Comparing the transcriptome of naïve C57BL/6 CD44+/+ vs CD44-/- alveolar macrophages
Purpose: Determine if alveolar macrophage express different transcriptional programs when CD44 expression is lost. Methods: Alveolar macrophages were isolated from the bronchoalveolar lavage of 6-10 week old CD44+/+ and CD44-/- female mice. RNA was isolated an  sequenced using Illumina NextSeq 500. RNA was sequenced by the UBC Biomedical Research Center. RNA quality, 18S and 28S ribosomal RNA with RIN = 9.6, was determined by Agilent 2100 Bioanalyzer following standard protocol for NEBnext Ultra ii Stranded mRNA (New England Biolabs). Sequencing was performed on the Illumina NextSeq 500 with paired end 42bp  42bp reads. De-multiplexed read sequences were then aligned to the Mus musculus (mm10) reference sequence using Spliced Transcripts Alignment to a Reference, STAR (https://www.ncbi.nlm.nih.gov/pubmed/23104886), aligners. Results and conclusion: Multiple pathways were abnormal in CD44-/- alveolar macrophages, in particular those involved in lipid metabolism and immune signaling. Overall design: mRNA libraries generated from alveolar macrophages isolated from bronchoalvoelar lavage of 6-10 week old CD44+/+ and CD44-/- female mice, in triplicates, using Illumina NextSeq 500
