Few genes, like amyloid beta (A4) precursor protein (App), bcl2/adenovirus e1b interacting protein 3-like (Bnip3l), baculoviral IAP repeat-containing 6 (Birc6) and Spn were upregulated throughout the study and few others such as amyloid beta (A4) precursor-like protein 1 (Aplp1), Clusterin (Clu), integral membrane protein 2B (Itm2b), and valosin containing protein (Vcp), were upregulated as early as 48 hr post infection (Table 4). The gene discussed is CLU; the disease is infection.
