Meanwhile, anti-inflammatory factors such as TNFAIP3, NFKBIA, NFKBIZ, SOCS1, SOCS3, and IL-10 were elevated, with the reverse trends for the inflammation-inducing genes PPBP and MARCO at 38 hpi, suggesting that the pro- and anti-inflammatory responses might coexist in PAMs during YC-2020 infection. The gene discussed is MARCO; the disease is infection.
