SFTPD and viral infectious disease: Two general trends could be discerned: proteins functioning in leukotriene biosynthesis (two copies of cotl1, and lta4 h) showed reduced abundance, and proteins related to autophagy, viral infection and macrophage-like cell activity such as atg101 (Mercer et al., 2009), ikbke (Hemmi et al., 2004), ifih1 (Sarmiento et al., 2017), mx2 (Kane et al., 2013), mrc1 (Harris et al., 1992) and sftpd (Holmskov et al., 1999) showed increased abundance.
