Dysfunction of the unfolded protein response increases neurodegeneration in aged rat hippocampus following proteasome inhibition
(Wiley-Blackwell, 2009)
Dysfunctions of the ubiquitin proteasome system (UPS) have been proposed to be involved in the aetiology and/or progression of several age-related neurodegenerative disorders. However, the mechanisms linking proteasome ...

Regional difference in inflammatory response to LPS-injection in the brain: Role of microglia cell density
(Elsevier, 2011)
To elucidate whether density of cells could contribute to the extent of microglial activation, we performed in vitro assays using three different densities of N13 microglia stimulated with LPS. Our results showed that ...

Learning improvement after PI3K activation correlates with de novo formation of functional small spines
(Frontiers Media S.A., 2014)
PI3K activation promotes the formation of synaptic contacts and dendritic spines, morphological features of glutamatergic synapses that are commonly known to be related to learning processes. In this report, we show that ...

Abnormal accumulation of autophagic vesicles correlates with axonal and synaptic pathology in young Alzheimer’s mice hippocampus
(Springer, 2012)
Dystrophic neurites associated with amyloid plaques precede neuronal death and manifest early in Alzheimer’s disease (AD). In this work we have characterized the plaque-associated neuritic pathology in the hippocampus ...

Proteostasis Dysfunction in Aged Mammalian Cells. The Stressful Role of Inflammation
(Frontiers Media S.A., 2021)
Aging is a biological and multifactorial process characterized by a progressive and irreversible deterioration of the physiological functions leading to a progressive increase in morbidity. In the next decades, the world ...

Neuroinflammation alters cellular proteostasis by producing endoplasmic reticulum stress, autophagy activation and disrupting ERAD activation
(Nature Publishing Group, 2017)
Proteostasis alteration and neuroinflammation are typical features of normal aging. We have previously shown that neuroinflammation alters cellular proteostasis through immunoproteasome induction, leading to a transient ...

SIRT1 activation with neuroheal is neuroprotective but SIRT2 inhibition with AK7 is detrimental for disconnected motoneurons
(Springer Nature, 2018)
Sirtuin 1 (SIRT1) activity is neuroprotective, and we have recently demonstrated its role in the retrograde degenerative process in motoneurons (MNs) in the spinal cord of rats after peripheral nerve root avulsion (RA) ...

Molecular and pharmacological characterization of native cortical γ- aminobutyric acids receptors containing both α1 and α3 subunits
(1996)
We have investigated the existence, molecular composition, and benzodiazepine binding properties of native cortical α1-α3 γ- aminobutyric acid(A) (GABA(A)) receptors using subunit-specific antibodies. The co-existence of ...
