| Title |
Gene expression after infection of mice with Y. enterocolitica pYV+, lethal dose |
| Sample type |
RNA |
| |
|
| Source name |
CD11b+ cells of the spleen, infected of mice with Y. enterocolitica pYV+, lethal dose
|
| Organism |
Mus musculus |
| Characteristics |
Age: 6-8 weeks old
Gender: female
Strain: C57BL/6 mice
infected with Y. enterocolitica WA-314 (pYV+), lethal dose for one day
|
| Treatment protocol |
Mice were infected intravenously with 50000 Y. enterocolitica WA-314 (pYV+), lethal dose, for one day. After one day, five to ten mice per group were sacrificed by CO2 asphyxiation. The spleens were removed and placed in ice-cold HBSS (Ca2+ and Mg2+ free Hanks’ balanced salt solution [HBSS; BioWhittaker,Walkersville, MD.] supplemented with 2% FCS [HyClone, Logan, Utah] and 10 mM HEPES buffer). The spleens were forced with a 5 ml syringe pestle through a 100 µm-pore nylon mesh cell strainer (Falcon; BD Biosciences). Red blood cells were lysed from spleen samples by incubating the cell suspensions for 5 min at room temperature in erythrocyte lysis buffer (170 mM Tris, 160 mM NH4Cl, pH 7,4) followed by two washes in ice-cold HBSS. CD11b+ cells were purified by positive selection using MACS® CD11b MicroBeads (Miltenyi Biotec) according to the manufacturer´s instructions. To ensure enrichment values of 96-98% purity, the magnetic separation was performed twice. Cell viability and number were assessed by trypan blue exclusion.

| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted from CD11b+ cells using the RNAeasy mini-kit following the manufacturer´s instructions (Qiagen, Hilden, Germany). Generation of fragmented cRNA was performed as recently described [38] and used for hybridization onto MG-U74Av2 from Affymetrix (Affymetrix, High Wycombe, UK). Genechips were washed, stained with streptavidin–phycoerythrin and read using a GeneChip Scanner 2500 (Affymetrix) at the IZKF microarray facility, Tübingen.
