Post-CNS-inflammation expression of CXCL12 promotes the endogenous myelin/neuronal repair capacity following spontaneous recovery from multiple sclerosis-like disease

J Neuroinflammation. 2016 Jan 8;13(1):7. doi: 10.1186/s12974-015-0468-4.

These data link CXCL12 expression in the DG and CC of EAE-recovering mice to the promotion of neuro/oligodendrogenesis generating CXCR4+ CXCL12+ neuronal and oligodendrocyte progenitor cells endowed with intrinsic neuro/oligondendroglial differentiation potential. These findings highlight the post-CNS-inflammation role of CXCL12 in augmenting the endogenous myelin/neuronal repair capacity in MS-like disease, likely via CXCL12/CXCR4 autocrine signaling.

CTLA4 as Immunological Checkpoint in the Development of Multiple Sclerosis.

Ann Neurol. 2016 Aug;80(2):294-300. doi: 10.1002/ana.24715.

We investigated a patient who developed multiple sclerosis (MS) during treatment with the CTLA4-blocking antibody ipilimumab for metastatic melanoma. Initially he showed subclinical magnetic resonance imaging (MRI) changes (radiologically isolated syndrome). Two courses of ipilimumab were each followed by a clinical episode of MS, 1 of which was accompanied by a massive increase of MRI activity. Brain biopsy confirmed active, T-cell type MS. Quantitative next generation sequencing of T-cell receptor genes revealed distinct oligoclonal CD4(+) and CD8(+) T-cell repertoires in the primary melanoma and cerebrospinal fluid. Our results pinpoint the coinhibitory molecule CTLA4 as an immunological checkpoint and therapeutic target in MS. Ann Neurol 2016;80:294-300. [mehr...]

Distinct oligoclonal band antibodies in multiple sclerosis recognize ubiquitous self-proteins.

Proc Natl Acad Sci U S A. 2016 Jul 12;113(28):7864-9. doi: 10.1073/pnas.1522730113.

Oligoclonal band (OCB) antibodies from the cerebrospinal fluid of patients with multiple sclerosis are important diagnostic tools, but their antigens and their role in the pathogenesis were so far unknown. To identify antigens of OCB we developed a new technology that allowed us to produce recombinant antibodies resembling distinct OCB. We identified three target antigens. All of them were ubiquitous intracellular proteins not specific to brain tissue suggesting that at least these OBC were involved in secondary immune reactions, i.e. in removal of cellular debris, rather than attacking autologous tissue in a specific primary immune reaction.

We analyzed the immunopathology of Rasmussen encephalitis, a rare pediatric epilepsy, by deep sequencing of T cell receptor chains. We identified public T cell clones, i.e. clones that are shared between different patients. This suggests that antigen-driven T cell expansions are a major cause of the lymphocyte attack against brain tissue. [mehr...]

Cryopyrin-associated periodic fever syndrome manifesting as Tolosa-Hunt syndrome

Cephalalgia. 2016 Feb 3. pii: 0333102416629239. [Epub ahead of print]

Tolosa-Hunt syndrome (THS) is characterized by unilateral orbital pain, ipsilateral oculomotor paresis and a prompt response to treatment with corticosteroids. We report the case of a patient diagnosed with THS after an episode of unilateral orbital pain and diplopia with demonstration of granulomatous inflammation of both cavernous sinus on cerebral magnetic resonance imaging and an immediate response to treatment with corticosteroids. Progression of the disease over the following years, accompanied by increasing signs of inflammation on cerebral magnetic resonance imaging and cerebrospinal fluid pleocytosis, led to further diagnostic tests. Genetic analyses revealed a heterozygote low-penetrance mutation (Q703K) of the cryopyrin/NLRP3 gene compatible with a cryopyrin-associated periodic fever syndrome. This case report demonstrates that THS can be a central nervous system manifestation of cryopyrin-associated periodic fever syndrome, which therefore represents a differential diagnosis of THS, even in elderly patients.

Fingolimod induces neuroprotective factors in human astrocytes

J Neuroinflammation. 2015 Sep 30;12:184. doi: 10.1186/s12974-015-0393-6.

Fingolimod is the first sphingosine-1-phosphate receptor modulator approved for the treatment of multiple sclerosis. It reduces brain atrophy and neuroprotective effects are hypothesized. We identified effects of fingolimod on astrocytes, namely induction of neurotrophic mediators (LIF, HBEGF, and IL11) and inhibition of TNF-induced inflammatory genes (CXCL10, BAFF, MX1, and OAS2). This supports the view that a part of the effects of fingolimod may be mediated via astrocytes. [mehr...]

Although the importance of reactive astrocytes during CNS pathology is well established, the function of astroglia in adult CNS homeostasis is less well understood. With the use of conditional, astrocyte-restricted protein synthesis termination, we found that selective paralysis of GFAP(+) astrocytes in vivo led to rapid neuronal cell loss and severe motor deficits.

We evaluated the frequency of the cryoporin/NLRP3 low-penetrance mutations V198M and Q703K in patients who reported at least 2 symptoms compatible with cryopyrin-associated periodic syndromes (CAPS) and characterized the phenotype in mutation-positive patients. Seventeen patients (16%) tested positive for either of the 2 mutations (V198M: n = 2; Q703K: n = 15). Eleven patients (65%) had severe headache syndromes. Six of these 11 patients were diagnosed with migraine. Nine patients (53%) had a concomitant diagnosis of multiple sclerosis (MS). In 3 patients, we identified additional family members with the respective mutation as well as the diagnosis of MS. Severe recurrent cranial nerve (CN) affection was the hallmark feature in 7 of the 8 (88%) non-MS mutation carriers. Brain MRI showed abnormalities in all but 2 patients (88%) and detected CN inflammation in 4 patients. Interleukin-6 was elevated in the CSF of 2 patients in the non-MS cohort during acute CAPS episodes with severe CNS inflammation. 5 of 9 treated patients (56%) responded to anti-interleukin-1 therapy. CAPS constitute rare but treatable and commonly misdiagnosed autoinflammatory syndromes. Our data expand the spectrum of CAPS-associated neurologic manifestations. They also broaden our concept of autoimmunity and autoinflammation by linking CAPS and MS. [mehr...]

FGF22 signaling regulates synapse formation during post-injury remodeling of the spinal cord

EMBO J. 2015 Mar 12. pii: e201490578. [Epub ahead of print]

Following spinal cord injury, transected projections form detour circuits that circumvent the lesion and contribute to functional recovery. The formation of new synaptic contacts is a crucial step of the process, but its molecular regulation is currently not understood. Here, we show that: • FGF22 and FGF22 receptors are expressed in the adult nervous system. • FGF22 deficiency or deletion of FGF22 receptors restricts the formation and maturation of new synapses in the injured spinal cord. • Genetic disruption of FGF22 signaling impedes spontaneous functional recovery following spinal cord injury.

During this time the intra-axonal calcium dynamics determine the axonal fate. Those axons that manage to re-establish calcium homoestasis will survive longterm while those that fail to do so will degenerate.
