Abstract

Parkinson's disease is a progressive neurodegenerative disorder characterized by the degeneration of midbrain nigral dopaminergic neurons. Although its etiology remains unknown, the pathological role of several factors has been highlighted, namely oxidative stress, neuroinflammation, protein misfolding, and mitochondrial dysfunction, in addition to genetic predispositions. The current therapy is mainly symptomatic with l-DOPA aiming to replace dopamine. Novel therapeutic approaches are being investigated with the intention of influencing pathways leading to neuronal death and dysfunction. The present review summarizes three novel approaches, the use of which is promising in pre-clinical studies. Polyphenols have been shown to possess neuroprotective properties on account of their well-established antioxidative and anti-inflammatory actions but also due to their influence on protein misfolding and mitochondrial homeostasis. Within the amazing ancillary effects of antibiotics, their neuroprotective properties against neurodegenerative and neuroinflammatory processes are of great interest for the development of effective therapies against Parkinson's disease. Experimental evidence supports the potential of antibiotics as neuroprotective agents, being useful not only to prevent the formation of toxic α-synuclein oligomers but also to ameliorate mitochondrial dysfunction and neuroinflammation. Neuropeptides offer another approach with their diverse effects in the nervous system. Among them, pituitary adenylate cyclase-activating polypeptide, a member of the secretin/glucagon superfamily, has several advantageous effects in models of neurodegeneration, namely anti-apoptotic, anti-inflammatory and antioxidant actions, the combination of which offers a potent protective effect in dopaminergic neurons. Owing to their pleiotropic modes of action, these novel therapeutic candidates have potential in tackling the multidimensional features of Parkinson's disease.

  • Beta-lactams (cephalosporin antibiotics) have been shown to be effective in the treatment and alleviation of ND symptoms and in the treatment of experimentally induced neurological disorders such as PD, AD, ALS, traumatic brain injury, epilepsy, cerebral ischemia, and neuropathy.

    “In particular, beta-lactams (cephalosporin antibiotics) have been shown to be effective in the treatment and alleviation of ND symptoms and in the treatment of experimentally induced neurological disorders such as PD, AD, ALS, traumatic brain injury (TBI), epilepsy, cerebral ischemia, and neuropathy (84, 117, 118).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
