Corrigendum: Top-Down Proteomics of Human Saliva Highlights Anti-inflammatory, Antioxidant, and Antimicrobial Defense Responses in Alzheimer Disease

Alzheimer disease (AD) is the most prevalent neurodegenerative disease in the elderly, characterized by accumulation in the brain of misfolded proteins, inflammation, and oxidative damage leading to neuronal cell death. By considering the viewpoint that AD onset and worsening may be influenced by environmental factors causing infection, oxidative stress, and inflammatory reaction, we investigated the changes of the salivary proteome in a population of patients with respect to that in healthy controls (HCs). Indeed, the possible use of saliva as a diagnostic tool has been explored in several oral and systemic diseases. Moreover, the oral cavity continuously established adaptative and protective processes toward exogenous stimuli. In the present study, qualitative/quantitative variations of 56 salivary proteoforms, including post-translationally modified derivatives, have been analyzed by RP-HPLC-ESI-IT-MS and MS/MS analyses, and immunological methods were applied to validate MS results. The salivary protein profile of AD patients was characterized by significantly higher levels of some multifaceted proteins and peptides that were either specific to the oral cavity or also expressed in other body districts: (i) peptides involved in the homeostasis of the oral cavity; (ii) proteins acting as ROS/RNS scavengers and with a neuroprotective role, such as S100A8, S100A9, and their glutathionylated and nitrosylated proteoforms; cystatin B and glutathionylated and dimeric derivatives; (iii) proteins with antimicrobial activity, such as α-defensins, cystatins A and B, histatin 1, statherin, and thymosin β4, this last with a neuroprotective role at the level of microglia. These results suggested that, in response to injured conditions, Alzheimer patients established defensive mechanisms detectable at the oral level.

Pain and inflammation are the basic defense responses of the body that the result of the injury and any other damage to the body. During the years the concerns were raised towards the inflammation that is caused to the oxidative damage that is resulted in the physiological stress due to oxidation. There are a lot of drugs that are used to treat the condition effectively and the typical examples are NSAID’s and SAID’s which have a noted mechanism to show the anti-inflammatory activity. They have serious problems with the side effects like Gastrointestinal irritation, Gastric pain, Gastric perforations and peptic ulcers. Herbs have been used as better alternatives that are used to treat diseases. The significance of the medicinal plants had been emphasized significantly in tradition rich countries like India and all over the world. The research proof of those herbs for their activities and their traditional claims were proven. Poly Herbal Gels were prepared using the root extracts of the plant Corchorus olitorius. The gels were prepared using the Carbopol 940 and the prepared gels were investigated for their anti-inflammatory property and the gels showed a significantly better activity compared to the plant extract and the standard drug too. The addition of other drugs in to the gels added and advantage to the increase in the activity and faster onset of action as the gel was applied directly in the place of the inflammation.
