Lnk KO and WT macrophages were plated in medium supplemented with M-CSF and induced with zymosan, LPS, CpG, and Pam3CSK4, respectively. After 18 h, supernatants were collected, and levels of (A) TNF-α or (B) IL-6 were measured by ELISA. Each figure shows 1 representative of 4 independent experiments measured in triplicates.
