The trauma resulted in decreased expression of CB1-R and increased expression of CB2-R in the cortex, striatum, and hippocampus. Cortical and striatal levels of the major endocannabinoid ligand, 2-arachidonoyl-glycerol, were also increased by the CCI. Administration of the hematopoietic cytokine, G-CSF, following TBI, resulted in mitigation or reversal of trauma-induced CB1-R downregulation and CB2-R upregulation in the three brain regions. Treatment with CB1-R agonist (WIN55) or CB2-R agonist (HU308) mimicked the effects of G-CSF. (ii) Pharmacological blockade of CB1-R or CB2-R was not effective in preventing G-CSF's mitigation or reversal of trauma-induced alterations in these receptors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>These results suggest that cellular and molecular mechanisms that mediate subacute effects of G-CSF do not depend on activation of CB1 or CB2 receptors. Failure of selective CB receptor antagonists to prevent the effects of G-CSF in this model has to be accepted with caution. CB receptor antagonists can interact with other CB and non-CB receptors. Investigation of the role of CB receptors in this TBI model will require studies with CB1-R and in CB2-R knockout mice to avoid nonspecific interaction of CB receptor agents with other receptors.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/can.2019.0090","type":"journal-article","created":{"date-parts":[[2020,2,18]],"date-time":"2020-02-18T17:03:02Z","timestamp":1582045382000},"page":"48-57","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Granulocyte Colony-Stimulating Factor Enhances Brain Repair Following Traumatic Brain Injury Without Requiring Activation of Cannabinoid Receptors"],"prefix":"10.1177","volume":"6","author":[{"given":"Shijie","family":"Song","sequence":"first","affiliation":[{"name":"James Haley VA Medical Center, Tampa, Florida, USA."},{"name":"Department of Neurology and University of South Florida, Tampa, Florida, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoyuan","family":"Kong","sequence":"additional","affiliation":[{"name":"James Haley VA Medical Center, Tampa, Florida, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cesar","family":"Borlongan","sequence":"additional","affiliation":[{"name":"James Haley VA Medical Center, Tampa, Florida, USA."},{"name":"Department of Neurosurgery, University of South Florida, Tampa, Florida, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vasyl","family":"Sava","sequence":"additional","affiliation":[{"name":"James Haley VA Medical Center, Tampa, Florida, USA."},{"name":"Department of Neurology and University of South Florida, Tampa, Florida, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan","family":"Sanchez-Ramos","sequence":"additional","affiliation":[{"name":"Department of Neurology and University of South Florida, Tampa, Florida, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,2,12]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5381.2011.01343.x"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/nrn1247"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.pharmtox.46.120604.141254"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1194\/jlr.M094664"},{"key":"e_1_3_3_6_2","first-page":"10","article-title":"Omega-3 endocannabinoid-epoxides are novel anti-inflammatory and anti-pain lipid metabolites","volume":"3","author":"Das A","year":"2019","unstructured":"Das A, , Watson J, , Carnevale L, et al.
