Project description:Microarray comparative genome hybridization (mCGH) data was collected from one Neisseria cinerea, two Neisseria lactamica, two Neisseria gonorrhoeae, and 48 Neisseria meningitidis isolates. For N. meningitidis, these isolates are from diverse clonal complexes, invasive and carriage strains, and all major serogroups. The microarray platform represented N. meningitidis strains MC58, Z2491, and FAM18 and N. gonorrhoeae FA1090.
Project description:We looked at host gene expression signatures common and specfic to occasionally pathogenic N. meningitidis and commensal N. lactamica. We hypothesise that similar host cell responses during early interactions with N. meningitidis and N. lactamica could inform common mechanisms of colonisation of commensals while differential host cell responses could be capable of altering the outcome of the colonisation process. Total RNA obtained from 16HBE14 cells infected with the different strains of Neisseria from 0 to 7 hours are compared to mock-infected controls at the respective timepoints. 192 samples are analysed. There are 4 to 8 biological replicates per condition.
