The skin is not merely a physical barrier but also an active immunological interface, exposed to various external stimuli including microbes. Over the recent years, our laboratory has defined hair follicles as control towers that regulates immune cells residing in the skin. Hair follicles produce chemokines and cytokines that are crucial for the localization and tissue-residency of immune cells including the Langerhans cells, resident memory T cells, and innate lymphoid cells.

Background: Although the merely cutaneous, benign form of the extremely rare disease atrophic papulosis (Köhlmeier-Degos disease) may occasionally develop into the systemic, malignant form with time, it is unclear whether it itself exhibits any systemic characteristics.

Objective: To determine whether benign atrophic papulosis exhibits inflammatory and thrombo-occlusive signals and to classify it according to the Chapel-Hill classification of vasculitis.

Methods: In a monocentric, controlled study, levels of cytokines (IL-1β, IL-6, IL-8, IFNγ, MCP-1, VEGF, TNFα, TGF-β1), antiphospholipid antibodies (cardiolipin IgG/A/M, cardiolipin IgG, cardiolipin IgM, β2-glycoprotein IgG/A/M, phosphatidyl choline, phosphatidyl serine, phosphatidyl inositol, phosphatidyl ethanolamine and sphingomyelin A), antibodies against proteinase-3 IgG and myeloperoxidase IgG, antinuclear antibodies and extractable nuclear antigen were assessed in blood samples of six benign atrophic papulosis patients and six age- and sex-matched healthy controls.

Chronic Levodopa therapy, the gold-standard treatment for Parkinson's Disease (PD), leads to the emergence of involuntary movements, called levodopa-induced dyskinesia (LID). Cerebellar stimulation has been shown to decrease LID severity in PD patients. Here, in order to determine how cerebellar stimulation induces LID alleviation, we performed daily short trains of optogenetic stimulations of Purkinje cells (PC) in freely moving LID mice.

Kohlmeier-Degos Disease is a unique thrombotic microvascular and arteriopathic vasculopathy that is highly selective in the organs it targets. It invariably involves the skin and can be a purely cutaneous process. It affects both the microvasculature and the arterial system ranging from a thrombogenic microangiopathy to a fibrointimal obliterative arteriopathy with an accompanying background of extravascular fibrosis.

This study compares two methods to quantify the amplitude and frequency of head movements in patients with head tremor: one based on video-based motion analysis, and the other using a miniature wireless inertial magnetic motion unit (IMMU). Concomitant with the clinical assessment of head tremor severity, head linear displacements in the frontal plane and head angular displacements in three dimensions were obtained simultaneously in forty-nine patients using one video camera and an IMMU in three experimental conditions while sitting (at rest, counting backward, and with arms extended). Head tremor amplitude was quantified along/around each axis, and head tremor frequency was analyzed in the frequency and time-frequency domains. Read More

Malignant atrophic papulosis (MAP), or systemic Degos disease, is an obliterative vasculopathy of unknown origin, characterized by erythematous papules found on the skin, central nervous system (Neuro-MAP) and gastrointestinal tract. Neurological involvement occurs in approximately 20% of systemic cases, is progressive and largely fatal. It can be described in two forms: 1) the parenchymal presenting with meningoencephalitis and meningomyelitis and 2) the neurovascular presenting with large cerebral infarcts, intracranial and subarachnoid hemorrhage, subdural hematoma and venous sinus thrombosis.

Abstract: Dowling-Degos Disease (DDD) is a rare and disfiguring autosomal dominant genodermatosis characterized by reticulate hyperpigmented macules or follicular comedone-like papules in the intertriginous areas that typically presents in the third or fourth decade of life. It is a progressive disease that is often treatment-resistant. Although its association with hidradenitis suppurativa has been well described, DDD has also been less commonly reported in conjunction with other dermatologic diseases with unknown etiologic associations.

Current quantification methods of I-FP-CIT SPECT rely on anatomical parcellation of the striatum. We propose here to implement a new method based on MRI segmentation and functional atlas of the basal ganglia (MR-ATLAS) that could provide a reliable quantification within the sensorimotor, associative, and limbic territories of the striatum. Patients with Parkinson's disease (PD), idiopathic rapid eye movement sleep behavioral disorder (iRBD), and healthy controls underwent I-FP-CIT SPECT, MRI, motor, and cognitive assessments.
