COVID-19 is a respiratory tract infection that can affect multiple organ systems. Predicting the severity and clinical outcome of individual patients is a major unmet clinical need that remains challenging due to intra- and inter-patient variability. Here, we longitudinally profiled and integrated more than 150 clinical, laboratory and immunological parameters of 173 patients with mild… Read more »

Complement-associated loss of CA2 inhibitory synapses in the demyelinated hippocampus impairs memory
The complement system is implicated in synapse loss in the MS hippocampus, but the functional consequences of synapse loss remain poorly understood. Here, in post-mortem MS hippocampi with demyelination we find that deposits of the complement component C1q are enriched in the CA2 subfield, are linked to loss of inhibitory synapses and are significantly higher… Read more »
Immunological substrates of depressive symptoms in patients with severe obesity: An exploratory study
In this pilot study, we explored the immune phenotype of patients with severe obesity and comorbid depressive symptoms compared to non-depressed patients with obesity and normal-weight controls. Immune cell subsets were analysed by flow cytometry and depressive symptoms assessed using the Patient Health Questionnaire (PHQ-9). Cell frequencies were correlated with depressive symptom scores and waist-to-hip… Read more »
Pain, Depression, and Quality of Life in Neuromyelitis Optica Spectrum Disorder: A Cross-Sectional Study of 166 AQP4 Antibody-Seropositive Patients
Objectives: To evaluate prevalence, clinical characteristics, and predictors of pain, depression, and their impact on the quality of life (QoL) in a large neuromyelitis optica spectrum disorder (NMOSD) cohort. Methods: We included 166 patients with aquaporin-4-seropositive NMOSD from 13 tertiary referral centers. Patients received questionnaires on demographic and clinical characteristics, PainDetect, short form of Brief… Read more »
Activity-regulated cytoskeleton-associated protein/activity-regulated gene 3.1 (Arc/Arg3.1) enhances dendritic cell vaccination in experimental melanoma
Dendritic cell (DC) vaccination has proven to be an effective and safe adjuvant for cancer immunotherapies. As the presence of DCs within the tumor microenvironment promotes adaptive antitumor immunity, enhancement of DC migration toward the tumor microenvironment following DC vaccination might represent one possible approach to increase its therapeutic efficacy. While recent findings suggest the… Read more »
SnapShot: Neuronal dysfunction in inflammation
Neuronal function relies on tightly controlled cytoskeleton transport with adaptive cargo trafficking as prerequisite for synaptic transmission. During inflammation in multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE), axonal transport efficiency declines, followed by neurodegeneration. Furthermore, neuroinflammation causes an imbalance between excitatory and inhibitory transmission, triggering synaptic dysfunction and loss. Recent data suggest that neuronal… Read more »
