Caffeic Acid Phenethyl Ester Protects Neurons Against Oxidative Stress and Neurodegeneration During Traumatic Brain Injury

Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe authors aimed to evaluate the effect of caffeic acid phenethyl ester (CAPE), an inhibitor of NF-κB, on Fg-induced neurodegeneration in vitro and in mice with mild-to-moderate TBI.
The manuscript has good scientific facts.
The first keyword may be checked from MeSH database.
In the introduction section, please add the sentence- “CAPE has been reported to have anti-inflammatory, antioxidant, neuroprotective, antiviral, antitumoral, antiatherosclerotic, and immunomodulatory properties in a variety of systems”
Does coagulopathy occur in TBI? Possibly due to a combination of hemorrhage and trauma induced coagulopathy, there can be low fibrinogen levels with severe TBI.
Refer to line 346- Instead of using a general term ‘protect blood-brain integrity’ please use the exact word. Does CAPE effectively reduce blood-brain permeability?
Can CAPE may improve BBB integrity by preserving claudin-5 levels? Please discuss this fact.
What is the effect on hippocampal cell loss?
Regarding the neuroprotection offered by CAPE, can the degree of inflammation influence the results?

Reviewer 2 Report
Comments and Suggestions for AuthorsThis manuscript is interesting on the relevant issue of neuroprotection, the study is well designed and the text shows important results; I have only a minor suggestion: The title is too long, the line “The role of fibrinogen” could be deleted as the authors did not demonstrate (P8, L308-318) the role of fibrinogen on their results; also, the term “Caffeic acid” would lead to think that caffeine from coffee is proposed (P14,L455-458), I think that the term should be changed from the title (e.g. “A polyphenol…”)
