CCR3 knockdown attenuates prolonged underwater operation-induced cognitive impairment via alleviating microglia-mediated neuroinflammation

Project description:It is important to maintain cognitive integrity during underwater operations, which may also trigger cognitive alterations. Cognitive effect of underwater operations and the underlying mechanism remain elusive. Here, we found a single underwater operation affects cognition in a time-dependent model. Prolonged exposure elicits significant cognitive impairment and hippocampal dysfunction, which was accompanied by activation of microglia and upregulation of pro-inflammatory cytokines. RNA-sequencing supported the involvement of neuroinflammation and indicated the critical role of CCR3. Knockdown of CCR3 significantly rescued cognitive impairment and hippocampal dysfunction. Furthermore, the upregulation of pro-inflammatory cytokines was also reversed. Mechanistically, CCR3 knockdown switched the activated microglia from a pro-inflammatory to neuroprotective phenotype. Taken together, these results highlighted the time-dependent effects of a single underwater operation on cognitive function. Knocking down CCR3 can attenuate neuroinflammation by regulating polarization of activated microglia, thereby alleviating prolonged underwater operation-induced cognitive impairment.

Protistan metabolism across the western North Atlantic Ocean revealed through autonomous underwater profiling

Project description:An Autonomous Underwater Vehicle (AUV) and large volume underwater pumps were used to collect microbial biomass from offshore waters of the Sargasso Sea, from surface waters and into the deep ocean. Seawater collection was performed along a transect in the western North Atlantic Ocean beginning near Bermuda and ending off the coast of Massachusetts, capturing metabolic signatures from oligotrophic, continental margin, and productive coastal ecosystems.

Microarray Analysis of Retinal Endothelial Tip Cells Identifies CXCR4 as a Mediator of Tip Cell Morphology and Branching

Project description:The development of the vertebrate vascular system is mediated by both genetic patterning of vessels and by angiogenic sprouting in response to hypoxia. Both of these processes depend on the detection of environmental guidance cues by endothelial cells. A specialized subtype of endothelial cell known as the tip cell is believed to be involved in the detection and response to these cues, but the molecular signaling pathways utilized by tip cells to mediate tissue vascularization remain largely uncharacterized. To identify genes critical to tip cell function, we have developed a method to isolate them using laser capture microdissection, permitting comparison of RNA extracted from endothelial tip cells to that of endothelial stalk cells using microarray analysis. Genes enriched in tip cells include ESM-1, Angiopoietin-2, and SLP-76. CXCR4, a receptor for the chemokine SDF-1, was also identified as a tip cell-enriched gene, and we provide evidence for a novel role for this receptor in mediating tip cell morphology and vascular patterning in the neonatal retina.
