Moreover, quantitative RT-PCR and ELISA performed in the LMMP of WT mice at 1–3 weeks post IG infection revealed increased mRNA and protein levels of CCL2, a chemoattractant factor involved in macrophage-driven tissue damage (Gosling et al., 1999; Huang et al., 2001; Brun et al., 2018). The gene discussed is CCL2; the disease is infection.
