IL7 and susceptibility to pneumonia measurement: Coronavirus infection with pneumonia positively correlates with pro-inflammatory IFNA2 (p = 0.0051), IL-15 (p = 0.0087), IL-7 (p = 0.0333), sCD40L (p = 0.0336), MCP-1 (p = 0.0001), and anti-inflammatory FGF-2 (p = 0.0066) and negatively correlates with pro-inflammatory MIP-1b (p = 0.049), MIP-1a (p = 0.0093), MDC (p = 0.055), and GM-CSF (p = 0.0045) (Figure 3A,B, Table 2).
