Mesenchymal Stem Cells: Potential in Treatment of Neurodegenerative Diseases.
Abstract Mesenchymal Stem Cells or Marrow Stromal Cells (MSCs) have long been viewed as a potent tool for regenerative cell therapy. MSCs are easily accessible from both healthy donor and patient tissue and expandable in vitro on a therapeutic scale without posing significant ethical or procedural problems. MSC based therapies have proven to be effective in preclinical studies for graft versus host disease, stroke, myocardial infarction, pulmonary fibrosis, autoimmune disorders and many other conditions and are currently undergoing clinical trials at a number of centers all over the world. MSCs are also being exte...

CADASIL and Autoimmunity: Coexistence in a Family with the R169C Mutation at Exon 4 of the NOTCH3 Gene
Conclusion: This is a rare description of the coexistence of autoimmunity in CADASIL patients with possible worsening clinical effects. The study extends the spectrum of atypical presentation of CADASIL. The coexistence of autoimmunity does not necessarily exclude CADASIL, but may cause an additional diagnostic and therapeutic challenge. This autoimmune disorder may have increased the severity of the disease and, additionally, may be related to the pathogenetic mechanisms of CADASIL. It is possible that the NOTCH3 mutation alone is not enough to trigger autoimmunity since, in the case of our family, the R169C mutation has ...

Acute Cerebral Infarction as the Presenting Feature of anti-PL-7 Anti-Synthetase Syndrome (P5.126)
CONCLUSIONS: Anti-PL7 is one of eight known aminoacyl-tRNA synthetase (ARS) antibodies. Emerging evidence would suggest that each ARS antibody has a distinct phenotype. There is one report of acute infarction with cerebral vasculitis and anti-Jo1 ARS autoantibody. This is the first report of stroke in association with anti-PL7 anti-synthetase syndrome. Increased recognition of this disorder will allow for better delineation of the phenotype. Study Supported by:Disclosure: Dr. McNicholas has nothing to disclose. Dr. Henry has nothing to disclose.

A patient with multiple paradoxical emboli
We present a case report of simultaneous pulmonary emboli and paradoxical embolism to the cerebellum causing a stroke and severe ischemia to the left leg. This patient had risk factors for thromboembolic events that included autoimmune disease, cancer, and recent pelvic surgery. The presence of a perforate foramen ovale was suspected on his initial presentation and confirmed with echocardiography. For acute leg ischemia, this patient underwent emergent left common femoral embolectomy. The potential benefit of immediate anticoagulation had to be weighed against the risk of hemorrhagic transformation of his cerebellar stroke...

Hacking The Nervous System
(Photo: © Job Boot) One nerve connects your vital organs, sensing and shaping your health. If we learn to control it, the future of medicine will be electric.When Maria Vrind, a former gymnast from Volendam in the Netherlands, found that the only way she could put her socks on in the morning was to lie on her back with her feet in the air, she had to accept that things had reached a crisis point. “I had become so stiff I couldn’t stand up,” she says. “It was a great shock because I’m such an active person.”It was 1993. Vrind was in her late 40s and working two jobs, athletics coach and a carer for disabled ...

Childhood-onset systemic polyarteritis nodosa and systemic lupus erythematosus: an overlap syndrome?
In conclusion, we described herein a possible overlap syndrome of two autoimmune diseases, where childhood-onset systemic polyarteritis nodosa occurred five years before the childhood-onset systemic lupus erythematosus diagnosis.

Lupus, Selena Gomez's Autoimmune Disease, Explained
In an interview with Billboard magazine this week, Selena Gomez confirmed she's been struggling with an autoimmune disease that forced her to take a step back from her work and cancel tours in 2013 and 2014. "I was diagnosed with lupus, and I’ve been through chemotherapy," she told Billboard. "That’s what my break was really about. I could’ve had a stroke." What is lupus? Similar to other autoimmune diseases, lupus causes the body's immune system to attack its own tissue and organs.  Lupus can be difficult to diagnose because its symptoms -- including joint pain, chronic fati...

Regulation of the epithelial Na+ channel by the mTORC2/SGK1 pathway
The epithelial Na+ channel (ENaC) is decisive for sodium reabsorption by the aldosterone-sensitive distal nephron (ASDN) of the kidney. ENaC is regulated by the serum- and glucocorticoid-inducible kinase 1 (SGK1), a kinase genomically upregulated by several hormones including glucocorticoids and mineralocorticoids. SGK1 is activated by the serine/threonine kinase mammalian target of rapamycin (mTOR) isoform mTORC2. SGK1 knockout (sgk1–/– mice) impairs renal Na+ retention during salt depletion. The mTOR catalytic site inhibitor, PP242, but not mTORC1 inhibitor rapamycin, inhibits ENaC, decreases Na+ flux in isol...

Sphingosine-1-Phosphate (S1P) and S1P Signaling Pathway: Therapeutic Targets in Autoimmunity and Inflammation
Abstract Sphingosine-1-phosphate (S1P) and S1P receptors (S1PR) are ubiquitously expressed. S1P-S1PR signaling has been well characterized in immune trafficking and activation in innate and adaptive immune systems. However, the full extent of its involvement in the pathogenesis of autoimmune diseases is not well understood. FTY720 (fingolimod), a non-selective S1PR modulator, significantly decreased annualized relapse rates in relapsing-remitting multiple sclerosis (MS). FTY720, which primarily targets S1P receptor 1 as a functional antagonist, arrests lymphocyte egress from secondary lymphoid tissues and reduce...

Teaching NeuroImages: HIV-associated cerebral vasculopathy with multiple nodular aneurysms
HIV-associated cerebral vasculopathy with multiple aneurysms has been widely reported in children1 and has to be considered in HIV-infected patients with high CSF viral load, but only few cases in adults have been published so far. Nodular and fusiform aneurysms (figure, A–D) are a typical imaging finding2 that may lead to suspicion of an autoimmune etiology by mimicking polyarteritis nodosa. These aneurysms might carry clinical significance with regard to the risk of subarachnoid or intracerebral hemorrhage, or causing infarction through formation of emboli. Highly active antiretroviral therapy leads to remission of...
