Aggf1 Attenuates Neuroinflammation and BBB Disruption Via PI3K/Akt/NF-Κb Pathway After Subarachnoid Hemorrhage in Rats
Zhu et al. Journal of Neuroinflammation (2018) 15:178 https://doi.org/10.1186/s12974-018-1211-8 RESEARCH Open Access Aggf1 attenuates neuroinflammation and BBB disruption via PI3K/Akt/NF-κB pathway after subarachnoid hemorrhage in rats Qiquan Zhu1,2, Budbazar Enkhjargal2, Lei Huang2,4, Tongyu Zhang2, Chengmei Sun2, Zhiyi Xie2, Pei Wu2, Jun Mo2, Jiping Tang2, Zongyi Xie1* and John H. Zhang2,3,4* Abstract Background: Neuroinflammation and blood-brain barrier (BBB) disruption are two critical mechanisms of subarachnoid hemorrhage (SAH)-induced brain injury, which are closely related to patient prognosis. Recently, angiogenic factor with G-patch and FHA domain 1 (Aggf1) was shown to inhibit inflammatory effect and preserve vascular integrity in non-nervous system diseases. This study aimed to determine whether Aggf1 could attenuate neuroinflammation and preserve BBB integrity after experimental SAH, as well as the underlying mechanisms of its protective roles. Methods: Two hundred forty-nine male Sprague-Dawley rats were subjected to the endovascular perforation model of SAH. Recombinant human Aggf1 (rh-Aggf1) was administered intravenously via tail vein injection at 1 h after SAH induction. To investigate the underlying neuroprotection mechanism, Aggf1 small interfering RNA (Aggf1 siRNA) and PI3K-specific inhibitor LY294002 were administered through intracerebroventricular (i.c.v.) before SAH induction. SAH grade, neurological score, brain water content, BBB permeability, Western blot, and immunohistochemistry were performed. Results: Expression of endogenous Aggf1 was markedly increased after SAH. Aggf1 was primarily expressed in endothelial cells and astrocytes, as well as microglia after SAH. Administration of rh-Aggf1 significantly reduced brain water content and BBB permeability, decreased the numbers of infiltrating neutrophils, and activated microglia in the ipsilateral cerebral cortex following SAH. -
Composition of Herpesvirus Ribonucleoprotein Complexes †
Abstract Composition of Herpesvirus Ribonucleoprotein Complexes † Eric S. Pringle 1,2,* and Craig McCormick 1,2 1 Department of Microbiology and Immunology, Dalhousie University, Halifax, NS B3H 4R2, Canada; [email protected] 2 Beatrice Hunter Cancer Research Institute, Halifax, NS B3H 4R2, Canada * Correspondence: [email protected] † Presented at Viruses 2020—Novel Concepts in Virology, Barcelona, Spain, 5–7 February 2020. Published: 4 July 2020 Abstract: Herpesvirus genomes are decoded by host RNA polymerase enzymes, generating messenger ribonucleotides (mRNA) that are post-transcriptionally modified and exported to the cytoplasm through the combined work of host and viral factors. These viral mRNA bear 5′-m7GTP caps and poly(A) tails that should permit the assembly of canonical host eIF4F cap-binding complexes to initiate protein synthesis. However, the precise mechanisms of translation initiation remain to be investigated for Kaposi’s sarcoma-associated herpesvirus (KSHV) and other herpesviruses. During KSHV lytic replication in lymphoid cells, the activation of caspases leads to the cleavage of eIF4G and depletion of eIF4F. Translating mRNPs depleted of eIF4F retain viral mRNA, suggesting that non-eIF4F translation initiation is sufficient to support viral protein synthesis. To identify proteins required to support viral protein synthesis, we isolated and characterized actively translating messenger ribonucleoprotein (mRNP) complexes by ultracentrifugation and sucrose-gradient fractionation followed by quantitative mass spectrometry. The abundance of host translation initiation factors available to initiate viral protein synthesis were comparable between cells undergoing KSHV lytic or latent replication. The translation initiation factors eIF4E2, NCBP1, eIF4G2, and eIF3d were detected in association with actively translating mRNP complexes during KSHV lytic replication, but their depletion by RNA silencing did not affect virion production. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -
4-6 Weeks Old Female C57BL/6 Mice Obtained from Jackson Labs Were Used for Cell Isolation
Methods Mice: 4-6 weeks old female C57BL/6 mice obtained from Jackson labs were used for cell isolation. Female Foxp3-IRES-GFP reporter mice (1), backcrossed to B6/C57 background for 10 generations, were used for the isolation of naïve CD4 and naïve CD8 cells for the RNAseq experiments. The mice were housed in pathogen-free animal facility in the La Jolla Institute for Allergy and Immunology and were used according to protocols approved by the Institutional Animal Care and use Committee. Preparation of cells: Subsets of thymocytes were isolated by cell sorting as previously described (2), after cell surface staining using CD4 (GK1.5), CD8 (53-6.7), CD3ε (145- 2C11), CD24 (M1/69) (all from Biolegend). DP cells: CD4+CD8 int/hi; CD4 SP cells: CD4CD3 hi, CD24 int/lo; CD8 SP cells: CD8 int/hi CD4 CD3 hi, CD24 int/lo (Fig S2). Peripheral subsets were isolated after pooling spleen and lymph nodes. T cells were enriched by negative isolation using Dynabeads (Dynabeads untouched mouse T cells, 11413D, Invitrogen). After surface staining for CD4 (GK1.5), CD8 (53-6.7), CD62L (MEL-14), CD25 (PC61) and CD44 (IM7), naïve CD4+CD62L hiCD25-CD44lo and naïve CD8+CD62L hiCD25-CD44lo were obtained by sorting (BD FACS Aria). Additionally, for the RNAseq experiments, CD4 and CD8 naïve cells were isolated by sorting T cells from the Foxp3- IRES-GFP mice: CD4+CD62LhiCD25–CD44lo GFP(FOXP3)– and CD8+CD62LhiCD25– CD44lo GFP(FOXP3)– (antibodies were from Biolegend). In some cases, naïve CD4 cells were cultured in vitro under Th1 or Th2 polarizing conditions (3, 4). -
