The positive impact on translational research of Fondazione italiana di ricerca per la Sclerosi Laterale Amiotrofica (AriSLA), a non-profit foundation focused on amyotrophic lateral sclerosis. Convergence of ex-ante evaluation and ex-post outcomes when goals are set upfront.

Charities investing on rare disease research greatly contribute to generate ground-breaking knowledge with the clear goal of finding a cure for their condition of interest. Although the amount of their investments may be relatively small compared to major funders, the advocacy groups' clear mission promotes innovative research and aggregates highly motivated and mission-oriented scientists. Here, we illustrate the case of Fondazione italiana di ricerca per la Sclerosi Laterale Amiotrofica (AriSLA), the main Italian funding agency entirely dedicated to amyotrophic lateral sclerosis research.

Altered intracellular localization of SOD1 in leukocytes from patients with sporadic amyotrophic lateral sclerosis.

Several lines of evidence support the hypothesis of a toxic role played by wild type SOD1 (WT-SOD1) in the pathogenesis of sporadic amyotrophic lateral sclerosis (SALS). In this study we investigated both distribution and expression profile of WT-SOD1 in leukocytes from 19 SALS patients and 17 healthy individuals. Immunofluorescence experiments by confocal microscopy showed that SOD1 accumulates in the nuclear compartment in a group of SALS subjects.

An over-oxidized form of superoxide dismutase found in sporadic amyotrophic lateral sclerosis with bulbar onset shares a toxic mechanism with mutant SOD1.

Recent studies suggest that Cu/Zn superoxide dismutase (SOD1) could be pathogenic in both familial and sporadic amyotrophic lateral sclerosis (ALS) through either inheritable or nonheritable modifications. The presence of a misfolded WT SOD1 in patients with sporadic ALS, along with the recently reported evidence that reducing SOD1 levels in astrocytes derived from sporadic patients inhibits astrocyte-mediated toxicity on motor neurons, suggest that WT SOD1 may acquire toxic properties similar to familial ALS-linked mutant SOD1, perhaps through posttranslational modifications. Using patients' lymphoblasts, we show here that indeed WT SOD1 is modified posttranslationally in sporadic ALS and is iper-oxidized (i.

G93A SOD1 alters cell cycle in a cellular model of Amyotrophic Lateral Sclerosis.

Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative multifactorial disease characterized, like other diseases such as Alzheimer's disease (AD), Parkinson's disease (PD) or frontotemporal dementia (FTD), by the degeneration of specific neuronal cell populations. Motor neuron loss is distinctive of ALS. However, the causes of onset and progression of motor neuron death are still largely unknown.

ALS-linked mutant SOD1 damages mitochondria by promoting conformational changes in Bcl-2.

In mutant superoxide dismutase (SOD1)-linked amyotrophic lateral sclerosis (ALS), accumulation of misfolded mutant SOD1 in spinal cord mitochondria is thought to cause mitochondrial dysfunction. Whether mutant SOD1 is toxic per se or whether it damages the mitochondria through interactions with other mitochondrial proteins is not known. We previously identified Bcl-2 as an interacting partner of mutant SOD1 specifically in spinal cord, but not in liver, mitochondria of SOD1 mice and patients.

Time course of oxidant markers and antioxidant defenses in subgroups of amyotrophic lateral sclerosis patients.

Oxidative stress markers have been found in nervous and peripheral tissues of familial and sporadic amyotrophic lateral sclerosis patients. Here, we evaluated the activity of some antioxidant enzymes glutathione peroxidase, glutathione reductase and Cu-Zn superoxide dismutase in erythrocyte, the marker of non-enzymatic antioxidant response (total antioxidant status), as well as plasma reactive oxygen species, at the enrolment and during disease progression in 88 patients affected by the sporadic form of amyotrophic lateral sclerosis. Our study has been performed along 72 months by grouping the patients according to the ALS functional rating score or rate of disease progression.

TNF and sTNFR1/2 plasma levels in ALS patients.

The involvement of the immune system has been hypothesized in the pathogenesis of amyotrophic lateral sclerosis (ALS). In this study a significantly higher level of TNF-alpha and its soluble receptors, TNF-R1 and TNF-R2, has been found in plasma of patients affected by the sporadic form of ALS compared to normal subjects. The genetic analysis of the polymorphisms of TNF-alpha, TNF-R1 and TNF-R2 showed no statistically significant differences in alleles and genotype frequencies between patients and controls.
