Retinal ischemia can be effectively modeled by permanent bilateral common carotid artery occlusion, which leads to chronic hypoperfusion-induced degeneration in the entire rat retina. The complex pathways leading to retinal cell death offer a complex approach of neuroprotective strategies. In the present review we summarize recent findings with different neuroprotective candidate molecules. We describe the protective effects of intravitreal treatment with: (i) urocortin 2; (ii) a mitochondrial ATP-sensitive K(+) channel opener, diazoxide; (iii) a neurotrophic factor, pituitary adenylate cyclase activating polypeptide; and (iv) a novel poly(ADP-ribose) polymerase inhibitor (HO3089). The retinoprotective effects are demonstrated with morphological description and effects on apoptotic pathways using molecular biological techniques.

Background: Stroke remains a leading cause of mortality and disability among adults. Given the restricted therapeutic window for intravascular interventions and neuroprotection during the acute phase, there has been a growing focus on tissue repair and functional recovery in the subacute and chronic phases after stroke. The pro-inflammatory microglial polarization occurs in subacute and chronic phases after stroke and may represent therapeutic targets for stroke recovery.

Mutations in Leucine-rich repeat kinase 2 (LRRK2) and PTEN-induced kinase 1 (PINK1) are associated with familial Parkinson's disease (PD). LRRK2 phosphorylates Rab guanosine triphosphatase (GTPases) within the Switch II domain while PINK1 directly phosphorylates Parkin and ubiquitin (Ub) and indirectly induces phosphorylation of a subset of Rab GTPases. Herein we have crossed LRRK2 [R1441C] mutant knock-in mice with PINK1 knock-out (KO) mice and report that loss of PINK1 does not impact endogenous LRRK2-mediated Rab phosphorylation nor do we see significant effect of mutant LRRK2 on PINK1-mediated Rab and Ub phosphorylation.

Resveratrol [RES] is a polyphenolic stilbene with therapeutic potential owing to its antioxidant, anti-inflammatory, neuroprotective, and cardioprotective properties. However, the very poor oral bioavailability, fast metabolism, and extremely low stability under physiological conditions pose a severe detriment to the clinical use of RES. This newly developed field of nanotechnology has led to the formulation of RES into nanoformulations with the goal of overcoming metabolicpharmacokinetic limitations and enhancing the targeted transport of RES to the central nervous system [CNS].

Parkinson's disease (PD) is a progressive age-related neurodegenerative disease whose annual incidence is increasing as populations continue to age. Although its pathogenesis has not been fully elucidated, oxidative stress has been shown to play an important role in promoting the occurrence and development of the disease. Long noncoding RNAs (lncRNAs), which are more than 200 nucleotides in length, are also involved in the pathogenesis of PD at the transcriptional level via epigenetic regulation, or at the post-transcriptional level by participating in physiological processes, including aggregation of the α-synuclein, mitochondrial dysfunction, oxidative stress, calcium stabilization, and neuroinflammation.
