroid plexus, brain cell death, and deficits in motivated behavior. The presence of lymphoid cells in the ventricular lumen and the increased number of TUNEL-positive cells in periventricular areas led to the hypothesis that immune cells enter into the cerebrospinal fluid (CSF) and induce primary neuronal damage in regions bordering the cerebral ventricles. Using an in vitro approach, we presently examine the possibility that CSF from autoimmune mice is neurotoxic and/or gliotoxic. The CSF and serum from diseased MRL-lpr mice, less symptomatic MRL +/+ controls, and healthy Swiss/Webster mice (non-autoimmune controls) were frozen until their effects on the viability of pyramidal neurons and astrocytes were assessed in a two-color fluorescence assay. Significant reduction in neuronal viability (in some cases as low as 67%) was observed in the co-cultures of hippocampal neurons and astrocytes incubated for 24 h with CSF from autoimmune MRL-lpr mice. The viability of astrocytes did not differ among the groups, and the CSF from autoimmune mice appeared more toxic than the serum. The behavior of MRL-lpr mice differed significantly from the control groups, as indicated by impaired exploration, reduced intake of palatable food, and excessive immobility in the forced swim test. The present results suggest that CSF from the behaviorally impaired lupus-prone mice is neurotoxic and are consistent with the hypothesis that neuroactive metabolites are produced intrathecally in neuropsychiatric lupus erythematosus.
